Inflammatory bowel disease: the view of the surgeon.

Despite advances in medical therapy, surgery is required in approximately 30-40% of patients with ulcerative colitis (UC) and 70-80% of patients with Crohn's disease (CD) at some point during their lifetime. For patients with UC, surgery may be curative, whereas recurrence of CD following surgery is common due to the potentially pan-enteric distribution of the disease. As a result, the indications and surgical management of the disease may be quite different. For UC, the surgeon is involved in the identification of new cases, management of severe disease, recognition of dysplasia and restorative proctocolectomy. Most of the advances in surgery for UC have been in novel techniques relating to the ileal pouch-anal anastomosis, which can now be performed safely for UC with a 10% pouch failure rate long term. For CD, the surgeon is involved in the management of small bowel and ileo-colonic disease, Crohn's colitis and perianal disease. Advances in the surgical management of CD include strictureplasty for extensive small bowel disease, laparoscopic ileo-caecal resection and a combined medical and surgical approach to perianal disease. For both CD and UC close liaison between the gastroenterologist and colorectal surgeon is essential.
