Kinds of Abdominal Surgery Selected AbstractsRISK FACTORS FOR POSTOPERATIVE PULMONARY COMPLICATIONS IN UPPER ABDOMINAL SURGERYANZ JOURNAL OF SURGERY, Issue 3 2007Fikret Kanat Background: Pulmonary complications are the most frequent cause of postoperative morbidity and mortality in upper abdominal surgery (UAS). We aimed to examine the influence of possible preoperative, operative and postoperative risk factors on the development of early postoperative pulmonary complications (POPC) after UAS. Methods: A prospective study of 60 consecutive patients was conducted who underwent elective UAS in general surgical unit. Each patient's preoperative respiratory status was assessed by an experienced chest physician using clinical examination, chest radiographs, spirometry and blood gas analysis . Anaesthetical risks, surgical indications, operation time, incision type, duration of nasogastric catheter and mobilization time were noted. Forty-eight hours after the operation, pulmonary examinations of the patients were repeated. Results: Postoperative pulmonary complications were observed in 35 patients (58.3%). The most common complication was pneumonia, followed by pneumonitis, atelectasis, bronchitis, pulmonary emboli and acute respiratory failure. The presence of preoperative respiratory symptoms and the spirometric parameter of forced expiratory volume in 1 s/forced vital capacity were the most valuable risk factors for early prediction of POPC. The sensitivity, specificity and diagnostic efficiency of the presence of preoperative respiratory symptoms in the POPC prediction were 70, 61 and 66%, respectively. Conclusion: We recommend a detailed pulmonary examination and spirometry in patients who will undergo UAS by chest physicians to identify the patients at high risk for POPC, to manage respiratory problems of the patients before surgery and also to help surgeons to take early measures in such patients before a most likely POPC occurrence. Improvement of lung function in those patients at risk for POPC before operation may decrease morbidity in surgical patients.

Rogers DVM, DACVECC Abstract Objective , To describe a severe case of bacterial sepsis and disseminated candidiasis in a previously healthy dog. Case Summary , Fungal sepsis was identified in a 2-year-old dog following intestinal dehiscence 4 days after abdominal surgery. Septic peritonitis was identified at admission and evidence of dehiscence at the previous enterotomy site was found during an exploratory laparotomy. Both gram-positive cocci and Candida albicans were cultured from the abdominal cavity. Candida sp. was also subsequently cultured from a central venous catheter. Euthanasia was performed due to failure to respond to therapy. Fungal organisms, morphologically consistent with Candida spp., were found in the lungs and kidney on postmortem histopathologic examination indicating disseminated candidiasis. New or Unique Information Provided , Candida peritonitis is a well-recognized entity in humans and contributes to morbidity and mortality in critically ill patients. Abdominal surgery, intestinal perforation, presence of central venous catheters, and administration of broad-spectrum antibiotics are all considered to be suspected risk factors. This report describes the first known case of systemic candidiasis occurring secondary to Candida peritonitis and bacterial sepsis in a critically ill dog. [source] Indigenous and austere technique of self-retaining abdominal retraction for facilitating surgical exposureJOURNAL OF SURGICAL ONCOLOGY, Issue 5 2006Sajid S. Qureshi MS Abstract Adequate exposure is of paramount importance in major abdominal surgeries. This is achieved by appropriately placed incision, proper position of the patients, and judicious use of retractors. A third assistant is usually required for retaining the retractors. Self-retaining retractors have also been utilized for assisting in adequate exposure of the operative field. However, these retractors are complex and unwieldy, causing hindrance in the movement of the surgeon. We describe a technique of self-retaining abdominal retraction that is simple and also obviates the need for an additional assistant. J. Surg. Oncol. 2006;93:420,421. © 2006 Wiley-Liss, Inc. [source] Single-port laparoscopic splenectomy: The first three casesASIAN JOURNAL OF ENDOSCOPIC SURGERY, Issue 1 2010Y.K. You Abstract In the past two decades, laparoscopic surgery has replaced open surgery in most abdominal surgeries, including splenectomies for which it has become the standard. Single-port laparoscopic surgery is a newly emerging surgical technique that decreases postoperative scarring and parietal trauma. Herein we report on three cases of splenectomy in which single-port laparoscopic surgery technique was applied. Between October 2008 and January 2009, a 13-year-old male suffering from grade-III splenic trauma and two females, aged 33 and 61, respectively, and both diagnosed with immune thrombocytopenic purpura, underwent single-port laparoscopic splenectomies. Preoperative and postoperative management, including vaccination, was performed in a routine manner. A 3.5 cm transverse incision at the anterior axillary line at umbilicus level was used as a single-port entry point. The entire procedure took 195, 125 and 133 minutes, respectively. All patients recovered and were discharged without any complications. [source] Consequences of vancomycin-resistant Enterococcus in liver transplant recipients: a matched control studyCLINICAL TRANSPLANTATION, Issue 6 2005Michelle Gearhart Abstract:, Background:, Liver