Blumberg sign

The Blumberg sign is a clinical sign of local inflammation of the peritoneum ( peritonitis ) that is one of the appendicitis signs. After slowly pressing the abdominal wall in the left lower abdomen by hand, a sharp pain is triggered in the region affected by the inflammation, in the right lower abdomen where the appendix is located, when the pressure is abruptly released . If the peritonitis is advanced, the pain can also be felt when the pressure suddenly decreases in the left lower abdomen on the right; the phenomenon is known as crossed or contralateral pain of letting go .

The triggering of the Blumberg sign is not very specific for appendicitis, just as the fact that it cannot be triggered does not exclude it. The sign can therefore only be used in the context of other clinical findings.

The Blumberg symbol is named after Jacob Moritz Blumberg (1873–1955), a German-Jewish surgeon.
