Biliary Pain Without Elevated Aminotransferases or Imaging Abnormalities: What to Do for Sphincter of Oddi Dyskinesia
Clinical Scenario
This protocol covers patients with biliary-type pain in whom standard workup is unremarkable: serum aminotransferases are not elevated, the common bile duct is not dilated, and there is no delayed contrast drainage on imaging. This pattern — no significant laboratory or imaging abnormalities — characterises type 3 biliary pain, making the diagnosis of sphincter of Oddi dyskinesia (SOD) particularly challenging to establish and manage.
Treatment Approach
Management is pharmacologic in this setting. Invasive intervention — specifically sphincterotomy — is not indicated for patients presenting this way. The specific agents, their selection criteria, and the full structured regimen are available via the protocol link below.
Clinical goal: Decrease in symptoms and resolution or improvement of biliary-type pain.

- Type 3 Biliary pain.
- Diagnosis of type 3 SOD is challenging due to the lack of significant abnormalities on laboratory testing or diagnostic imaging.
- The study recommended that sphincterotomy should not be performed in patients with biliary type 3 SOD.
- Patients experienced a significant decrease in symptoms and it was therefore concluded that duloxetine could be further studied for the treatment of SOD.
- After treatment with ursofalk for a few months, the biliary-type abdominal pain was significantly improved or resolved, while patients in the control group showed no improvement in symptoms.
