A Multicenter Randomized Controlled Study of 3D Laparoscopy Versus Endoscopy in the Treatment of Choledocholithiasis

The incidence of choledocholithiasis is gradually rising with the increase of gallstone incidence. The popular minimally invasive treatment options include endoscopic retrograde cholangiopancreatography (ERCP) and laparoscopic common bile duct exploration (LCBDE). Currently, three-dimensional (3D) video system for laparoscopy is developed to ofer surgeon a superior depth perception and a much better user experience, thus potential increasing operation accuracy and stability. It have suggested that compared with 2D laparoscopy, 3D laparoscopy can effectively reduce operation time and numbers of errors. However, rare experimental studies are performed to evaluate the safety and effectiveness of 3D laparoscopy in choledocholithiasis patients. The aim of this study is to compare the perioperative outcomes between 3D laparoscopy and ERCP in choledocholithiasis patients through a multicenter randomized controlled design.
