PURPOSE : The purpose of this study is to evaluate the role of transabdominal ultrasonography in predicting the he-morrhagic
gastritis by the evaluation of gastric wall.
MATERIALS and METHODS : Transabdominal ultrasonographic assessment of gastric wall was performed 42 patients.
Layers of gastric wall were preserved in all patients. Twenty-one patients whose gastric mucosa had diffuse
thickening more than 5mm were classified as hypertrophic group. The other twenty-one patients whose gastric
mucosa had thickness less than 5mm were classified as control group. In all 42 patients, endoscopic examina-tion
was performed and the prevalence of gastric hemorrhage was recorded. The sensitivity, specificity, positive
predictive value, and accuracy for predicting the hemorrhagic gastritis were calculated based on mucosal thick-ness.
Sixteen patients who had been diagnosed as a hemorrhagic gastritis in the hypetrophic group on endoscop-ic
examination were classified as a hemorrhagic group. The thickness of each layers in hemorrhagic and the
control group were compared using t-test and Fisher ’s exact test.
RESULTS : Using 5mm of mucosal thickness as a predictor, the sensitivity was 100%, the specificity was 80.8%, the
positive predictive value was 76.2%, and the accuracy was 88.1%. Mean thickness of mucosa in hemorrhagic
group and the control group were 9.6 ±1.6mm, and 1.4 ±0.4mm, respectively(p<0.01). Mean thickness of sub-mucosa
was 1.1 ±0.3mm in hemorrhagic group and 0.6 ±0.3mm in control group(p<0.01). The submucosal
layer was hyperechoic and well-defined in most control groups(18/21) while it was ill-defined and less
echogenic in hemorrhagic group(p<0.01).
CONCLUSION : The diagnosis of hemorrhagic gastritis can be suggested when there is diffuse thickening in the gas-tric
mueosa shile submucosa layer shows decreased echogenicits and indistinct border. This may improve the
value of sonographic evaluation. |
