Abstract
BACKGROUND: This study was designed to investigate whether 3D laparoscopic common bile duct (LCBDE) could improve surgical outcomes in choledocholithiasis patients compared with 2D LCBDE. METHOD: Propensity score-matched analysis was performed to balance the bias in baseline characteristic between two groups. RESULTS: 213 patients underwent 3D LCBDE and 212 patients receiving 2D LCBDE were enrolled in this study. The operation time and blood loss in 3D group were significantly less than that in 2D group. After propensity score matching, a total of 114 paired cases were selected from the two groups. The operation time and blood loss in 3D group remain significantly lower than in 2D group. In the end, the subgroup analysis based on abdominal adhesion level was performed and it was observed that for patients with adhesion level 1 and level 2, 3D surgery could obviously decrease the operation time and intraoperative blood loss. CONCLUSIONS: 3D LCBDE would significantly reduce operation time, blood loss, and conversion rate to laparotomy in choledocholithiasis patients versus 2D LCBDE. For patients with abdominal adhesions level 1 and level 2, 3D LCBDE could provide better surgical outcomes than 2D LCBDE.
