Angiodysplasia is a condition that may cause rectal bleeding or anaemia, in which abnormal and often fragile blood vessels (vascular malformations) may bleed from time to time.


The abnormal blood vessels are typically found on endoscopy, and appear as red patches that may be actively bleeding at the time of the examination.


The blood vessels can be burnt off with Argon Plasma Coagulation, a technique that is able to burn the superficial layers with a good margin for safety.
