Sphincter of Oddi dysfunction and other functional biliary disorders: evaluation and treatment.
Functional biliary disorders encompass the conditions of SOD and gallbladder dysmotility, both of which result in clinical pain syndromes. Obtaining objective diagnostic and outcomes data for both disorders has been an ongoing challenge over the last two decades. SOD, although initially believed to be strictly a biliary disorder, has now been implicated in recurrent pancreatitis. The biliary-type classification allows a clinician to stratify patients who would benefit from SOM and endoscopic sphincterotomy. Further study into the impact of endoscopic therapy for recurrent pancreatitis is needed. By the same token, the dilemma of postcholecystectomy abdominal pain, whether classified as biliary or pancreatic type III, remains challenging. The current limitations of knowledge highlight the need for prospective randomized studies to evaluate the clinical significance of SOM abnormalities to facilitate treatment of these patients.
