Prague C&M criteria
Gastroenterology and hepatology
Also known as: Prag-C&M-Klassifikation · Prague-C&M-Kriterien · Prag C&M kriterleri · Prague C&M criteria (endoscopic extent of Barrett's oesophagus)
What it is for
Endoscopic system for recording how far a columnar-lined (Barrett's) segment extends above the gastro-oesophageal junction (GEJ), measured in centimetres.
Classification
| Category | Description |
|---|---|
| Landmark | the GEJ is taken as the upper end of the gastric folds |
| C | circumferential extent: length of the segment that is columnar-lined around the whole circumference above the GEJ |
| M | maximum extent: length to the highest point of columnar mucosa above the GEJ, including tongue-like projections |
| Notation | written as C and M in cm, e.g. C2M5 = 2 cm circumferential and 5 cm maximum extent |
| Limit | agreement between endoscopists is good for longer segments and poorer for very short segments (under 1 cm). |
