Medical Eponyms
Ramstedt Operation (pylorotomy) (1912)

Longitudinal myotomy of the pyloric muscle without attempt to close the defect, in contrast to previous methods involving closure of the hypertrophied muscle

Ramstedt is credited with pioneering the modern surgical management of Pyloric Stenosis

While working in Munster, Ramstedt suggested that simple pyloric myotomy may surfice for management of Pyloric Stenosis (1911) rather than attempting closure of the pyloric muscle, as was carried out previously. He carried out and described this procedure in the October 1912

His description of this method was preceded by Sir Harold Stiles in Edinburgh, who performed and documented the operation in February 1912

Major Publications


Ramstedt’s name was spelt with two ‘m’s (Rammstedt) in publications pre ~1920, due to an error apparently introduced by his grandfather into church records. He appears to have reverted to the original spelling after discovering this following WWI.
