Ulcerative Colitis: Follow-up
Updated: Jan 30, 2009
Intervention
Chronic ulcerative colitis is associated with an increase in the risk of carcinoma. Surgery should be contemplated only when (1) 2 biopsy samples evaluated by 2 pathologists confirm the findings, and (2) low-grade dysplasia is present in a raised lesion. As yet, no evidence suggests that regular endoscopic screening of patients with ulcerative colitis improves survival.
The treatment of ulcerative colitis relies on initial medical management with corticosteroids and anti-inflammatory agents, such as sulfasalazine, in conjunction with symptomatic treatment with antidiarrheal agents and rehydration. Surgery is contemplated when medical treatment fails or when a surgical emergency (eg, perforation of the colon) occurs. Surgical options include total colectomy (panproctocolectomy) and ileostomy, total colectomy, and ileoanal pouch reconstruction or ileorectal anastomoses. In an emergency situation, subtotal colectomy with end-ileostomy is recommended.30,31,32
Medicolegal Pitfalls
- A colonic carcinoma may easily be missed in the setting of ulcerative colitis.
Special Concerns
- Barium enema examinations should be performed with caution in patients with suspected acute ulcerative colitis.
- The examination is usually individualized. If the patient is relatively asymptomatic, a single-contrast enema may suffice. However, if the patient is hospitalized because of an acute exacerbation, it may be best to avoid a barium enema.
- For patients with chronic ulcerative colitis, if bowel preparation is needed at all, only a mild laxative may suffice. With active disease, bowel perforation may occur, and bowel gas may extravasate into the portal venous system without an obvious perforation.
- A careful double-contrast barium enema without bowel preparation may be performed in a chronic setting.
- Massive colonic hemorrhage, toxic megacolon, and perforation are known complications of ulcerative colitis.
