Özet
Background Biliary cannulation can be challenging even for expert endoscopists, and rescue techniques are limited. Our objective was to determine the feasibility and safety of partial ampullary endoscopic mucosal resection (PA-EMR), a novel technique for biliary cannulation. Methods Monocentric, retrospective analysis of a prospectively maintained database in a tertiary referral university hospital. Fourteen patients who required endoscopic retrograde cholangiopancreatography (ERCP) and underwent PA-EMR between January 1, 2020 and January 31, 2021 were included. For biliary cannulation of prominent papillae, PA-EMR was performed using a standard polypectomy snare, alone or in combination with needle-knife sphincterotomy. In patients with non-prominent papilla, the papillary mucosa was elevated with the aid of methylene blue injection before resection and combined with needle-knife fistulotomy when needed. The rate of technical success and adverse events was assessed. Results The bile duct cannulation success was 99% in the first attempt and 100% overall with the PA-EMR technique. Only one patient experienced mild bleeding, which spontaneously stopped. Conclusion PA-EMR is an effective technique that may be considered as a rescue technique for difficult biliary cannulation in expert hands. Future studies including larger cohorts and comparisons with other techniques are warranted to further confirm the feasibility and safety of this novel technique.
