    LARGE HYPERPLASTIC POLYP DEVELOPING AFTER ENDOSCOPIC MUCOSAL RESECTION OF GASTRIC ADENOMA IN A PATIENT RECEIVING IMMUNOSUPPRESSIVE THERAPY

    DIGESTIVE ENDOSCOPY, Issue 2 2006
    Geum-Youn Gwak
    A 59-year-old man underwent endoscopic mucosal resection (EMR) for gastric adenoma. He had suffered from end-stage renal disease for several years and had received renal transplantation some 5 months before EMR. Subsequently, he took immunosuppressive agents. Follow-up gastrofiberscopy 6 months after EMR showed a sessile polyp at the resection site twice as large as the original adenoma; biopsy specimens revealed a hyperplastic nature. At the time of writing, this hyperplastic polyp has neither increased in size nor developed adenomatous or carcinomatous changes by histological examinations over the past 5 years. Therefore, this is a case of hyperplastic polyp occurring at the gastric adenoma resection site, and suggests the possible effect of immunosuppressive therapy on the post-EMR healing process and hyperplastic polyp development.

    Endoscopic mucosal resection has been recognized as a standard method for treating mucosal tumors of the stomach in Japan. In our department, we have treated mucosal defects after this procedure by using metallic clips to prevent and manage complications related to endoscopic mucosal resection. In the present study, we explain the new technique, the ,loop-and-clips' method, which uses clips and a detachable snare to close large mucosal defects after endoscopic mucosal resection. [source]


    ENDOSCOPIC MUCOSAL RESECTION AND SUBMUCOSAL DISSECTION METHOD FOR LARGE COLORECTAL TUMORS

    DIGESTIVE ENDOSCOPY, Issue 2004
    Yasushi Sano
    ABSTRACT The goal of endoscopic mucosal resection (EMR) is to allow the endoscopist to obtain tissue or resect lesions not previously amenable to standard biopsy or excisional techniques and to remove malignant lesions without open surgery. In this article, we describe the results of conventional EMR and EMR using an insulation-tipped (IT) electrosurgical knife (submucosal dissection method) for large colorectal mucosal neoplasms and discuss the problems and future prospects of these procedures. At present, conventional EMR is much more feasible than EMR using IT-knife from the perspectives of time, money, complication, and organ preservation. However, larger lesions tend to be resected in a piecemeal fashion; and it is difficult to confirm whether EMR has been complete. For accurate histopathological assessment of the resected specimen en bloc EMR is desirable although further experience is needed to establish its safety and efficacy. Further improvements of in EMR with special knife techniques are required to simply and safely remove large colorectal neoplasms. [source]


    THE TECHNICAL FUNDAMENTALS OF ENDOSCOPIC MUCOSAL RESECTION IN THE COLON: OUR METHOD

    DIGESTIVE ENDOSCOPY, Issue 2004
    Yasushi Oda
    ABSTRACT Endoscopic mucosal resection (EMR) is the technique used to resect flat or depressed tumors or larger tumors such as laterally spreading tumors with marginal normal mucosa. Recently, endoscopic mucosal dissection technique has been rapidly accepted, mainly in early gastric cancer in Japan. We need to have firm knowledge of EMR technique in the colon for recovery as we advance this new technique. We describe our conventional EMR method practically. EMR should be performed to locate the target lesion at down side to perform sure EMR. The ideal shape of upheaval by saline injection is hemisphere. The needle sheath and snare should be taken out a little of the endoscopy to manipulate firmly. Another technique of secure EMR is the snare manipulation. We prefer that the shape of the snare is circular and the snare is hard. It is important while trapping to press the target lesion with both the whole snare circle and the end of the sheath. With these fundamental procedures we could resect the target lesions at will. [source]

