[Ultrasonography of strangulated Richter's hernia]

Ultrasonography may show early pathological changes in an obstructed intestine and also identify abnormal structures in the abdominal wall and inguinal region. We describe a patient with intestinal obstruction due to a femoral hernia of Richter's type. The hernia was shown well by ultrasonography. Ultrasonic examination of the abdomen, including the inguinal regions, may facilitate earlier diagnosis in patients with acute abdominal disease.
