ERCP for SOD 3

Posted , 3 users are following.

I was diagnosed with SOD 3 after having excruciating pains for over 4 years now. I have tried everything but nothing seemed to work. I had botox injection but that relieved the pain a little. Doctors say I should have ERCP,  pls are there any success stories on ERCP for SOD cos I need to make an informed decision.  Thank you

    You may find these pages have information to educate your self. I hope you find what you need to feel better!  Also, I hope you can get some skilled accupuncture to ease the pain.  It has been very helpful for me in controlling pain.

    Functional SOD

    Patients with a similar pain problem, but who have little or no abnormalities on blood tests and standard scans (including MRCP), are categorized as having SOD Type III. The episodes of pain are assumed due to intermittent spasm of the sphincter. It is very difficult to effectively evaluate and manage patients with Type III SOD. Some physicians are skeptical of its existence, or assume that it is a part of a broader problem of a functional digestive disturbance such as irritable bowel syndrome.

    Because of the risks of ERCP, patients with suspected SOD III are usually advised to try medical treatments first. Some respond to the use of antispasmodic drugs and/or antidepressants that may help decrease pain.  There have been studies of other medical therapies, such as calcium channel blocking drugs. Despite a few encouraging reports, these methods have not proven to be effective generally, and are not widely used.

    Patients who fail these approaches (at least those with severe symptoms) are usually advised to see specialists at referral centers. Further evaluation may involve additional or more specialized tests to help guide treatment options.

    Clinical Research Study

    The uncertainties in how best to diagnose and to treat “suspected” sphincter of Oddi dysfunction (and the risks involved) mandate further scientific investigation. The National Institutes of Health has recently funded an important study called “EPISOD” in 6 major Gastroenterology centers in USA.

    The studies are being conducted at centers located in:

    Johns Hopkins Hospital, Baltimore, MD

    University of Alabama at Birmingham, Birmingham, AL

    Medical University of South Carolina Digestive Disease Center, Charleston, SC

    Indiana University, Indianapolis, IN

    Hennepin County Medical Center, Minneapolis, MN

    Virginia Mason Medical Center, Seattle, WA

    Additional details are available at the NIH website at by searching: sphincter of Oddi dysfunction III.