transplant recipients are at high risk for multi-drug resistant infections because of broad-spectrum antibiotic and immunosuppression. This study evaluates the clinical and financial impact of vancomycin resistant Enterococcus (VRE) in liver transplant recipients. Methods:, Liver transplant recipients with VRE from 1995 to 2002 were identified and matched (age, gender, UNOS status, liver disease and transplant date) to controls. Demographics, clinical factors, co-infections, antibiotic use, length of stay, abdominal surgeries, biliary complications, survival and resource utilization were compared with matched controls. Results:, Nineteen patients were found to have 28 VRE infections via evaluation of microbiologic culture results of all liver transplant patients in the transplant registry. Thirty-eight non-VRE patients served as matched controls. The four most common sites VRE was cultured from included blood (35%), peritoneal fluid (35%), bile (20%), and urine (12%). Median time from transplant to infection was 48 d (range of 4,348). No significant differences in demographics were observed. The VRE group had a higher incidence of prior antibiotic use than the non-VRE group (95% vs. 34%; p < 0.05). The VRE group also experienced more abdominal surgery (20/19 vs. 3/38; p = 0.029), biliary complications (9/19 vs. 9/38; p = 0.018) and a longer length of stay (42.5 vs. 21.7 d; p = .005). Survival in the VRE group was lower (52% vs. 82%; p = 0.048). Six of the 19 VRE patients were treated with linezolid for eight infection episodes, and four of six patients survived. Eight patients were treated with quinupristin/dalfopristin for nine infections, and two of eight survived. Increased cost of care was observed in the VRE group. Laboratory costs were higher in the VRE group ($6500 vs. 1750; p = 0.02) as well. Conclusion:, VRE was associated with prior antibiotic use, multiple abdominal surgeries, biliary complications and resulted in decreased survival compared to non-VRE control patients. VRE patients also utilized more hospital resources. Linezolid showed a trend toward improved survival.

Transthoracic and transesophageal echocardiography documented severe tricuspid stenosis and regurgitation. The two discs of the tricuspid prosthesis were immobilized, half open and half closed. The prosthesis was replaced and the patient did well. [source] Use of web-based data collection to evaluate analgesic administration and the decision for surgery in horses with colicEQUINE VETERINARY JOURNAL, Issue 4 2005N. A. WHITE Summary Reasons for performing study: There is no current veterinary information with regard to data entry on a website. We therefore completed a prospective study on use of analgesics in relation to the need for abdominal surgery using a web-based survey instrument. Objectives: To establish an internet-based data entry system that could be used to record prospective data on horses with colic. Hypothesis: Failure of horses to respond to the initial administration of an analgesic is an indicator of the need for abdominal surgery. Methods: A survey was developed to determine if the response to administration of an analgesic during a veterinarian's first examination of a horse with colic was related to the need for surgery. Veterinarians were contacted via AAEP and ECN listservs requesting submission of cases using a log-in system at a data entry website. The survey was completed by submission of a data entry page. Results: Twenty-seven veterinarians submitted details of 119 cases of colic, 28 of which required surgery. The need for surgery was significantly associated with moderate or severe pain observed during the first examination compared to mild or no pain, and with constant pain or return of pain after administration of one or more analgesics and the need to administer a second analgesic treatment. Abnormal findings on rectal examination were not associated with the need for surgery, whereas total absence or decrease of intestinal sounds was significantly related to the odds that surgery was needed. The web-based data collection was successful in collecting all data points on the survey for each case. Conclusions: This study reinforced veterinarians' use of response to therapy as a way to determine the need for abdominal surgery. Potential relevance: When a specific diagnosis has not been made, lack of response or resumption of colic after analgesic administration should be considered as an indicator of the need for surgery. Web-based collection of data allows veterinary practitioners to participate in clinical research by providing prospective data. [source] Heightened levels of circulating 20S proteasome in critically ill patientsEUROPEAN JOURNAL OF CLINICAL INVESTIGATION, Issue 6 2005G. A. Roth Abstract Background, Recently, circulating proteasome core particles (20S proteasome) have been suggested as a marker of cell damage and immunological activity in autoimmune diseases. Aberrant leucocyte activation and increased lymphocyte apoptosis with consecutive T-cell unresponsiveness is deemed to play a pivotal role in the sepsis syndrome. Moreover sepsis-induced muscle proteolysis mainly reflects ubiqutin proteasome-dependent protein degradation. We therefore sought to investigate serum levels of 20S proteasome in critical ill patients. Material and methods, Case,control-study at a university hospital intensive care unit; 15 patients recruited within 24,48 h of diagnosis of sepsis, 13 trauma patients recruited within 24 h of admission to the ICU, a control group of 15 patients who