Background
Most studies on endoscopic ultrasound (EUS)-guided gastroenterostomy (EUS-GE) for palliation of malignant gastric outlet obstruction (GOO) utilized a 15-mm lumen-apposing metal stent (LAMS). More recently, a 20-mm LAMS has become available. This study aimed to compare rates of technical and clinical success and adverse events (AEs) in patients undergoing EUS-GE using a 20-mm vs. 15-mm LAMS.
Methods
Patients who underwent EUS-GE with 15-mm or 20-mm LAMS for malignant GOO during the period from January 2018 to October 2020 were included. The primary outcome was clinical success, defined as an increase in the gastric outlet obstruction score (GOOS) by at least 1 point during follow-up. Secondary outcomes were technical success, maximum tolerated diet, re-intervention rate, and rate/severity of AEs.
Results
267 patients (mean age 67 years, 43 % women) with malignant GOO from 19 centers underwent EUS-GE. Clinical success rates were similar for the 15-mm and 20-mm stents (89.2 % [95 %CI 84.2 %–94.2 %] vs. 84.1 % [77.4%–90.6 %], respectively). However, a significantly higher proportion of patients in the 20-mm group tolerated a soft solid/complete diet at the end of follow-up (91.2 % [84.4 %–95.7 %] vs. 81.2 % [73.9 %–87.2 %], P = 0.04). Overall, AEs occurred in 33 patients (12.4 % [8.4 %–16.3 %]), with similar rates for 15-mm and 20-mm stents (12.8 % [7.5 %–18.2 %] vs. 11.8 % [6 %–17.6 %]), including incidence of severe/fatal AEs (2 % [0.4 %–5.8 %] vs. 3.4 % [0.9 %–8.4 %]).
Conclusions
The 20-mm and 15-mm LAMS show similar safety and efficacy for patients undergoing EUS-GE for malignant GOO. The 20-mm LAMS allows a more advanced diet and is, thus preferred for EUS-GE.
