There is growing focus on the relationship between surgical start time and postoperative outcomes. However, the extent to which the operation start time affects the surgical and oncological outcomes of patients undergoing esophagectomy has not previously been studied. The purpose of this retrospective study was to investigate the potential effect of surgical start time on the short- and long-term outcomes for patients who underwent thoracoscopic-laparoscopic McKeown esophagectomy. From September 2009 to June 2019, a total of 700 consecutive patients suffering from esophageal cancer underwent thoracoscopic-laparoscopic McKeown esophagectomy in the Department of Thoracic Surgery at Daping Hospital. Among these patients, 166 esophagectomies were performed on the same day and were classified as the first- or second-start group. Patients in the first-start group were more likely to be older than those in the second-start group: (64.73 vs. 61.28, P = 0.002). In addition, patients with diabetes mellitus were more likely to be first-start cases (8.4 vs. 1.2%). After propensity score matching (52 matched patients in first-start cases and 52 matched patients in second-start cases), these findings were no longer statistically significant. There was no difference in the incidence rate of peri- or postoperative adverse events between the first- and second-start groups. The disease-specific survival rates and disease-free survival rates were comparable between the two groups (P = 0.236 and 0.292, respectively). On the basis of the present results, a later start time does not negatively affect the short- or long-term outcomes of patients undergoing minimally invasive McKeown esophagectomy.
