The Minimal Standard Terminology (MST) for gastrointestinal endoscopy is the result of continuing work by WEO, the European Society of Gastrointestinal Endoscopy (ESGE), the American Society of Gastrointestinal Endoscopy (ASGE) and a large international group of collaborators. The Documentation & Standardization Committee led by co-chairs, Thomas de Lange (Norway) and Koji Matsuda (Japan) has been responsible for this task, which has resulted in the present version, MST 3.0. While the original ideas of Prof Maratka, ESGE, ASGE, and the Gaster project have been retained, some modifications were made in a current revision.

The first MST was created more than 25 years ago to standardize terminology in GI endoscopy, and has been the gold standard platform for the multitude of endoscopic report generators for many years.

However, version 3, the most recent iteration, was released more than 10 years ago, in 2008. Since then there have been many advances, especially regarding new classifications for diagnostic procedures and the therapeutic procedures such as interventional EUS.

The team is working hard to prepare version 4, which will meet the needs of modern practice.

The Committee has carried out the first round of a survey regarding their proposals for updated terms. Voting on these proposals during the next 2 months is planned, in the hope of completing the work by the end of this year.

In addition, it was decided to draw up a special MST for capsule endoscopy.

We are very happy to receive comments and suggestions from WEO members. Please send an email to secretariat@worldendo.org.
