AbstractBackgroundRepair of complex incisional hernias poses a major challenge.AimThe aim of this study was to review the outcomes of the modified Rives‐Stoppa repair of complex incisional hernias using a synthetic prosthesis.MethodsWe reviewed patients undergoing a modified Rives‐Stoppa repair of complex incisional hernias from 1990 to 2003. Patients were followed through clinic visits and mailed questionnaires. Follow‐up data were complete in all patients (mean 70 months, range 24–177 months), and 87% of patients completed a mailed questionnaire. Primary outcome included mortality, morbidity, and hernia recurrence. Secondary outcome measures were duration of hospital stay, long‐term abdominal wall pain, and self‐reported patient satisfaction.ResultsAltogether, 254 patients underwent a modified Rives‐Stoppa repair. Among them, 60% had a significant co‐morbidity, and 30% had one or more previously failed hernia repairs. Mortality was zero, and overall morbidity was 13% (wound infection 4%, prosthetic infection 3%, seroma/hematoma 4%). The overall hernia recurrence rate was 5%, including explantation of mesh because of infection. Wound/prosthetic infection was predictive for hernia recurrence (31% vs. 4%, p = 0.003). Among the respondents, 89% reported overall satisfaction with their repair.ConclusionThe Rives‐Stoppa repair of complex incisional hernias using synthetic prosthetic materials is safe with a low recurrence rate (5%) and high patient satisfaction. Postoperative wound infection is a risk factor for hernia recurrence.

Abstract Percutaneous cholecystostomy offers a potentially important therapeutic modality for critically ill patients with acute cholecystitis who represent a high risk for general anaesthesia. The aim of the study was to assess experience with percutaneous cholecystostomy in resolving the acute episode of cholecystitis without operative intervention. Twenty-two consecutive patients with a clinical diagnosis of acute cholecystitis underwent the procedure. All were at high risk for general anaesthesia, and all but one developed cholecystitis while hospitalized for another co-morbid condition; 14 were in an intensive care unit. Twenty-one of the 22 patients proved to have acute cholecystitis (11 acalculous, ten cholelithiasis). There were no acute technical complications. Toxaemia resolved in 17 of the 21 patients with acute cholecystitis. Acute cholecystitis failed to resolve in three patients; all died within 48 h from overwhelming generalized sepsis. One patient required emergency cholecystectomy for bile peritonitis when the cholecystostomy catheter became dislodged 24 h after placement. The 60-day mortality rate for the acalculous and calculous patient groups was 55 and 20 per cent, respectively. Only three interval cholecystectomies have been performed at a mean follow-up of 19 months. In conclusion, percutaneous cholecystostomy may be the procedure of choice for the management of acute cholecystitis in the very high-risk critically ill patient. If symptoms fail to resolve quickly, ongoing sepsis, cholangitis or gallbladder necrosis should be suspected.

AbstractBackgroundSolid pseudopapillary neoplasms of the pancreas are rare malignant lesions of the pancreas that typically occur in young women. Large series from any one centre are notably absent in the literature. The aim of this study was to determine long-term outcomes of operative therapy.MethodsThe records of all 14 patients diagnosed with pseudopapillary neoplasms of the pancreas over 17 years were reviewed.ResultsThirteen of the 14 patients were female and the mean age at diagnosis was 30 years. Solid pseudopapillary neoplasm was suspected in only half of these patients before operation. On computed tomography, ultrasonography and/or magnetic resonance imaging, three lesions were solid, three were largely cystic, and five had solid and cystic components. All 14 patients underwent surgical exploration and curative resections were possible in 13, including distal pancreatectomy in nine, pancreaticoduodenectomy in three and resection of a local intraperitoneal recurrence in one patient. After follow-up ranging from 3 months to 20 years, 12 patients were alive, including one who had undergone re-exploration and resection of local and subcutaneous recurrences 9 years previously.ConclusionSolid pseudopapillary neoplasm of the pancreas should be considered in the differential diagnosis of any solid or partly cystic pancreatic mass in women aged less than 35 years. An attempt at en bloc resection without formal lymphadenectomy should be undertaken, including resection of synchronous or metachronous distant metastases.

AbstractOur aim was to examine the long‐term success of cholecystoenterostomy performed for the relief of benign extrahepatic biliary obstruction. Concern about the ability of cholecystoenterostomy to provide reliable long‐term biliary decompression has led many to abandon its use for benign biliary obstruction. Thirty‐four patients who underwent cholecystoenterostomy for benign biliary obstruction over a 17‐year period were reviewed. Patients were followed until cholecystoenterostomy failure, death, or to date. Failure was defined as recurrent biliary obstruction or cholangitis requiring therapeutic intervention. Mean follow‐up was 8.0 years. Early postoperative morbidity occurred in 11 patients (32%), but only one early complication (cholangitis) was related directly to the cholecystoenteric anastomosis. Five patients (15%) experienced late biliary tract complications related directly to the cholecystoenterostomy including recurrent biliary stones with biliary obstruction in four and anastomotic stricture in one. All required reoperation and conversion to choledochoenterostomy at a mean of 112 months. Cholecystoenterostomy can provide reasonably effective long‐term biliary decompression in selected patients with benign biliary obstruction.

Abstract Background The ability to deliver nutrition enterally after operation has been a significant advance in managing patients after major intra-abdominal operations. Methods The experience of a single surgeon at a tertiary referral hospital over a 10-year period with insertion and use of 500 consecutive needle catheter jejunostomies (NCJs) was reviewed critically from prospectively collected data. Results The NCJ was used to deliver nutrition in 93 per cent, fluid and electrolytes in 95 per cent, and various medications in the postoperative period in the majority of patients. There were three major complications: small bowel obstruction and pneumatosis intestinalis in one and two patients respectively. Minor complications included diarrhoea (15 per cent), abdominal distension (15 per cent), abdominal cramps (3 per cent), subcutaneous infection at the insertion site (1 per cent) and catheter occlusion precluding use (1 per cent). In 16 patients, the NCJ was replaced percutaneously with a larger-bore catheter for more prolonged enteral feeding at home after discharge. Conclusion Through the experience gained, indications are offered for the placement of NCJs and cautions are provided concerning appropriate use of an NCJ to provide nutritional support, fluid and electrolyte replacement or maintenance, and safe enteral administration of medication. Overall, an NCJ appears to allow safer, cheaper and equally effective delivery of nutrition compared with total parenteral nutrition after major intra-abdominal operations.
