Key Medical Contributions

Courvoisier’s Law (1890)

Courvoisier’s sign refers to the clinical observation that a painless, palpable, enlarged gallbladder in the presence of jaundice is more likely caused by malignant obstruction (e.g., carcinoma of the head of pancreas or bile duct) than by gallstones.

1899 – Kehr in Anleitung zur Erlernung der Diagnostik der einzelnen Formen der Gallensteinkrankheit confirms the same clinical pattern:

To the results of palpation. In obstruction of the choledochus by a stone the gall-bladder is usually small and not to be felt ; in obstruction by tumor, usually to be felt as a large and elastic distended tumor under the right ribs.
