Clinical and Morphological Condition of Strictures of the Anal Canal

Abstract

Anal stricture disease occupies a leading position among complications after surgical operations in the perianal areas. The main causes of anal and rectal strictures are surgical trauma, inflammatory bowel diseases, infections and fibrosis, sexually transmitted diseases, tuberculosis, and chronic laxative abuse. Morphologically, with strictures around the anus, scar growths, deformation of the walls of venous vessels, and inflammatory infiltrates in the interstitial tissue are revealed. The morphological picture of a scar lesion in the anorectal area makes it possible to assess the maturity of the pathological connective tissue and determine the treatment tactics for this process.
