The circular and longitudinal muscle fibers encircling the terminus of the bile and pancreatic ducts carry the name of Ruggero Oddi, an Italian anatomist and physiologist who identified their specific physiological properties in 1887. This anatomical feature, now globally recognized as the sphincter of Oddi, solidified his place in the historical record of gastroenterology.
Academic Training and Early Research
Born in 1864 in Perugia, Oddi pursued medical studies across several Italian institutions, specifically the University of Perugia, the University of Florence, and the University of Bologna. At the age of 23, while still a student, he conducted the observations that led to his primary contribution. Although the English physician Francis Glisson had initially noted the presence of these fibers two centuries prior, Oddi was the first to successfully characterize their functional role within the digestive system.

In 1894, Oddi received an appointment as head of the Physiology Institute at the University of Genoa. His tenure there was marked by his scientific work, yet his career faced an abrupt conclusion. By 1900, institutional authorities relieved him of his academic position citing professional misconduct involving fiscal improprieties and the personal use of narcotics.
Later Career and Death
Following the termination of his appointment at the University of Genoa, Oddi sought new professional opportunities abroad. He eventually relocated to work as a doctor within the Belgian colonial medical service and spent a portion of his subsequent career in the Belgian Congo. He died in Tunis, Tunisia, on March 22, 1913.

Questions readers ask
Was Ruggero Oddi the first person to discover the sphincter that bears his name?
No. The English physician Francis Glisson identified the sphincter two centuries before Oddi, but Oddi was the first to accurately characterize its physiological properties.
What is odditis?
It is a medical term used to describe inflammation of the junction between the duodenum and the common bile duct at the site of the sphincter of Oddi.
