Is Early Enteral Nutrition Initiated Within 24 Hours Better for the Postoperative Course in Esophageal Cancer Surgery?

Abstract

BACKGROUND Early enteral nutrition within 24 h after surgery has become a recommended procedure. In the present study, we retrospectively examined whether initiating EN within 24 h after esophagectomy improves the postoperative course. METHODS Among 103 patients who underwent thoracic esophagectomy for esophageal cancer, we enrolled the cases in which EN was initiated within 72 h after surgery. The patients were divided into two groups: EN started within 24 h (Group D1) and EN started at 24 - 72 h (Group D2-3). Clinical factors including days for first fecal passage, dose of postoperative albumin infusion, difference in serum albumin between pre- and postoperation, incidence of postoperative infection, and use of total parenteral nutrition were compared. Statistical analyses were performed by the Mann-Whitney U test and Chi square test, with significance defined as P < 0.05. RESULTS There was no significant difference between the groups in clinical factors. While pneumonia was significantly more frequent in Group D1 than in Group D2-3 (P = 0.0308), the frequency of infectious complications was comparable between the groups. CONCLUSION Initiating EN within 24 h showed no advantage for the postoperative course in esophageal cancer, and thus EN should be scheduled within 24 - 72 h, based on the patient condition.
