Condition of the rectal closure system in ostomy patients

Abstract

Aim of the study. The main idea of the study is to study changes in the functional activity of the rectum closure system in patients with intestinal stomas.Materials and methods. A single-center retrospective and prospective analysis of the results of changes in the function of the rectum closure system in 83 patients before reconstructive operation was performed. For the period from 2016-2018, 42 (50.6 %) men and 41 (49.4 %) women were examined, the average age in the group was 51.8 ± 12.6 years. A statistical analysis of the influence of various factors on the functional state of the obturator apparatus of the rectum was performed.Results and discussion. In all the examined patients, before the intervention, a decrease was found in the indicators characterizing the functional state of the anal closure system: average (ARP) rest anal pressure and maximum squeezing anal pressure (MSP). A statistically significant direct relationship was found between high degree of tightness between the degree of impaired function of the rectum closure system and the age of the patient (Rxy = 0.76, p = 0.005), and the duration of wearing the stoma (Rxy = 0.82, p = 0,0072). The mathematical model of the dependence of the degree of insufficiency of the anal sphincter on the age of patients and the duration of stoma wearing is characterized by a correlation coefficient Rxy = 0.72, a significance coefficient p <0.001.Conclusions. The results of analysis make it possible to assess the condition of the rectal closure system before reconstructive intervention and identify factors affecting it.
