Abscess: An abscess is a collection of pus caused by bacterial infection.
Bowel Perforation: severe inflammation may result in a hole developing anywhere along the gastrointestinal tract which can lead to sepsis; it usually requires immediate surgical attention.
Fistulizing disease: According to studies, 35-50% of Crohn’s patients develop at least one fistula. Fistulae are complications of Crohn’s that cause damage to the lining of the intestines and result in abscesses and abnormal tunnels between the intestine and another organ (e.g., bladder), or out onto the skin. Many fistulae can develop to the anal region and genitourinary areas (scrotum, penis, vulva, vagina, etc.), and are often referred to as perianal disease. **need a good diagram of a fistula**
Stricturing disease: Another complication of Crohn’s is an intestinal stricture, which is a narrowing of the intestine from inflammation. It prevents stool from passing through and can result in intestinal blockages and sometimes bowel perforations. **need a good diagram of a stricture and how it narrows the bowel**
