Overview
Biliary dyskinesia is a failure of proper movement of the sphincter of Oddi.
Failure of the biliary sphincter can be distinguished from the pancreatic sphincter.
Diagnosis
History and Symptoms
In order to exclude other disorders, the patient's history is important in the diagnosis of biliary dyskinesia. Symptoms of biliary dyskinesia are characterized by biliary colic symptoms and include: postprandial pain in the right upper quadrant (RUQ) (that radiate to the flank, back, and right scapula), intolerance to fatty food, pain in the evening or awaking a person at night, bloating, nausea and vomiting.[1]
Physical Examination
Symptoms of biliary dyskinesia are characterized by biliary colic symptoms. The following clinical presentations are not likely due to functional biliary disorder: positive Murphy’s sign, constant abdominal pain without tenderness, jaundice, and intermittent abdominal pain and cramps with episodes of diarrhea or constipation. [1]
Laboratory Findings
The initial laboratory work-up should include: liver function tests (AST, ALT and, total bilirubin), amylase, and lipase.[1]
CT
CT scan is not helpful in gallbladder or biliary diseases.[1]
Ultrasound
Ultrasound is required in these patients in order to exclude structural conditions such as gallstone disease or cancer.[2] Ultrasound may be used in order to diagnose sphincter of oddi disorders (SOD) by measuring the common bile duct (CBD) diameter.[3]
Other Imaging Findings
Hepatobiliary iminodiacetic acid (HIDA) with an abnormal gallbladder ejection fraction (<40%) is a supportive criteria for diagnosing biliary dyskinesia but is not required for the diagnosis anymore.[1][4] Noninvasive procedures that may be used to evaluate and diagnose sphincter of Oddi disorders (SOD) are: ultrasound, HIDA scan, and MRCP.[3]
Other Diagnostic Studies
ERCP and sphincter of Oddi manometry may be used to rule out functional biliary sphincter of Oddi disorder (SOD) in patients who have had a cholecystectomy.[1] Although sphincter of Oddi manometry is the diagnostic tool for evaluating sphincter of Oddi disorders (SOD), it is an invasive procedure and has risk for complications.[2]
Treatment
Medical Therapy
Medical therapy mostly includes of symptomatic treatment of abdominal pain and IV opiates are the drug of choice, although some studies have suggested that opiates cause sphincter of Oddi contraction.[2][5]
Surgery
Laparoscopic cholecystectomy is used to treat biliary dyskinesia. Endoscopic biliary sphincterotomy is performed in patients with sphincter of Oddi disorder (SOD) diagnosed by manometry.[2]
