OBJECTIVE: To evaluate the feasibility, effectiveness and safety of a new snare-assisted peroral direct choledochoscopy/pancreatoscopy (PDCPS) technique.
METHODS: From November 2014 through December 2016, 20 consecutive patients with indications for PDCPS were enrolled in this observational study. Endoscopic retrograde cholangiography was initially performed using a conventional duodenoscope, and endoscopic papillary balloon dilation was performed. Next, an ultra-slim endoscope was inserted to perform the PDCPS; a snare tightened around the end of the scope's bending section facilitated its entry into the common bile duct (CBD). The primary endpoint was the overall success rate of the PDCPS procedure (successful biliary intubation and visualization of the area of interest) and the time for biliary intubation with the ultra-slim upper endoscope.
RESULTS: Participants (11 men and 9 women; mean age, 72.2 years [range, 41-93 years]) had CBD adenoma (n=1), large CBD stones after failed extraction/lithotripsy treatment (n=13), CBD strictures (n=4), pancreatic duct tumor (n=1) or pancreatic duct dilation (n=1). The success rate was 95%. The mean intubation time was 18min (range, 4-57min). No adverse events were reported.
CONCLUSIONS: A snare-assisted PDCPS technique appears to be technically feasible, effective and safe for both diagnostic and therapeutic applications.
