Enteral nutrition in postoperative rehabilitation after reconstructive esophageal and gastric surgery

Abstract

To investigate enteral nutrition as a component of postoperative rehabilitation after reconstructive esophageal and gastric surgeries. The study included 217 patients who underwent reconstructive esophageal and gastric surgeries between 2010 and 2020. In the main group (n=121), patients underwent postoperative enhanced recovery program (ERAS). Early enteral feeding including micro-jejunostomy and early oral feeding was essential for postoperative management. The control group included 96 patients who were treated in traditional fashion. The primary endpoint was length of hospital-stay (LOS) and ICU-stay. Restoration of gastrointestinal function (peristalsis, stool, oral nutrition), anastomotic leakage rate and other complications comprised secondary endpoints. Both groups did not differ by sex, age, body mass index, diagnosis and comorbidities. There was significant reduction in postoperative LOS in the ERAS group (14 (12; 15.8) and 9 (6.3; 12) days, p<0.0001). In the same group, we observed less in ICU-stay (4.7 (3.6; 5.6) and to 3.5 (2; 4) days, p<0.001), earlier recovery of peristalsis and X-ray control of anastomosis in patients with and without anastomotic leakage. Incidence of respiratory complications was lower in the ERAS group (p=0.034). Overall postoperative morbidity and mortality were similar. Early enteral and oral feeding after esophageal and gastric reconstructive surgery reduces hospital-stay and accelerates postoperative rehabilitation.
