Surgical Morbidity (surgical + morbidity)
Selected AbstractsEarly Surgical Morbidity and Mortality in Adults with Congenital Heart Disease: The University of Michigan ExperienceCONGENITAL HEART DISEASE, Issue 2 2008Ginnie L. Abarbanell MD ABSTRACT Objectives., To review early surgical outcomes in a contemporary series of adults with congenital heart disease (CHD) undergoing cardiac operations at the University of Michigan, and to investigate possible preoperative and intraoperative risk factors for morbidity and mortality. Methods., A retrospective medical record review was performed for all patients ,18 years of age who underwent open heart operations by a pediatric cardiothoracic surgeon at the University of Michigan Congenital Heart Center between January 1, 1998 and December 31, 2004. Records from a cohort of pediatric patients ages 1,17 years were matched to a subset of the adult patients by surgical procedure and date of operation. Results., In total, 243 cardiac surgical operations were performed in 234 adult patients with CHD. Overall mortality was 4.7% (11/234). The incidence of major postoperative complications was 10% (23/234) with a 19% (45/23) minor complication rate. The most common postoperative complication was atrial arrhythmias in 10.8% (25/234). The presence of preoperative lung or liver disease, prolonged cardiopulmonary bypass and aortic cross clamp times, and postoperative elevated inotropic score and serum lactates were significant predictors of mortality in adults. There was no difference between the adult and pediatric cohorts in terms of mortality and morbidity. Conclusions., The postoperative course in adults following surgery for CHD is generally uncomplicated and early survival should be expected. Certain risk factors for increased mortality in this patient population may include preoperative presence of chronic lung or liver dysfunction, prolonged cardiopulmonary bypass and aortic cross-clamp times, and postoperative elevated inotropic score and serum lactate levels.

Biertho Background: Surgical morbidity and mortality rates are increased in elderly patients. The aim of this study was to evaluate the outcome of targeted parathyroid operations in patients over the age of 70 years. Methods: Forty patients aged over 70 years underwent targeted parathyroidectomy for primary hyperparathyroidism (HPT). Data were collected prospectively and reviewed retrospectively. Results: There were 33 women and seven men with a mean age of 78 (range 70,92) years, all of whom had symptoms attributable to HPT. A solitary parathyroid adenoma was detected by ultrasonography and/or sestamibi scintigraphy before operation in all patients. Six patients had a history of neck surgery, including two with persistent or recurrent HPT. Thirty-three patients underwent neck exploration under local anaesthesia with intravenous sedation. Following parathyroidectomy, intraoperative parathyroid hormone levels normalized in 39 of 40 patients and accurately predicted postoperative eucalcaemia. Intraoperative findings included 37 solitary adenomas, one double adenoma and two carcinomas. One patient with persistent HPT developed severe hypoparathyroidism following targeted parathyroid exploration with autotransplantation. Twenty-nine patients were discharged from hospital on the day of surgery. Nineteen of 21 patients for whom data were available reported an improvement in symptoms. Conclusion: A focused neck exploration provides a safe and effective alternative to bilateral neck exploration in elderly patients in whom a solitary parathyroid adenoma has been localized before operation. Targeted parathyroidectomy under local anaesthesia is recommended in most elderly patients with HPT. Copyright © 2003 British Journal of Surgery Society Ltd. Published by John Wiley & Sons, Ltd. [source] Treatment of the N0 neck during salvage surgery after radiotherapy of head and neck squamous cell carcinomaHEAD & NECK: JOURNAL FOR THE SCIENCES & SPECIALTIES OF THE HEAD AND NECK, Issue 8 2005Stephane Temam MD Abstract Background. The morbidity and mortality rates of salvage surgery in patients with local recurrence of head and neck squamous cell carcinoma (HNSCC) after radiotherapy are high. The aim of this study was to determine the rate of occult neck node metastasis and the surgical morbidity of patients after salvage surgery for local relapse after definitive