The assessment of endoscopic gastric atrophy (EGA) according to the Kimura-Takemoto classification has been reported to correlatewell with histological assessment. Although agreement among beginner endoscopists was less than that among experiencedendoscopists, it has been shown that agreement level could markedly improve and remained stable after proper training. Severalcohort studies have consistently shown that the severity of EGA at baseline is significantly associated with the presence of advancedprecancerous gastric lesions and gastric cancer, as well as the development of gastric cancer in future. Patients with moderate-to-severeEGA still have high risk of gastric cancer even after successful Helicobacter pylori eradication and should be candidates for gastriccancer surveillance. The assessment of EGA, therefore, could be used as a preliminary tool to identify individuals at high risk forgastric cancer. In this paper, we review the agreement on mucosal atrophy assessment between the Kimura-Takemoto classification andhistology as well as the potential application of this endoscopic classification to identify precancerous gastric lesions and gastric cancerin daily practice.

Background/Aims There have been no studies investigating the distribution of abnormal gastroesophageal flap valve (GEFV) among patients with dyspepsia, non-erosive reflux disease (NERD), and reflux esophagitis (RE) in the same set of patients. The aims of this study are to investigate (1) the association between GEFV and gastroesophageal reflux disease questionnaire (GERDQ) score, and (2) the distribution of abnormal GEFV in Vietnamese patients presenting with upper gastrointestinal symptoms. Methods Three hundred and thirty-one patients recruited in this prospective cross-sectional study were classified into 3 groups: reflux esophagitis (RE), non-erosive reflux disease (NERD) (GERDQ score ≥ 8, no endoscopic mucosal injury), and dyspepsia (GERDQ score < 8, no endoscopic mucosal injury). The GEFV was graded endoscopically according to the Hill classification. GEFV grades I and II were regarded as normal, while grades III and IV were regarded as abnormal GEFV. Results There were 215 (65.0%) patients with dyspepsia, 55 (16.6%) patients with NERD, and 61 (18.4%) patients with RE. Abnormal GEFV was an independent risk factor for GERD (OR, 2.93; CI 95%, 1.76–4.88) and RE (OR, 3.41; CI 95%, 1.78–6.53). The mean GERDQ score of patients with abnormal GEFV was significantly higher than that of patients with normal GEFV (5.7 ± 2.4 vs 4.9 ± 2.7, P = 0.011). The prevalence of abnormal GEFV gradually increased in patients with dyspepsia (27.4%), NERD (43.6%), grade A RE (56.8%), and grades B/C RE (80.0%) (P < 0.001). Conclusions Abnormal GEFV was significantly associated with high GERDQ score. Its prevalence gradually increased in patients with dyspepsia, NERD, and RE, respectively.

Background/Aims: To compare the performance of a modified Glasgow Blatchford score (mGBS) to the Glasgow Blatchford score (GBS) and the pre-endoscopic Rockall score (RS) in predicting clinical interventions in Vietnamese patients with acute nonvariceal upper gastrointestinal bleeding (ANVUGIB). Methods: A prospective multicenter cohort study was conducted in five tertiary hospitals from May 2013 to February 2014. The mGBS, GBS, and pre-endoscopic RS scores were prospectively calculated for all patients. The accuracy of mGBS was compared with that of GBS and preendoscopic RS using area under the receiver operating characteristic curve (AUC). Clinical interventions were defined as blood transfusions, endoscopic or radiological intervention, or surgery. Results: There were 395 patients including 128 (32.4%) needing endoscopic treatment, 117 (29.6%) requiring blood transfusion and two (0.5%) needing surgery. In predicting the need for clinical intervention, the mGBS (AUC, 0.707) performed as well as the GBS (AUC, 0.708; p=0.87) and outperformed the pre-endoscopic RS (AUC, 0.594; p<0.001). However, none of these scores effectively excluded the need for endoscopic intervention at a threshold of 0. Conclusions: mGBS performed as well as GBS and better than pre-endoscopic RS for predicting clinical interventions in Vietnamese patients with ANVUGIB. (Gut Liver 2016;10:375- 381)
