Abstract

Lumen-apposing metal stents (LAMSs) were primarily designed for endoscopic ultrasound (EUS) guided drainage of peripancreatic fluid collections and have since gained wide clinical acceptance for this indication. Off-label use of LAMS grew rapidly afterwards, and multiple reports demonstrated the efficacy and safety of EUS-guided gastrointestinal anastomosis (EUS-GIA) through transmural LAMS placement. Endoscopists have since used EUS to obtain biliary and pancreatic access in postsurgical anatomy, to bypass gastric outlet obstruction, and to decompress the afferent loop. EUS-GIA has since gained significant traction with increased uptake among endoscopists and may potentially become standard of care for many of these indications. However, procedural standardization remains an issue. In this narrative review we will cover the current indications, technique, outcomes, and evidence related to EUS-GIA.

Core Tip: Endoscopic ultrasound (EUS)-guided gastrointestinal anastomosis has emerged as a highly effective minimally invasive platform for managing complex obstructive and altered anatomy conditions, including malignant gastric outlet obstruction, endoscopic retrograde cholangiopancreatography (ERCP) in Roux-en-Y gastric bypass, and afferent loop syndrome. Recent randomized data support EUS-guided gastroenterostomy as an effective alternative to surgical bypass and duodenal stenting. EUS-directed transgastric ERCP demonstrates comparable technical success to laparoscopy-assisted ERCP with shorter procedural times. As device technology and standardization improve, EUS-guided gastrointestinal anastomosis is poised to become an integral component of advanced therapeutic endoscopy.
