| Abstract: | BACKGROUND Bilioenteric Roux-en-Y anastomosis is one of the most complicated approaches for reconstructing the gastrointestinal tract, and endoscopic retrograde cholangiopancreatography(ERCP) is technically challenging in patients after bilioenteric Roux-en-Y anastomosis. The optimal endoscopic strategies for such cases remain unknown.AIM To explore the feasibility and effectiveness of single balloon enteroscopy-assisted(SBE-assisted) therapeutic ERCP in patients after bilioenteric Roux-en-Y anastomosis based on multi-disciplinary collaboration between endoscopists and surgeons as well as report the experience from China.METHODS This is a single center retrospective study. All of the SBE-assisted therapeutic ERCP procedures were performed by the collaboration between endoscopists and surgeons. The operation time, success rate, and complication rate were calculated.RESULTS Forty-six patients received a total of 64 SBE-assisted therapeutic ERCP procedures, with successful scope intubation in 60(93.8%) cases and successful diagnosis in 59(92.2%). All successfully diagnosed cases received successful therapy. None of the cases had perforation or bleeding during or after operation,and no post-ERCP pancreatitis occurred.CONCLUSION Based on multi-disciplinary collaboration, SBE-assisted therapeutic ERCP in patients after bilioenteric Roux-en-Y anastomosis is relatively safe and effective and has a high success rate. |
