Anal fistula - Wikipedia
This year-old man presented with a very painful infection. There was a large abscess which was easily palpable with surrounding cellulitis. It clearly needed incision so he was admitted for this to be done under general anaesthetic. There was no obvious underlying cause, such as inflammatory bowel disease or diabetes. Following drainage, the abscess cavity required regular dressing but healed well.
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. The treatment of peri-anal fistulas is difficult and always multidisciplinary. The European guidelines recommend combined surgical and medical treatment with biologic drugs to achieve best results. Several different surgical techniques are currently employed.
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.
