Prague C and M Classification for Barrett's Oesophagus
Standardised endoscopic description of Barrett's oesophagus extent. C = circumferential extent (cm above GOJ); M = maximum extent (cm above GOJ). Used for surveillance interval determination and dysplasia reporting. BSG 2023 and NICE NG12 guidelines use Prague C&M to guide surveillance intervals. Short-segment Barrett's: maximum extent below 3 cm; long-segment: 3 cm or above.
