Treatment of common bile duct injuries during laparoscopic cholecystectomy: endoscopic and surgical management.

The increase of laparoscopic cholecystectomy has resulted in an increase of bile duct injuries. The purpose of this article is to define the types of injury, their occurrence and frequency, and their management by endoscopic and surgical techniques. Three investigations were included in the present study.

Laparoscopic highly selective vagotomy: technical considerations and preliminary results in 119 patients with duodenal ulcer or gastroesophageal reflux disease.

There were 33 with duodenal ulcers, 31 with duodenal ulcers plus gastroesophageal reflux, and 55 with gastroesophageal reflux. Operating time varied from 120 to 160 minutes.

[Laparoscopic cholecystectomy. 1203 cases with ultraselective cholangiography].

We present our experience at the University of Chile Hospital with 1203 cases of laparoscopic cholecistectomy between April 1991 and July 1993. In only 36 patients ultraselective cholangiography was performed. In 88 cases an endoscopic cholangiography was performed prior to surgery because of suspicion of choledocolithiasis.