    Background: In liver surgery, the increase in advancement of laparoscopic equipment has allowed the feasibility and safety of complex laparoscopic liver resection. However, blood loss and the potential risk of gas embolism seem to be the main obstacles. In this study, we successfully used the InLine radiofrquency ablation (RFA) device to carry out laparoscopic hand-assisted liver resection in pigs. Methods: Under general anaesthesia with tracheal intubation, pigs underwent InLine RFA-assisted laparoscopic liver resection. After installation of Hand Port and trocars, the InLine RFA device was introduced through Hand Port system and inserted into the premarked resection line. Then the generator was turned on and the power was applied according to the power setting. The resection was finally carried out using diathermy or stapler. For the control group, resection was simply carried out by diathermy or stapler. Results: Eight Landrace pigs underwent 23 liver resections. Blood loss was reduced significantly in the InLine group (P < 0.001) when compared with control group in both surgical methods (diathermy and stapler). Conclusion: In this study, we successfully carried out InLine RFA-assisted laparoscopic liver resection in both stapled and diathermy group. We showed that there was a highly significant difference between InLine and other liver resection techniques laparoscopically. [source]


    CR10 LAPAROSCOPIC RIGHT HEMICOLECTOMY PERFORMED DURING THE ,LEARNING CURVE PHASE' DOES NOT IMPACT ON ONCOLOGICAL RESECTION

    E. Mignanelli
    Purpose Laparoscopic colectomy for the management of colonic neoplasia is technically feasible and increasingly popular. It is expected that the laparoscopic operation deliver similar oncological clearance to open operation. The ,learning curve' for laparoscopic right hemicolectomy has been estimated to be 20 cases and is now set as a guideline by ASCRS. This study was performed to compare histopathology specimens following laparoscopic right hemicolectomy (LRH) performed during the ,learning curve' phase with those following open right hemicolectomy (ORH) to evaluate oncological clearance of colonic neoplasms. Methods 125 patients were identified as having undergone right hemicolectomy by two surgeons for colonic neoplasia from January 2001. Data regarding patient details and tumour pathology were obtained by retrospective case note review. Thirty-five patients underwent LRH compared to 90 who had ORH during the same period. Histopathology from the two groups were compared for length of specimen resected, proximal and distal resection margins, size of tumour resected or number of lymph nodes harvested. Analysis was performed using Student's T-test. Results The two groups were matched with respect to age, sex and tumour characteristics. There was no significant difference between the groups in terms of length of specimen resected (p = 0.37), proximal (p = 0.29) and distal (p = 0.40) resection margins, size of tumour resected (p = 0.37) or number of lymph nodes harvested (p = 0.58). Conclusions ,Learning curve' laparoscopic right hemicolectomy allows similar lymphovascular clearance to traditional open surgery. [source]


    HP10 LAPAROSCOPIC RESECTION OF SUBMUCOSAL GASTRIC LESIONS , THE WHANGAREI EXPERIENCE

    ANZ JOURNAL OF SURGERY, Issue 2007
    J. Y. Yang
    Purpose To evaluate safety of laparoscopic resection of submucosal gastric lesions performed in Whangarei Based Hospital. Methodology From November 2002 to December 2006, 8 consecutive patients underwent the above mention surgery. (M : F = 5 : 3; Average age 63 [range, 43,83]). All patients underwent pre-operative gastroscopy. Wedge resections were performed for anterior wall lesions. (n = 3). Posterior wall lesions were resected via transgastric approach. (n = 4). Retroperitoneal resection was performed for the foregut duplication cyst. (n = 1). All except one lesion were resected using endoscopic GIA stapler. The medical records of the patients were reviewed retrospectively. Results All patients were successfully treated laparoscopically. No conversion to open surgery. Pathology included: Gastrointestinal-stromal tumor (GIST) (n = 5), Malignant leiomyosarcoma (n = 1), Ectopic pancreas (n = 1), and Foregut duplication cysts (n = 1). All achieved adequate negative surgical margin. Average operation time was 106.14 minutes. [Range, 75,150]. Average length of hospital stay was 3.42 days [range, 1,5]. Complication included one wound infection, and one pyloric stenosis. Average length of follow up was 10.96 months [range, 0.46,31.73]. No recurrence detected and all are still alive till date. Conclusion Laparoscopic resection of submucosal gastric lesions is a safe and appropriate alternative to open surgery. Its main advantage over open technique includes shorter length of hospital stay, lower recurrence rate and lower mortality rates. Surgical technique depends very much on tumor size and location. Outcome of the patients described from our centre is comparable to the others published till date. [source]


