Vietnam Association of Gastroenterology consensus for the diagnosis and treatment of functional dyspepsia.

Functional dyspepsia (FD) is a common disorder in clinical practice. It is necessary to rule out physical causes to diagnose this condition. However, the diagnosis is challenging particularly in resource-limited areas. The aim of this consensus is to update international and regional guidelines on the management of FD. The consensus panel included 32 experts from major Vietnamese universities and institutes. This consensus study was conducted using the Delphi method. The grade of recommendation and level of evidence were assessed using the Grading of Recommendations, Assessment, Development, and Evalua-tion system. The consensus level was defined as ≥80% for agreement on the proposed statements. The expert panel approved 14 statements after two rounds of voting, which were related to two sections: (1) diagnostic tests for FD and (2) treatment of FD. This consensus is expected to help physicians in identifying and managing FD appropriately in daily clinical practice and to contribute FD data to Asian regions.
