Postoperative outcomes in robotic gastric resection compared with laparoscopic gastric resection in gastric cancer: A meta-analysis and systemic review.

BACKGROUND

Robotic gastrectomy is a commonly used procedure for early gastric cancer and it also overcomes the limitation of laparoscopic. However, the complications of robotic gastrectomy (RG) still need to be assessed. Our study was designed to compare postoperative complications of RG with laparoscopic gastrectomy (LG).

MATERIALS AND METHODS

A meta-analysis and systemic review were prospectively collected using the PubMed, Cochrane Library, and MEDLINE database of published studies by comparing the RG and LG with gastric cancer up to December 2021. To evaluate the postoperative outcomes, odds ratios were calculated for Dichotomous data and the mean difference with 95% confidence interval (CI) was calculated for continuous data, and measured by the random-effect model.

RESULTS

Thirty-two retrospective studies describing 13,585 patients (4484 RG and 9101 LG) satisfied the inclusion criteria. A statistically significant result was in blood loss (MD = -17.97, 95% Cl: -25.61 to 10.32,  < 0.001), Clavien-Dindo grade Ⅲ (odds ratio (OR) = 0.60, 95% CI: 0.48-0.76,  < 0.01), and harvested lymph node (MD = 2.62, 95% CI: 2.14-3.11,  < 0.001). There was no significant difference between robotic gastrectomy surgery (RGS) and laparoscopic gastrectomy surgery (LGS) regarding distal resection margin (DRM), proximal resection margin (PRM), conversion rate, anastomotic leakage, and overall complications.

CONCLUSION

Having significant outcomes in Clavien-Dindo grade III, and blood loss, harvested lymph nodes are more common in RGS, and they also help in increasing the quality of life.
