The role of mesenteric angiography and embolization for massive gastroduodenal bleeding is unclear. We reviewed the records of patients who underwent angiography for acute, nonmalignant, and nonvariceal gastric or duodenal hemorrhage that was documented but not controlled by endoscopy. Fifty patients were identified over a 7-year period ending in March(More)
BACKGROUND Biliary cystadenomas and cystadenocarcinomas comprise 5% of cystic lesions in the liver. Cystadenomas are often incorrectly diagnosed as simple cysts, which results in inadequate therapy. Recurrence and possible malignant transformation are consequences of incomplete excision. Cystadenocarcinomas are very rare tumors that are felt to be(More)
Intention inference can be an essential step toward efficient humanrobot interaction. For this purpose, we propose the Intention-Driven Dynamics Model (IDDM) to probabilistically model the generative process of movements that are directed by the intention. The IDDM allows to infer the intention from observed movements using Bayes’ theorem. The IDDM(More)
Modern vehicles have become aware of safety hazards in their immediate surroundings detected by sensors and camera systems. Vehicle manufacturers are currently working on inter-connecting vehicles with wireless communication technologies, for that vehicles are able to exchange traffic safety related information. That way a vehicle could be warned about(More)
Although there are data in the literature about the safety and efficacy of laparoscopic liver resections, there are not many studies comparing laparoscopic versus open approaches in a case-matched design. The purpose of this study is to compare the perioperative outcome of laparoscopic versus open liver resections from a single institution. Thirty-one(More)
Data on 126 consecutive patients with periampullary tumors resected at the Cleveland Clinic between January 1950 and December 1984 were reviewed. One hundred five patients underwent pancreatoduodenal resection, 10 patients total pancreatectomy, and 11 patients local resection of the tumor. The site of tumor was ampulla of Vater (59), head of the pancreas(More)
The prevalence of angiographically proven coronary artery disease (CAD) in adults with end-stage liver disease who undergo evaluation for liver transplantation is unknown; also it is unclear if cholestatic liver disease represents an independent risk factor. Patients with end-stage liver disease over age 50 having liver transplantation were studied using(More)
Complications following pancreaticoduodenectomy are common, partly because of nutritional debilitation. The aim of this study was to evaluate the impact of early postoperative tube feeding on outcome of pancreaticoduodenectomy and determine the best method for delivering enteral feeding. A retrospective review of 180 consecutive patients undergoing Whipple(More)
BACKGROUND Many bile injuries are managed without referral to tertiary centers. Management of patients referred for a primary repair, or after a failed repair, was reviewed to compare outcomes. STUDY DESIGN Retrospective review of data collected in prospective database. RESULTS A total of 133 patients had been treated over 12 years ending in December(More)
BACKGROUND Major bile duct injuries remain a potentially devastating complication after laparoscopic cholecystectomy. A retrospective review was conducted of patients who underwent a biliary-enteric reconstruction of a biliary injury to assess their long-term outcome. METHODS Retrospective review of bile duct injury database from January 1990 to December(More)
