Overview

Except in the most severe cases, ischemic colitis is treated with supportive care. Treatment is determined by its severity and include intravenous fluids, bowel rest, nasogastric tube, and total parenteral nutrition. Patients with colonic dilatation are managed with insertion of a rectal tube or endoscopic decompression. There is no evidence about the role of anticoagulation or antiplatelet therapy. Steroids have not been shown to improve outcomes.

Medical Therapy

The medical therapy for ischemic colitis is as follows:[1][2][3][4][5]

  • Treatment is determined by its severity
    • Precipitating factors such as sepsis, hypotension, poor cardiac function, hypovolaemia and hypoxia should be addressed, and precipitating drugs withdrawn.
  • Patients with colonic dilatation are managed with insertion of a rectal tube or endoscopic decompression.
  • There is no evidence about the role of anticoagulation or antiplatelet therapy.
  • Steroids have not been shown to improve outcomes.

Intravenous Fluids

  • Fluid resuscitation
    • Intravenous fluids
    • Bowel rest
    • Nasogastric tube
    • Total parenteral nutrition if prolonged bowel rest

Optimize Cardiac Output

  • If possible, cardiac function and oxygenation should be optimized to improve oxygen delivery to the ischemic bowel.

Nasogastric Tube

Antibiotics

  • Antibiotic use in animal studies has demonstrated reduced duration and severity of ischemic colitis, and prevention of bacterial translocation through damaged mucosa.
    • A study involving dogs demonstrated reduction in vessel thrombosis and increased survival.
  • The role of antibiotic therapy in humans requires further research.

Contraindicated medications

Ischemic colitis is considered an absolute contraindication to the use of the following medications:
