Heel tap sign

Heel tap sign is a clinical sign used in the medical field, particularly in gastroenterology. It is used to diagnose ascites, a condition characterized by the accumulation of fluid in the peritoneal cavity. The sign is named after the action performed during the examination, which involves tapping the patient's heel.

Procedure

The heel tap sign is performed with the patient lying down. The examiner taps the patient's heel. If the patient experiences pain or discomfort, the heel tap sign is considered positive. This could indicate the presence of ascites or peritonitis, an inflammation of the peritoneum.

Clinical significance

The heel tap sign is a valuable tool in the diagnosis of ascites. Ascites is often caused by liver diseases such as cirrhosis and hepatitis, but can also be a symptom of heart failure, kidney failure, or cancer. A positive heel tap sign can help guide further diagnostic procedures and treatment plans.

Limitations

While the heel tap sign can be a useful diagnostic tool, it is not definitive. Other tests, such as ultrasound or CT scan, are often needed to confirm the diagnosis. Furthermore, the sign may not be positive in all patients with ascites, particularly those with minimal fluid accumulation.