    RISKS AND CONSEQUENCES OF INCIDENTAL PARATHYROIDECTOMY DURING THYROID RESECTION

    ANZ JOURNAL OF SURGERY, Issue 1-2 2007
    Rebecca S. Sippel
    Background: Inadvertent removal of the parathyroid glands during elective thyroid surgery occurs more frequently in certain high-risk patients and can lead to symptomatic hypocalcaemia. Methods: A case,control study was carried out at a tertiary referral, academic medical centre between May 1994 and August 2001. Five hundred and thirteen patients underwent thyroid resection. Pathology reports were reviewed to identify patients who had the inadvertent removal of a parathyroid gland during their thyroid surgery. Thirty-three (6.4%) patients had inadvertent resection of a parathyroid gland. The outcomes of these 33 patients (INCIDENTAL) were compared with the other 480 patients who did not have resection of parathyroid tissue (NO INCIDENTAL). Results: Risk factors for inadvertent parathyroid resection included younger age (P = 0.003), bilateral thyroid resection (P = 0.001) and malignant pathology (P = 0.002). Factors that did not increase the risk of incidental parathyroidectomy included gland weight, sex, presence of a goitre, previous neck exploration and concurrent lymph node dissection. In the INCIDENTAL group 24% had a postoperative calcium levels less than 7.0 mg/dL (P = 0.001). Symptomatic hypocalcaemia developed in 12% of INCIDENTAL patients, compared to 4% in the NO INCIDENTAL group (P = 0.06). Conclusion: Incidental removal of parathyroid tissue occurred in 6.4% of thyroid resections. Younger patients undergoing a total or subtotal thyroidectomy for malignancy were at the highest risk. These patients had lower postoperative calcium levels, but the majority (88%) experienced no clinical consequences. [source]


    EFFECT OF RESECTION AND OUTCOME IN PATIENTS WITH RETROPERITONEAL SARCOMA

    ANZ JOURNAL OF SURGERY, Issue 6 2006
    Antonio Chiappa
    Background: A consecutive series of 47 patients with retroperitoneal sarcoma (RPS) were resected and prospectively followed. Method: Between July 1994 and March 2005, 47 patients (24 men, 23 women; mean age, 56 years; range, 17,82 years) were evaluated. Results: A total of 23 patients had primary RPS and 24 patients had recurrent RPS. A total of 30 out of 47 patients (64%) underwent removal of contiguous intra-abdominal organs. The peroperative mortality was nil and significant preoperative complications occurred in eight cases only (17%). High tumour grade and incomplete resection were significant variables for a worse survival in all 47 patients, both in the univariate and multivariate analyses (P = 0.008 and P = 0.016, respectively). Among 28 radically resected patients, only histological grade affected overall survival (90% 5-year survival for low-grade tumour vs 26% 5-year survival for high-grade tumour; P = 0.006) with a similar effect noted for disease-free survival. Conclusions: Histological grade was the only factor that affected overall and disease-free survival for RPS tumours. An aggressive surgical approach in both primary and recurrent RPS is associated with long-term survival. [source]

    Longstanding malformation of right sided pinna in an elderly man

    CONGENITAL ANOMALIES, Issue 1 2010
    Deeke Yolmo
    ABSTRACT The pinna is the second most common site for external ear vascular malformation in the head and neck. These malformations are relatively uncommon in adults and can pose difficult therapeutic challenges. We hereby present a case of a 69-year-old man with a congenital lesion in the right pinna consistent with an arteriovenous malformation. The lesion was complicated by ulceration and bleeding for 6 months prior to presentation. Resection of pinna was carried out, and satisfactory functional and esthetic results were obtained. There was no recurrence at 22 months of regular follow up. [source]


    Lateral Wedge Resection: A Simple Technique for Repairing Involutional Lower Eyelid Entropion

