["Oddipathies" (author's transl)].

The modern anatomy has notably increased the knowledge of details, in biliary surgery, mainly about the sphincter of Oddi, thanks to the use of an adequate radio diagnosis set in the operating room. The term of Odditis is too widely used. It must be replaced by Oddipathies, each disease being defined by its nature and its precise location. Medical and surgical therapy will be adapted to this millimetric scale.