radiotherapy. Methods. Thirty patients who underwent salvage surgery with a simultaneous neck node dissection for a local relapse after definitive radiotherapy for HNSCC between 1992 and 2000 were included in this study. The primary tumor sites were oral cavity in six patients, oropharynx in 17, supraglottic larynx in three, and hypopharynx in four. Initially, seven patients had T2 disease, eight had T3, and 15 had T4. Results. Twelve patients (40%) experienced postoperative complications, including two deaths. There was no cervical lymph node metastasis (pN0) in 29 of the 30 patients. Fifteen patients (50%) had a recurrence after salvage surgery, including 11 new local recurrences and four patients with distant metastasis. Conclusions. The risk of neck node metastasis during salvage surgery for local recurrence in patients treated initially with radiation for N0 HNSCC is low. Neck dissection should be performed in only limited area, depending on the surgical procedure used for tumor resection. © 2005 Wiley Periodicals, Inc. Head Neck27: XXX,XXX, 2005 [source] Comparison of transperitoneal and retroperitoneal laparoscopic nephrectomy for renal cell carcinoma: A single-center experience of 100 casesINTERNATIONAL JOURNAL OF UROLOGY, Issue 11 2008Takatsugu Okegawa Objectives: To report our experience with the retroperitoneal and transperitoneal approaches of laparoscopic nephrectomy for renal cell carcinoma (RCC). Methods: Between July 2001 and December 2007, 100 patients with RCC underwent laparoscopic radical nephrectomy at our institution for clinically localized RCC. Fifty-three patients received a retroperitoneal procedure and 47 received a transperitoneal procedure. The perioperative and oncological outcomes of these groups were reviewed retrospectively. Results: Mean follow up was 34 months. No statistically significant difference was found between the two approaches in terms of pathological stage, operative time, need for additional procedures such as adrenalectomy and/or lymph node sampling, estimated blood loss, need for blood transfusions, analgesic requirement, length of hospital stay, or the incidence of minor or major complications. The 5-year disease-free survival rate was 90% for both the retroperitoneal and transperitoneal procedures. The 5-year overall survival rates were 98% and 96%, respectively. Therefore, no significant difference was observed in the long-term oncological outcome between the two groups. Conclusions: Tumor control and surgical morbidity in laparoscopic radical nephrectomy seem not to be significantly influenced by the approach. [source] Uterine artery occlusion and myomectomy for treatment of pregnant women with uterine leiomyomas who are undergoing cesarean sectionJOURNAL OF OBSTETRICS AND GYNAECOLOGY RESEARCH (ELECTRONIC), Issue 2 2010Jui-Yu Lin Abstract Aim:, To evaluate the efficacy of uterine artery occlusion and myomectomy (UAO+M) for pregnant women with uterine leiomyomas who are undergoing cesarean section (CS). Methods:, Seventy-two women with uterine leiomyomas undergoing CS for obstetrical reasons were enrolled into this case,control study. Thirty-six patients underwent UAO+M during CS (UAO+M group), and 36 received CS alone (Control group). The UAO+M procedure was performed immediately after closure of the uterine incision wound. The outcome was measured by comparing surgical techniques, and future surgical intervention (myomectomy, uterine vessel occlusion or hysterectomy) for symptomatic leiomyoma. Results:, The average follow-up time was 63 months. General characteristics of the patients were similar in both groups. There were no statistical differences in intraoperative blood loss, postoperative recovery, complications, or wound pain between the two groups. The operative time was significantly longer in the UAO+M group compared with that in the Control group, but the further surgical intervention rate was significantly lower in the UAO+M group than in the Control group (2.8% vs 41.7%, P < 0.001). Seven patients (19%) in the UAO+M group and five (14%) in the Control group had a repeat CS during the follow-up period. Conclusion:, UAO+M could be considered for treating pregnant women with uterine leiomyomas who are undergoing CS, compared with observation, as this procedure can minimize the necessity for future surgery, with increased operative time for the UAO+M procedure, but without increased surgical