In a group of 23 patients with suspected malignant disease in the abdominal cavity laparoscopy was indicated and 11 times positive findings were obtained--six time a primary tumourous process and five times secondaries. The authors demonstrate on case-histories the advantages of laparoscopy when other examination fail or give dubious results. In their group of patients it always helped to establish a definite diagnosis.
The incidence of bile leaks increased with the introduction of laparoscopic cholecystectomy in surgery. The present paper is focused on biliary leaks-their diagnosis and treatment in a large group of patients, with special emphasis on a miniinvasive approach. Nine biliary leaks were found (i.e. 0.72%). Four leaks resolved spontaneously, five were treated surgically with good results.

The authors describe, based on an analysis of 2970 patients subjected to endoscopy, the advantages of urgent endoscopy performed within six hours after admission to the surgical department. They refute former statements that urgent endoscopy is endoscopy performed within 24 or 48 hours. They discuss the different approach of endoscopists to different types of haemorrhage and to the time factor and emphasize the prognostic considerations of the endoscopist.
Recurrent ulcer is serious complication of surgical treatment. Resection, reconstructive operations under conditions of severe adhesions, inflammatory infiltrates and abscesses are exacting and often connected with complication. In the period of 1978-1987 the authors carried out 64 reoperations for recurrent peptic ulcer, incl. 39 cases, whom they had to operate urgently. 19 patients were reoperated on account of penetration and peroperation of the ulcer, 11 because of massive haemorrhage, and 9 patients because of gastrocolic fistulae. In reoperations, subtotal resection of the stomach with vagotomy was carried out in 66%. In 4 patients reoperated repeatedly, Zollinger-Ellison's syndrome was found and resection of the pancreas was performed simultaneously. The mortality rate in the group, including patients reoperated urgently, was 21.9% (i.e. 14). The authors emphasize that the main aim of reoperation must be long-term therapeutic results without recurrences of ulcers and without serious functional disturbances.
The incidence of bile leaks has increased with the advent of laparoscopic cholecystectomy. The present paper is focused on bile leaks--their diagnosis and management approaches with special consideration to relaparoscopy. From February 1992 to May 1995 a total of 1223 laparoscopic cholecystectomies were performed in two hospitals. Eight biliary leaks were found in the series under study (i.e. 0.65%). The diagnosis was confirmed by means of ultrasound, CT scans and ERCP. Three leaks resolved spontaneously on external drains placed during the operation. Two and three patients underwent laparotomy and relaparoscopy, respectively. The etiology of the leakage included three cases of ducts of Luschka, one cystic duct leak, and one retained CBD stone. the source of the remaining leaks was not determined. In all cases the management approaches comprised relaparoscopy and laparotomy. It may be concluded that an early diagnosis and management of bile leaks after laparoscopic cholecystectomies would prevent further complications.
Laparoscopic cholecystectomy is an accepted part of the training of surgical residents at present. Further procedures performed by residents include laparoscopic appendectomy, herniorrhaphy and others. This report analyzes the first 22 months of operative laparoscopy in Bakes Surgical Hospital and the impact on the training of residents. From September 1993 through May 1995 four residents performed 179 laparoscopic operations. Their operative experience has been shifted especially towards laparoscopic cholecystectomy but education in open cholecystectomy and open biliary tract procedures has not been jeopardized. It may be concluded that surgical residents can master essential laparoscopic operations without additional complications in a manner standard for training of other procedures.