    DERMATOLOGIC SURGERY, Issue 9 2010
    IGAL LEIBOVITCH MD
    BACKGROUND Lower lid involutional entropion is a common eyelid pathology affecting the elderly population. Most of the reported surgical techniques are mainly based on a lateral tarsal strip anchored to the orbital rim. OBJECTIVES To report the surgical outcome using a simple single-stitch lateral wedge technique to repair involutional lower entropion. METHODS This single-surgeon, retrospective, noncomparative cases series included all patients with involutional lower eyelid entropion who were operated on using the lateral wedge technique. RESULTS Fifty-eight eyelids of 52 patients (46 unilateral, 6 bilateral; 27 men, 25 women; age, mean 6710; range 50,85) underwent surgical repair. Immediate resolution of entropion and associated ocular symptoms was achieved in 55 eyelids (94.9%). One case had postoperative ectropion that completely resolved spontaneously after 4 weeks, and one had wound dehiscence that healed completely without any intervention. Another patient had residual entropion that resolved after an additional surgical repair. No other cases of recurrence were noted during a mean follow-up period of 16 months (range 6,24 months). CONCLUSION This minimally invasive single-stitch lateral wedge technique is a simple and effective procedure for repairing involutional lower eyelid entropion and is associated with low recurrence and complication rates. Igal Leibovitch, MD, has indicated no significant interest with commercial supporters. [source]


    ENDOSCOPIC SUBMUCOSAL DISSECTION FOR EARLY GASTRIC CANCER USING MAGNIFYING ENDOSCOPY WITH A COMBINATION OF NARROW BAND IMAGING AND ACETIC ACID INSTILLATION

    DIGESTIVE ENDOSCOPY, Issue 3 2008
    Kyosuke Tanaka
    Demarcation of early gastric cancers is sometimes unclear. Enhanced-magnification endoscopy with acetic acid instillation and magnifying endoscopy with a narrow band imaging (NBI) system have been useful for recognition of demarcation of early gastric cancers. We report a patient with early gastric cancer who underwent a successful endoscopic submucosal dissection (ESD) by magnifying endoscopy with the combined use of NBI and acetic acid instillation. A 72-year-old man with early gastric cancer underwent ESD. Demarcation of the lesion was not clear, but magnifying endoscopy using the combination of NBI and acetic acid clearly revealed the demarcation. ESD was carried out after spots were marked circumferentially. We identified the positional relation between the demarcation and all markings. Resection of the lesion was on the outside of the markings. Histopathologically, the lesion was diagnosed as a well-differentiated adenocarcinoma limited to the mucosa. The margins were carcinoma free. Magnifying endoscopy combining the use of NBI with acetic acid instillation is simple and helpful for identifying the demarcation of early gastric cancer. This method may be useful in increasing the rate of complete resection by ESD for early gastric cancer. [source]


    The Results of Questionnaire about Endoscopic Mucosal Resection in the Stomach

    DIGESTIVE ENDOSCOPY, Issue 2003
    MOTOTSUGU KATO
    Isolated exfoliation method of gastric endoscopic mucosal resection (EMR) as a new technique has not yet reached the popularity of the conventional EMR techniques. From the results of a questionnaire about EMR in the stomach, the isolated exfoliation method has the advantage of permitting en bloc and histologically complete resection regardless of lesion size. However, this method has the disadvantage of long performance time and high frequency of complication as well as the need for a high level of technical skill. New devices and ideas are needed for the development of the isolated exfoliation method. [source]

    Seizure Outcome after Resection of Supratentorial Cavernous Malformations: A Study of 168 Patients

    EPILEPSIA, Issue 3 2007
    Christian R. Baumann
    Summary:,Purpose: The optimal management of cerebral cavernous malformations (CCMs) with epileptic seizures is still a matter of debate. The aim of our study was to examine seizure outcome in the largest published series of surgically treated patients with epilepsy due to a supratentorial CCM, and to define predictors for good surgical outcome. Methods: We retrospectively studied 168 consecutive patients with a single supratentorial CCM and symptomatic epilepsy in a multicenter study. Pre- and postoperative clinical examinations, age at epilepsy onset, age at operation, type of symptoms due to the CCM (seizures, headache, hemorrhage, focal deficits), type and frequency of epileptic seizures, and the localization and size of the CCM were assessed. Seizure outcome was determined in the first, second, and third postoperative years. Results: The CCM was completely resected in all patients. More than two thirds of the patients were classified as seizure free in the first 3 postoperative years. Predictors for good seizure outcome were age older than 30 years at the time of surgery, mesiotemporal CCM localization, CCM size <1.5 cm, and the absence of secondarily generalized seizures. No mortality occurred in our series, but only mild postoperative neurologic deficits in 12 (7%) patients. Conclusions: Considering the natural history of CCMs, the favorable neurologic and seizure outcome, surgical resection of CCMs should be considered in all patients with supratentorial CCMs and concomitant epilepsy, irrespective of the presence or absence of predictors for a favorable seizure outcome.