underwent abdominal surgery, and 15 healthy volunteers. ELISA was used to measure the concentration of 20S proteasome in the sera of the patients and controls. Data are given as mean ± SEM. Mann,Whitney U -test was used to calculate significance and a P -value of 0·05 was considered to be statistically significant. Results, Marked increase of 20S proteasome was detected in the sera of septic patients (33 551 ± 10 034 ng mL,1) as well as in trauma patients (29 669 ± 5750 ng mL,1). In contrast, significantly lower concentrations were found in the abdominal surgery group (4661 ± 1767 ng mL,1) and in the healthy control population (2157 ± 273 ng mL,1). Conclusion, Detection of 20S proteasome may represent a novel marker of immunological activity and muscle degradation in sepsis and trauma patients, and may be useful in monitoring the clinical effect of proteasome-inhibitors. [source] Thrombotic complications following liver resection for colorectal metastases are preventableHPB, Issue 5 2008G. Morris-Stiff Background. Surgery for colorectal liver metastases (CRLM) can be expected to be associated with a significant rate of thromboembolic complications due to the performance of long-duration oncologic resections in patients aged 60 years. Aims. To determine the prevalence of clinically significant thrombotic complications, including deep venous thrombosis (DVT) and pulmonary embolus (PE), in a contemporary series of patients undergoing resection of CRLM with standard prophylaxis. Material and methods. A prospectively maintained database identified patients undergoing resection of CRLM from January 2000 to March 2007 and highlighted those developing thromboembolic complications. In addition, the radiology department database was reviewed to ensure that clinically suspicious thromboses had been confirmed radiologically by ultrasound in the case of DVT or computed tomography for PEs. Results. During the period of the study, 523 patients (336 M and 187 F) with a mean age of 65 years underwent resection. A major hepatectomy was performed in 59.9%. One or more complications were seen in 45.1% (n=236) of patients. Thrombotic complications were seen in 11 (2.1%) patients: DVT alone (n=4) and PE (n=7). Eight of 11 thrombotic complications occurred in patients undergoing major hepatectomy, 4 of which were trisectionectomies. Patients were anti-coagulated and there were no mortalities. Conclusions. The symptomatic thromboembolic complication rate was lower in this cohort than may be expected in patients undergoing non-hepatic abdominal surgery. It is uncertain whether this is due entirely to effective prophylaxis or to a combination of treatment and a natural anti-coagulant state following hepatic resection. [source] Laparoscopic cholecystectomy in the grossly obese: 4 years experience and review of literatureHPB, Issue 4 2002M Hussien Background Conventional abdominal surgery in grossly obese patients is associated with an increased rate of postoperative complications; thus, laparoscopic surgery may be preferred in these patients. Patients and methods A prospective analysis was performed of 20 grossly obese patients who underwent laparoscopic cholecystectomy between April 1996 and April 2000 for symptomatic non-complicated gallstone disease. Results Technical problems at operation included difficulty with induction of pneumoperitoneum and introduction of the most lateral subcostal port, retraction of the gallbladder fundus, the need for longer instruments and the closure of the fascia. Laparoscopic cholecystectomy was successfully completed in 19 patients, but one patient required conversion to open operation. There were no anaesthetic difficulties. Two patients developed minor chest infections. The mean hospital stay was 2.9 days. Conclusion Laparoscopic cholecystectomy is feasible and can be recommended for symptomatic gallstone disease in grossly obese patients. [source] NOD2/CARD15 and TNFA, but not IL1B and IL1RN, are associated with Crohn's diseaseINFLAMMATORY BOWEL DISEASES, Issue 4 2005António Carlos Ferreira BSc Abstract Background:NOD2/CARD15 was described as the first susceptibility gene to Crohn's disease (CD). Polymorphisms in the TNFA gene and in the IL1 gene cluster, which are associated with an enhanced chronic inflammatory response, may also play a role in the development of CD. The aim of this study was to determine the association of polymorphisms in the CARD15, TNFA, IL1B, and IL1RN genes with risk of development of CD and with the clinicopathological profile of CD patients. Methods: In a case-control study including 235 CD patients and 312 controls (929 controls for TNFA genotyping), the CARD15 (R702W, G908R, and1007fs), TNFA (,308G/A and ,857C/T), IL1B (,511C/T), and IL1RN (intron 2 variable number of tandem repeats) polymorphisms were genotyped. Results: We observed a significant association between CD and the CARD15 polymorphisms, with an odds ratio (OR) of 2.9 [95% confidence interval (CI), 1.9 to 4.6] for carriers of 1 variant allele and an OR of 11.8 (95% CI, 3.5 to 40.4) for carriers of 2 variant alleles. Patients with CARD15 polymorphisms had more frequently ileal or ileocolonic disease location, stricturing phenotype, abdominal surgery, and no extraintestinal manifestations. The TNFA -308A/A genotype was associated with susceptibility to CD with an OR of 3.0 (95% CI, 1.2 to 7.2). TNFA -308A/A homozygotes showed a higher frequency of erythema nodosum and arthritis, colonic disease location, and absence of abdominal surgery. No associations were found with the TNFA -857, IL1B -511, and the