Aim: To evaluate the efficacy of balloon enteroscope for therapeutic ERCP for choledocolothiasis in patients with Roux-en-Y (R-Y) anastomosis.
Patients and Methods: Thirty-nine patients with choledocolitiasis with R-Y anastomosis between October 2005 and August 2013 were included in this study. Single balloon enteroscopy (SBE: working length of 2000mm, working channel of 2.8mm), short double balloon enteroscopy (Short DBE: working length of 1520mm, working channel of 2.8mm), and short SBE (working length of 1520mm, working channel of 3.2mm) were used in 9,7, and 23 patients, respectively. The success rate of reaching the major papilla, the technical success rate, and the complication rate were retrospectively evaluated.
Results: The success rate of reaching the major papilla was 85% (33/39), and which of SBE, short DBE and short SBE were 56% (5/9), 71% (5/7) and 100% (23/23), respectively. The overall technical success rate was 74% (29/39), and which of SBE, short DBE, short SBE were 33% (3/9), 71% (5/7), 91% (21/23), respectively. The complication rate was 15% (n = 6: cholangitis 3, mild pancreatitis 2, aspiration pneumonitis 1), and all complications were managed conservatively.
Conclusion: Therapeutic ERCP using a short SBE for choledocolitiasis in patients with R-Y anatomy was considered to be safe and effective.
