Application of Digestive Endoscopy in Diagnosis of Helicobacter Pylori Infection / 中国医学科学院学报

ABSTRACT

Helicobacter pylori (Hp),a proven pathogen of digestive disease,is closely associated with gastrointestinal diseases including peptic ulcer,chronic active gastritis,stomach cancer,and stomach-associated lymphoid tissue lymphoma. Thus,precise and timely diagnosis of Hp is of great significance. In addition to C or C breath test,rapid urease test,and other commonly used Hp diagnosis methods,some new endoscopic techniques such as magnifying endoscopy,narrow-band imaging,confocal laser endomicroscopy,Fuji intelligent chromoendoscopy,and I scanning have been used for the direct observation of the fine-structure of stomach with Hp infection or for the identification of living Hp. This article reviews the application of digestive endoscopy in the diagnosis of Hp infection.