morbidity. [source] Endoscopic Transnasal Craniotomy and the Resection of Craniopharyngioma,THE LARYNGOSCOPE, Issue 7 2008Aldo C. Stamm MD Abstract Objectives/Hypothesis: To describe the utility of a large transnasal craniotomy and its reconstruction in the surgical management of patients with craniopharyngioma. Study Design: Observational retrospective cohort study. Methods: Retrospective review of patients treated in an academic neurosurgery/rhinology practice between 2000 and 2007. Patient characteristics (age, sex, follow-up), tumor factors (size, position extension, previous surgery), type of repair (pedicled mucosal flaps, free mucosal grafts), and outcomes (visual, endocrine, and surgical morbidity) were defined and sought in patients who had an entirely endoscopic resection of extensive craniopharyngioma (defined as requiring removal of the planum sphenoidale in addition to sella exposure in the approach). Results: Seven patients had an entirely endoscopic resection of extensive craniopharyngioma during the study period. Mean age was 23.4 years (standard deviation ± 16.3). Mean tumor size was 3.2 cm (standard deviation ± 2.0). The majority of these pathologies had extensive suprasellar disease, and two (28.6%) had ventricular disease. Cerebrospinal fluid leak rate was 29% (2 of 7). These leaks occurred only in reconstructions with free mucosal grafts. There were no cerebrospinal fluid leaks in patients who had vascularized pedicled septal flap repairs. Conclusions: The endoscopic management of large craniopharyngioma emphasizes recent advancements in endoscopic skull base surgery. The ability to provide exposure through a large (4 cm+) transnasal craniotomy, near-field assessment of neurovascular structures, and the successful reconstruction of a large skull defect have significantly advanced the field in the past decade. The use of a two-surgeon approach and bilateral pedicled septal mucosal flaps have greatly enhanced the reliability of this approach. [source] Auditory Brainstem Implantation in Patients with Neurofibromatosis Type 2,THE LARYNGOSCOPE, Issue 12 2004Seth J. Kanowitz MD Abstract Objectives: Multichannel auditory brainstem implants (ABI) are currently indicated for patients with neurofibromatosis type II (NF2) and schwannomas involving the internal auditory canal (IAC) or cerebellopontine angle (CPA), regardless of hearing loss (HL). The implant is usually placed in the lateral recess of the fourth ventricle at the time of tumor resection to stimulate the cochlear nucleus. This study aims to review the surgical and audiologic outcomes in 18 patients implanted by our Skull Base Surgery Team from 1994 through 2003. Study Design: A retrospective chart review of 18 patients with ABIs. Methods: We evaluated demographic data including age at implantation, number of tumor resections before implantation, tumor size, surgical approach, and postoperative surgical complications. The ABI auditory results at 1 year were then evaluated for number of functioning electrodes and channels, hours per day of use, nonauditory side effect profile and hearing results. Audiologic data including Monosyllable, Spondee, Trochee test (MTS) Word and Stress scores, Northwestern University Children's Perception of Speech (NU-CHIPS), and auditory sensitivity are reported. Results: No surgical complications caused by ABI implantation were revealed. A probe for lateral recess and cochlear nucleus localization was helpful in several patients. A range of auditory performance is reported, and two patients had no auditory perceptions. Electrode paddle migration occurred in two patients. Patient education and encouragement is very important to obtain maximum benefit. Conclusions: ABIs are safe, do not increase surgical morbidity, and allow most patients to experience improved communication as well as access to environmental sounds. Nonauditory side effects can be minimized by selecting proper stimulation patterns. The ABI continues to be an emerging field for hearing rehabilitation in patients who are deafened by NF2. [source] Retropharyngeal Lipoma Causing Obstructive Sleep Apnea: Case Report Including Five-Year Follow-Up,THE LARYNGOSCOPE, Issue 9 2002Neil G. Hockstein MD Abstract Objectives/Hypothesis Lipomas of the retropharyngeal space are rare and do not cause symptoms until they reach a large size. Although retropharyngeal lipoma is an uncommon entity, several