ObjectiveTo explore the clinical effect of 3D laparoscopy combined with rigid choledochoscopy applied to minimally invasive gallbladder-preserved cholecystolithotomy in cholecystolithiasis treatment. MethodsSixty-six patients with cholecystolithiasis were enrolled and randomly divided into observation group and control group, with 33 cases in each group. Patients in the observation group were treated with minimally invasive gallbladder-preserved cholecystolithotomy using 3D laparoscopy combined with rigid choledochoscopy, while patients in the control group received minimally invasive gallbladder-preserved cholecystolithotomy using 2D laparoscopy combined with rigid choledochoscopy. The therapeutic effects were compared between the two groups. ResultsAll patients completed the operation successfully, and no conversion to open surgery or change of operation approach for cholecystectomy occurred. The calculi removal rate was 100% in both groups. The operation duration and gallbladder incision suture time in the observation group were less than those in the control group (all P＜0.05). There were no statistically significant differences in intraoperative blood loss, calculi removal rate, postoperative hospital stay, or the incidence rate of complication between the two groups (all P＞0.05). After 12 months of follow-up, one case suffering from recurrent cholecystolithiasis was observed in each group (3.03%). ConclusionCompared with 2D laparoscopy, 3D laparoscopy combined with rigid choledochoscopy can shorten the suture time and operation duration of gallbladder incision in minimally invasive gallbladder-preserved choledostolithotomy, which is safe, feasible and efficient, with a preferable clinical application prospect.
