Resolución de coledocolitiasis compleja con stent metálico removible. Reporte de un caso

Abstract

Extraction can turn out to be complex in 15-20% of choledochal stones due to size (> 15 mm), number (≥ 3), or the container-content dissociations determining impactions. Under these adverse circumstances, other endoscopic techniques should be applied: large-volume balloon dilation or mechanical, laser, or electrohydraulic lithotripsy. If therapeutic success is not achieved, the placement of plastic biliary stents is employed as a bridge until definitive intervention. Over the last decade, the useof self-expanding metal stents in the context of benign biliary pathology has increased, but their role in treating biliary stones has not been described.6---8We present herein the case of complex bile duct stones resolved through the placement of a removable metallic biliary stent.
