Background Though robot-assisted minimally invasive esophagectomy (RAMIE) is demonstrated to offer a better visualization and provide a fine dissection of the mediastinal structures to facilitate the complex thoracoscopic operation, the superiorities of RAMIE over MIE have not been well verified. The aim of this study was to explore the actual superiorities through comparing short-term results of RAMIE with that of MIE. Methods PubMed, EMBASE and web of science databases were systematically searched up to September 1, 2020 for case-controlled studies that compared RAMIE with TLMIE. Results Fourteen studies were identified, with a total of 2,887 patients diagnosed with esophageal cancer, including 1,435 patients subjected to RAMIE group and 1,452 patients subjected to MIE group. The operative time in RAMIE was still significantly longer than that in MIE group (OR =0.785; 95% CI, 0.618-0.952; P<0.001). The incidence of pneumonia was significantly lower in RAMIE group compared with MIE group (OR =0.677; 95% CI, 0.468-0.979; P=0.038). Conclusions RAMIE has the superiorities over MIE in short-term outcomes in terms of pneumonia and vocal cord palsy. Therefore, RAMIE could be considered as a standard treatment for patients with esophageal cancer.
