Minimally invasive Ivor-Lewis Esophagectomy (MIE) is widely accepted as a surgical treatment of resectable esophageal cancer. Aim of this paper is to describe the surgical details of our standardized MIE technique and its safety. We also evaluate the esophageal mobilization in semiprone compared to the left lateral position. A retrospective analysis of 141 consecutive patients who underwent Ivor-Lewis esophagectomy for cancer, from February 2016 to September 2021, was conducted. All the procedures were performed by totally thoraco-laparoscopic with an intrathoracic end-to-side circular stapled anastomosis. Thoracic phase was performed in left lateral position (LLP-group, n=47) followed by a semiprone position (SP-group, n=94). The intraoperative and postoperative outcomes were prospectively collected and analyzed. The procedure was completed without intraoperative complication in 94.68% of cases in SP-group and in 93.62% of cases in LLP-group (P=0.99). The total operative time and thoracic operative time were significantly shorter in SP-group (P=0.0096; P=0.009). No statistically significant differences were detected in postoperative outcomes between the groups, except for anastomotic strictures (higher in LLP-group, P=0.02) and intensive care unit stay (longer in LLP-group, P=00.1). No reoperation was needed in any cases. Surgical radicality was comparable; the median of harvested lymph nodes was significantly higher in SP-group (P<0.0001). The present semiprone technique of thoraco-laparoscopic Ivor-Lewis esophagectomy is safe and feasible but may also provide some advantages in terms of lymph nodes harvested and total operation time.
