Abstrakt:	Objective: To analyze morphological changes in wall of functioning and non-functioning small intestine in patients with preventive ileostomy and to determine histological predictors of water-electrolyte disorders. Material and Methods: We prospectively analyzed 57 patients >18 years old who underwent rectal resection with preventive ileostomy between January 2022 and November 2023. Anthropometric data included gender, age, body mass index, ECOG and ASA classes. Complications associated with large losses through ileostomy were water-electrolyte disorders, dehydration and acute renal failure with repeated hospitalization. Morphological analysis implied intraoperative full-layer biopsy of small intestine on anterior abdominal wall (ileostomy). Intraoperative biopsy of efferent and afferent loops was also carried out. Tissue samples were examined by light microscopy. We analyzed mean height of mucous membrane villi and depth of crypts, as well as their ratio. Fibrosis and swelling of submucosa were evaluated too. The results were analyzed in the SPSS Statistics 20 software. Results: Mean height of intestinal villi <465 microns ( p =0.028), ratio of their height to crypt depth <4.38 ( p =0.034) and submucosal fibrosis ( p =0.031) significantly affected malabsorption and readmission of patients. The risk of readmission was 11.5 and 5.5 times higher in univariate analysis. Multivariate analysis revealed in-hospital dehydration with resumption of infusion therapy as a predictor of readmission ( p =0.046). Conclusion: Ileostomy is a certain stress for the patient's body. Not every patient is able for adaptation. One of the adaptation mechanisms is hypertrophy of mucous membrane villi involved in digestion. This mechanism is less pronounced in patients with repeated hospitalizations. Preoperative morphological examination of ileum mucosa may be an additional objective predictor of possible complications of preventive ileostomy.