    Dynamic Changes of Ictal High-Frequency Oscillations in Neocortical Epilepsy: Using Multiple Band Frequency Analysis

    EPILEPSIA, Issue 2 2007
    Ayako Ochi
    Summary:,Purpose: To characterize the spatial and temporal course of ictal high-frequency oscillations (HFOs) recorded by subdural EEG in children with intractable neocortical epilepsy. Methods: We retrospectively studied nine children (four girls, five boys; 4,17 yr) who presented with intractable extrahippocampal localization-related epilepsy and who underwent extraoperative video subdural EEG (1000 Hz sampling rate) and cortical resection. We performed multiple band frequency analysis (MBFA) to evaluate the frequency, time course, and distribution of ictal HFOs. We compared ictal HFO changes before and after clinical onset and postsurgical seizure outcomes. Results: Seventy-eight of 79 seizures showed HFOs. We observed wide-band HFOs (,250Hz, ,120 electrodes) in six patients either with partial seizures alone (three patients) or with epileptic spasms (three patients). Three patients with partial seizures that secondarily generalized had wide-band HFOs (,170 Hz) before clinical onset and sustained narrow-band HFOs (60,164 Hz) with electrodecremental events after clinical onset (,28 electrodes). In four postoperatively seizure-free patients, more electrodes recorded higher-frequency HFOs inside the resection area than outside before and after clinical seizure onset. In five patients with residual seizures, electrodes recorded more HFOs that were of higher or equal frequency outside the surgical area than inside after clinical onset. Conclusion: For partial seizures alone and epileptic spasms, more electrodes recorded only wide-band HFOs; for partial seizures that secondarily generalized, fewer electrodes recorded wide-band HFOs, but in these seizures electrodes also recorded subsequent sustained narrow-band ictal HFOs. Resection of those brain regions having electrodes with ictal, higher HFOs resulted in postsurgical seizure-free outcomes. [source]


    Seizure Outcome after Resection of Cavernous Malformations Is Better When Surrounding Hemosiderin-stained Brain Also Is Removed

    EPILEPSIA, Issue 3 2006
    Christian R. Baumann
    Summary:,Purpose: Considering the epileptogenic effect of cavernoma-surrounding hemosiderin, assumptions are made that resection only of the cavernoma itself may not be sufficient as treatment of symptomatic epilepsy in patients with cavernous malformations. The purpose of this study was to test the hypothesis whether seizure outcome after removal of cavernous malformations may be related to the extent of resection of surrounding hemosiderin-stained brain tissue. Methods: In this retrospective study, 31 consecutive patients with pharmacotherapy-refractory epilepsy due to a cavernous malformation were included. In all patients, cavernomas were resected, and all patients underwent pre- and postoperative magnetic resonance imaging (MRI). We grouped patients according to MRI findings (hemosiderin completely removed versus not/partially removed) and compared seizure outcome (as assessed by the Engel Outcome Classification score) between the two groups. Results: Three years after resection of cavernomas, patients in whom hemosiderin-stained brain tissue had been removed completely had a better chance for a favorable long-term seizure outcome compared with those with detectable postoperative hemosiderin (p = 0.037). Conclusions: Our study suggests that complete removal of cavernoma-surrounding hemosiderin-stained brain tissue may improve epileptic outcome after resection of cavernous malformations. [source]


    Cortical Resection with Electrocorticography for Intractable Porencephaly-related Partial Epilepsy

