BACKGROUND/AIMS The aim of this study was to ascertain the therapeutic efficacy of percutaneous cholecystostomy in a selected group of high-risk patients who were physiologically unable to tolerate an open procedure. METHODOLOGY We reviewed the hospital records of 11 critically ill patients who underwent percutaneous cholecystostomy for acute(More)
The rarity of bullet emboli leads to frequent delays in diagnosis and inadequate early management. Our recent experience with this entity is described, and 153 cases reported in the English-language literature are reviewed and summarized. The majority of cases occurs as a consequence of civilian violence among men in their 20s and 30s. Most bullet emboli(More)
OBJECTIVE To analyze the preliminary experience with the new da Vinci single-site technology for cholecystectomy. HYPOTHESIS Single-incision laparoscopic cholecystectomy is technically challenging and a related learning curve clearly exists. A novel approved robotic single-port platform has recently been introduced. This technology may help overcome some(More)
The objective of this study was to find the incidence of accidental exposures to blood and body fluids among surgeons during operations and to describe their dynamics. A probabilistic model was also used to predict the cumulative 30-year risk to the surgeon of contracting hepatitis B and C viruses (HBV, HCV) or human immunodeficiency virus (HIV) infection(More)
BACKGROUND This study compared long-term survival in pancreatic or periampullary cancer treated with Whipple pancreatoduodenectomy (PD) and pylorus-preserving pancreatoduodenectomy (PPPD). METHODS Two hundred twenty-one patients with pancreatic head or periampullary cancer were treated. Prognostic variables included age, gender, type and period of(More)
BACKGROUND Laparoscopic low anterior resection for rectal cancer has never gained wide acceptance among general surgeons, mainly due to the technical difficulties encountered during pelvic dissection. It has therefore been stated that these patients should undergo open rather than laparoscopic surgery. Hand-assisted laparoscopic surgery (HALS) is a new(More)
The occurrence of thrombosis in the portal system is an underappreciated complication of splenectomy. Presenting symptoms are usually mild and nonspecific. The short hospital stay associated with the laparoscopic approach could delay the early diagnosis of this condition unless routine imaging controls are planned after discharge. The records of 40 patients(More)
OBJECTIVE/BACKGROUND The GONO-FOLFOXIRI regimen improved the rate of R0 secondary resection of metastases in initially unresectable metastatic colorectal cancer. The objective of this study was to evaluate the long-term outcome of resected patients and the impact of FOLFOXIRI on perioperative morbidities, mortality, and chemotherapy induced hepatotoxicity.(More)
Between 1946 and 1987, 647 patients with periampullary tumors were diagnosed at the University of Chicago Medical Center. These included 549 tumors located in the head of the pancreas, 40 in the distal common bile duct, 29 in the duodenum, and 29 at the ampulla of Vater. Ninety-eight per cent of all tumors were adenocarcinoma, with 93% of the remaining(More)
The natural history and appropriate treatment of giant liver haemangioma remain poorly defined. The diagnostic strategy and the results of a longitudinal study of 78 such lesions are described. Sixteen resected patients and 62 with asymptomatic giant haemangiomas were entered into a follow-up programme consisting of clinical assessment and abdominal(More)
