BACKGROUND: Endoscopic removal of packed, large, or impacted stones, in which a basket cannot be deployed or is unable to grasp the stone(s), is challenging and inevitably leads to repeated procedures such as stent insertion and extra- or intracorporal lithotripsy. In this study, we describe the results of an alternative stone disintegration technique in a considerable series of patients using an esophageal/pyloric balloon for stone fragmentation or making working space in the bile duct to allow the deployment of the basket, a technique we call endoscopic biliary large balloon lithotripsy.
METHODS: We retrieved data from 1,429 endoscopic retrograde cholangiopancreatographies (ERCPs) from 2 prospective trials performed between 2014 and 2019. Patients with difficult bile duct stones, in which a balloon dilator up to 15 mm was used to crush or increase the working space parallel to the stones in the common or hepatic duct, were included in the study.
RESULTS: From the 1,429 ERCPs, 299 had difficult stones (>1 cm, impacted or multiple stones). Large balloon lithotripsy was employed in 46 cases after endoscopic papillotomy and endoscopic biliary large balloon dilation with failed attempted balloon or basket stone(s) extraction. Failure to clear the bile duct at first ERCP occurred in 4 cases (91.3% of success). Complications were observed in 5 patients (10.8%; 1 perforation, 1 pancreatitis, and 3 bleedings), who were treated conservatively.
CONCLUSIONS: Large balloon lithotripsy, in order to crush the stones or make working room for baskets or balloons in the bile duct, is an effective, safe, and low cost technique for impacted, packed, or giant bile duct stones.
