Abstract

Background: Anatomical esophageal position may affect the short-term outcomes after minimally invasive esophagectomy (MIE). A previous single-institutional retrospective study suggested that the presence of a left-sided esophagus (LSE) made MIE more difficult and increased the incidence of postoperative complications. Methods: The current study was a multicenter retrospective study of 303 patients with esophageal cancer who underwent MIE at six esophageal cancer high-volume centers in Kyushu, Japan, between April 2011 and August 2016. The patients were divided into the LSE (66 patients) and non-LSE groups (237 patients) based on the esophageal position on computed tomography images obtained with the patients in the supine position. Results: Univariate analysis showed that patients with LSE were significantly older than those with non-LSE (69 ± 8 vs. 65 ± 9 years; P = 0.002), had a significantly greater incidence of cardiovascular comorbidity (65.2% vs. 47.7%; P = 0.013), and a significantly longer operating time (612 ± 112 vs. 579 ± 102 min; P = 0.025). Logistic regression analysis verified that LSE was an independent risk factor for the incidence of pneumonia (odds ratio 3.3, 95% confidence interval 1.254–8.695; P = 0.016). Conclusions: The presence of a LSE can increase the procedural difficulty of MIE and the incidence of morbidity after MIE. Thus, careful attention must be paid to anatomical esophageal position before performing MIE.
