Since the first laparoscopic common bile duct exploration in Hungary published in 1999 the authors use the technique themselves. We review and analyse our activity between 1 June 1999 and 31 August 2003. The minimally invasive approach was selected in twelve patients with obstructive jaundice for suspected bile duct stones. Eight of these patients underwent preoperative endoscopy, but either the number and/or size of stones or various complications prevented successful endoscopic stone extraction; five sphincterotomies--two followed by stenting--were performed. The four other patients did not consent to endoscopy. During surgery the biliary tract was visualised by choledochoscope (a bile duct endoscope with video connection) in four cases via the distended cystic duct and in eight cases via longitudinal choledochotomy. In one case there was no occlusion at all, in another one dilatation was performed because of a structure. In nine patients stones were removed either through the choledochotomy/cystic duct or by passing them into the duodenum. In one patient we converted to open procedure due to a stone impacted in the papilla of Vater. After choledochotomy intracorporal suturing and knot tying techniques were used to close the incision. On six occasions a cystic drain, three occasions a T-tube and on three occasions primary closure was used. Two bile leaks were treated by endoscopic stenting and in one patient a laparotomy was needed. There was no mortality. We believe that laparoscopic common bile duct exploration can be successful even in complicated situations.
