Outcomes of minimally invasive total mesoesophageal excision: a propensity score-matched analysis

Background This study aimed to investigate the safety and efficacy of minimally invasive total mesoesophageal excision (TME) for esophageal cancer. Methods We retrospectively collected data from patients with esophageal cancer who underwent esophagectomy at our center between January 2011 and June 2017. Among 611 eligible patients, 302 underwent minimally invasive total mesoesophageal excision (the TME group) and 309 underwent non-total mesoesophageal excision (the NME group). Outcomes were compared after 1-to-1 propensity score matching, and subgroup analyses were performed for cases involving pT1–2 or pT3–4a disease. Results The propensity score matching produced 249 pairs of patients. The TME group had a shorter operative time ( P
