Successful Intubation Using a Cap-Assisted Colonoscope for Endoscopic Retrograde Cholangiopancreatography in Patients Undergoing Roux-en-Y Reconstruction
Abstract
Endoscopic retrograde cholangiopancreatography (ERCP) is challenging in patients undergoing Roux-en-Y (REY) reconstruction; although balloon-assisted enteroscopy is the first-line treatment, it is not always available considering equipment and expertise. We aimed to evaluate the feasibility of using a cap-assisted colonoscope as the primary approach for ERCP in REY reconstruction. We included 47 patients with REY who underwent ERCP using a cap-assisted colonoscope between January 2017 and February 2022. The primary outcome was intubation success for ERCP using a cap-assisted colonoscope during REY reconstruction. The secondary outcomes were cannulation success, procedure-related adverse events, and variables affecting successful intubation. Comparing side-to-side jejunojejunostomy (SS-JJ) and side-to-end jejunojejunostomy (SE-JJ) groups, the intubation success rate using a cap-assisted colonoscope in the SS-JJ group was higher than that in the SE-JJ group (34 of 38 (89.5%) vs. 1 of 9 (11.1%), p p = 0.005). Usage of a cap-assisted colonoscope can be crucial for ERCP in patients undergoing REY reconstruction. Anatomically, SS-JJ can facilitate easy and accurate identification of the afferent limb and a highly successful ERCP using a cap-assisted colonoscope.
