Function Regulation Assessment and Pathophysiological Dysfunction Repair of Oddi Sphincter.

Area of Science:

• Gastroenterology and Hepatology
• Surgical Innovation
• Diagnostic Imaging

Background:

• The sphincter of Oddi (SO) is a crucial valve in the pancreatobiliary system.
• Its functional assessment and repair remain areas needing further investigation.
• SO dysfunction is linked to pancreatobiliary diseases and increased cancer risk.

Purpose of the Study:

• To systematically review SO regulatory mechanisms, diagnostic methods for dysfunction, and repair strategies.
• To highlight the need for advanced assessment tools in precision medicine.
• To explore the link between SO anomalies and biliary tract carcinogenesis.

Main Methods:

• Systematic review of existing literature on SO function, dysfunction, and treatment.
• Analysis of regulatory mechanisms (neural, humoral, neurohumoral).
• Evaluation of diagnostic techniques including invasive SO manometry (SOM) and noninvasive methods like QHBS and ss-MRCP.

Main Results:

• SO myoelectrical activity is complex and incompletely understood.
• Abnormal SO motility is associated with pancreatobiliary diseases.
• Noninvasive diagnostic tools show clinical promise, complementing invasive SOM.
• Various endoscopic and surgical repair strategies exist for SOD.

Conclusions:

• Standardized noninvasive assessment tools are essential for precise diagnosis of SO disorders.
• Developing quantifiable and visualizable methodologies will improve understanding and patient outcomes.
• Further research is needed to fully elucidate SO regulatory pathways and optimize treatment strategies.
