Clinical review of Crohn's disease.

PURPOSE: This clinical review presents proposed theories regarding the etiology of Crohn's disease (CD), the pathophysiology of the disorder, and current diagnostic methods.

DATA SOURCES: Pertinent publications in the literature, the Crohn's and Colitis Foundation web page, and relevant texts regarding pathophysiology of the gastrointestinal system.

CONCLUSIONS: CD can be a devastating disease and difficult to diagnose. The advanced practice nurse (APRN) should be aware of the etiology, pathophysiology, diagnostic methods, and current treatment options of this disorder.

IMPLICATIONS FOR PRACTICE: In collaboration with a gastroenterologist, APRNs can provide much needed information to the patient with CD. Practice recommendations include patient education, pain management, and support for quality of life issues.
