Filter by:This is a single-blind randomized controlled trial with a stratified (diabetes mellitus, non-diabetes mellitus), balanced randomization (1:1), placebo-controlled study regarding the effect of carbohydrate loading 2 hours prior to the outpatient upper endoscopic procedure. All patients who were assigned for outpatient oesophagogastroduodenoscopy (OGDS) were invited to join in this study voluntarily from January 2021 until August 2021. This study was conducted in the Endoscopy Unit, Hospital Universiti Sains Malaysia, Kubang Kerian, Malaysia. The endoscopists that performed this procedure were blinded and there was trained staff who was not involved in the study to assess the well-being score. The study protocol had been approved by the Human Research Ethics Committee of Universiti Sains Malaysia (JEPeM) with the assigned protocol code USM/JEPeM/20080414.
Helicobacter pylori (Hp) is the major cause of gastritis and gastritis-associated diseases. Detection of a regular arrangement of collecting venules (RAC) pattern in the lesser gastric curvature correlates with negative Hp status with a sensitivity and negative predictive value (NPV) higher than 90% in Asian countries. In a recent study carried out in our hospital, it has been shown that the presence of RAC pattern in the lesser gastric curvature, evaluated with high definition endoscopy, can accurately identify patients without Hp. The aim of this study is to confirm the validity of the endoscopic diagnosis of Hp infection in the West by means of the RAC pattern in a multicenter prospective study and to evaluate interobserver variability before establishing its applicability in clinical practice.
