On the history of the opening of the ileocecal valve Kaspar Baugin

Abstract

The ileocecal valve, or “Bauginian valve,” is named after the Swiss scientist Caspar Baugin (1560-1624), who discovered it in 1579. The objective of
he study was to reconstruct the chronology of Baugin’s discovery of the ileocecal valve and its circumstances. The following works by Caspar Baugin were studied: appendices to the Latin translation of Francois Rousset’s work “L'hysterotomotokie ou enfantement cesarien” (1586), “De corporis humani partibus externis” (1588), “De corporis humani fabrica libri HU” (1590), “ Anatomica corporis virilis et muliebris historia"
(1597), "Theatrum anatomicum" (first edition 1605, second edition 1621). The authors note that Baugin discovered the ileocecal valve in 1579, when
e was studying at the University of Paris, during one of Thomas Koch’s private anatomy lessons (washing the intestines, for which he poured water
nto it either through the jejunum or through the rectum ). For the first time, Baugin described in detail its structure, purpose, as well as the circumstances of its discovery in 1586 in the appendix to his published Latin translation of the work of the French physician Francois Rousset (1535-1590) “L'hysterotomotokie ou enfantement cesarien.” As follows from the second edition of Baugin’s work “Theatrum anatomicum” (1621), the
xistence of the valve was known to the Italian anatomist Costanzo Varolio (1543-1575) before him. However, his observations were published after is death in a work entitled
