Suturing a 20-mm lumen-apposing metal stent allows for safe same-session EUS-directed transgastric intervention in patients with Roux-en-Y gastric bypass anatomy: a multicenter study (with video)

      Background and Aims

      EUS-directed transgastric intervention (EDGI) is an established technique for the management of pancreaticobiliary pathology in Roux-en-Y gastric bypass (RYGB) patients. There is an inherent risk of intraprocedural stent dislodgement, leading to perforation. The procedure is therefore often performed in 2 stages, 2 to 4 weeks apart, to allow for fistula maturation to mitigate the risk of lumen-apposing metal stent (LAMS) dislodgment. However, some clinical indications such as cholangitis require more urgent intervention, rendering this approach impractical. The aim of this study was to evaluate the safety and efficacy of same-session (SS)-EDGI with fixation of a 20-mm LAMS using endoscopic suturing.

      Methods

      This was a 2-center, retrospective study of consecutive RYGB patients who underwent SS-EDGI using a sutured 20-mm LAMS between February 2018 and May 2020. Patient demographics, procedural details, and clinical outcomes were recorded.

      Results

      Thirty-seven patients (mean age, 58.1 years; 86.5% women) underwent SS-EDGI with a median follow-up of 31.8 months. The procedural intervention was ERCP in 33 patients (89.2%) and ERCP with EUS in 4 patients (10.8%). Technical success was 100%. Access was achieved through the gastrogastric fistula in 26 patients (70.3%) and the jejunogastric fistula in 11 (29.7%). The LAMS was anchored with 2 endoscopic sutures in 33 patients (89.2%) and 1 suture in 4 (10.8%). Adverse events occurred in 4 patients (10.8%; 3 postprocedural bleeding, 1 cholangitis). There were no episodes of stent dislodgement or delayed stent migration. A persistent fistula was diagnosed in 7 patients (18.9%) who underwent objective testing (n = 28, 75.7%), of which 6 were successfully closed endoscopically.

      Conclusions

      Single-stage EDGI using a sutured 20-mm LAMS was associated with a high rate of technical success, low rates of adverse events, and no episodes of stent migration. Persistent fistulas, although common, were amenable to endoscopic management.
