Problems related to colonic anastomosis heating constitute the major morbidity in colorectal surgery. Patients without appropriate nutritional support are at higher risk of postsurgical complications, mainly due to reduced wound heating. Therefore, we investigated the effect of early and late postoperative total enteral. nutrition (TEN) and glutamine addition on colon anastomosis heating using tight microscopy and immunohistochemistry (IGF-I immunolabelling). In this study, 40 Wistar-albino rats underwent distal. left colonic transection and anastomosis. The rats were then divided into four groups given different diets: delayed total enteral. nutrition (dTEN; beginning 3 days postoperatively), delayed TEN with added glutamine (dTEN+ Glutamine), early TEN (eTEN; beginning within 6 h postoperatively), and early TEN with added glutamine (eTEN+Glutamine). Colon segments, including the anastomosis, were excised 7 days postoperatively and evaluated histopathologically for inflammation, mucosal heating, submucosal-muscular layer repair, the amounts of necrosis and vascularisation and immunohistochemically for IGF-I labelling. The inflammation and necrosis scores in the dTEN and dTEN+Glutamine groups were significantly greater than in the eTEN and eTEN+GLutamine groups. The IGF-I immunoreactivity increased in the eTEN, eTEN+Glutamine, and dTEN+Glutamine groups compared to dTEN (p
