Sixth Chinese National Consensus Report on Management of Helicobacter pylori Infection (Treatment Excluded) / 胃肠病学

ABSTRACT

The sixth national consensus conference on the management of Helicobacter pylori (Hp) infection organized by Helicobacter pylori Study Group of Chinese Society of Gastroenterology was held at Nanchang, Jiangxi Province on December 17, 2021. Experts in the field of Hp research and gastroenterology attended the meeting and several consensus preparatory groups were established to draft the related statements. The level of evidence was evaluated using the 2011 Oxford Centre for Evidence⁃Based Medicine Levels of Evidence. The strength of recommendation was graded by GRADE (grading of recommendations assessment, development, and evaluation) system. The Delphi method using an anonymous electronic system was adopted to develop the consensus of relevant statements. The statements initially reached a consensus were discussed repeatedly in the conference and the experts voted for the final consensus. The consensus contents contained a total of 30 statements and were divided into 4 parts, including (a) diagnosis of Hp infection, (b) indications for Hp eradication, (c) Hp and gastric cancer, and (d) Hp and gastrointestinal microbiota.
