[Comparison of clinical outcomes between Ivor-Lewis and Mckeown esophagectomy for middle or lower esophageal cancer].

<b>Objective:</b> To compare the short-term and long-term clinical effects of Ivor-Lewis and Mckeown esophagectomy in the treatment of middle or lower thoracic esophageal cancer. <b>Methods:</b> The clinical data of 716 patients with middle and lower thoracic esophageal cancer who underwent radical resection of Ivor Lewis or McKeown esophageal cancer in the Department of Thoracic Surgery, Cancer Hospital, Chinese Academy of Medical Science from March 2015 to October 2018 were analyzed retrospectively, and the perioperative indicators, postoperative complications and survival of the two surgical methods were compared. <b>Results:</b> Among 716 patients, 135 patients underwent Ivor Lewis esophagectomy and 581 patients underwent McKeown esophagectomy. Mckeown group was significantly superior to Ivor Lewis group in terms of total number of lymph node dissection [median number was 27 (19~37) vs 25(18~33)], total number of lymph node dissection stations [median number was 5(4~7) vs 5(4~5)], and number of lymph nodes dissection along recurrent laryngeal nerve [median number was 3 (1~6) vs 0 (0~3), <i>P</i>＜0.05]. However, the incidence of recurrent laryngeal nerve palsy in Mckeown group was significantly higher than that in Ivor Lewis group [10.7% (62/581) vs 1.5%(2/135), <i>P</i>＜0.001]. There was no significant difference in the 1 -, 3 -, 5-year overall survival between the Ivor Lewis group(91.0%, 70.5%, 52.9%) and the Mckeown group (89.7%, 68.4%, 62.4%, <i>P</i>＞0.05), and there was also no significant difference in the 1 -, 3 -, 5-year disease free survival between the Ivor Lewis group(77.0%, 54.1%, 44.0%) and the Mckeown group (78.3%, 59.0%, 52.8%, <i>P</i>＞0.05). <b>Conclusions:</b> Ivor Lewis esophagectomy and Mckeown esophagectomy are feasible, safe, good short-term efficacy and similar survival rate for middle and lower thoracic esophageal cancer. Ivor Lewis surgery has lower incidence of recurrent laryngeal nerve palsy. Mckeown operation has more advantages in lymph node dissection, especially in lymph node dissection beside the recurrent laryngeal nerve.
