OBJECTIVE To evaluate the short-term outcomes for laparoscopic Roux-en-Y gastric bypass in 275 patients with a follow-up of 1 to 31 months. SUMMARY BACKGROUND DATA The Roux-en-Y gastric bypass is a highly successful approach to morbid obesity but results in significant perioperative complications. A laparoscopic approach has significant potential to(More)
HYPOTHESIS Computed tomography (CT) and ultrasonography (US) do not improve the overall diagnostic accuracy for acute appendicitis. DESIGN Retrospective review. SETTING University tertiary care center. PATIENTS Seven hundred sixty-six consecutive patients undergoing appendectomy for suspected appendicitis from January 1, 1995, to December 31, 1999. (More)
BACKGROUND Carbon dioxide is the current gas of choice for pneumoperitoneum, but hemodynamic and acid-base effects secondary to its systemic absorption have been reported. Various studies have suggested inert gases as alternatives. METHODS We studied the cardiopulmonary responses to intravenous infusion of carbon dioxide, nitrous oxide, argon, helium, and(More)
"Twinning" refers to a constructive partnership between hospitals in developed and developing nations. Such an effort may contribute immensely to capacity building for the developing nation, but one of the reasons given for the lack of sustainability is cost. We share a detailed operating cost analysis of our recent experience with an institution in(More)
Small-volume hypertonic resuscitation has been proposed as an effective means for restoration of cardiovascular function after hemorrhage at the scene of an accident. We evaluated the cardiovascular, metabolic, and neurohumoral response of resuscitation after hemorrhage using 200 ml of 2400 mosm sodium chloride, 6% dextran 70. Unanesthetized adult sheep(More)

PATIENTS One hundred thirty-six patients from 1982 to 1994. INTERVENTION Diversion followed by resection and ostomy closure for gastrointestinal fistulas, pancreaticojejunostomy for(More)
HYPOTHESIS Despite advances in preoperative radiologic imaging, a significant fraction of potentially resectable pancreatic cancers are found to be unresectable at laparotomy. We tested the hypothesis that preoperative serum levels of CA19-9 (cancer antigen) and carcinoembryonic antigen will identify patients with unresectable pancreatic cancer despite(More)
BACKGROUND Laparoscopic Roux-en-Y gastric bypass (GBP) has been previously described, but a comparative study between laparoscopic and open GBP has not been reported. The purpose of this study was to compare surgical outcomes oflaparoscopic GBP with those of open GBP for treatment of morbid obesity. STUDY DESIGN From August 1998 to September 1999, we(More)
