Crohn Disease
Crohn disease is a chronic, recurrent, inflammatory disease of the GI tract
that may affect any segment from mouth to anus. Crohn disease has a propen-
sity for the ileum and proximal colon (see Table 11.3). Incidence is higher
among Ashkenazi Jews, smokers, and those with a family history. All layers of
the bowel wall are involved, and the disease may extend to mesenteric lymph
nodes. The disease is discontinuous, with skip areas that are free of ulceration.
Deep ulcerations of the bowel wall →fistulas and abscesses.
SYMPTOMS
Abdominal pain, anorexia, diarrhea, fever, weight loss, malaise, extra-intestinal
complications
EXAM
Abdominal tenderness, abdominal mass, anal fissures, fistulas
ABDOMINAL AND GASTROINTESTINAL
EMERGENCIES
Eighty percent of ZES is
sporadic, whereas 20% is
associated with multiple
endocrine neoplasia type 1
(MEN 1).
Twenty-five to thirty percent of
patients with Crohn disease
will manifest extraintestinal
complications.
