Abstract

Abstract:

A colorectal polyp is any protruding lumen of the rectum. Anal fistula is a granulomatous canal that is between anal canal or rectum and perianal skin, consisting of three parts: primary inner mouth, fistula, and secondary outer mouth. As separate diseases, there is no correlation between the two diseases. In rare cases, when the fistula is directly connected to the rectum through the levator anal musle (extrasphincteric fistula), the inflammatory stimulation may cause the proliferation of rectal polyps. It′s a misdiagnosed report of rectal polyps secondary to anal fistula (intersphincteric fistula) .

Key words: Polyps, Anal canal, Colorectal polyp, Inflammatory polyp, High intersphincteric fistula
