Abstract
BACKGROUND AND AIMS: Efficacy and safety of EUS-guided placement of lumen-apposing metal stents (LAMS) has been reported yet advantage of using 15-mm LAMS over 10-mm LAMS yet to be explored.
METHODS: International, retrospective, case-matched study of patients with intra-abdominal abscess who underwent EUS-guided drainage with 15-mm (case) and 10-mm (control) LAMS between 03/2019 and 09/2022.
RESULTS: 51 patients underwent EUS-guided drainage using LAMS [15-mm 29 (57%), 10-mm 22 (43%)]. The most common location of the abscess was peri-pancreatic 43%. Technical success rate was achieved in 97% of cases and 100 % of controls (p=0.412), while clinical success was achieved in 98% and 96%, respectively, (OR 1.3; p=0.089). AE occurred in 7.8% of the cases. Patients with 15-mm LAMS underwent fewer total endoscopic procedures (mean 2.5 vs.3.6; P < 0.023).
CONCLUSION: Both sizes showed comparable clinical success and safety profiles, with a significant trend of the need for fewer endoscopic procedures with the 15-mm LAMS.
