Background and Aims: Enteroscopy-assisted ERCP is challenging in patients with surgically altered upper GI anatomy. This study evaluated a novel procedure, EUS-directed transenteric ERCP (EDEE), in the de novo creation of an enteroenteric anastomosis for the performance of ERCP in non-Roux-en Y gastric bypass (RYGB) patients. Methods: This was a multicenter retrospective study involving 7 centers between January 2014 and October 2018. Primary outcome was clinical success (completion of EDEE and ERCP with intended interventions), and secondary outcomes were technical success and rate/severity of adverse events. Results: Eighteen patients (mean age, 63 years; 13 women) were included. The most common type of surgical anatomy was Whipple (10/18) and Roux-en-Y hepaticojejunostomy (6/18). Technical success rate of EUS-guided lumenapposing metal stent (LAMS) placement was 100% and of ERCP was 94.44% (17/18). Fourteen patients underwent separate-session EDEE with a median of 21 days (interquartile range [IQR] , 11.5-36) between the 2 procedures. Median total procedure time was 111 minutes (IQR, 81-192). Clinical success and adverse events occurred in 17 (94.4%) and 1 (5.6%; abdominal pain) patients, respectively, during a median follow-up of 88 days (IQR, 54-142). Conclusions: This study suggests that EDEE using LAMSs is feasible and safe in patients with non-RYGB surgical anatomy and complex pancreaticobiliary pathologies.
