Thailand Consensus on Helicobacter pylori Treatment 2015

  • Published : 2016.05.01

Abstract

Management of Helicobacter pylori infection is an important aspect of many upper gastrointestinal tract diseases, such as chronic gastritis, peptic ulcer disease, gastric cancer and mucosa-associated lymphoid tissue (MALT) lymphoma. The Thailand Consensus on H. pylori treatment 2015 consisted of 22 national experts who took active roles, discussed all important clinical information and investigated clinical aspects in four workshops, focuising on: (1) Diagnosis (2) Treatment (3) Follow-up after eradication and (4) H. pylori infection and special conditions. Experts were invited to participate on the basis of their expertise and contribution to H. pylori works and/or consensus methodology. The results of each workshop were taken to a final consensus vote by all experts. Recommendations were developed from the best evidence and availability to guide clinicians in management of this specific infection associated with variety of clinical outcomes.
