The key steps are:
- Identify the gastro-esophageal junction as at the tops of the gastric mucosal folds
- If hiatus hernia is present, do not mistake the diaphragmatic hiatal impression for the gastro-esophageal junction
- For circumferential columnar-appearing mucosa above the gastro-esophageal junction define this extent in centimetres above the gastro- esophageal junction:
– report as the C value
- For any tongue-like areas of columnar-appearing mucosa, measure the Maximum extent in centimetres above the gastro-esophageal junction:
– report as the M value
The IWGCO has produced a DVD which presents background to the C&M Criteria, including an annotated video clip that explains the Criteria, and endoscopic video clips designed to build experience in the use of the Criteria.
