Minimally invasive esophagectomy for esophageal cancer according to the location of the tumor: Experience of 251 patients

Abstract Background Minimally invasive esophagectomy (MIE) is increasingly used for the treatment of esophageal cancer. However, the ideal approach of MIE is not yet standardized. We explore the ideal approach of MIE according to the location of the tumor and compare the clinical outcomes between patients with cancer arising in the upper third of the esophagus and those with tumors involving the middle and lower third of the esophagus. Methods We included patients with esophageal carcinoma and had clear indications for MIE. For cancer arising in the upper third of the esophagus, MIE McKeown approach was performed. For tumors involving the middle and lower third of the esophagus, MIE Ivor Lewis approach was adopted. Results Of the 251 patients included in this analysis, 200 patients underwent Ivor-Lewis MIE and 51 patients underwent McKeown MIE. The incidence of anastomotic leak, anastomotic stenosis and recurrent laryngeal nerve injury was significantly higher in the McKeown MIE group than that in the Ivor Lewis MIE group. The 30-day postoperative mortality rate was 1.2% (n = 1) in the McKeown MIE group. Lymph nodes harvested were significantly more in the MIE-McKeown group than in Ivor Lewis MIE group (P
