Dührs•sen, Alfred (1862-1933), German obstetrician-gynecologist. Dührssen is regarded as one of the founders of modern surgical gynecology. In 1893 he developed a technique for facilitating labor by making incisions in the cervix. These incisions are now known as Dührssen's incisions. In 1895 he introduced a new variation of the cesarean section in which the surgery was performed via the vaginal canal. A full description of the operation was published in 1898. He also did research on abdominal cancer.
