SUMMARY Robots are increasingly used in minimally invasive surgery. We evaluated the clinical benefits of robot-assisted minimally invasive esophagectomy (RAMIE) in comparison with the conventional open esophageal surgery. From 2012 to 2016, 371 patients with esophageal squamous cell carcinoma underwent an Ivor Lewis or McKeown procedure at our institution. Of these, 130 patients underwent laparoscopic gastric conduit formation followed by RAMIE, whereas 241 patients underwent conventional esophageal surgery, including laparotomy and open esophagectomy (OE). We compared the short- and long-term clinical outcomes of these patients using the propensity score-based inverse probability of treatment weighting technique (IPTW). Among the early outcomes, the OE group showed a higher incidence of pneumonia (P = 0.035) and a higher requirement for vasopressors (P = 0.001). Regarding the long-term outcomes, all-cause mortality was significantly higher (P = 0.001) and disease-free survival was lower (P = 0.006) in the OE group. Wound-related problems also occurred more frequently in the OE group (P = 0.020) during the long-term follow-up. There was no statistical intergroup difference in the recurrence rates (P = 0.191). The Cox proportional-hazard analysis demonstrated that wound problems (HR 0.16, 95% CI 0.02–0.57; P = 0.017), pneumonia (HR 0.23, 95% CI 0.06–0.68; P = 0.019), and use of vasopressors (HR 0.14, 95% CI 0.08–0.25; P = 0.001) were independent predictors of mortality. RAMIE could be a better surgical option for selected patients with esophageal squamous cell carcinoma.

The aim of this study was to compare the perioperative outcomes and long-term survival rates of the McKeown and Sweet procedures in patients with esophageal cancer younger than 70 years or older than 70 years. A total of 1432 consecutive patients with esophageal squamous cell carcinoma (ESCC) who received surgery at Sun Yat-sen University Cancer Center from January 2009 to October 2012 were analyzed. Propensity score matching was used to balance the clinical characteristics of the patients who underwent different surgical approaches, and 275 and 71 paired cases were matched among those younger and older than 70 years, respectively. The prognosis and postoperative outcomes were compared between the McKeown and the Sweet esophagectomy. For patients younger than 70 years, those who underwent the McKeown procedure had better overall survival (OS) than those in the Sweet group (log rank = 4.467; P = .035). However, no significant difference in disease-free survival and OS was observed between two approaches for the elderly patients (log rank = 1.562; P = .211 and log rank = 0.668; P = .414, respectively). Cox regression analysis revealed that McKeown approach was a positive prognostic factor compared to the Sweet approach for patients younger than 70 years in univariable analysis (HR = 0.790; 95% CI, 0.625-0.997; P = .047), whereas the surgical approach was not significantly related to the prognosis in the elderly patients. For patients older than 70 years, the occurrence of anastomotic fistula increased in those who underwent the McKeown procedure (23.9% vs 11.3%, P = .038, for the McKeown and Sweet esophagectomy, respectively). The McKeown approach increases the OS in younger patients with ESCC. However, for patients older than 70 years, the Sweet approach was proven to be an effective therapy, given the better perioperative outcomes and similar long-term survival compared with patients in the McKeown group.

SUMMARY This study aims to investigate advantages of robot-assisted minimally invasive esophagectomy (RAMIE) over video-assisted minimally invasive esophagectomy (VAMIE) in treating esophageal squamous cell carcinoma by applying propensity score-matched analysis. From April 2016 to January 2018, consecutive patients undergoing a McKeown RAMIE or VAMIE for esophageal squamous cell carcinoma were prospectively included for analysis. Baseline data, pathological findings, and short-term outcomes of the two groups (RAMIE group and VAMIE group) were collected and compared. Propensity score-matched analysis was applied to generate matched pairs for further comparison. Finally, we included a total of 151 patients (RAMIE group: 79 patients, VAMIE group: 72 patients) for analysis. In the analysis of unmatched cohort, RAMIE yielded a significantly larger number of total dissected lymph nodes (mean: 20.6 ± 8.8 vs. 17.9 ± 7.7; P = 0.048) and abdominal lymph nodes (mean: 9.5 ± 6.8 vs. 7.4 ± 5.1; P = 0.039) than VAMIE. However, there was no significantly different risk of major complications between the two groups. In the analysis of matched cohort, RAMIE still yielded a significantly larger number of total dissected lymph nodes (P = 0.006) and abdominal lymph nodes (P = 0.042) than VAMIE. There was still no increased risk of postoperative major complications in the RAMIE group compared to the VAMIE group. Moreover, RAMIE was found to yield significantly more left recurrent laryngeal nerve lymph nodes (mean: 1.0 ± 1.8 vs. 0.4 ± 0.8; P = 0.033) than VAMIE without increasing the risk of recurrent laryngeal nerve paralysis. Therefore, RAMIE may have the advantage of lymphadenectomy over VAMIE without increasing any risk of postoperative major complications. Further well-conducted studies, however, are needed to confirm our conclusions.
