Magnifying NBI Endoscopy for Gastric Condition

All genders
Recently, the improved resolution with standard endoscopy allows the close observation of highly inflamed gastric mucosa without a magnifying view. In a previous study, the investigators established the endoscopic classification of H. pylori-infected stomach by non-magnifying standard endoscopy. One normal RAC pattern and three types of abnormal patterns were observed. Overall diagnostic accuracy for predicting H. pylori-infection was 91.6%. However, there is no comparison study predicting H. pylori-infection and precancerous gastric lesions between standard and magnifying endoscopy.
