Summary
Direct manometry of the sphincter of Oddi (SO) reveals its role in bile flow regulation. Abnormal SO manometry patterns in patients with unexplained biliary pain suggest endoscopic sphincterotomy may offer relief.
Area of Science:
- Gastroenterology
- Physiology
- Endoscopy
Background:
- Advancements in endoscopic and manometric techniques enable direct measurement of the human sphincter of Oddi (SO).
- This review synthesizes current knowledge on the SO's physiology and clinical relevance, highlighting Danish gastroenterological contributions.
Purpose of the Study:
- To present the current understanding of the sphincter of Oddi's physiology.
- To review clinical knowledge and diagnostic patterns of the sphincter of Oddi.
- To emphasize the role of Danish gastroenterology in sphincter of Oddi research.
Main Methods:
- Review of existing literature and clinical data.
- Analysis of manometric findings in sphincter of Oddi studies.
- Correlation of manometric patterns with clinical presentations.
Main Results:
- The sphincter of Oddi exhibits elevated basal pressure and phasic contractions, regulating bile flow.
- Neurohormonal factors and slow waves control sphincter of Oddi motility.
- Abnormal manometric patterns are observed in patients with biliary or pancreatic pain lacking organic causes.
Conclusions:
- The sphincter of Oddi plays a crucial role in biliary physiology.
- Abnormal sphincter of Oddi manometry is linked to functional biliary pain.
- Endoscopic sphincterotomy may be a beneficial treatment for select patients with sphincter of Oddi dysfunction.