    EPILEPSIA, Issue 1 2005
    Koji Iida
    Summary:,Purpose: We evaluated the results of cortical resection of epileptogenic tissue for treatment of intractable porencephaly-related epilepsy. Methods: We examined clinical features, electrophysiological data, surgical findings, and seizure outcomes after cortical resection in eight patients with intractable epilepsy related to porencephalic cysts. Results: All eight patients had hemiparesis. Five retained motor function in the hemiparetic extremities; six retained visual fields. All had partial seizures, six with secondary generalization. Seven patients had simple and three had complex partial seizures (CPSs); two also had drop attacks. Four patients had multiple seizure types. Long-term scalp video-EEG (LVEEG) localized interictal epileptic abnormalities that anatomically corresponded to the cyst location in three patients. LVEEG recorded ictal-onset zones in five; these anatomically corresponded to the cyst location in three of the five. EEG recorded generalized seizures in two patients, hemispheric in one, and multifocal in two. Intraoperative electrocorticography (ECoG) revealed interictal epileptic areas extending beyond the margins of the cyst in seven patients. We resected ECoG-localized interictal epileptic areas completely in five patients and partially in two. Cortical resection was based on seizure semiology and LVEEG in one patient whose ECoG showed no epileptiform discharges. After a minimum follow-up of 1 year, six patients had excellent seizure outcome (Engel class I), and two had a >90% seizure reduction (Engel class III) without complications. Conclusions: Cortical resection guided by ECoG allows preservation of motor function and visual field and provides an effective surgical procedure for treatment of intractable epilepsy secondary to porencephaly.

    Acute Postoperative Seizures after Frontal Lobe Cortical Resection for Intractable Partial Epilepsy

    EPILEPSIA, Issue 6 2003
    Simona Tigaran
    Summary: Purpose: To evaluate the incidence and prognostic importance of acute postoperative seizures (APOSs) occurring in the first week after a focal corticectomy in patients with partial epilepsy of frontal lobe origin. Methods: We retrospectively evaluated 65 patients who underwent a frontal lobe cortical resection for intractable partial epilepsy between April 1987 and December 2000. All patients were followed up for a minimum of 1 year after surgery. Results: APOSs occurred in 17 (26%) patients. None of the following factors was shown to be significantly associated with the occurrence of APOSs: gender, duration of epilepsy, etiology for seizure disorder, use of subdural or depth electrodes, surgical pathology, or postoperative risk factor for seizures. Patients with APOSs were older at seizure onset and at the time of surgery (p = 0.003 and p = 0.05, respectively). At last follow-up, patients who had APOSs had a seizure-free outcome similar to that of individuals without APOSs (47.1% vs. 50.0%; p = 0.77). Patients with APOSs appeared less likely to have a favorable outcome [i.e., fewer than three seizures per year and >95% decrease in seizure activity (58.8 vs. 70.8%; p = 0.35)]. This result may not have reached statistical significance because of the sample size. No evidence suggested that precipitating factors or the timing of APOSs was an important prognostic factor. Conclusions: The presence of APOSs after frontal lobe surgery for intractable epilepsy does not preclude a significant reduction in seizure tendency. These findings may be useful in counseling patients who undergo surgical treatment for frontal lobe epilepsy. [source]


    Multiple Subpial Transections: The Yale Experience

    EPILEPSIA, Issue 2 2001
    Lisa P. Mulligan
    Summary: ,Purpose: Although resection of an epileptogenic region is the mainstay of epilepsy surgery, epileptogenic areas in functionally critical cortex cannot be approached in that manner. Multiple subpial transection (MST) was developed to treat those refractory seizures without causing unacceptable neurologic deficit. We review our experience with this technique. Methods: Twelve patients who underwent MST with or without resection between 1990 and 1998 were retrospectively reviewed with regard to seizure and neurologic outcome, and predictive factors. Results: Five (42%) of 12 patients obtained a significant improvement in seizure frequency, and two other patients had a marked decrease in the severity of their seizures. Resection with MST reduced seizure frequency more, but this was not a significant difference. No predictive factors for outcome were identified. Only one patient sustained any persistent neurologic deficit. Conclusions: In selected patients, MST may be a viable alternative when the epileptogenic focus lies in unresectable cortex. A multicenter study with appreciable patient numbers will be necessary to define predictive factors for success. [source]


