Survey of minimally invasive surgery fellowship programs.

INTRODUCTION: Since there was no accrediting body for minimally invasive surgery fellowships, this investigation was performed to characterize minimally invasive surgery fellowships. MATERIALS AND METHODS: All minimally invasive surgery fellowships that were noted on the Society of American Gastrointestinal Endoscopic Surgeons website in July 2002 were sent a survey. Only those fellowships that had fellow(s) for the year 2001-2002 were included in the survey. All programs were contacted a second time if the survey was not returned. Incomplete responses were not included in the data. RESULTS: There were 78 fellowships listed, of which 16 had no fellow in 2001-2002, one which was not a minimally invasive surgery fellowship, and one which was listed twice. Of the 19 (32%) programs that responded, there was an average of 1.3 clinical fellows per program (range, 1-3). All clinical fellowships were of one year duration. There was an average of 3.2 attendings for each program. Thirty-two percent of program directors had attended a laparoscopic fellowship. The average program received 50 applications and interviewed 12 applicants for the year 2001-2002. The average fellow had 14 (range, 0-42) manuscripts, abstracts, and/or presentations either completed or in progress. Average minimally invasive cases performed was bariatric 95, colon 33, solid organ (liver, spleen, kidney, adrenal) 32, antireflux 36, hernia 54, and endoscopy 48. However, the range of these cases varied and the lowest number of cases for each category was bariatric 5, colon 3, solid organ 8, antireflux 1, hernia 6, and endoscopy 0. CONCLUSION: Minimally invasive surgery fellowships seem to be competitive for surgical residents. These fellowships vary in both research and clinical experience.

Central pancreatectomy for the resection of benign or low malignant potential neoplasms.

Central pancreatectomy is an uncommonly performed procedure that may be particularly useful for the removal of benign and low malignant potential lesions in the neck and body of the pancreas. This procedure may have fewer major complications and better preserve endocrine and exocrine function than the more commonly performed pancreaticoduodenectomy or distal pancreatectomy. We report our recent experience with central pancreatectomy and review the literature on this topic.

Intraperitoneal underlay ventral hernia repair utilizing bilayer expanded polytetrafluoroethylene and polypropylene mesh.

A prospective study of patients with ventral hernias was undertaken to study the experience with an open intraperitoneal underlay technique utilizing a bilayer prosthetic mesh. From September 1998 to March 2001, 102 patients underwent repair with a bilayer expanded polytetrafluoroethylene (ePTFE) and polypropylene mesh placed intraperitoneally and fixed in place with full-thickness abdominal muscle wall sutures to achieve a 5-cm underlay of the fascial defect circumferentially. There were 67 females and 35 males ranging in age from 29 to 76 years (mean 53 years). Average patient weight was 207 lb with 64 patients in the obese category. Forty patients presented with recurrent hernias. Mean operative time was 103 minutes with an average diameter hernia defect size of 15 cm. Median hospital stay was 3 days. There was no surgical mortality, and major morbidity occurred in six patients (2 wound infections, one deep vein thrombosis, one myocardial infarction, one pneumonia, and one pulmonary embolus). Mean follow-up is 28 months (range 12-42 months). No recurrence has been found with 100 per cent follow-up to date. No bowel obstruction or enteric fistulas have occurred during the follow-up period. The open intraperitoneal underlay mesh technique can be performed with a zero per cent early recurrence rate. Bilayer prosthetic mesh composed of ePTFE and polypropylene can be safely placed intraperitoneally without causing intestinal obstruction or enteric fistula.

Vascular complications associated with pancreaticoduodenectomy adversely affect clinical outcome.

BACKGROUND: Early survival after pancreaticoduodenectomy has improved, but its morbidity remains high. The purpose of this study is to determine how the intra-operative (OR) occurrence of major vascular complications affects the outcome of pancreaticoduodenectomy. METHODS: The medical records of 180 consecutive patients having pancreaticoduodenectomy from 1991 to 2001 were reviewed. Vascular complications were defined as "an unanticipated injury or thrombosis of a major vessel necessitating intervention." Age, sex, type of pancreaticoduodenectomy, tumor size, estimated blood loss, OR time, time in intensive care, post-OR hospitalization, and survival were compared. RESULTS: Eighteen vascular complications were identified. Differences in age, sex, and type of resection between patients with or without vascular complications were not significant. OR time, estimated blood loss, blood transfusions, tumor size, time in intensive care, and post-OR hospitalization were all significantly greater in patients with vascular complications. Median survival for patients with vascular complications was significantly shorter than for patients without vascular complications. Thirty-day mortality was greater in patients with vascular complications. CONCLUSION: Vascular complications significantly affect the outcome of pancreaticoduodenectomy increasing OR time, estimated blood loss, blood transfusion requirements, time in intensive care, post-OR hospitalization, and mortality.

Central pancreatectomy for a pancreatic ganglioneuroma in a patient with previous neuroblastoma.

This is a case presentation of a 28-year-old woman with a mass at the junction of the neck and the body of the pancreas and a childhood history of a resected adrenal neuroblastoma. A central pancreatectomy was performed in this patient. The pathology revealed a benign ganglioneuroma. Ganglioneuromas and their association with a neuroblastoma are briefly reviewed. The indications and contraindications for, as well as the advantages and disadvantages of, a central pancreatic resection are discussed.
