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)
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)
Most recent reviews of pyogenic hepatic abscess emphasize percutaneous versus open surgical management and devote little time to studying the etiology or the clinical condition of the patient. In this study a detailed review was performed with a computerized analysis of multiple clinical parameters in 73 patients treated for pyogenic hepatic abscess during(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 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)
Groin injuries are common in athletes who participate in sports that require twisting at the waist, sudden and sharp changes in direction, and side-to-side ambulation. Such injuries frequently lead to debilitating pain and lost playing time, and they may be difficult to diagnose. Diagnostic confusion often arises from the complex anatomy and biomechanics of(More)
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)
OBJECTIVE The authors review studies relating to the immune responses evoked by laparoscopic surgery. SUMMARY BACKGROUND DATA Laparoscopic surgery has gained rapid acceptance based on clinical grounds. Patients benefit from faster recovery, decreased pain, and quicker return to normal activities. Only more recently have attempts been made to identify the(More)
BACKGROUND Liver metastases from breast cancer are associated with a poor prognosis (median survival < 6 months). A subgroup of these patients with no dissemination in other organs may benefit from surgery. Available data in the literature suggest that only in exceptional cases do these patients survive more than 2 years when given chemohormonal therapy or(More)
OBJECTIVE The purpose of this work was to determine the frequency and significance of characteristic nontumorous low attenuation defects found in the left hepatic lobe during CT arterial portography (CTAP). MATERIALS AND METHODS Eighty CTAPs performed over a 17 month period were retrospectively reviewed to identify nonsegmental low attenuation defects(More)
