To systematically evaluate the prognostic efficacy of robotic-assisted total gastrectomy.
Through PubMed, Embase, Cochrane Library, Ovid and other databases, English-language literature comparing the three different surgical approaches of conventional open total gastrectomy, laparoscopic-assisted total gastrectomy and robotic-assisted total gastrectomy published from 2015 to December 2021 was collected. NoteExpress was used to complete the literature screening process and to evaluate the quality of the included literature using the JADAD scale and NOS scale. R-Studio software and Review Manager 5.4 software were used to perform the net Meta-analysis.
A total of 39,918 patients from 33 papers were eventually included in the study.Meta-analysis showed that robotic total gastrectomy took the longest operative time and was the most prone to postoperative abdominal haemorrhage of the three procedures included, but was the most effective in reducing postoperative hospital stay, preventing postoperative abdominal infection, postoperative pneumonia, postoperative anastomotic leakage and overall postoperative complications.
The da Vinci robot is safe and feasible in the treatment of gastric cancer. There are advantages and disadvantages to robotic-assisted treatment, and we look forward to continued improvements in the technology in the future, thereby improving the quality of life for patients with gastric cancer.
