The first manifestation of the disease is often in the peri-anal region, which can occur years before a diagnosis, particularly in CD affecting the colon and rectum.

Anal fistula - Wikipedia
Anal fistula is a chronic abnormal communication between the epithelialised surface of the anal canal and usually the perianal skin. They can form when anal abscesses do not heal properly. Anal fistulae originate from the anal glands , which are located between the internal and external anal sphincter and drain into the anal canal. The tract formed by this process is a fistula. Abscesses can recur if the fistula seals over, allowing the accumulation of pus.

The anatomical anal canal extends from the perineal skin to the linea dentata. Surgically, the anal canal extends from the perineal skin to the anorectal ring. This is the circular upper border of the puborectal muscle which is digitally palpable upon rectal examination. The anorectal ring lies approximately ,5 cm above the linea dentata. The total length of the surgical anal canal is about cm.
