Biliary Tract Dyskinesis Syndrome is also known as Oddi sphincter insufficiency, Oddi sphincter incompetence, Oddi sphincter relaxation, or Vater ampulla incompetence. This syndrome is generally classified into three types: functional, pathological, and mechanical, but it is most commonly associated with cholecystitis, cholelithiasis, and biliary ascariasis.

The patients are mostly elderly women, with right hypochondrium pain as the main symptom; often accompanied by digestive symptoms such as nausea, abdominal distension and fullness, poor appetite, and oil-aversion vomiting. If complications occur, manifestations such as chills, fever, and jaundice may be present.

Barium contrast imaging: The contrast agent enters the intrahepatic bile ducts and the extrahepatic bile ducts. When an oral gallbladder contrast agent reaches the distal end of the common bile duct, it suggests the possibility of hyperkinetic dyskinesia.

bubble_chart Diagnosis

The diagnosis of this disease is often difficult. If the disease is suspected, biliary tract imaging, barium contrast studies, B-ultrasound, and CT scans can be performed to rule out organic biliary tract diseases.

bubble_chart Treatment Measures

The treatment primarily targets the disease cause, symptomatic management, and the treatment of complications. If it is functional, antispasmodic drugs can be used, or Chinese medicinals may also be applied.
