ONE CASE OF RECTAL MUCOSAL PROLAPSE SYNDROME SHOWING CIRCUMFERENTIAL FLAT REDDENING

Abstract

The patient was a 35-year-old man who visited our department with a chief complaint of abdominal fullness. The patient had been suffering from symptoms of irritable bowel syndrome for the last 10 years ; in addition, he had habitual straining for more than 10 minutes at the time of defecation. Endoscopy of the lower GI tract demonstrated circum-ferential zonal redding in the rectum about 5 cm from the anal edge. Biopsy revealed fibromuscular obliteration. The diagnosis of recal mucosal prolapse syndrome was estab-lished. Ultrasonic endoscopy demonstrated hyperplasia of the third layer with a micro-scopic lesion within the third layer.
