Propensity-Matched Analysis of the Short-Term Outcome of Robot-Assisted Minimally Invasive Esophagectomy Versus Conventional Thoracoscopic Esophagectomy in Thoracic Esophageal Cancer

Background In this matched-cohort study, we investigated the short-term outcome of robot-assisted minimally invasive esophagectomy (RAMIE) compared with conventional minimally invasive thoracoscopic esophagectomy (MIE) in esophageal cancer patients. Methods One hundred eighty-nine patients with thoracic esophageal cancer scheduled to undergo thoracic esophagectomy between 2020 and 2021 were assigned to either RAMIE or MIE. Then, we retrospectively evaluated the postoperative surgical complications between two groups in a propensity-matched analyzation. Results Based on the propensity-matched score, 50 patients who underwent RAMIE or MIE were selected. Thoracic surgery time in RAMIE/MIE group were 233.1/173.3 min ( p
