1030 PROPHYLACTIC ENDOSCOPIC ULTRASOUND-GUIDED GALLBLADDER DRAINAGE IN PATIENTS WITH UNRESECTABLE MALIGNANT BILIARY OBSTRUCTION AND CYSTIC DUCT ORIFICE INVOLVEMENT: A …

Abstract:

Aim to determine if primary EUS-GBD in patients with MBO and OCD tumor involvement is superior than conservative management. Methods a single-center, randomized control trial. Primary EUS-GBD was performed using a 3.8 mm therapeutic echoendoscope and a lumen apposing metal stent (Hot Axios™ Stent and Electrocautery Enhanced Delivery System, Boston Scientific, MA) after conventional biliary drainage with SEMS. In the other arm, patients were submitted to conventional biliary drainage using SEMS without primary EUS-GBD. A sample size of 11 patients per group was estimated, considering the clinical success of EUS-GBD vs. percutaneous transhepatic gallbladder drainage (92% vs. 86%) and, a type I & II errors of 10% and 20%, respectively. Baseline characteristics were described and compared with their corresponding hypothesis testing. The primary outcome of the study was the occurrence of …
