The management of common bile duct calculi by endoscopic sphincterotomy in patients with gallbladders in situ.

Overview

Endoscopic sphincterotomy (ES) is widely used in the treatment of patients with common bile duct (CBD) stones following cholecystectomy. The technique has now been extended to patients with gallbladders still present and the results of ES in 100 such patients is reported. Fifty-nine were considered unsuitable for surgery (Group A), in 38 ES was performed as a preliminary to cholecystectomy (Group B) and in 3 ES was performed following emergency cholecystostomy (Group C). ES was achieved in 98 patients and stones completely extracted in 91 patients. In Group A 5 patients required surgery, in 3 because of technical failure and in 2 because of empyema of the gallbladder. One patient who presented in extremis died following failure to extract a large CBD stone. On follow-up (4-50 months), 16 patients have died but in only one from gallbladder sepsis, and one has had a cholecystectomy for pain. In Group B choledochotomy was avoided in 29 of the 37 patients who agreed to cholecystectomy. In Group C no further surgery was required and all patients in Groups B and C remain well. These results indicate that ES is an effective technique for treating patients with CBD stones with the gallbladder in situ, either alone in patients considered unsuitable for surgery or as an adjunct to surgery.
