Hans Kehr

Hans Kehr (1862-1916) was a German surgeon and professor of surgery at Halberstädt, and later Berlin. He is known for the development of operative procedures for the treatment of gall bladder and bile duct diseases.

In the late 19th century, Kehr popularized the cholecystectomy for the treatment of gallstones. Afterwards, the operation became commonplace, with Kehr performing over a thousand cholecystectomies before his death in 1916.

His name is lent to Kehr's sign, which is in an indication of acute pain in the left shoulder associated with a ruptured spleen. He also popularized a device for biliary drainage that today is known as Kehr's T-tube.
