Objectives

Narrative objectives1

The aim of this study was to evaluate the efficacy of endoscopic treatment of asymptomatic common bile duct stones and the natural history of asymptomatic stones in a multicenter setting. The results of this study may contribute to a change in treatment strategy for asymptomatic common bile duct stones. It will also provide some insight into the natural history of common bile duct stones, which is still unknown.
