Comparative assessment of morphometric parameters of structural elements of crypts of the cecum using surgical threads polyglactin-910 and polycaprolactone modified with l- arginine in the experiment

Abstract

The article presents a research study conducted to comparatively examine the effects of synthetic absorbable polyglactin-910 sutures and a novel suture material, polycaprolactone modified with L-arginine (PCL-MA), on the morphometric parameters of the crypts in the mucosa of the cecum under experimental conditions. Surgical interventions were performed on 65 sexually mature outbred domestic rabbits aged 9-10 months and weighing (2.62±0.21) kg, which were divided into three groups: control and two experimental groups (the first one using PG-910 surgical thread and the second one using surgical thread PCL-MA). After the surgical intervention, the condition of the wound and the formed scar were studied on days 3, 7, 14, 21, 30, and 60. The morphometric method was used to analyze quantitative changes in the structural components of crypts in the cecum's perivulnar area in the experiment's dynamics. Statistically, the reliability of these quantitative changes was established. As a result of the study, it was found that when PCL-MA is used for suturing a wound defect, the functioning of the structural components of the crypts in the mucosa of the perivulnar area of the cecum is faster on average by 7 days than when using PG-910.
