The Impact of Hybrid Minimally Invasive Esophagectomy with Neck-Abdominal First Approach on the Short- and Long-Term Outcomes for Esophageal Squamous Cell Carcinoma.

BACKGROUND Currently, there is no consensus for an optimal minimally invasive esophagectomy (MIE) approach. This study aimed to compare hybrid MIE (hMIE) with neck-abdominal first approach to standard open esophagectomy (OE). METHODS Data from a cohort of 301 patients were retrospectively analyzed. All participants received either hMIE or OE for the treatment of esophageal squamous cell carcinoma at Tokyo Medical and Dental University between January 2003 and December 2013. Analyses included propensity score matching and the Kaplan-Meier statistical method to determine overall survival (OS) and disease-free survival (DFS) of the cohort. RESULTS After one-to-one propensity score matching, there were 68 patient pairs. The hMIE group had significantly lower incidence of severe postoperative complications (20.1% vs. 7.4%; p = 0.026) and severe respiratory complications (7.4% vs. 0%; p = 0.058) than the OE group. The 5-year oncological outcomes of the two groups were almost equivalent (OS: OE, 55.0%; hMIE, 69.0%; p = 0.063 and DFS: OE, 54.0%; hMIE, 62.0%; p = 0.28). CONCLUSIONS This study compared hMIE with neck-abdominal first approach to standard OE. The results showed significantly less severe postoperative complications for hMIE with neck-abdominal first approach in comparison with OE, without a compromise in long-term oncological outcomes.
