Definition
Colitis is colonic inflammation; endoscopy describes appearance and distribution but not necessarily the cause.
Examination or reading method
Describe each segment, rectum and transition areas; assess infection risk and obtain indicated samples.
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.
Associated findings
Relate appearance to diarrhoea, rectal bleeding, pain and histology; assess extraintestinal features according to context.
Red flags
Substantial bleeding, fever, tachycardia or distension warrants assessment of clinical severity.
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.