reports of it appear in the literature, and the treatment has routinely been surgical excision. Such fatty tumors also carry the rare possibility of being liposarcomas, which further warrants their excision. We present the case of a lipoma of the retropharyngeal space extending from the nasopharynx to the superior mediastinum causing symptoms of obstructive sleep apnea. The patient had multiple medical problems and was on a regimen of anticoagulation therapy; therefore, he opted against surgical treatment. He has used continuous positive airway pressure and has been followed clinically and radiographically for 5 years. Radiographic follow-up of a retropharyngeal lipoma after a needle biopsy confirming its benign nature is a legitimate means of management of this rare condition. Study Design Case report of a 64-year-old man presenting with this rare lesion. Methods Computed tomography-guided needle biopsy of the mass was performed to obtain tissue diagnosis. Thereafter, the patient has been followed for 5 years with annual magnetic resonance imaging scans to determine growth or changes of the retropharyngeal mass. Results Fine-needle aspiration of the mass revealed mature adipose tissue intermixed with fibroconnective tissue, consistent with lipoma. Based on this result, we opted to follow this patient with serial magnetic resonance imaging scans, which have shown no change in size. There has also been no change in the patient's symptoms. Conclusions Large lipomas warrant excision, especially when their location produces pressure symptoms. However, when surgical morbidity is high, fine-needle aspiration biopsy and serial magnetic resonance imaging scans are a safe alternative. [source] Carotid redo surgery: both safe and durableANZ JOURNAL OF SURGERY, Issue 12 2003Richard A. Harris Aim: To examine the outcomes and complications of surgery for recurrent carotid stenosis. Methods: From 1974 to 2000, 1922 carotid endarterectomies were performed in our unit. A retrospective cohort analysis of these records identified 24 patients (1.2%) who underwent surgery for recurrent stenosis. Results: There were 13 men and 11 women in the group. Median follow up was 7.2 years (interquartile range 4.4,12.4 years). The indication for redo surgery was either symptomatic severe (80,99%) or moderate (50,79%) restenosis, or severe asymptomatic (80,99%) restenosis. Repair was performed by patch angioplasty (88%), endarterectomy alone (8%) or interposition grafting (4%). Within the 30 day perioperative period there were no deaths, no strokes (major or minor), or significant cardiac morbidity. One patient (4%) developed a permanent spinal accessory nerve deficit. Another patient (4%) required further re-intervention for recurrent disease. Conclusions: Very low surgical morbidity and mortality was achieved in our unit by implementing a policy of selective re-intervention for carotid restenosis. Redo carotid endarterectomy can therefore be recommended as having no greater morbidity than primary carotid endarterectomy. Carotid angioplasty and stenting are not recommended as a routine alternative treatment. [source] Acute renal failure in the surgical settingANZ JOURNAL OF SURGERY, Issue 3 2003Paul Carmichael Acute renal failure (ARF) is an unwelcome complication of major surgical procedures that contributes to surgical morbidity and mortality. Acute renal failure associated with surgery may account for 18,47% of all cases of hospital-acquired ARF. The overall incidence of ARF in surgical patients has been estimated at 1.2%, although is higher in at-risk groups. Mortality of patients with ARF remains disturbingly high, ranging from 25% to 90%, despite advances in dialysis and intensive care support. Appreciation of at-risk surgical populations coupled with intensive perioperative care has the capacity to reduce the incidence of ARF and by implication mortality. Developments in understanding the pathophysiology of ARF may eventually result in newer therapeutic strategies to either prevent or accelerate recovery from ARF. At present the best form of treatment is prevention. In this review the epidemiology, pathophysiology, diagnosis, treatment and possible prevention of ARF will be discussed. [source] Health-related quality of life assessment after breast reconstruction,BRITISH JOURNAL OF SURGERY (NOW INCLUDES EUROPEAN JOURNAL OF SURGERY), Issue 6 2009S. Potter Background: