Abstract

We aimed to compare the short- and long-term outcomes between robotic esophagectomy (RE) and open esophagectomy (OE) in patients with esophageal squamous cell carcinoma (ESCC). Among the patients who underwent esophagectomy for ESCC from 2008 to 2017, 402 patients (n = 178 in RE and n = 224 in OE) were enrolled and, after propensity-score matching, 136 patients in each group were selected. The total rate of complications was comparable, whereas the rate of major complications was higher in OE (p < 0.01). Hospital stay was longer in OE (15 days in OE vs. 13 days in RE; p = 0.03) with a comparable early mortality rate. Complete resection was equally achieved in both groups (96.3% in RE vs. 97.0% in OE; p = 0.74). The numbers of retrieved lymph nodes (LN) were significantly higher in RE (42.8 in RE vs 35.3 in OE; p < 0.01), especially for LNs in the left lower cervical paratracheal, both recurrent laryngeal nerves, and paraesophageal area. The 5-year overall survival rate was higher in RE (75.1% in RE vs. 57.9% in OE; p = 0.02), whereas, the freedom from recurrence was comparable between the two groups (68.8% in RE vs. 54.7% in OE; p = 0.15). Notably, RE achieved a significantly higher rate of 5-year freedom from regional nodal recurrence than OE (81.4% in RE vs. 62.7% in OE, p = 0.03). RE contributed to a lower rate of major complications and shorter hospital stays. Furthermore, RE showed increased long-term overall survival and freedom from regional LN recurrence rates, with a higher yield of LN dissection compared to OE.
