Sphincter of Oddi dysfunction (SOD) obstructs bile or pancreatic flow, causing pain or pancreatitis. While manometry is the gold standard, sphincterotomy effectively treats symptoms in type II biliary SOD.

Area of Science:

Gastroenterology
Hepatology
Pancreatology

Background:

Sphincter of Oddi dysfunction (SOD) is a benign obstruction affecting bile or pancreatic drainage.
It presents as biliary pain or idiopathic pancreatitis, categorized into types I, II, and III.
Current noninvasive diagnostic tests lack sufficient sensitivity and specificity.

Purpose of the Study:

To review the diagnostic challenges and treatment efficacy for Sphincter of Oddi dysfunction.
To highlight the role of manometry and sphincterotomy in managing SOD.

Main Methods:

Review of diagnostic modalities for SOD.
Evaluation of treatment outcomes for SOD, focusing on sphincterotomy.

Main Results:

Sphincter of Oddi manometry is considered the gold standard for diagnosis, despite ongoing debates on its accuracy.
Sphincterotomy is the primary treatment, demonstrating effectiveness in symptom palliation for type II biliary SOD.

Conclusions:

Accurate diagnosis of SOD remains challenging due to limitations in noninvasive testing.
Sphincterotomy offers a viable treatment option for symptomatic relief in specific SOD subtypes.
