Emergency and elective surgery for small bowel Crohn's disease.

Advancements in the medical treatment of Crohn's disease have reduced the need for surgery. The indications for surgery include the failure of medical management, especially the persistence or worsening of symptoms in spite of proper treatment and complications of the disease process. These complications include intestinal obstruction, intestinal perforation with fistula formation or abscess, free perforation, gastrointestinal bleeding, urologic complications, cancer, and perianal disease. In these cases, operative therapy should be directed to the specific indication for surgery, resecting only the segment of bowel involved in the complicating process while preserving as much bowel length as possible in order to prevent short-bowel syndrome. Laparoscopic surgery has been gaining acceptance as an alternative surgical approach for properly selected patients with Crohn's disease. In conclusion, identifying the need for surgery and determining the timing of operation are the cornerstones to successful surgical management of patients with Crohn's disease.
