In the presence of an inguinal hernia, ultrasound needs to check the location of the groin, the anterior abdominal wall, above the inguinal ligament. The location of the greater omentum, sigmoid colon, and cecum of the abdomen also needs to be examined. The anatomical location of the inguinal canal corresponds roughly to the space between the internal oblique muscle, the lower edge of the arch of the transversus abdominis muscle and the inguinal ligament. In the presence of an inguinal hernia, the basic clinical manifestation is a prominent mass in the inguinal region. On ultrasound, a defect in the abdomen of the inguinal region, communicating with the abdominal cavity through the inguinal canal, can be visualized with defects of varying diameters and sizes; the extent of the mass increases with increasing abdominal pressure, and significant bowel movements are seen within. The abdominal contents, such as the greater omentum and cecum, should also be examined. If the hernia contents are the greater omentum, the mass will appear tough and slow to retract. Sliding and incarcerated hernias can be cecum, sigmoid colon, etc., and need to focus on that area. If an inguinal hernia is present, you need to seek medical attention as soon as possible to avoid further aggravation.