Health-related quality of life (HRQL) is an important outcome following breast reconstruction. This study evaluated current methods of HRQL assessment in patients undergoing latissimus dorsi breast reconstruction, hypothesizing that early surgical morbidity would be reflected by poorer HRQL scores. Methods: Patients completed the European Organization for Research and Treatment of Cancer (EORTC) QLQ-C30 and breast module (QLQ-BR23), the Functional Assessment of Cancer Therapy (FACT) general measure, and breast module and arm subscale (FACT-B + 4), and the Body Image Scale and Hospital Anxiety and Depression Scale (HADS) 3 months after surgery. They also reported additional HRQL problems not included in the questionnaires. HRQL scores were compared between patients with and without early surgical morbidity. Results: Sixty women completed the questionnaires, of whom 25 (42 per cent) experienced complications. All EORTC and FACT subscale and HADS scores were similar in patients with or without morbidity. Women with complications were twice as likely to report feeling less feminine and dissatisfied with the appearance of their scar than those without problems. Thirty-two women (53 per cent) complained of problems not covered by the questionnaires, most commonly donor-site morbidity. Conclusion: Existing HRQL instruments are not sufficiently sensitive to detect clinically relevant problems following breast reconstruction. Copyright © 2009 British Journal of Surgery Society Ltd. Published by John Wiley & Sons, Ltd. [source] Effect of type of resection on outcome of hepatic resection for colorectal metastases,BRITISH JOURNAL OF SURGERY (NOW INCLUDES EUROPEAN JOURNAL OF SURGERY), Issue 10 2007R. J. B. Finch Background: Non-anatomical liver resections have become more common in the management of colorectal liver metastases. This study examined survival and patterns of recurrence following surgery for colorectal liver metastases. Methods: Data were collected prospectively on all patients who had hepatic surgery for colorectal liver metastases at St James' University Hospital, Leeds between 1993 and May 2003, and analysed with respect to type of resection. Results: A total of 96 patients underwent non-anatomical liver resection, 280 patients had an anatomical resection, and 108 patients had a combined procedure. There was no significant difference in overall survival between the anatomical and non-anatomical groups (hazard ratio 1·14 (95 per cent confidence interval 0·60 to 2·17); P = 0·691). Intrahepatic recurrence was significantly less common in the anatomical group, whereas morbidity and mortality rates were lower in the non-anatomical group. On multivariable analysis, multiple metastases and poorer primary T stage predicted poorer overall survival and a positive resection margin predicted poorer disease-free survival. Conclusion: Non-anatomical resection can be performed with lower rates of surgical morbidity and mortality than anatomical resection, and does not disadvantage the patient in terms of overall survival.

[source] Improving operative safety for cirrhotic liver resectionBRITISH JOURNAL OF SURGERY (NOW INCLUDES EUROPEAN JOURNAL OF SURGERY), Issue 2 2001Dr C.-C. Background: Liver resection in a patient with cirrhosis carries increased risk. The purposes of this study were to review the results of cirrhotic liver resection in the past decade and to propose safe strategies for cirrhotic liver resection. Methods: Based on the date of operation, 359 cirrhotic liver resections in 329 patients were divided into two intervals: period 1, from September 1989 to December 1994, and period 2, from January 1995 to December 1999. The patient backgrounds, operative procedures and early postoperative results were compared between the two periods. The factors that influenced surgical morbidity were analysed. Results: In period 2, patient age was higher and the amounts of blood loss and blood transfused were lower. Although postoperative morbidity rates were similar, blood transfusion requirement, postoperative hospital stay and mortality rate were significantly reduced in period 2. No death occurred in 154 consecutive cirrhotic liver resections in the last 38 months of the study. Prothrombin activity and operative time were independent factors that influenced postoperative morbidity. Conclusion: With improving perioperative assessment and operative techniques, most