Abstract

Background: Endoscopic drainage and necrosectomy are the preferred approaches in managing NP.We aimed to study clinical outcomes in NP managed with single or multiple lumen-apposing metal stents (LAMS) among patients treated with a primary endoscopic approach. Methods: This is a multicenter retrospective cohort study involving NP patients aged ≥18 who underwent either a single-gated (SG), single-gated converted to multi-gated (SG-MA), or multi-gated (MG) EUS-guided approach toWON drainage from 2021 to 2023. The study's primary outcome was determining clinical response (resolution of symptoms or no need for intervention 1 to 6 months after index diagnosis), and secondary outcomes included the number of procedures, adverse events, long-term complications, and mortality Results:We identified 107 patients with NP, of whom 95 (88.9%) were treated with a primary endoscopic approach; 75 (70.1%), 15 (14.0%), and 16 (15.0%) underwent SG, SG-MA, and MG approaches, respectively. The three study groups did not differ in demographic, clinical, or radiological characteristics. Technical success was 100%. Clinical success was 89.3%, 86.6%, and 87.5% with SG, SG-MG, and MG approaches, respectively (P = 0.94). An MG approach was associated with a lower number of necrosectomy sessions (mean difference, -3.82 sessions; P < 0.0001), days to LAMS removal (mean difference, -25.1 days; P = 0.049), and time to clinical response (mean difference, - 118.3 days; P = 0.04) than SG-MA approach. AnMG approach was associated with a lower need for percutaneous drainage (OR = 0.681; P = 0.002). The mortality rates were 13.3% (10/75), 7.1 % (1/14), and none (0/16) in the SG, SGMG, and MG groups, respectively (log-rank Mantel-Cox P = 0.242). There was no difference in AEs between the groups (P = 0.77) Conclusions: An MG approach to WON was safe and associated with earlier clinical response, fewer endoscopic necrosectomy procedures, and shorter LAMS dwell time than an SG approach.
