Reoperation of biliary tract by laparoscopy: a consecutive series of 26 cases

In the past, previous operation of biliary tract represented a contraindication to perform reoperation by laparoscopy. As experience with laparoscopic techniques and instrumentation has expanded, reoperation of biliary tract with laparoscope has become an accepted procedure in the management of cholelithiasis. We present our interesting experience with regard to reoperation of biliary tract by laparoscopy.

Laparoscopic operation of biliary tract was performed on 3,674 consecutive patients from April, 1992 till June, 2005. Among these patients, 26 had a previous open operation of biliary tract and their clinical data were retrospectively analyzed as follows: seven cases had complicated intrahepatic bile duct stones (restricted at hepatic duct of the first and second order). Diameter of common bile duct in patients with common duct stones was above 1.2 cm, the number of stones for each patient was more than 3 and all the biggest stones exceeded 1 cm. In the 26 patients, preoperatively, stenosis of bile duct and malignant tumour were excluded by both radiological examination and detection of serological tumour markers.

The mean operative time was 125 min (75-190 min). Reoperations of biliary tract by laparoscope were successfully accomplished in 25 patients. One patient was converted to open operation and the common duct stones were removed by right angle forceps through short incision. None of the patients developed any severe complication, all of them recovered and were successfully discharged. Three cases with retained calculuses were successfully cured by removing these through the sinus tract of T tube.

Laparoscopic procedure is minimally invasive, safe and feasible for laparoscopic experts in case of reoperation of biliary tract. It is also a first method for patients for whom endoscopic sphincterotomy is contraindicated.
