Outcomes of minor versus major papilla rendez-vous for EUS-guided pancreatic duct drainage

Abstract

ObjectivesEUS-guided pancreatic duct drainage (EUS-PD) using rendez-vous has been suggested as a safer alternative to pancreatogastrostomy. Fibrostenotic disease in the pancreatic head may however preclude major papilla rendez-vous, leading to preferential guidewire advancement through the minor papilla. Our aim was to compare the outcomes of minor and major papilla rendez-vous. MethodsThis is a tertiary single-center retrospective analysis of all consecutive EUS-PD procedures performed from 2015 to April 2022. EUS-PD was only performed following failed retrograde attempts. Successful EUS-PD rendez-vous cases were included and minor and major papilla procedures were compared. ResultsThirty-three patients were included in the final analysis (66.6% male, mean age 56.1 [SD±14.8] years, 54.6% active smokers). In 21 patients (63.6%), minor papilla rendez-vous was attained. Clinical success was achieved in 81.0% vs. 58.3% in the major papilla group (p = 0.230). The overall incidence of AE was similar in both groups (9 [42.9%] vs. 4 [33.3%] events, p = 0.719), with a comparable distribution in severe, moderate and mild AE. Incidence of recurrent pancreatitis was almost identical (28.6% vs. 25.0%, p = 1.000). ConclusionsFor patients with symptomatic chronic pancreatitis, EUS-PD using minor or major papilla rendez-vous attained similar results, suggesting that pancreatic duct drainage through the minor papilla can be considered as equally effective.
