[Ultrasonography in differential diagnosis of recurrent abdominal pain in children].

The authors relate the data obtained during echographic examination of 863 children suffering from gastric pains. Proceeding from the clinical and laboratory data the early topical diagnosis of the causes of the painful syndrome was impeded. Use was made of ultrasonography of the gallbladder along with its function estimation, of the intra- and extrahepatic bile ducts as well as of the liver and pancreas. A study was made of correlations between the echographic signs of the microscopic and biochemical indicators of the bile and the status of the duodenal mucosa (according to esophagogastroduodenoscopy). The data obtained demonstrate great potentialities of echography in differential diagnosis of gastric pains in children.
