Laparoscopic common duct exploration in the management of choledocholithiasis.

BACKGROUND: Optimal treatment strategies for addressing common duct stones at laparoscopic cholecystectomy remain controversial. The study presents the authors' experience with laparoscopic common bile duct exploration (LCBDE). METHODS: A retrospective review was performed of 71 LCBDEs performed over 5 years using either transcystic duct flushing and mechanical techniques, transcystic duct basket retreival techniques, or laparoscopic choledochotomy. RESULTS: Laparoscopic CBDE resulted in ductal clearance in 61 of 71 (85%) cases with only 1 case of unsuspected retained common duct stones and only 1 major complication. Review of the cases that did not result in common duct clearance suggests that the success rate of laparoscopic CBDE could be increased. CONCLUSIONS: Laparoscopic CBDE is an effective treatment for concurrent gallstones and common duct stones and avoids the potential morbidity of an endoscopic sphincterotomy. General surgeons with adequate training and experience can perform laparoscopic CBDE safely and effectively.

Choledocholithiasis associated with malignant biliary obstruction--significance and management.

Distal bile duct stones and proximal extra-hepatic malignant biliary obstructions may coexist. These stones, probably predating the development of the malignant obstruction but of unknown aetiological significance, were found in seven of 60 patients with proximal tumours (11.6%) at percutaneous biliary drainage. In two of these cases, stones blocked outflow from a supra-ampullary stent. All seven patients also had evidence of gall-bladder stones. Five of the seven patients had cholangiocarcinoma, giving an incidence of duct stones in such patients (n = 27) of 18.5%. In one case, the stones were removed endoscopically, in four, the stones were removed percutaneously and, in the remaining two cases, they were left in situ beside a stent. None of 120 cases with malignant obstruction had stones proximal to the obstruction. Distal common duct stones are associated with proximal malignant biliary duct obstruction, especially with cholangiocarcinoma and coexisting gall-bladder stones. They may interfere with stent function and cause diagnostic confusion at cholangiography.

Long-term results (7 to 10 years) of endoscopic papillotomy for choledocholithiasis. Multivariate analysis of prognostic factors for the recurrence of biliary symptoms.

BACKGROUND: The long-term outcome after endoscopic papillotomy is poorly defined. The aim of this study was to determine the long-term results of this method in the treatment of common duct calculi and to determine which prognostic factors are associated with the relapse of biliary symptoms. METHODS: Between 1985 and 1988, 223 consecutive (149 women, mean age 67.9 years) patients underwent endoscopic papillotomy for duct stones; 127 had already undergone cholecystectomy or underwent this operation during the same hospitalization. Follow-up data were obtained retrospectively from the patients and patients' relatives and general practitioners. RESULTS: The procedure was successful in 217 of 223 cases (97%), of which 203 were followed-up; 2 patients died in the first month after treatment (0.89%). Mean follow-up for the 201 patients was 6.2 years, during which 31 relapsed (15%). Three significant prognostic factors for late complications were identified in a multivariate analysis. The recurrence rate of biliary symptoms in patients who were left with an in situ gallbladder was 20.2%, and 11% for those whose gallbladder was removed (p = 0.04). Patients with a bile duct 15 mm or greater in diameter were more prone to recurrence of symptoms than those with a bile duct 10 mm or less in diameter (41% vs. 10%, p = 0.025) and were especially at higher risk to develop recurrent stones (19.5% vs. 4.9%, p = 0.019). Stone recurrence, but not biliary symptoms as a whole, was more frequent in patients with a peripapillary diverticulum (p = 0.035). CONCLUSIONS: The long-term results of endoscopic papillotomy are comparable with those of surgical techniques. The prognostic factors associated with relapse of biliary symptoms as a whole are gallbladder left in situ and choledochal diameter. Bile duct size and peripapillary diverticula are associated with recurrent bile duct stones.
