BACKGROUND: The efficacy and safety of peroral direct cholangioscopy (PDCS) in patients with surgically altered anatomy (SAA) are unclear. The present study aimed to evaluate the efficacy and safety of short-type single balloon enteroscope (s-SBE)-assisted PDCS using an ultra-slim endoscope in patients with SAA.
MATERIALS AND METHODS: We retrospectively analyzed 12 sessions of PDCS performed in 8 patients with surgically altered gastrointestinal or pancreatobiliary anatomy between November 2017 and September 2019 at our institution. Endoscopic retrograde cholangiopancreatography using s-SBE was initially performed. Subsequently, the s-SBE was exchanged for an ultra-slim endoscope through an overtube with an inflated balloon to perform PDCS. We analyzed the success rates and adverse events resulting from the procedure.
RESULTS: Six patients had biliary stones and 2 had biliary strictures. The types of reconstruction were Roux-en-Y choledochojejunostomy (n=5), Billroth II gastrectomy (n=2), and Roux-en-Y gastrectomy (n=1). Biliary insertion of the ultra-slim endoscope was successful in all 12 sessions. Biliary interventions included electronic hydraulic lithotripsy in 5 sessions, stone removal using basket catheter in 3 sessions, biopsy in 2 sessions, and diagnosis of no residual stones in 2 sessions. Complete stone removal was finally achieved in all 6 patients with biliary stones. Biliary strictures in 2 patients were diagnosed as adenocarcinoma following a biopsy. The adverse events were cholangitis of mild severity in 3 sessions.
CONCLUSION: S-SBE-assisted PDCS using an ultra-slim endoscope was useful and safe in patients with SAA, although care should be taken to avoid adverse events.
