Currently 4 surgical techniques are performed for transthoracic esophagectomy (open esophagectomy (OE), hybrid esophagectomy (HE), conventional minimally invasive esophagectomy (MIE) and robot assisted minimally invasive esophagectomy (RAMIE). Aim of this study was to compare these 4 different esophagectomy approaches regarding postoperative complications and short term oncologic outcomes. Between 2008 and 2019, consecutive patients who underwent esophagectomy with gastric conduit reconstruction were included in this single center study. The primary outcome of this study was the incidence of postoperative complications. Overall 422 patients (OE (n = 107), HE (n = 101), MIE (n = 91) and RAMIE (n = 123)) were evaluated. Uncomplicated postoperative course was observed in 27% (OE), 34% (HE), 53% (MIE), and 63% (RAMIE) of patients (p < 0.001). Pulmonary complications were observed in 57% (OE), 44% (HE), 28% (MIE), and 21% (RAMIE) of patients (p < 0.001). Cardiac complications were present in 25% (OE), 23% (HE), 9% (MIE), and 11% (RAMIE) of patients (p < 0.001). MIE and RAMIE were associated with fewer wound infections (p < 0.001). Median hospital stay after MIE (13 days) and RAMIE (12 days) was shorter compared to OE (20 days) and HE (17 days) (p < 0.001). A median number of 21 (OE), 23 (HE), 23 (MIE), and 31 (RAMIE) lymph nodes was harvested (p < 0.001). Total minimally invasive esophagectomy (MIE, RAMIE) was associated with a lower overall, pulmonary, cardiac and wound complication rate as well as a shorter hospital stay compared to open or hybrid approach (OE, HE). RAMIE resulted in higher lymph node harvest than MIE.
