Indirect comparison of various lumen-apposing metal stents for EUS-guided biliary and gallbladder drainage: a systematic review and meta-analysis

Studies assessing endoscopic ultrasound guided biliary drainage (EUS-BD) or gallbladder drainage (EUS-GB) using lumen apposing metal stents (LAMS) have shown variable results based on the type of LAMS. We performed a meta-analysis of the available data.
