Fistula in Ano

Fistula in Ano - Fistula in Ano is abnormal communication between anal canal and perianal skin lined by granulation tissue, secondary tracks may be multiple. Etiology - Crypto Glandular Hypothesis -Most of the fistulas originate from anal gland infections. Anal cryptic glands lie between the internal and external anal sphincter and drain into the anal canal.
The Cryptoglandular hypothesis states that an infection begins in the anal canal glands and progresses into the muscular wall of the anal sphincters to cause an anorectal abscess.Fistula in Ano can also develop secondary to trauma, malignancy, radiation, tuberculosis, inflammatory bowel disease etc.
