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 < 0.01), respectively. No significant intergroup differences were observed regarding incisional anastomotic leakage (RAMIE group 4.0% vs. MIE group 6.0%) and pneumonia (RAMIE group 8.0% vs. MIE group 12.0%; p = 0.68). The respective incidences of recurrent laryngeal nerve paralysis were 34.0 and 8.0% in the MIE and RAMIE groups, respectively (p < 0.01). In the matched cohort, no differences were observed between the groups in the success accomplishment of the clinical management pathway (RAMIE group 94.0% vs. MIE group 88.0%).
Conclusions
Although patients who underwent RAMIE had longer operation times, the incidence of recurrent laryngeal nerve paralysis was lower than with MIE. Further study in a prospective multi-institutional setting are required to confirm the superiority of RAMIE compared with MIE.
