Laparoscopic transcystic management of choledocholithiasis.
Our objective was to review our community hospital experience with laparoscopic management of choledocholithiasis from 1991 to 1997. We performed a retrospective review of all case records of patients with choledocholithiasis managed surgically at St. Francis Hospital during the study period. Data regarding the history, presentation, investigations, operative details, and follow-up were recorded. Procedures were performed by multiple attending surgeons supervising surgical residents. All common bile duct explorations (CBDEs) were performed by a transcystic approach and followed routine cholangiography. In most cases, cystic duct dilatation over a guide wire was followed by transcystic CBDE with choledochoscopy. Stone extraction was accomplished through a combination of flushing, basket manipulation, fragmentation, retrieval, or advancement of stones through the ampulla. Data were analyzed using SPSS computer software, and P < 0.05 was considered statistically significant. During the period of study there were 1053 laparoscopic cholecystectomies with and without cholangiography and 100 total CBDE performed. Of these, 54/100 had an attempt at laparoscopic CBDE. There were 39 females and 15 males, with a median age of 52 years (range 14-88). Presentation included acute cholecystitis or biliary colic (63%), gallstone pancreatitis (20%), and jaundice or cholangitis (17%). Successful laparoscopic stone removal was achieved in 36 of 54 (67%) cases. Eighteen of the remainder (33%) were converted to an open procedure. Size, number, position of stones, technical difficulties in accessing the common bile duct, and patient factors contributed to open conversion. The rate of successful laparoscopic CBDE improved for each individual surgeon from an average of 22 per cent in the first half of the study period (1991-1994) to 87 per cent in the second half (1995-1997). There was no operative mortality. Significant morbidity in the laparoscopic group included one retained stone and two cases of postoperative pancreatitis. There were three false negative preoperative endoscopic retrograde cholangiopancreatography examinations. Multivariate analysis showed that experience of the individual surgeon was the only significant factor predicting successful laparoscopic CBDE. Low initial success rate in the early phase of the study period improved dramatically to reach an overall success rate of 87 per cent in the second half. Laparoscopic management of common bile duct stones is possible in a community setting with a high success rate and minimal morbidity. It precludes excessive use of endoscopic retrograde cholangiopancreatography with its own set of complications but is associated with a significant learning curve. It is currently our preferred therapeutic approach for choledocholithiasis discovered pre- or intraoperatively.
