Abstract
Abstract Background Mediastinoscope-assisted transhiatal esophagectomy (MATHE) is the most minimally invasive esophagectomy procedure. It is a more challenging procedure and more difficult to be popularized than thoracoscopic surgery. We developed a new MATHE operation mode that provides a clearer visual field and makes the procedures simpler. Methods A total of 48 patients with esophageal cancer were divided into a control group (n = 29) and a study group (n = 19). The control group underwent classic MATHE, while the study group received modified MATHE. We compared the two groups on operation time; intraoperative blood loss; blood transfusion amount; incidence rate of lung infection, recurrent laryngeal nerves (RLNs) injury, chylothorax, and anastomotic leakage; and upper mediastinal lymph node dissection. Results The study group was significantly better than the control group in operation time (273.94 min vs. 322.90 min, p < 0.05), intraoperative blood loss (46.84 mL vs. 68.97 mL, p < 0.05), and left paratracheal lymph node (No. 4 L) dissection rate (84.21% vs. 24.14%, p < 0.01). No significant differences were identified in the incidence rate of anastomotic leakage, lung complications, or RLNs injury between the two groups. Conclusion The modified MATHE is easier to perform. Modified MATHE is significantly superior to classic MATHE in operation time, intraoperative blood loss, and upper mediastinal lymph node dissection rate.
