Aim: 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.
Methodology: It is a retrospectively collected series of 661 patients with residual choledocolithiasis.
Results: 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%.
Conclusion: Endoscopic sphincterotomy is a safe and effective procedure for patients with residual choledocolithiasis.
