Efficacy and safety of double-balloon endoscopy-assisted endoscopic papillary large-balloon dilatation for common bile duct stone removal.

Abstract

BACKGROUND Endoscopic retrograde cholangiopancreatography is difficult to perform in patients with gastrointestinal tract reconstruction. AIMS To evaluate the efficacy and safety of double-balloon endoscopy-assisted endoscopic papillary large-balloon dilatation for common bile duct stones in patients with gastrointestinal tract reconstruction. METHODS We conducted a retrospective case series with a comparison to historical controls. During the period 2009-2013, 11 postoperative patients underwent endoscopic papillary large-balloon dilatation (Group A). Procedure efficacy and safety were compared with patients who underwent endoscopic sphincterotomy without endoscopic papillary large-balloon dilatation, who served as historical controls (Group B). RESULTS Group A consisted of 11 patients (63.6% males, mean age 78±10 years), and Group B consisted of 32 patients (78.1% males, mean age 75±7 years). The stone clearance rate was significantly higher in Group A than in Group B (100% vs. 65.6%, respectively; p<0.05). Median procedure time was significantly shorter in Group A than in Group B (54min vs. 102min, respectively; p<0.05), and the complication rate was not significantly different between groups (18% vs. 15.6%, respectively; p=0.586). CONCLUSION Endoscopic papillary large-balloon dilatation may be an effective and safe treatment procedure in patients with gastrointestinal tract reconstruction.
