Abstract
Fistulization is one of the major troublesome issues of Crohn’s disease (CD). Fistulas are abnormal tracts formed between the gut and the skin, between the gut and an abscess cavity, or between the gut and other hollow structures, including the vagina. Fistulas arises from ulcers that progress to deep transmural fissures which then eventually penetrate other structures or open into another organ. They are classified as internal or external depending on where they terminate. Internal fistulas are enteroenteric, gastrocolic, enterovaginal, and enterovescical; external fistulas are enterocutaneous, colocutaneous, or perianal.
