Despite its relative safety (in comparison with surgery), and undoubted role in many clinical circumstances, biliary sphincterotomy is the most dangerous procedure routinely performed by endoscopists. Complications occur in about 10% of patients; 2 to 3% have a prolonged hospital stay, with a risk of dying. This document is an attempt to provide guidelines(More)
BACKGROUND The role of nitric oxide (NO) in ischemia reperfusion (I/R) injury is controversial as both beneficial and harmful effects have been reported. We explored the potential role of a pharmacological agent recently shown to generate NO metabolically in the liver in an animal model of transplantation. METHODS The effect of a selective hepatic NO(More)
OBJECTIVE To review the history, development, and current applications of robotics in surgery. BACKGROUND Surgical robotics is a new technology that holds significant promise. Robotic surgery is often heralded as the new revolution, and it is one of the most talked about subjects in surgery today. Up to this point in time, however, the drive to develop(More)
BACKGROUND Radiation therapy as an adjunct to surgery for rectal cancer has been shown to reduce local recurrence but has not improved survival. In a previous study, combined radiation and chemotherapy improved survival significantly as compared with surgery alone, but not as compared with adjuvant radiation, which many regard as standard therapy. We(More)
OBJECTIVE The authors evaluated the morbidity, mortality, and quality of life after pancreatic debridement for necrosis and compared these values to those for quality of life after elective medical and surgical management for chronic pancreatitis. SUMMARY BACKGROUND DATA Quality of life after pancreatic debridement for necrosis has received little(More)
Twelve children underwent elective laparoscopic cholecystectomy for symptomatic cholelithiasis during a 10-month period in one institution. The operative technique that has been described for adults was modified because of the smaller dimensions of pediatric patients. These modifications are discussed in this report, as are new alternatives for evaluating(More)
A hepatic adenoma (HA) nearly isointense to normal liver on short and long repetition and echo time spin echo pulse sequences is presented. Contrary to previous expectations, the case shows that a single hepatic mass with these signal characteristics on magnetic resonance without a scar may represent either HA or focal nodular hyperplasia.
PURPOSE To retrospectively determine the sensitivity and specificity of magnetic resonance (MR) imaging findings in patients with clinical athletic pubalgia, with either surgical or physical examination findings as the reference standard. MATERIALS AND METHODS Institutional review board approval was granted for this HIPAA-compliant study, and informed(More)
Laparoscopic cholecystectomy has become the procedure of choice for surgical removal of the gallbladder. The most significant complication of this new technique is injury to the bile duct. Twelve cases of bile duct injury during laparoscopic cholecystectomy were reviewed. Eight injuries were of a classic type: misidentification of the common duct for the(More)
