Relationship between the anesthesia type and prolonged PLOS (days)

Outcome	Prolonged PLOS (days) OR (95% CI) P value
Anesthesia type	Crude model	Model I	Model II
GA	Reference	Reference	Reference
E-GA	1.54 (0.86, 2.74) 0.1456	1.54 (0.86, 2.78) 0.1473	1.60 (0.80, 3.23) 0.1841

Abbreviations: PLOS postoperative length of stay, OR odds ratio, CI confidence interval, GA general anesthesia, E-GA combined epidural-general anesthesia

Model I adjusted for age and sex

Model II adjusted for history of smoking, postoperative ICU admission, respiratory failure, lung infection, surgical site infection, and anastomotic leakage
