Answer

Microperforation typically occurs into other segments of bowel, leading to fistulae, or into areas such as the retroperitoneum, resulting in abscess formation. Perianal and perirectal fistulae occur in approximately 20-23% of individuals. Other complications of fistulizing disease include enterovesical, enterocutaneous, and rectovaginal fistulae, as well as extension into muscle in severe progressive cases.
