Toxic megacolon

Alternative Names:

Toxic dilation of the colon; Megarectum
Treatment:

The objective of treatment is to reduce the size of the bowel and to prevent swallowed air from further distending the bowel. If this is not achieved or the patient does not improve within 24 hours, a colectomy (surgical removal of all or part of the colon) is indicated.

Fluid and electrolyte replacement help to prevent dehydration and shock.

Use of corticosteroids maysuppress the inflammatory reaction in the colon if megacolon has resulted from active inflammatory bowel disease. Antibiotics may be given to prevent sepsis (a severe infection).

Expectations (prognosis):

If the condition does not improve, there is a significant risk of death. In this situation, a colectomy is usually required.

Complications:

Sepsis
Shock
Perforation of the colon
