During 7057 conventional cholecystectomies (1972–1991), 16 bile duct injuries occurred, amounting to a risk of 0.22%. A total of 1022 laparoscopic cholecystectomies were performed without such a complication since April 1990. In a retrospective study, 64 patients (16 of our patients and 48 referrals) with an injury or stricture due to conventional(More)
Background: The postoperative development of benign colorectal anastomotic stricture remains a frequent and unsolved problem. Methods: From 1996 until 2002, we analyzed 94 consecutive patients with postoperative colorectal anastomotic stenosis who were treated endoscopically. Results: Sixty-eight patients were initially resected for malignant disease, and(More)
This is a report on 126 prospectively registered and controlled complications in 29,695 consecutive endoscopic procedures of the lower gastrointestinal tract. The overall complication rate is 0.4%. All endoscopic procedures were performed in our institution; no referrals “from other hospitals” are included. The therapy and prognosis of occurring(More)
BACKGROUND AND OBJECTIVE Diseases of the colon, especially cancer, are age-specific and thus occur more frequently in an aging population. Early diagnosis is prognostically decisive. Indications for coloscopy are often delayed in the elderly. It was the aim of this study to determine advantages and disadvantages of coloscopy in those aged over 80 years. (More)
We have investigated the application of near-infrared (NIR) fiber-optic spectroscopy for the diagnosis of pancreatic cancer. Cluster analysis of the Fourier transformed near-infrared (FTNIR) fiber-optic spectra of surgically resected pancreatic tumor tissues allowed discrimination of tumor from normal tissue with high sensitivity and specificity. The(More)
Blunt abdominal traumas with pancreatic injuries often cause partial or subtotal resection of the organ, especially when the pancreatic duct is damaged. A reconstructive method for anastomosis of the duct is reported in a case of a 9-year-old boy with complete pancreatic rupture in which the whole organ could be salvaged.
Background: In minimally invasive surgery intracorporal knot-tying is complicated by a limited field of vision and depth perception. Methods: The ``knot before loop'' technique aims to reduce intraabdominal movements in number and space needed. A grasping instrument 3 mm in diameter guides a slipfit hollow knot pusher with a notch to hold the thread, when(More)
BACKGROUND AND STUDY AIMS Intraluminal stenting of organs with stenoses or fistulae in anatomically difficult locations (for instance cardia, pylorus, large bowel), with a tendency to kinking or increased motility, still carries a high risk of stent dislocation. In the search for a solution, we report on the use of a new thermoplastic stent in animal(More)
