Reconstruction using robotic assistance in pancreaticoduodenectomy (PD) was expected to be an effective means to overcome the limitations of laparoscopic surgery. To our knowledge, few comparative reports exist on the outcomes of totally laparoscopic PD (TLPD) and robot-assisted laparoscopic PD (RLPD). This retrospective study aimed to analyze the surgical results of TLPD and RLPD in a high-volume pancreatic center.
We analyzed the surgical results of consecutive patients who underwent a minimally invasive PD for malignant or benign periampullary lesions between January 2016 and May 2020. Forty-three TLPD patients and 49 RLPD patients were enrolled.
There were no significant differences in the demographic characteristics between the 2 groups except for tumor size, which was significantly larger in the RLPD group than in the TLPD group (mean, 3.1 cm vs. 2.5 cm; P = 0.035). The RLPD group had shorter whole operative times (mean, 400.4 minutes vs. 352.2 minutes; P = 0.003) and shorter anastomosis times than the TLPD group (mean, 94.5 minutes vs. 54.9 minutes; P < 0.001). There was no significant difference between the 2 groups in the rate of pancreatic fistulas, morbidity, and mortality. However, a significantly lower wound infection rate was found in the RLPD group relative to the TLPD group (0% vs. 9.3%, P = 0.038).
RLPD showed the advantage of reducing the operation time compared to TLPD as well as technical feasibility and safety.