IL1RN VNTR polymorphisms. Conclusions: These findings suggest that CARD15 and TNFA -308 genetic polymorphisms are associated with increased risk of CD displaying distinct clinicopathological profiles. [source] Testing whether the epidural works: too time consuming?ACTA ANAESTHESIOLOGICA SCANDINAVICA, Issue 6 2010J. LARSSON Background: When using epidural anaesthesia (EDA) for pain relief after major surgery, a failure rate of 10% is common. A crucial step in improving the care of patients with EDA is to define the position of the epidural catheter. The aim of this study was to investigate how much time it takes to determine whether the block is sufficient by assessing the extent of loss of cold sensation before induction of anaesthesia. Methods: One hundred patients listed for abdominal surgery were included in the study. After an epidural catheter had been inserted and an intrathecal or an intravenous position had been made unlikely by the use of a test dose, the patient was given a bolus dose of local anaesthetic plus an opioid in the epidural catheter. The epidural block was tested every 2 min, starting at 5 min and ending at 15 min. When at least four segments were blocked bilaterally, the testing was stopped, the time was noted and the patient was anaesthetised. Results: An epidural block was demonstrated after 5,6 min in 37 patients, after 7,8 min in 43 additional patients and after 9,10 min in 15 patients. In one patient, it took 12 min and in three patients, it took 15 min. In two patients, no epidural block could be demonstrated. Conclusion: Testing an epidural anaesthetic before the induction of anaesthesia takes only 5,10 extra minutes. Knowing whether the catheter is correctly placed means better quality of care, giving the anaesthetist better prerequisites for taking care of the patient post-operatively. [source] The transversus abdominis plane block: a valuable option for postoperative analgesia?ACTA ANAESTHESIOLOGICA SCANDINAVICA, Issue 5 2010A topical review The transversus abdominis plane (TAP) block is a newly described peripheral block involving the nerves of the anterior abdominal wall. The block has been developed for post-operative pain control after gynaecologic and abdominal surgery. The initial technique described the lumbar triangle of Petit as the landmark used to access the TAP in order to facilitate the deposition of local anaesthetic solution in the neurovascular plane. Other techniques include ultrasound-guided access to the neurovascular plane via the mid-axillary line between the iliac crest and the costal margin, and a subcostal access termed the ,oblique subcostal' access. A systematic search of the literature identified a total of seven randomized clinical trials investigating the effect of TAP block on post-operative pain, including a total of 364 patients, of whom 180 received TAP blockade. The surgical procedures included large bowel resection with a midline abdominal incision, caesarean delivery via the Pfannenstiel incision, abdominal hysterectomy via a transverse lower abdominal wall incision, open appendectomy and laparoscopic cholecystectomy. Overall, the results are encouraging and most studies have demonstrated clinically significant reductions of post-operative opioid requirements and pain, as well as some effects on opioid-related side effects (sedation and post-operative nausea and vomiting). Further studies are warranted to support the findings of the primary published trials and to establish general recommendations for the use of a TAP block. [source] Functional intravascular volume deficit in patients before surgeryACTA ANAESTHESIOLOGICA SCANDINAVICA, Issue 4 2010M. BUNDGAARD-NIELSEN Background: Stroke volume (SV) maximization with a colloid infusion, referred to as individualized goal-directed therapy, improves outcome in high-risk surgery. The fraction of patients who need intravascular volume to establish a maximal SV has, however, not been evaluated, and there are only limited data on the volume required to establish a maximal SV before the start of surgery. Therefore, we estimated the occurrence and size of the potential functional intravascular volume deficit in surgical patients. Methods: Patients scheduled for mastectomy (n=20), open radical prostatectomy (n=20), or open major abdominal surgery (n=20) were anaesthetized, and before the start of surgery, a 200 ml colloid fluid challenge was provided and repeated if a ,10% increment in SV estimated by oesophageal Doppler was established. The volume needed for SV maximization defined the intravascular volume deficit. Results: Forty-two (70%) of the patients needed volume to establish a maximal SV. For the patients needing volume, the required amount was median 200 ml (range 200,600 ml), with no significant difference between the three groups of patients. The required volume was ,400 ml in nine patients (15%). Conclusion: The majority of anaesthetized patients present with a functional intravascular volume deficit before surgery. Although the deficit in general was minor, a fraction of patients presented with a deficit that may be of clinical relevance, emphasizing the importance of the individual approach of goal-directed fluid therapy. [source] Addition of nimesulide to small intestinal submucosa biomaterial inhibits postsurgical adhesiogenesis in ratsJOURNAL OF BIOMEDICAL MATERIALS RESEARCH, Issue 1 2010Mark A. Suckow Abstract Adhesion formation is a common complication in abdominal surgery with incidence as high as 93% and small bowel obstruction a common complication. Because the extracellular