 Abstract. A transperineal ultrasound study was performed on 56 patients who underwent abdomino-anal resection of the rectum with the descending. Defects of the internal anal sphincter were detected in 26 patients. Of these, 2 patients additionally had lesions of the external sphincter. All 26 patients with sphincter lesions had anal incontinence (5 patients ― I degree; 19 patients ― II degree; 2 patients ― III degree). Among 30 patients who had no sphincter defects with echography, only three had anal degree I incontinence. The leading cause of anal incontinence is damage to the internal sphincter of the rectum.

Кеу words: internal anal sphincter, transperineal ultrasound, anal incontinence.
