Abstract
BACKGROUND AND OBJECTIVE: Transcervical inflatable mediastinoscopic esophagectomy (TIME) is a novel method of minimally invasive esophagectomy (MIE) for esophageal cancer. However, whether TIME is effective and feasible as conventional MIE remains unclear. This study aimed to evaluate the efficacy of TIME by comparing it with thoracoscopic esophagectomy (TE). METHODS: Surgical outcomes and relapse-free survival (RFS) rates of patients with local early- or intermediate-stage thoracic esophageal squamous cell carcinoma that underwent TIME or TE from January 2017 to December 2019 were analyzed in this retrospective study. Propensity score matching was used to control the confounding factors. RESULTS: The mean operation time in TIME was shorter than that in TE (p < 0.05). Patients in the TIME group achieved postoperative ambulation earlier than those in the TE group (p < 0.05). The rate of pulmonary complications was lower in TIME than in TE (p < 0.05). The number of lymph nodes harvested during surgery and the RFS rates of two groups did not have significant differences. CONCLUSION: TIME may be a feasible and safe method to treat local early- and intermediate-stage thoracic esophageal squamous cell carcinoma effectively and it could be a supplementary surgical method of TE for patients with poor pulmonary function or cannot undergo TE.
