Sonographic Murphy Sign

The Sonographic Murphy Sign is a medical diagnostic tool used in the field of radiology and gastroenterology. It is a clinical test used to diagnose acute cholecystitis, an inflammation of the gallbladder.

History

The Sonographic Murphy Sign is named after the American surgeon, John Benjamin Murphy, who first described the clinical sign in the early 20th century. The sonographic version of the test was later developed with the advent of ultrasound technology.

Procedure

The Sonographic Murphy Sign is performed during an abdominal ultrasound. The patient is asked to take a deep breath while the sonographer applies pressure with the ultrasound probe over the area of the gallbladder. If the patient experiences pain or abruptly stops inhaling, it is considered a positive Sonographic Murphy Sign.

Clinical Significance

A positive Sonographic Murphy Sign is highly suggestive of acute cholecystitis. However, it is not definitive and further diagnostic tests may be required. The sign is considered highly sensitive and specific for acute cholecystitis, making it a valuable tool in the diagnostic process.

Limitations

While the Sonographic Murphy Sign is a useful diagnostic tool, it is not without limitations. It may not be positive in patients with chronic cholecystitis or those who have previously had a cholecystectomy. Additionally, it may be difficult to perform in patients who are obese or have a high degree of abdominal pain.
