Its motility, including phasic contractions and relaxation, is under complex neurohumoral control. Organic or functional obstruction of the OS is an important factor in severe diseases, such as cholangitis and pancreatitis, as well as in functional disorders and recurrent abdominal pain. In this review, we summarize the function of the OS, its disorders, and their diagnostic methods and potential therapeutics. While organic diseases of the papilla often require invasive, mainly endoscopic, treatment, functional disorders should be managed with conservative, individualized treatment, and involve the patient and their family in decision-making.<\/jats:p>","DOI":"10.3390\/jpm16020106","type":"journal-article","created":{"date-parts":[[2026,2,10]],"date-time":"2026-02-10T11:16:38Z","timestamp":1770722198000},"page":"106","update-policy":"https:\/\/doi.org\/10.3390\/mdpi_crossmark_policy","source":"Crossref","is-referenced-by-count":0,"title":["Personalized Treatments for Functional Disorders of the Sphincter of Oddi: A Short Muscle with a Long History of Discussion and Controversies"],"prefix":"10.3390","volume":"16","author":[{"ORCID":"https:\/\/orcid.org\/0000-0001-9449-933X","authenticated-orcid":false,"given":"Zolt\u00e1n","family":"Berger","sequence":"first","affiliation":[{"name":"Departamento Medicina, Hospital Cl\u00ednico Universidad de Chile, Carlos Lorca Tobar 999, Independencia, Santiago 8320000, Chile"},{"name":"Clinica Las Condes, Estoril 450, Las Condes, Santiago 8380456, Chile"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"\u00c1kos","family":"Pap","sequence":"additional","affiliation":[{"name":"Institute of Pancreatic Diseases, Semmelweiss University, T\u00f6m\u00f6 u. 25-29, 1083 Budapest, Hungary"}],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"1968","published-online":{"date-parts":[[2026,2,10]]},"reference":[{"key":"ref_1","first-page":"317","article-title":"D\u2019une disposition a sphincter speciale de l\u2019ouverture du canal choledoque","volume":"8","author":"Oddi","year":"1887","journal-title":"Arch.
