Background: In the present study we examined, in a meta-analysis of the literature, the contribution of intraoperative cholangiography (IOC) to incidence, type, and time of diagnosis of common bile duct (CBD) injuries during laparoscopic cholecystectomy (LC). Materials and methods: Forty of 2104 reports were enrolled for analysis. In 26 reports we found(More)
Stapled rectal mucosectomy (SRM) became a widely accepted surgical procedure for haemorrhoids. One of the rare complications is severe bleeding. We report the case of a patient who underwent SRM for thirddegree haemorrhoids. In addition, he suffered symptoms of outlet obstruction, although defecography showed no serious disease. One day after SRM, the(More)
Background: Submucosal and mucosal tumors of the stomach display a wide spectrum of histopathologic and prognostic characteristics. Biopsies obtained using endoscopic techniques often do not provide the representative histologic sample needed for further therapeutic decisions. Methods: From 1999 to 2002, 18 patients with gastric tumors underwent a combined(More)
Early gastric cancer (EGC) can present an indication for local resection procedures under pertain circumstances. Especially endoscopic mucosal resections (EMRs) and laparoscopic resections or those combined with endoscopy have been made possible in recent years. From 1996 to 2004, of a total of 425 patients with gastric cancer, 58 patients with EGC (13.6%)(More)
Anastomotic leakage is a serious complication in colorectal surgery, especially in the treatment of adenocarcinoma located in the left-sided colon and rectum. It is controversial whether anastomotic leakage is a prognostic factor for local recurrence and/or survival in this disease. To evaluate the impact of anastomotic dehiscence on the outcome of surgery(More)
Background: With the advent of laparoscopic cholecystectomy, the choice of procedure (laparoscopic vs open) and surgical management in gallstone disease are of interest. The purpose of this study was to examine the current approach and various strategies for cholecystectomy in Germany. Methods: A retrospective survey at 859 (of 1,200, 67.6 %) hospitals in(More)
Iatrogenic colonic perforation is a rare but very dangerous complication of colonoscopy. We report on eleven prospectivly recorded patients treated between 1994 and 1998. In seven cases the colonoscopy had been done for diagnostic and in four cases for therapeutic reason. Nine women and two men (age range 56 to 92 years) were affected. In 77 % the(More)
To ascertain whether preoperative short-term radiotherapy can improve local tumor control and the long-term survival of patients with operable rectal cancer, a prospective randomised trial was performed from 1988 to 1993. Ninety-three patients with rectal cancer were either directly treated with surgery (n = 46) or underwent preoperative radiotherapy with 5(More)
Gastric cysts are a rare disease and their diagnostic work-up often produces inconclusive results. We report on four gastric stromal tumors, in part huge, with cystic degeneration where the diagnosis and organ of origin remained unclear until operation. Considering these tumors as examples we discuss means and limits of differential diagnosis, taking into(More)
Cases of gallstone ileus (108) were analyzed retrospectively over 30 years. Even today, when laparoscopic cholecystectomy is done, the incidence of this rare disease remains the same. History, clinical and X-ray findings are non-specific. Aerobilia was seen in 17 % of the patients. Since 1992 sonography has proveded an exact diagnosis in 10 of 15 cases. In(More)
