Sphincter of Oddi Dysfunction Treatment

When a patient is diagnosed with sphincter of oddi disorder, only then can an endoscopic sphincterotomy be performed that will open the valve and immediately provide relief for the pressure that is causing the array of issues. There are really no other treatment options available to the patient at this point in time, especially if medication has already been tried.

There are 2 types of sphincterotomy :

  1. Lateral Internal Sphincterotomy (LIS) – This the only type of sphincterotomy used to treat anal fissure.
  2. Endoscopic Sphincterotomy (EST) – This is a type of surgery using endoscope to remove gallstones from bile (not a treatment for anal fissure)

Endoscopic sphincterotomy is the current standard of therapy for sphincter of Oddi dysfunction. Controlled studies document the short-term and long-term efficacy of endoscopic sphincterotomy with relatively low morbidity and mortality rates. The presence of an elevated basal sphincter pressure appears to predict good benefit from sphincter ablating procedures. In appropriate situations, benefits of endoscopic sphincterotomy are greater than 90%, with good results in long-term follow-up.
