Advantages of the prone position for minimally invasive esophagectomy in comparison to the left decubitus position: better oxygenation after minimally invasive esophagectomy

Purpose The aim of this retrospective study was to evaluate whether minimally invasive esophagectomy (MIE) in the prone position has advantages over the left decubitus position. Method A total of 110 consecutive patients with esophageal cancer who had undergone MIE were included in the analysis. The clinical outcomes were compared between 51 patients treated in the prone position (prone group) and 59 patients treated in the left decubitus position (LD group). The main outcome was postoperative respiratory complications and postoperative oxygenation [arterial oxygen pressure/fraction of inspired oxygen ( P / F ratio)]. The secondary outcomes included the length of the operation, blood loss, number of dissected lymph nodes, postoperative morbidities and mortality. Results The P / F ratio after the operation was significantly higher in the prone group (0 h: P = 0.01, 12 h: P
