ASGE Annual Postgraduate Course: Clinical Challenges and Real-Time Decision Making in GI Endoscopy (Live and Virtual) | May 2023-Endoscopic Classification of Barrett’s Esophagus

Video Transcription

Video Summary

The video segment discusses the classification and measurement of Barrett's esophagus. It explains that short Barrett's is less than 3 cm in length, while long Barrett's is greater than 3 cm. However, it is now known that both types can progress to adenocarcinoma. The Prague C and M classification, proposed at a gastroenterology meeting in Prague, was designed to standardize and improve measurement accuracy. The C represents the distance from the gastroesophageal junction to the proximal margin of the circumferential Barrett's epithelium, while the M represents the distance to the longest tongue-like segment. The video provides an illustration to clarify the classification, explaining that the M measurement includes the entire length of Barrett's esophagus. Islands of Barrett's esophagus are not considered in this classification. An example is given, showing a P2M6 classification for a case with a circumferential length of 2 cm and a maximum length of 6 cm. Previously discussed, the example would be classified as C2M4. No credits were given in the video.
