World Gastroenterology Organisation

Global Guardian of Digestive Health. Serving the World.


Guidelines Committee

The Global Guidelines Committee is established to produce Guidelines written and published with a global focus and from a viewpoint of application around the world, unlike other medical guidelines which are targeted to specific regions or countries.

Each Guideline includes reference to other relevant guidelines which are identified, summarized and republished or cited by WGO for the benefit of the practitioner. The WGO Guidelines are unique in that they utilize “Cascades” which provide various diagnosis and evidence-based treatment options that are scalable to available local resources and infrastructure in countries with varying resources. Each Guideline review team includes non-Western experts with direct knowledge of conditions in various regions around the world to ensure the applicability of the procedures under a variety of circumstances.
