AIM :To determine the beneficial effects of Glutamine, Psyllium, Short Chain Fatty Acids (SCFA), and Maharishi Amrit Kalash (MAK), in preventing the histological changes after diversion colostomy.MATERIAL AND METHODS :After ethical clearance, male wistar rats (n=40) underwent diversion colostomy. Rats were divided into five groups of 8 rats each. Each group was given, after diversion colostomy, per rectally, one of the five agents being tested as an enema (3 ml/kg/day). Group I: Normal saline. Group II: Glutamine Group III: Psyllium, Group IV: MAK. Group V: Short chain fatty acid. The rats were euthanised 45 days after performing diversion colostomy. Morphometrical analysis of defunctionalised colon was done. Statistical analysis was done using SSPS statistical analysis software.RESULTS :On comparison with Group I epithelial cell height and mucosal thickness was significantly higher in Group II. Muscularis externae thickness was significantly higher in Group III on comparison with Group I. Group V had least inflammatory changes.CONCLUSIONS :Atrophic and inflammatory changes in the diverted colon can be prevented by per rectal administration of Glutamine, Psyllium and Short chain fatty acids.
