RESUMO
BACKGROUND: The focus of this research is to examine the growing use of robotic-assisted minimally invasive esophagectomy. Specifically, it evaluates the immediate clinical and cancer-related results of combining robotic-assisted minimally invasive esophagectomy with a systematic approach to total mesoesophageal excision, as opposed to traditional open transthoracic esophagectomy methods that do not employ a structured total mesoesophageal excision protocol. METHODS: A propensity score-matched analysis of 185 robotic-assisted minimally invasive esophagectomies and 223 open transthoracic esophagectomies after standardized Ivor Lewis esophagectomy was performed. After 1:1 nearest neighbor matching to account for confounding by covariates, outcomes of 181 robotic-assisted minimally invasive esophagectomy and 181 open transthoracic esophagectomy were compared. RESULTS: The patient characteristics showed significant differences in the age distribution and in comorbidities such as coronary heart disease, arterial hypertension, and anticoagulant intake. The R0-resection rate of robotic-assisted minimally invasive esophagectomy (96.7%) was significantly higher than open transthoracic esophagectomy (89.0%, P = .004). Thirty-day mortality and hospital mortality showed no significant differences. Postoperative pneumonia rate after robotic-assisted minimally invasive esophagectomy (12.7%) was significantly reduced (open transthoracic esophagectomy 28.7%, P < .001). Robotic-assisted minimally invasive esophagectomy had a significantly shorter intensive care unit stay (P < .001) and shorter hospital stay (P < .001). CONCLUSION: This single-center, retrospective study employing propensity score matching found that combining robotic-assisted minimally invasive esophagectomy with structured total mesoesophageal excision results in better short-term clinical and oncologic outcomes than open transthoracic esophagectomy. This finding is significant because the increased rate of R0 resection could indicate a higher likelihood of improved long-term survival. Additionally, enhanced overall postoperative recovery may contribute to better risk management in esophagectomy procedures.
