Definitive diverticular hemorrhage: Diagnosis and management

Conclusion

The most effective way to diagnose and treat definitive TIC hemorrhage is to perform an urgent colonoscopy within 24 hours to identify and treat TIC SRH. This procedure requires thoroughly cleansing the colon first, as well as an experienced colonoscopist who can identify and treat TIC SRH to obliterate arterial blood flow underneath SRH and achieve definitive TIC hemostasis. Other approaches to early diagnosis include nuclear medicine scintigraphy or angiography (CT, MRI, or IR). However, these techniques can only detect active bleeding which is documented in only 26% of colonoscopically diagnosed definitive TIC hemorrhages. So, the expected diagnostic yield of these tests will be low. When urgent colonoscopy fails to make a diagnosis or TIC bleeding continues, TAE and/or surgery are recommended. After definitive hemostasis of TIC hemorrhage and for long term management, control of constipation and discontinuation of chronic NSAIDs and antiplatelet drugs (if possible) are recommended to prevent recurrent TIC hemorrhage.