matrix material, small intestinal submucosa (SIS), is commonly used in various surgical procedures, methods to inhibit adhesiogenesis are of great interest. This study was undertaken to determine if incorporation of nimesulide (NM), a selective cyclooxygenase (COX)-2 inhibitor, could reduce the extent and tenacity of intraabdominal adhesion formation associated with SIS implantation. Female Sprague,Dawley rats underwent a cecal abrasion surgical procedure to induce adhesiogenesis. Rats were either left untreated or treated by direct application over the injured cecum with polypropylene mesh (PPM); SIS; SIS containing a low dose of NM; or SIS containing a high dose of NM. Rats were euthanized 21 days later, and adhesion extent and tenacity were evaluated using standard scales (0 = minimal adhesiogenesis; 4 = severe adhesiogenesis). Addition of NM to SIS resulted in a significant (p < 0.05) reduction in adhesion extent and in a similar reduction in adhesion tenacity for SIS containing a low dose of NM. Adhesions typically extended from the abraded cecal surface to the body wall and were characterized histologically by fibrous tissue adherent to the cecal wall. In conclusion, addition of the nonsteroidal anti-inflammatory, COX-2 selective drug, NM, to SIS attenuates adhesion extent and tenacity when compared with surgical placement of SIS or PPM alone. © 2010 Wiley Periodicals, Inc. J Biomed Mater Res Part B: Appl Biomater, 2010 [source] Attenuation of a rocuronium-induced neuromuscular block in patients receiving prednisoloneACTA ANAESTHESIOLOGICA SCANDINAVICA, Issue 4 2009S. SOLTÉSZ Background: This study tested the influence of continuous medication (more than 4 weeks) with prednisolone on a rocuronium-induced neuromuscular block. Methods: The time course of a rocuronium-induced neuromuscular blockade (0.3 mg/kg) was investigated in 40 patients with chronic inflammatory bowel disease undergoing elective abdominal surgery. The primary end point was the time from the start of injection of rocuronium until recovery of the TOF ratio to 0.9. Twenty patients received continuous medication with prednisolone (group A), and 20 were without glucocorticoid medication (group B). Additionally, another 20 patients without inflammatory bowel disease and without glucocorticoid medication served as control (group C). Results: The onset time was prolonged in group A [253 (51.2) s] compared with group B [187 (61.3) s]. Twitch height at the onset of the block was higher in group A [16.5 (0,61)%] than that in group B [5.0 (0,33)%]. The duration to 25% twitch height was shorter in group A [12.6 (0,20.7) min] compared with group B [16.7 (0,25.3) min] and group C [16.9 (0,29.3) min]. The recovery to a train-of-four ratio of 0.9 was reduced in group A [25.7 (23,34.3) min] compared with group B [34.7 (32.7,44.2) min] and group C [36.5 (31.7,42.3) min]. Conclusions: Prednisolone treatment in patients with inflammatory bowel disease is associated with a delayed onset and a shorter duration of action of rocuronium. The presence of an inflammatory bowel disease did not influence the neuromuscular block. [source] Epidemiology of gallstone disease in Chandigarh: A community-based studyJOURNAL OF GASTROENTEROLOGY AND HEPATOLOGY, Issue 5 2001Virendra Singh Abstract Background: Cholelithiasis is frequent in our country (India), and is a common cause for abdominal surgery. We studied the prevalence of gallstone disease and its association with various risk factors in the city of Chandigarh. Methods: A house-to-house survey of residents aged 15 years or above in a subsector of Chandigarh was conducted as a part of a pilot survey. All individuals with a history of gallstone disease, and equal or more number of asymptomatic individuals were asked to attend the outpatient department of the Postgraduate Medical Institute. On the basis of the pilot survey, the sample size to be studied was 2648 and we screened 2649 persons. Results: Two hundred and fifty-four individuals attended the outpatient services of the Institute, and 248 underwent an ultrasound. There were 37 symptomatic and 211 asymptomatic individuals (male : female, 93:155). Gallstone disease was seen in 24 out of 37 (64.9%) in the symptomatic, and seven out of 211 (3.3%) in the asymptomatic group. Out of these, 27 females and four males had gallstone disease (mean age: 48.30 ± 16.03 years). Approximately 67% of patients were between 20 and 60 years of age. Gallstone disease was more frequently seen in those from high socioeconomic status as compared to middle socioeconomic status (,2 = 8.9, d.f. = 1, P < 0.01), and in multiparous as compared to nulliparous females (,2 = 4.8, d.f. = 1, P < 0.05). Body mass index, smoking, alcohol consumption, and a vegetarian/non-vegetarian diet did not influence the prevalence of gallstone disease. Conclusions: Gallstone disease is frequent in northern India. Gallstones were frequent in those belonging to high socioeconomic status and multiparous females. However, body mass index, smoking, alcohol or other dietary habits did not make a difference. [source] Clinical pitfalls of pain recurrence in endometriosis arising in the posterior vaginal fornixJOURNAL OF OBSTETRICS AND GYNAECOLOGY RESEARCH (ELECTRONIC), Issue 2 2007Masahito Tachibana Abstract Endometriotic nodules in the lower genital tract often cause dysmenorrhea and dyspareunia. We report here a case of posterior vaginal fornix endometriosis that was overlooked for several years. We performed a trans -vaginal resection after the associated pain was not relieved by repetitive