Abstract
BACKGROUND: Utilization of robotic-assistance for esophagectomy is increasing. The differences in outcomes between robotic-assisted minimally-invasive esophagectomy (RAMIE) and non-robotic minimally-invasive esophagectomy (MIE) for esophageal cancer are unknown. The purpose of this study was to compare 30-day postoperative outcomes between RAMIE and MIE. METHODS: A retrospective analysis was conducted using the ACS-NSQIP 2016-2017 databases. Primary outcome was 30-day postoperative mortality and morbidity. RESULTS: 725 minimally-invasive cases were identified, which included 100 RAMIE and 625 MIE. RAMIE was not found to be a risk factor for postoperative mortality (OR 1.50, 95% CI 0.38-6.00, p = 0.5675) or overall morbidity (OR 0.65, 95% CI 0.40-1.06, p = 0.0818). No significant differences were found between groups for systemic, organ-specific, or surgical complications. CONCLUSIONS: No significant difference was found in the incidence of 30-day postoperative outcomes between RAMIE and MIE. In comparison to MIE, RAMIE may be considered a feasible but non-superior option for treatment of esophageal cancer.
