Perianal Crohn's disease.

Crohn's disease is commonly complicated by perianal manifestations. The surgeon plays a pivotal role in caring for these patients; a detailed history along with a thorough clinical exam provides the treating physician with invaluable information upon which to base further investigations and management decisions. Other than abscess drainage, medical management to control proximal disease often precedes any surgical attempt to cure the disease. Surgical interventions are indicated in selective patients, but are often complicated by poor wound healing and recurrences. A sizable percentage of these patients may need a proctectomy.
