Short-term outcomes of Da Vinci robotic surgical system and laparoscopy in pancreaticoduodenectomy: a Meta analysis

Abstract

Objective To systematically evaluate the short-term outcomes of Da Vinci robotic surgical system and laparoscopy in pancreaticoduodenectomy. Methods Literatures were researched using PubMed, Embase, Medline, VIP database, Chinese Journal Fulltext Database from January, 2013 to October, 2016 with the key words includinglaparoscopic, robotic, Da Vinci, pancreaticoduodenectomy,腹腔镜,达芬奇机器人,胰十二指肠切除术. The cohort studies about comparison of short-term outcomes of Da Vinci robotic surgical system and laparoscopy in pancreaticoduodenectomy were received and enrolled. Patients undergoing pancreaticoduodenectomy using Da Vinci robotic surgical system and laparoscopy were respectively allocated into the Da Vinci group and laparoscopy group. Two reviewers independently screened literatures, extracted data and assessed the risk of bias. Count data were described as odd ratio (OR) and 95% confidence interval (CI). Measurement data were represented as weighted mean difference (WMD) and 95%CI. The heterogeneity of the studies was analyzed using the I2 test. Results Five retrospective cohort studies were enrolled in the Meta analysis, and the total sample size was 364 patients, including 159 in the Da Vinci group and 205 in the laparoscopy group. The results of Meta analysis showed that there were statistically significant differences in the rate of conversion to open surgery, spleen-preserving rate, operation time and duration of postoperative hospital stay between Da Vinci group and laparoscopy group (OR=0.18, 3.80, WMD=-37.54, -4.47, 95%CI: 0.05-0.60, 2.01-7.18, -47.46--27.62, -6.70--2.24, P 0.05). Conclusions Da Vinci robotic surgical system and laparoscopy are safe and feasible in pancreaticoduodenectomy, with the same incidence of postoperative complications. Compared with laparoscopy, Da Vinci robotic surgical system can not only reduce the rate of conversion to open surgery, operation time and duration of postoperative hospital stay, but also increase spleen-preserving rate, meanwhile, it does not increase the incidence of postoperative complications.
