Congenital megacolon observation by Frederick Ruysch—1691

E Leenders, WK Sieber - Journal of pediatric surgery, 1970 - Elsevier
Although the classical description of congenital megacolon is reported by Hirschsprung in
1886, the first recorded instance of this disorder is attributed to F. Ruysch, a Dutch anatomist.
This first case report appears in his work,“Observationum Anatomici-Chirurgicarum
Centuria”, in 1691.