gonadotropin-releasing hormone agonist (GnRHa) therapy or abdominal surgery. After the resection, the patient's symptoms disappeared. The patient subsequently conceived and proceeded to a full-term delivery. The pathological diagnosis was ,endometriosis of the vagina.' Immunohistochemical staining revealed that the progesterone receptor-positive cells outnumbered the estrogen receptor-positive cells. We emphasize that the existence of vaginal lesions should be considered in cases in which pain has not improved despite long-term GnRHa administration, or in cases involving dyspareunia. To provide appropriate treatment, attentive evaluation and careful examination of the disease are necessary for a patient with prolonged unsatisfactory progress. [source] Hansenula anomala infection in a neonateJOURNAL OF PAEDIATRICS AND CHILD HEALTH, Issue 6 2000A R Wong Abstract: We present an unusual neonatal fungal infection, Hansenula anomala in a very low birthweight infant who underwent abdominal surgery for an omphalocele. Despite treatment with adequate doses of amphotericin B, the yeast continued to grow from the blood culture, and was only eradicated with the use of oral ketoconazole. [source] Continuous intravenous lidocaine in the treatment of paralytic ileus due to severe spinal cord injuryACTA ANAESTHESIOLOGICA SCANDINAVICA, Issue 1 2009A. BAUMANN Paralytic ileus is a major concern in the acute phase of spinal cord injury. Classical treatment with neostigmine is often ineffective. Continuous intravenous (i.v.) lidocaine infusion has been previously proposed intra and post-operatively in order to decrease the duration of post-operative ileus after abdominal surgery. We report the cases of seven patients suffering from complete paralytic spinal cord injury-related ileus with colectasy resistant to neostigmine, who were treated by i.v. lidocaine infusion. [source] Blood volume is normal after pre-operative overnight fastingACTA ANAESTHESIOLOGICA SCANDINAVICA, Issue 4 2008M. JACOB Background: Pre-operative fasting is assumed to cause a deficit in intravascular blood volume (BV), as a result of ongoing urine production and insensible perspiration. Standard regimes consist of volume loading prior or simultaneous to any anaesthetic procedure to minimise the risk of hypotension. However, fluid overload in the context of major abdominal surgery has been shown to deteriorate patient outcome. Our study aimed to quantify total intravascular BV after fasting by direct measurements and to compare it with calculated normal values in comparable non-fasted patients. Methods: After 10 h of fasting, total plasma volume (PV) and red cell volume (RCV) were measured via the double-label technique (indocyanine green dilution and erythrocytes labelled with fluorescein, respectively) following induction of general anaesthesia in 53 gynaecological patients suffering from malignoma of the cervix. The corresponding normal values were calculated individually from age, body height and body weight. Results: Measured BV, RCV and PV after fasting were 4123±589, 1244±196 and 2879±496 ml, respectively. The differences to the corresponding calculated normal values were not significant (3882±366, 1474±134 and 2413±232 ml, respectively). The measured haematocrit reflected a slight anaemic state (0.35±0.03). Conclusion: Our data suggest that even after prolonged pre-operative fasting, cardio-pulmonary healthy patients remain intravascularly normovolaemic. Therefore, hypotension associated with induction of general or neuraxial anaesthesia should perhaps be treated with moderate doses of vasopressors rather than with undifferentiated volume loading. [source] Increased Cortisol Response to Surgery in Patients With Alcohol Problems Who Developed Postoperative ConfusionALCOHOLISM, Issue 8 2004Akira Kudoh Background: Patients with alcohol problems often develop postoperative confusion and have impaired cortisol, ACTH, and norepinephrine. However, the relationship between neuroendocrine responses to surgical stress and postoperative confusion remains unclear in patients with alcohol problems. Methods: Plasma cortisol, ACTH, and norepinephrine concentrations during and after surgery in 30 patients with alcohol problems and 30 control patients who underwent lower abdominal surgery were measured before the induction of anesthesia, 15 and 60 min after skin incision, 60 min after the end of surgery, the next day, and the second day after the operation. Results: Plasma cortisol concentrations (21.2 ± 4.7 ,g·dl,1) of patients with alcohol problems before anesthesia were significantly higher than 15.6 ± 4.8 ,g·dl,1 of control patients. Plasma cortisol and ACTH responses to surgery in patients with alcohol problems were not significantly increased compared with preoperative values. The incidence of postoperative confusion was significantly higher in patients with alcohol problems than that of control patients (33% vs. 3%). Plasma cortisol concentrations (29.7 ± 7.0, 31.2 ± 6.6, 30.3 ± 8.0, and 28.4 ± 6.2 ,g·dl,1) 15 and 60 min after the skin incision, 60 min after the end of surgery, and the next day after operation in postoperatively confused patients with alcohol problems were significantly higher than those of nonconfused patients with alcohol problems (23.0 ± 5.8, 22.7 ± 4.1, 22.4 ± 7.2, and 21.9 ± 5.5 ,g·dl,1). Conclusion: The cortisol response to surgical stress increases in patients with alcohol problems who develop postoperative confusion, although cortisol response to surgical stress decreases in patients with alcohol problems without postoperative confusion.

