Background: Helicobacter pylori can colonize the submucosal layer as well as the mucosa in the stomach. Inflammation and erosions cause both mucosal and submucosal thickening in patients with Helicobacter pylori gastritis. Elastography is a method for measuring the elasticity and hardness of tissues by visualization of their response to the applied force. Hard tissues respond to applied compression differently compared to soft tissues. Hard tissues displace as a whole without deforming as opposed to soft tissues. In this study, we investigated the diagnostic performance of transabdominal ultrasound elastography in detecting Helicobacter pylori gastritis in children. Methods: Nineteen children (group 1) with Helicobacter pylori gastritis, 33 children (group 2) with Helicobacter pylori (-) gastritis and 37 healthy children (group 3) were included the study. These groups were compared in terms of their strain index values. Ultrasonographic examinations were performed with a single transducer at 1.8–6.2 MHz frequency range. Results: Both group 1 and 2 had significantly higher strain index values compared to the control group (2.7, 2.2 and 1.4 respectively). Additionally, the mean strain index value was significantly higher in group 1 compared to group 2. Conclusion: Transabdominal ultrasound elastography has diagnostic value in differentiating Helicobacter pylori (+) gastritis from Helicobacter pylori (-) gastritis as well as in the diagnosis of gastritis in children.
