Outcomes of EUS-guided transluminal gallbladder drainage in patients without cholecystitis

Background and Objectives: Cholecystectomy is the gold standard for most gallbladder-related disease. However, many patients with gallbladder disease are poor surgical candidates. Current nonsurgical gallbladder drainage (GBD) methods include percutaneous cholecystostomy and endoscopic ultrasound-guided transluminal GBD (EUS-GBD). Outcomes for EUS-GBD for the treatment of noncholecystitis (NC) gallbladder disease have not been defined. Materials and Methods: Cases were identified using procedural data from a quaternary academic hospital for endoscopic procedures from 2015 to 2020. Patients who underwent EUS-GBD for acute cholecystitis, biliary colic, gallstone pancreatitis, and secondary prevention of gallstone disease were included. Results: Fifty-five cases of EUS-GBD were identified over the 5-year study period. Forty-one cases were performed for acute cholecystitis, and 15 were performed for other NC indications. Indications for NC drainage included primary treatment of symptomatic biliary colic and secondary prevention of gallstone pancreatitis and choledocholithiasis. There was no statistically significant difference in complications, mortality, or reintervention requirements. There was a 13.3% rate of immediate complications in the NC group, which were all medically managed. Conclusions: EUS-GBD appears to be a safe and effective way to manage gallstone disease in nonsurgical candidates with NC gallbladder-related disease. Overall complications and readmissions were infrequent. Complication rates were similar to those published in patients who underwent EUS-GBD for acute cholecystitis.
