Background
Whether robot-assisted minimally invasive surgery (RAMIE) is more beneficial than conventional minimally invasive surgery (MIE) remains unclear.
Methods
In total, 165 consecutive patients with esophageal carcinoma who underwent esophagectomy between January 2015 and April 2020 were retrospectively assessed. A 1:1 propensity score matching analysis was performed to compare the short-term outcomes between RAMIE and conventional MIE.
Results
After matching, 45 patients were included in the RAMIE and conventional MIE groups. RAMIE had a significantly longer total operative time (708 vs. 612 min, P < 0.001) and thoracic operative time (348 vs. 285 min, P < 0.001) than conventional MIE. However, there were no significant differences in terms of oncological outcomes, such as R0 resection rate and number of resected lymph nodes. The overall postoperative morbidity (Clavien–Dindo [C–D] grade II or higher) rate of RAMIE and conventional MIE were 51% and 73% (P = 0.03), respectively, and the severe postoperative morbidity (C–D grade III or higher) rates were 11% and 29% (P = 0.04), respectively. The incidence rate of recurrent laryngeal nerve palsy was halved in RAMIE (7%) compared with conventional MIE (20%) (P = 0.06). Finally, the pulmonary complication rate (18%) was significantly lower in patients who underwent RAMIE than in those who underwent conventional MIE (44%) (P = 0.006).
Conclusions
RAMIE was safe and feasible, even during the early period of its application at a specialized center. Moreover, it may be a promising alternative to conventional MIE, with better short-term outcomes, including significantly lower incidence of pulmonary complications.
