Ultrasonographic findings in the gall bladder in human fascioliasis.

This study included forty patients with incubating or open fascioliasis. All were subjected to repeated stool examination, serological and haematological study using IHAT in the former. Ultrasonography was done for upper abdomen stressing on gall bladder and assessing its function. Eighteen patients were diagnosed as incubating fascioliasis by positive IHAT, high eosinophilic count and negative stool examination for Fasciola eggs. No gall bladder changes could be detected by U.S. among those patients. Twenty two patients passed eggs in their stool were diagnosed as open Fasciola. Their gall bladder through U.S. revealed flukes in twelve of them. A weak gall bladder contractility was observed in 64% with open fascioliasis.
