Turkish journal of medical sciences 2024Intestinal neomucosa formation is a technique defined for the treatment of short bowel syndrome. This study evaluates the effect of glutamine and omega-3 fatty acids on the growth of intestinal neomucosa on the colonic serosal surface has been evaluated. Thirty-two adult male Sprague-Dawley rats were randomly divided into 4 groups: sham, control, glutamine, and omega-3. Laparotomy was performed on all groups. For rats other than the sham group, a 1-cm full-thickness incision was made 4 cm proximal to the ileocecal valve, and colonic serosal surface was sutured as a serosal patch over these openings. By using the oral gavage technique, the glutamine group was ingested with 200 mg/kg/day of glutamine, and the omega-3 group was ingested with 100 mg/kg/day of omega-3 fatty acids. At the end of 14 days, the rats were euthanized, blood specimens were collected, and intestinal segments, including serosal patches, were excised. Transforming growth factor-beta was significantly lower in the glutamine group compared to the control group. Similarly, fibroblast growth factor-2 was significantly lower in the glutamine group compared to the sham group. Intestinal neomucosa formation was observed in 100% of rats in the glutamine group. In the control and omega-3 groups, intestinal neomucosa formation was observed in 57.1% and 60% of rats, respectively. The inflammatory response, granulation tissue formation, and fibroblastic activity were more severe in the rats of the glutamine and omega-3 groups. The intestinal neomucosa formation is an experimental technique, and both glutamine and omega-3 fatty acids have the potential to positively affect inflammatory response, granulation tissue formation, and fibroblastic activity. Specifically, glutamine has a favorable effect on intestinal neomucosa formation. © TÜBİTAK.
