Inflamed colonic mucosa · endoscopy

- Friability or bleeding
- Distribution
- Continuous or segmental
Morphological description
Record granularity, loss of markings, friability, erosions, ulcers and spontaneous bleeding; findings may coexist.
Causes and diagnostic direction
Inflammatory bowel disease, infection, ischaemia and medicines can cause colitis.
Differential diagnoses
Continuous involvement from the rectum suggests ulcerative colitis and must be distinguished from other colitides.
Pitfalls and limitations
Granularity alone does not diagnose ulcerative colitis; treatment and preparation quality alter appearance.
Take-home message
Describe inflammation and distribution, then correlate infectious, clinical and pathological evidence.