However it is difficult to perform HAIC in the long term without complications. This report describes the laparotomic approach using the side holed catheter, which is a novel method of implanting a catheter-port system. Methods and Results We designed a new anti-thrombotic catheter for HAIC. This catheter is tapered from 5F (diameter of shaft) to 3.3F (diameter at tip), and a side hole is opened 7 cm from the tip of catheter. This catheter is inserted from the gastroduodenal artery to the common hepatic artery (CHA), and the tip is put in the aorta or in the splenic artery. The side hole is adjusted distal to the CHA. In our surgical department, our new catheter was inserted in four patients at the time of their abdominal surgery. The cannulation was performed successfully in all patients. In two of them, HAIC was finished without problems at 6 months after starting, and two were still treated by HAIC at 9 and 8 months after starting. Conclusions Initial results from a study of a new method of implanting a catheter-port system in the hepatic artery using the new tapering side hole catheter suggest that this method may enable operators to avoid complicated selective coiling and may lower the incidence of hepatic artery occlusion in patients receiving long-term HAIC.

[source] Arterial oxygen tension increase 2,3 h after hyperbaric oxygen therapy: a prospective observational studyACTA ANAESTHESIOLOGICA SCANDINAVICA, Issue 1 2007B. Ratzenhofer-Komenda Background:, Inhalation of hyperbaric oxygen (HBO) has been reported to decrease arterial oxygen tension (PaO2) in the early period after exposure. The current investigation aimed at evaluating whether and to what extent arterial blood gases were affected in mechanically ventilated intensive care patients within 6 h after HBO treatment. Methods:, Arterial blood gases were measured in 11 ventilated subjects [nine males, two females, synchronized intermittent mandatory ventilation (SIMV) mode] undergoing HBO therapy for necrotizing soft tissue infection (seven patients), burn injury (two patients), crush injury (one patient) and major abdominal surgery (one patient). Blood gases were obtained with the patients in the supine position under continuous analgesia and sedation before the hyperbaric session (baseline), during isopression, after decompression, after each transport, and 1, 2, 3 and 6 h after exposure. Heart rates and blood pressures were recorded. Intensive care unit (ICU) ventilator settings remained unchanged. Transport and chamber ventilator settings were adjusted to baseline with maintenance of tidal volumes and positive end-expiratory pressure (PEEP) levels. The hyperbaric protocol consisted of 222.9 kPa (2.2 absolute atmospheres) and a 50-min isopression phase. The paired Wilcoxon's test was used. Results:, Major findings (median values, 25%/75% quantiles) as per cent change of baseline: PaO2 values decreased by 19.7% (7.0/31.7, P < 0.01) after 1 h and were elevated over baseline by 9.3% (1.5/13.7, P < 0.05) after 3 h. SaO2, alveolar-arterial oxygen tension difference and PaO2/FiO2 ratio behaved concomitantly. Acid-base status and carbon dioxide tension were unaffected. Conclusion:, Arterial oxygen tension declines transiently after HBO and subsequently improves over baseline in intensive care patients on volume-controlled mechanical ventilation. The effectiveness of other ventilation modes or a standardized recruitment manoeuvre has yet to be evaluated. [source] Clinical trial: the impact of cyclooxygenase inhibitors on gastrointestinal recovery after major surgery , a randomized double blind controlled trial of celecoxib or diclofenac vs. placeboALIMENTARY PHARMACOLOGY & THERAPEUTICS, Issue 10 2009D. A. WATTCHOW Summary Background, Ileus occurs after abdominal surgery and may be severe. Inhibition of prostaglandin release reduces post-operative ileus in a rat model. Aim, To determine whether prostaglandin inhibition by cyclooxygenase inhibitors, celecoxib or diclofenac, could enhance gastrointestinal recovery and reduce post-operative ileus in humans. Methods, Two hundred and ten patients undergoing elective major abdominal surgery were randomized to receive twice daily placebo (n = 67), celecoxib (100 mg, n = 74) or diclofenac (50 mg, n = 69), preoperatively and continuing for up to 7 days. Primary outcomes were hallmarks of gut recovery. Secondary outcomes were paralytic ileus, pain and complications. Results, There was no clinically significant difference between the groups for restoration of bowel function. There was a significant reduction in paralytic ileus in the celecoxib-treated group (n = 1, 1%) compared with diclofenac (n = 7, 10%) and placebo (n = 9, 13%); P = 0.025, RR 0.20, CI 0.01,0.77. Pain scores, analgesia, transfusion requirements and adverse event rates were similar between study groups. Conclusions, Perioperative low dose celecoxib, but not diclofenac, markedly reduced the development of paralytic ileus following major abdominal surgery, but did not accelerate early recovery of bowel function. This was independent of narcotic use and had no increase in post-operative complications. [source] Incidence of venous thromboembolism following major abdominal surgery: a multi-center, prospective epidemiological study in JapanJOURNAL OF