Robotic Esophagectomy Compared With Open Esophagectomy Reduces Sarcopenia within the First Postoperative Year: A Propensity Score-Matched Analysis.

Sarcopenia is a known risk factor for adverse outcomes after esophageal cancer (EC) surgery. Robot-assisted minimally invasive esophagectomy (RAMIE) offers numerous advantages, including reduced morbidity and mortality. However, no evidence exists to date comparing the development of sarcopenia after RAMIE and open esophagectomy (OE). The objective was to evaluate whether the development of sarcopenia within the first postoperative year after esophagectomy is associated with the surgical approach: RAMIE versus OE. A total of 168 patients with EC were analyzed who either underwent total robotic or fully open Ivor Lewis esophagectomy in a propensity score-matched analysis. Sarcopenia was assessed using the skeletal muscle index (cm After 1-to-1 propensity score matching for confounders, 67 patients were allocated to RAMIE and OE groups, respectively. Skeletal muscle index in the OE group was significantly lower compared with the RAMIE group at the third (43.2 ± 7.6 cm To our knowledge, this study is the first to suggest a substantial benefit of RAMIE compared with open esophagectomy in terms of postoperative sarcopenia. These results add further evidence to support the implementation of the robotic approach in multimodal therapy of EC.