complications after cirrhotic liver resection can be treated with a low mortality rate. However, more care should be taken if prothrombin activity is low or there is a long operating time. © 2001 British Journal of Surgery Society Ltd [source] Phase II trial of neoadjuvant docetaxel and gefitinib followed by radical prostatectomy in patients with high-risk, locally advanced prostate cancerCANCER, Issue 4 2009Jacqueline Vuky MD Abstract BACKGROUND: Prostate cancer trials investigating neoadjuvant hormonal therapy, followed by surgery, have demonstrated that elimination of all tumor cells from the primary site is rare. The authors report a phase 2 trial assessing the efficacy and toxicity of docetaxel and gefitinib in patients with high-risk localized prostate cancer as neoadjuvant therapy before radical prostatectomy (RP). METHODS: Thirty-one patients with high-risk prostate cancer were treated with docetaxel and gefitinib for 2 months before RP. All patients met the criteria of clinical stage T2b-3 or serum prostate-specific antigen (PSA) level >20 ng/mL, or Gleason score of 8 to 10. The primary endpoint was pathologic complete response. Secondary objectives included clinical response. When available, endorectal coil magnetic resonance imaging (eMRI) was performed as part of clinical response evaluation. Immunohistochemical staining of epidermal growth factor receptor and HER-2/neu was performed on prechemotherapy and postchemotherapy prostate tissue. RESULTS: The median age of the patients was 60 years, the median pretreatment PSA level was 7.43 ng/mL, and the median Gleason score was 8. Clinical staging prior to treatment consisted of: T1 in 4 patients, T2 in 17 patients, and T3 in 10 patients. One patient with enlarged pelvic adenopathy and T4 disease did not undergo RP. Thirty patients received all scheduled therapies including RP. Grade 3 toxicities included asymptomatic liver function test elevation in 4 (13%) patients, diarrhea in 1 (3%) patient, and fatigue in 1 (3%) patient. One patient experienced grade 4 toxicity with elevated alanine aminotransferase. RP specimen pathology demonstrated residual carcinoma in all cases. Twenty-nine (94%) patients achieved a clinical partial response, including 35% of patients who demonstrated radiographic improvement on eMRI. CONCLUSIONS: No pathologic complete response was noted in 31 patients treated with docetaxel and gefitinib. This combination was well tolerated, and did not result in increased surgical morbidity.

[source] Suppression of the postoperative neutrophil leucocytosis following neoadjuvant chemoradiotherapy for rectal cancer and implications for surgical morbidityCOLORECTAL DISEASE, Issue 6 2010S. F. Kerr Abstract Objective, The extent to which neoadjuvant chemoradiotherapy for rectal cancer influences postoperative morbidity is controversial. This study investigated whether this treatment suppresses the normal perioperative inflammatory response and explored the clinical implications. Method, Prospective databases were queried to identify 37 consecutive study patients undergoing definitive surgery following 5-FU/capecitabine-based chemoradiotherapy and 34 consecutive untreated control patients operated upon for rectal or rectosigmoid cancer. Preoperative (< 10 days) and postoperative (< 24 h) neutrophil counts, along with morbidity data, were confirmed retrospectively. Univariate and multivariate analyses assessed the apparent effect of chemoradiotherapy on change in neutrophil count. The latter's association with postoperative morbidity was then examined. Results, Sufficient data were available for 34 study and 27 control patients. Repeated-measures ANCOVA revealed significant differences between their perioperative neutrophil counts (P = 0.02). Of the other characteristics which differed between the groups, only age and tumour location were prognostically significant regarding perioperative change in neutrophil count. Accounting for relevant covariates, chemoradiotherapy was significantly associated with a suppressed perioperative neutrophil leucocytosis. Local postoperative complications affected 25 of 61 patients, who had lower perioperative neutrophil increases than their counterparts (P = 0.016). Conclusion, Chemoradiotherapy appears to suppress the perioperative inflammatory response, thereby increasing susceptibility to local postoperative complications. [source] | ||||||||||
