Background
The literature on oral intake after esophagectomy and its influence on anastomotic leakage and complications is sparse.
Methods
This retrospective study included 359 patients undergoing esophagectomy between January 2011 and August 2015. Three oral intake protocols were evaluated: regimen 1, nil by mouth until postoperative day (POD) 7 followed by a normal diet; regimen 2, oral intake of clear fluids from POD 1 followed by a normal diet; regimen 3, nil by mouth until POD 7 followed by a slow increase to a blended diet. The outcome endpoints were: (1) anastomotic leakage, (2) complications [severity and number described using the Dindo–Clavien Classification and Comprehensive Complication Index (CCI)] and (3) length of stay. A multivariate logistic regression model was obtained for CCI and anastomotic leakage using Wald’s stepwise selection.
Results
CCI was significantly lower in regimen 3 (16 vs. 22 and 26 in regimen 1 and 2, p = 0.027). Additionally, significantly fewer patients in regimen 3 suffered from severe complications of Dindo–Clavien grade IIIb–IV (p = 0.025). The incidence of anastomotic leakage reached its lowest in regimen 3, 2%, compared to 7–9%. Multivariate analyses revealed that high American Society of Anesthesiologist score was a predicting factor for both CCI and anastomotic leakage.
Conclusion
The study indicates that nil by mouth until postoperative day 7 followed by a slow increase to a blended diet after esophagectomy results in less severe complications and a tendency of fewer anastomotic leakages. Multiple comorbidities proved to be an important predictive factor of the postoperative course.
