title: Unusual cause of neonatal rectal bleeding: colonic intramural haematoma.
abstract: Bright rectal bleeding in a neonate is most commonly due to necrotising enterocolitis, gastrointestinal infection or cows milk protein intolerance. We present here an infant who developed PR bleeding after cardiac surgery. Bleeding persisted despite presumptive treatment for the most common causes. A colonic intramural haematoma was identified on colonoscopy most likely related to anticoagulation in the setting of cardiac surgery.
