Abstract
BACKGROUND AND AIMS: EUS-directed transgastric ERCP (EDGE) is an endoscopic modality for treating pancreaticobiliary disorders after Roux-en-Y gastric bypass. EDGE consists of EUS-directed gastrogastrostomy/jejunogastrostomy creation (EUS-GG; step 1), followed by transgastric ERCP (step 2). The two steps can be performed in the same or separate endoscopic session(s). Single-session EDGE is immediately therapeutic but risks perforation via LAMS dislodgement. Dual-session EDGE does not risk perforation, but the clinical malady festers during the 10-14-day interval required for fistula maturation. A "shortened-interval dual-session" EDGE (2-4 day interval) may resolve this dilemma. Our study compares 20-mm LAMS dislodgement risk between single-session and shortened-interval dual-session EDGE. METHODS: We conducted a single-center retrospective study of 21 RYGB patients who underwent EDGE using 20-mm LAMS by one advanced endoscopist between 3/2018 and 2/2020. Given the small sample size, a permutation of regressor residuals test was conducted to investigate the association between EDGE interval type and LAMS dislodgement, controlling for the effect of fistula type. RESULTS: Eleven patients (six female; mean age 55 years old) underwent single-session EDGE; LAMS dislodgement occurred in five cases (45%). Ten patients (eight female; mean age 60 years old) underwent shortened-interval dual-session EDGE (median interval 2 days); LAMS dislodgement occurred in one case (10%). The odds of LAMS dislodgement during single-session EDGE was 817% that of shortened-interval dual-session EDGE (OR 8.17; p = 0.05), after controlling for the effect of fistula type. CONCLUSIONS: Shortened-interval dual-session EDGE decreases the risk of intraprocedural 20-mm LAMS dislodgement while allowing for timely transgastric ERCP.
