Endoscopic Kyoto and Kimura-Takemoto Classifications Are Comparable in Predicting High-Risk Gastric Precancerous Lesions.

Introduction: Severe and extensive gastric atrophy, extensive or incomplete gastric intestinal metaplasia, and gastric dysplasia are considered high-risk gastric precancerous lesions (HGPLs). Endoscopic findings based on the endoscopic Kyoto classification (EKC) and the Kimura-Takemoto classification (KTC) have been reported to be significantly associated with HGPLs. This study aimed to compare these two classifications in predicting active Helicobacter pylori (H.

Overlap of Gastroesophageal Reflux Disease and Functional Dyspepsia and Yield of Esophagogastroduodenoscopy in Patients Clinically Fulfilling the Rome IV Criteria for Functional Dyspepsia.

Aim: To assess (1) the overlap rate of gastroesophageal reflux disease (GERD) and functional dyspepsia (FD) and (2) the yield of esophagogastroduodenoscopy in patients clinically presenting with FD.

Materials And Methods: Outpatients aged ≥18 years with typical reflux symptoms ≥2 times a week or clinically fulfilling the Rome IV criteria for FD were recruited and underwent esophagogastroduodenoscopy. GERD was classified into non-erosive reflux disease (NERD) and erosive reflux disease (ERD), and FD was classified into epigastric pain syndrome and postprandial distress syndrome.

Performance of chromoendoscopy and narrow-band imaging in the diagnosis of gastric intestinal metaplasia.

Background/aims: Chromoendoscopy and narrow-band imaging (NBI) have been reported to aid in the diagnosis of gastric intestinal metaplasia (GIM). This study aimed to assess the diagnostic validity of chromoendoscopy combined with NBI in the diagnosis of GIM in Vietnamese.

Methods: A cross-sectional study was carried out on patients with dyspeptic symptoms who underwent esophagogastroduodenoscopy (EGD) at the University Medical Center at Ho Chi Minh City.
