A
- Mostly in the caecum and ascending colon
- Probably a combination of multiple factors
- Age-related degeneration of vessel walls
- AV shunting from chronic obstruction of submucosal veins due to repeated episodes of high intraluminal pressures
3

A
- End-stage renal disease

- Scleroderma
4
Q
What are the findings on history/examination likely in angiodysplasia?

5
Q
What are the principles of management of aniodysplasia?
A
- Active haemorrhage
- Endoscopy, then mesenteric angiogram, leading to colonoscopy and adrenaline/cautery/resection
