[Endoscopic treatment of residual lithiasis. 661 cases]

Endoscopic sphincterotomy is a well-established procedure for treating choledocolithiasis and particularly residual lithiasis. The aim of this study is to expose our experience with this method and to evaluate his safety and efficacy.

It is a retrospectively collected series of 661 patients with residual choledocolithiasis.

Endoscopic retrograde cholangio-pancreatographies were performed in 651 patients (98.5%). Standard sphincterotomy was realized in 633 patients (95%) and a pre-cut technique was done in 15 (2%). Bile duct clearance was achieved in 583 cases (91%). Overall, the complication rate of sphincterotomy was about 8.4%.

Endoscopic sphincterotomy is a safe and effective procedure for patients with residual choledocolithiasis.
