Application of gastroscope and Doppler ultrasonography in early diagnosis of abdominal Henoch-Schonlein purpura

Abstract:

Objective：To analyze the characteristics of gastroscope and Doppler ultrasonography in the abdominal type Henoch-Schonlein purpura（HSP） and to investigate its clinical value for early diagnosis. Methods：Retrospective review was made on the gas－troscope and Doppler ultrasonography features of 32 children with abdominal type HSP who had been hospitalized from Januanry 2010 to October 2013. Gastroscope and Doppler ultrasonography were performed on all patients. All cases had acute abdominal pain without cutaneous purpura before gastroscope and doppler ultrasonography. Results：Abnormal finding of gastroscope was observed in 29 cases（90.6%）. The gastroscopic characteristics of stomach and duodenal mucous were congestion，swelling，hemorrhage，erosion and even ucler. Mucosal lesions became more serious in the descending duodenum. Abnormal finding of Doppler ultrasonography was ob－served in 25 cases（78.1%）. The characteristics of the injured wall was single or multiple areas of intestinal wall thickening with plenty of blood flow. Of the 35 children，23（71.9%） had both gastroscope and Doppler ultrasonography abnormal findings；cutaneous purpu－ra appeared on（9.780±3.190） d after abdominal pain；imaging results were obtained on（6.130±1.914） d after abdominal pain，for－warding clinical diagnosis of HSP for 3.65 d（t=9.23，P<0.01）. Conclusion：Both gastroscope and Doppler ultrasonography abnormal findings are common in HSP. Gastroscope combined with doppler ultrasonography is useful for early diagnosis and treatment of ab－dominal type HSP effectively.