    Palatal adhesion: The treatment of unilateral palatal paralysis after high vagus nerve injury

    HEAD & NECK: JOURNAL FOR THE SCIENCES & SPECIALTIES OF THE HEAD AND NECK, Issue 8 2002
    James L. Netterville MD
    Abstract Background Resection of skull base tumors commonly necessitates intraoperative sacrifice of lower cranial nerves at the level of the jugular foramen. Sequelae of unilateral vagus nerve loss include ipsilateral laryngeal paralysis, ipsilateral palatal and pharyngeal paralysis, and velopharyngeal incompetence (VPI) marked by hypernasal speech and nasopharyngeal reflux of liquids during swallowing. Methods Palatal adhesion (PA), a procedure whereby the unilaterally paralyzed palate is attached to the posterior pharyngeal wall, decreases the size of the velopharyngeal port and minimizes the symptoms. This study assessed the outcome of PA in 31 patients with VPI secondary to proximal vagus nerve injury. Results PA decreased postoperative nasality in 96% of patients. Nasopharyngeal reflux was significantly improved in 83%. Three patients (11%) had minor wound breakdown postoperatively, all of which healed completely with conservative management. Conclusion PA offers a favorable result with minimal concomitant morbidity and is recommended for patients with VPI secondary to unilateral proximal vagus nerve paralysis. 2002 Wiley Periodicals, Inc.

    Helicobacter pylori Eradication Therapy May Facilitate Gastric Ulcer Healing After Endoscopic Mucosal Resection: A Prospective Randomized Study

    HELICOBACTER, Issue 6 2008
    Jae Hee Cheon
    Abstract Background and Aim:, It remains unclear whether Helicobacter pylori eradication therapy affects the healing rate of iatrogenic ulcers following endoscopic mucosal resection (EMR) for gastric tumors. The aim of our study was to prospectively evaluate the effect of H. pylori eradication therapy on gastric ulcer healing after EMR. Methods:, After EMR, patients were randomly assigned to either the H. pylori eradication group (Hp group) (lansoprazole 30 mg, amoxicillin 1000 mg, and clarithromycin 500 mg, twice a day for 7 days) or the noneradication group (proton pump inhibitor, PPI group) (lansoprazole 30 mg, twice a day for 7 days). Four weeks after EMR, the ulcer stages and size were compared between the two groups. Moreover, ulcer-related symptoms, bleeding rates, adverse effects, and drug compliance were compared. Results:, A total of 64 patients were enrolled. Of these, 17 patients were excluded from the study. The two groups were comparable in terms of baseline clinicopathologic characteristics. Four weeks after EMR, the two groups did not differ with respect to ulcer stage (p = .475) or ulcer-related symptoms (p = .399). However, the ulcer reduction ratio was significantly higher in the Hp group (0.028 0.024 vs. 0.065 0.055, p < .05). No differences were observed between the two groups with regard to drug compliance, adverse drug event rates, or bleeding rates. Conclusions:, Our results suggest that H. pylori eradication therapy might improve the ulcer healing rate after EMR. [source]

    Resection of hilar cholangiocarcinoma with left hepatectomy after pre-operative embolization of the proper hepatic artery

    HPB, Issue 2 2010
    Yoshikazu Yasuda
    Abstract Background:, Right or right-extended hepatectomy including the caudate lobe is the most common treatment for hilar cholangiocarcinoma (HC). A 5-year survival of up to 60% can be achieved using this procedure if R0-resection is obtained. However, for some patients a left-sided liver resection is necessary to obtain radical resection. The close relationship between the right hepatic artery and the HC in these patients frequently limits the ability to achieve a radial R0-resection without difficult vascular reconstruction. The aim of the present study was to describe the outcome of patients who underwent pre-operative embolization of the proper hepatic artery in an effort to induce development of arterial collaterals thus allowing the resection of the proper and right hepatic artery without vascular reconstruction. Methods:, In patients presenting with HC who were considered to require a left hepatic lobectomy and in whom pre-operative work up revealed possible tumour invasion of the right hepatic artery, transcatheter arterial embolization (TAE) of the proper hepatic artery or the left and right hepatic arteries was performed. Three weeks later, a left-sided hepatectomy with resection of all portal structures except the portal vein was performed. Results:, In six patients, pre-operative embolization of the proper hepatic artery was performed. Almost instantaneously in all six patients arterial flow signals could be detected in the liver using Doppler ultrasonography. No patient died peri-operatively. In all six patients an R0 radial resection was achieved and in three an R0 proximal transection margin was obtained. All post-operative complications were managed successfully using percutaneous drainage procedures. No patient developed local recurrence and two patients remain disease free more than 7 years after surgery. Summary:, After pre-operative embolization of the proper hepatic artery, resection of the HC with left hepatectomy is a promising new approach for these technically demanding patients, giving them the chance of a cure.

