Abstract
IntroductionRobot-assisted oesophagectomy (RAE) and thoracolaparoscopic oesophagectomy (TLE) are surgical techniques for the treatment of oesophageal cancer. This study aimed to compare the perioperative and mid-term outcomes of RAE versus TLE for patients with locally advanced oesophageal squamous cell carcinoma (ESCC) undergoing neoadjuvant chemoradiotherapy (nCRT). MethodsConsecutive patients receiving nCRT plus RAE or TLE were retrospectively included in this single-institution study from January 2016 to January 2021. Perioperative outcomes were compared and survival analysis was performed. ResultsThis study enrolled 251 patients, 80 (31.9%) in RAE and 171 (68.1%) in TLE. The conversion rate was equivalent in RAE versus TLE (3.8% vs 2.9%, P = 1). Median operative time in RAE was significantly shorter than that in TLE (254 vs 289 min, P < 0.001). Compared to TLE, RAE harvested more lymph nodes along the recurrent laryngeal nerve [4 (3–6) vs 3 (1–5), P < 0.001]. Overall complications were similar in RAE compared to TLE (38.8% vs 38.0%, P = 0.911). No statistically significant difference in disease-free survival (log-rank P = 0.721) or overall survival (log-rank P = 0.325) was found between groups. ConclusionsCompared to TLE, RAE could achieve shorter operative duration and better lymph nodes dissection along the bilateral RLN for locally advanced ESCC after nCRT, with comparable short-term outcomes. A long-term survival remains to be verified.