THROMBOSIS AND HAEMOSTASIS, Issue 3 2006M. SAKON Summary.,Background:,Venous thromboembolism (VTE) has been considered to be a rare surgical complication in Japan. Aim:,To investigate the incidence and risk factors of VTE in Japanese patients undergoing major abdominal surgery. Methods:,A prospective, multi-center epidemiological study was conducted from December, 2001 to August 2002 in 39 medical institutes throughout Japan. A total of 173 patients with general (n = 128), gynecologic (n = 23), and urologic (n = 22) surgery were analyzed. For the diagnosis of deep vein thrombosis (DVT), bilateral venography was performed in all patients. Lung ventilation/perfusion scintigraphy was carried out in patients suspected of pulmonary thromboembolism (PTE). Results:,There were 36 patients with distal DVT (20.8%) and five patients with proximal DVT (2.9%). One patient was diagnosed as PTE. Overall, VTE was diagnosed in 42 patients (24.3%). By univariate analysis, only age (60 years or older) was identified as a significant risk factor in the whole study population. When analyzed by the stepwise multiple logistic regression model, female gender, operation site, age, and operation time were four risk factors found to be significant. The incidence of VTE was closely related to the number of risk factors that patients had. As many as 44% of patients with three or four risk factors developed VTE while those with one or two risk factors showed about a 17% incidence of VTE. Four patients lacking any risk factors did not develop VTE. Conclusions:,Venous thromboembolism is common in Japanese patients undergoing major abdominal surgery. Pharmacologic thromboprophylaxis is considered essential, particularly in those patients with multiple, potential risk factors.

Langdon Fielding DVM, DACVECC Abstract Objective , To describe the clinical and clinicopathologic abnormalities in endurance horses eliminated from competition and requiring emergency medical treatment. Design , Retrospective study over a 2-year period (2005,2006). Ten horses that successfully completed the ride in 2006 were included for comparison. Setting , Temporary equine emergency field hospital. Animals , All horses (n=30) that were removed from endurance competition and treated for a metabolic abnormality were studied. Interventions , Horses were treated with IV fluids and analgesics. Monitoring included lab work (PCV, total protein, and electrolytes) and serial physical examinations. Statistical analysis included descriptive statistics and parametric and nonparametric comparisons (ANOVA, Friedman's test, and Kruskal-Wallis) where appropriate. Measurements and Main Results , The clinical diagnoses identified included colic, esophageal obstruction, poor cardiovascular recovery, myopathy, and synchronous diaphragmatic flutter. As a group, these sick horses had lower plasma chloride and potassium and higher total plasma protein concentrations as compared with 10 healthy horses that successfully completed the ride (P<0.05, <0.01, and <0.05 for chloride, potassium, and total protein, respectively). Horses with colic had a lower PCV as compared with horses with poor recovery and those with synchronous diaphragmatic flutter (P<0.05). All horses, including colics, were treated medically and discharged to owners. Conclusions , Based on the results of this study, the prognosis for horses requiring emergency veterinary treatment after being removed from endurance competition (for metabolic reasons) appears to be good if horses are withdrawn from competition under the same criteria outlined in this study. Biochemical abnormalities tend to be mild and do not necessarily aid in delineating sick horses from successfully completing horses. None of the horses with gastrointestinal disease required abdominal surgery. [source] Disseminated candidiasis secondary to fungal and bacterial peritonitis in a young dogJOURNAL OF VETERINARY EMERGENCY AND CRITICAL CARE, Issue 2 2009Catherine L. Rogers DVM, DACVECC Abstract Objective , To describe a severe case of bacterial sepsis and disseminated candidiasis in a previously healthy dog. Case Summary , Fungal sepsis was identified in a 2-year-old dog following intestinal dehiscence 4 days after abdominal surgery. Septic peritonitis was identified at admission and evidence of dehiscence at the previous enterotomy site was found during an exploratory laparotomy. Both gram-positive cocci and Candida albicans were cultured from the abdominal cavity. Candida sp. was also subsequently cultured from a central venous catheter. Euthanasia was performed due to failure to respond to therapy. Fungal organisms, morphologically consistent with Candida spp., were found in the lungs and kidney on postmortem histopathologic examination indicating disseminated candidiasis. New or Unique Information Provided , Candida peritonitis is a well-recognized entity in humans and contributes to morbidity and mortality in critically ill patients. Abdominal surgery, intestinal perforation, presence of central venous catheters, and administration of broad-spectrum antibiotics are all considered to be suspected risk factors. This report describes the first known case of systemic candidiasis occurring secondary to Candida peritonitis and bacterial sepsis in a critically ill dog.
