Background: Minimally invasive esophagectomy is the first-line approach for esophageal cancer; however, there has recently been a paradigm shift toward robotic esophagectomy (RE). We investigated the clinical outcomes of patients who underwent RE compared with those of patients who underwent conventional minimally invasive thoracoscopic esophagectomy (TE) for locally advanced cT3 or cT4 esophageal cancer using a propensity-matched analysis., Methods: Overall, 342 patients with locally advanced cT3 or cT4 esophageal cancer underwent transthoracic esophagectomy with total mediastinal lymph node dissection between 2018 and 2022. The propensity-matched analysis was performed to assign the patients to either RE or TE by covariates of histological type, tumor location, and clinical N factor., Results: Overall, 87 patients were recruited in each of the RE and TE groups according to the propensity-matched analysis. The total complication rate and the rates of the three major complications (recurrent laryngeal nerve paralysis, anastomotic leakage, and pneumonia) were not significantly different between the RE and TE groups. However, the peak C-reactive protein concentration on postoperative day 3, rate of surgical site infection, and intensive care unit length of stay after surgery were significantly shorter in the RE group than in the TE group. No significant differences were observed in the harvested total and mediastinal lymph nodes. The total operation time was significantly longer in the RE group, while the thoracic operation time was shorter in the RE group than in the TE group. There was no significant difference between the two groups in the recurrence rate of oncological outcomes after surgery., Conclusion: RE may facilitate early recovery after esophagectomy with total mediastinal lymph node dissection and has the same technical feasibility and oncological outcomes as TE., (© 2024.

Esophageal squamous cell carcinoma (ESCC) is one of the most common malignancies worldwide, especially in East Asia. ESCC accounts for more than 90% of esophageal cancer. Currently, neoadjuvant therapy in combination with surgical resection is the mainstay of treatment. However, the overall survival rate of patients with locally advanced ESCC is not satisfactory even when treated following the standard treatment guidelines. With neoadjuvant chemoradiotherapy, chemotherapy, or emerging immunotherapy, continuous exploration of efficacy in relation to ESCC is expected to improve overall survival further. Here, we review and summarize current evidence for efficacy of preoperative therapy for locally advanced ESCC., (© 2020 New York Academy of Sciences.)

Esophageal cancer surgery originated in the early 20(th) century. However, the true meaning of trans-thoracic esophagectomy and digestive tract reconstruction began in the 1930s. Almost at the same time, Japan and Western countries began the surgical exploration of esophageal cancer. Based on the pathological type of esophageal cancer in Asia, squamous cell carcinoma is the majority, and its biological characteristics and treatment strategies are different from those of European and American patients. After more than eighty years of development, the surgical treatment of esophageal cancer in Japan has been developed from the initial attempt, deep cultivation practice to the pursuit of excellence, and explored a set of more advanced surgical techniques and diagnostic strategies, which is unique in the world. On the basis of the establishment of the Japanese Society of Esophagus, Japanese scholars have developed and irregularly updated the Japanese Classification of Esophageal Cancer and published the professional academic journal Esophagus . The Japanese Clinical Oncology Group organized a number of phase Ⅲ clinical studies on esophageal cancer, providing strong evidence for the diagnosis and treatment of esophageal squamous carcinoma. Focused on the origin, development, current situation and future of esophageal cancer surgery in Japan, this paper summarized the development of esophageal cancer surgery in Japan through literature review, interviews with senior experts and Hot topics of esophageal cancer surgery-questionnaire survey of Japanese experts .
