Outcome of surgery for failed endoscopic extraction of common bile duct stones in elderly patients

Endoscopic sphincterotomy (ES) is the treatment of choice for common bile duct stones in elderly patients. For those in whom endoscopic clearance of the common bile duct fails the treatment options include stenting, dissolution therapy and lithotripsy. Surgery is often avoided because of the reported high morbidity and mortality in elderly patients. We have reviewed the outcome of patients referred for surgery after failed endoscopic clearance of common bile duct stones. Over a 3-year period, 100 patients with common bile duct stones were referred specifically for endoscopic clearance of the common bile duct (median age 69 years, range 19-97 years). In seven patients duct clearance was possible without ES and in five patients ES was considered inappropriate. ES was attempted in 88 patients and was successful in 75 (85%). Of the 13 patients failing ES or stone removal, surgery was performed in nine and four were stented. Of patients having successful ES (n = 75), ten were referred for surgery because of incomplete duct clearance. Surgery was performed to obtain duct clearance in 19 patients (eight male, 11 female, median age 77 years, range 47-90 years). Of the 19, eight had previously undergone a cholecystectomy (42%) and 17 of the 19 had biliary tract drainage preoperatively (90%). The procedures performed consisted of choledocholithotomy in all plus cholecystectomy (11), choledochoduodenostomy (7) and choledochojejunostomy (7). There were no deaths and only one major complication. The median total inpatient stay was 26 days (range 14-75 days) and the median postoperative stay was 12 days (range 7-50 days). We would conclude that open surgery can be performed safely and effectively in elderly patients with retained bile duct stones.