    Abstract Objective:, To assess perioperative mortality following resection of biliary tract cancer within the U.S. Background:, Resection remains the only curative treatment for biliary tract cancer. However, current data on operative mortality after surgical resections for biliary tract cancer are limited to small and single-center studies. Methods:, Using the Nationwide Inpatient Sample 1998,2006, a cohort of patient-discharges was assembled with a diagnosis of biliary tract cancer, including intrahepatic bile duct, extrahepatic bile duct, and gall bladder cancers. Patients undergoing resection, including hepatic resection, bile duct resection, pancreaticoduodenectomy, and cholecystectomy, were retained. The primary outcome measure was in-hospital mortality. Categorical variables were analyzed by chi-square. Multivariable logistic regression was performed to identify independent predictors of in-hospital mortality following resection. Results:, 31 870 patient-discharges occurred for the diagnosis of biliary tract cancer, including 36.2% intrahepatic ductal, 26.7% extrahepatic ductal, and 31.1% gall bladder. Of the total, 18.6% underwent resection: mean age was 69.3 years (median 70.0); 60.8% were female; 73.7% were white. Overall inpatient surgical mortality was 5.6%. Independently predictive factors of mortality included patient age ,50 (vs. <50; age 50,59 odds ratio [OR] 5.51, 95% confidence interval [CI] 1.70,17.93; age 60,69 OR 7.25, 95% CI 2.29,22.96; age , 70 OR 9.03, 95% CI 2.86,28.56), the presence of identified comorbidities (congestive heart failure, OR 3.67, 95% CI 2.61,5.16; renal failure, OR 4.72, 95% CI 2.97,7.49), and admission designated as emergent (vs. elective; OR 1.82, 95% CI 1.39,2.37). Conclusion:, Increased in-hospital mortality for patients undergoing biliary tract cancer resection corresponded to age, comorbidity, hospital volume, and emergent admission. Further study is warranted to utilize these observations in promoting early detection, diagnosis, and elective resection. [source]


    Guidelines for palliative surgery of cholangiocarcinoma

    HPB, Issue 3 2008
    H. Witzigmann
    Abstract The aims of the guidelines are to help assess the evidence for palliation surgery in patients with cholangiocarcinoma (CCA). The guidelines are classified in accordance with the location of the primary lesion, i.e. intrahepatic, hilar, and distal. They are based on comprehensive literature surveys, including results from randomized controlled trials, systematic reviews and meta-analysis, and cohort, prospective, and retrospective studies. Intrahepatic CCA, i.e. resection of lymph-node-positive tumors and R1/R2 resections have not been shown to provide survival benefit: Evidence levels: 2b, 4; Recommendation grade C. Hilar CCA: R1 resection is justified as a very efficient palliation. Non-surgical biliary stenting is the first choice of palliative biliary drainage. Distal CCA: Resection of lymph-node-positive tumours and R1/R2 resections should be performed. Non-surgical stenting is regarded as the first choice of palliation for patients with short life expectancy. For patients with longer projected survival, surgical bypass should be considered. Palliative resections have a relevant beneficial impact on the outcome of patients with distal and hilar CCA. Non-surgical stenting is the first choice of palliative biliary drainage for patients with hilar CCA and for those with distal CCA and short life expectancy. For patients with distal CCA and longer projected survival, surgical bypass should be considered. [source]
