To investigate the advantage of three-dimensional (3D) laparoscopy in the treatment of cholecystolithotomy combined with choledochoscopy.

From Apr. to Oct. 2015, 33 patients underwent cholecystolithotomy by 2D laparoscopy combined with choledochoscopy (2D group) and 30 patients received 3D laparoscopic cholecystolithotomy (3D group) in the hepatobiliary surgery department of Shanghai East Hospital. The surgical data including the operative time, the time of gallbladder′s suture and the intraoperative blood loss were compared between the two groups.

30 patients in 2D group and 26 patients in 3D group were successfully received the cholecystolithotomy by laparoscopy combined with choledochoscopy. 3 patients in 2D group and 4 patients in 3D group were converted to laparoscopic cholecystectomy (P>0.05). The time of gallbladder′s suture was significantly shorter in 3D group [(29.4 ± 4.7)min, (11.7 ± 2.4)min, (8.5 ± 3.2)ml] than in 2D group[(31.7 ± 4.8)min, (14.2 ± 3.0)min, (9.1 ± 3.8)ml], [(11.7 ± 2.4) min vs (14.2 ± 3.0) min, P<0.05)]. No significant differences were found in the operative time and the intraoperative blood loss between the two groups (P>0.05). All patients were all followed up for 6 months postoperatively without stones recurrent and readmission.

3D laparoscopic cholecystolithotomy combined with choledochoscopy is safe and effective. To a certain extent, it can shorten the time and improve the quality of the gallbladder suture, reduce the operation difficulty. Thus it will be a better choice for the treatment of cholecystolithotomy by laparoscopy combined with choledochoscopy.
