Endoscopic sphincterotomy for retained common bile duct stones in patients with T-tube in situ in the early postoperative period

We report on thirty-nine patients who underwent endoscopic sphincterotomy (ES) and stone extraction for retained common bile duct calculi with a T-tube in situ. Sixteen of the patients had undergone unsuccessful attempts at removal by flushing or dissolution by cholesterol solvents. A total of 76 stones were present: 53 distal to the T-tube and 23 proximal to the T-tube. ES and clearance of the common bile duct was achieved in 37 patients (95 per cent) and complications occurred in three patients (7.7 per cent). This method is an effective and relatively safe method in the early postoperative period allowing rapid treatment during the same admission as for the original operation and early hospital discharge.
