Signs and symptoms
Common signs and symptoms that may indicate this condition.
Warning signs - seek immediate care
Jaundice
Yellowing of the skin and whites of the eyes due to bilirubin buildup from blocked bile flow.
Seek immediate care if jaundice is accompanied by fever, severe pain, or confusion, as this may indicate a serious infection.
Fever
High temperature often accompanied by chills, indicating possible infection or inflammation.
Seek emergency care immediately if fever is accompanied by jaundice and abdominal pain (Charcot's triad), as this suggests acute cholangitis.
Right Upper Quadrant Pain
(gastrointestinal)Pain or discomfort in the upper right abdomen, often radiating to the back or shoulder blade.
Frequency: 60-70% of patients
Pruritus
(dermatologic)Intense itching, particularly on the palms and soles, caused by bile salt accumulation in the skin.
Frequency: 50-60% of patients
Dark Urine
(gastrointestinal)Urine that appears brown, amber, or tea-colored due to excess bilirubin being excreted by the kidneys.
Frequency: 40-50% of patients
Pale or Clay-Colored Stools
(gastrointestinal)Stools that appear pale, gray, or tan due to lack of bilirubin entering the intestines.
Frequency: 30-40% of patients
Nausea and Vomiting
(gastrointestinal)Feeling sick to the stomach or actually vomiting, often related to bile flow obstruction.
Frequency: 30-40% of patients
Unexplained Weight Loss
(constitutional)Losing weight without trying, often due to malabsorption of fats and decreased appetite.
Frequency: 15-20% of patients
Diagnosis and tests
How this condition is diagnosed and what test results mean.
Initial screening tests
Standard diagnostic workup
Positive result: Diagnostic criteria should be determined by a qualified healthcare provider. [Content pending medical review.]
Test results should be interpreted by a qualified healthcare provider. [Content pending medical review.]
Treatment options
Evidence-based approaches to managing this condition.
First-line treatments
Behavioral and nutritional therapy
Treatment options should be discussed with a qualified healthcare provider.
Endoscopic intervention with stenting
ERCP allows visualization and treatment of extrahepatic bile duct abnormalities including stricture dilation, stent placement, or stone removal. This minimally invasive approach resolves obstruction and restores bile flow.
Additional treatment options
Surgical bile duct repair or reconstruction
When endoscopic approaches are insufficient, surgical intervention can repair or reconstruct damaged bile ducts. Procedures include choledochojejunostomy or hepaticojejunostomy to restore bile drainage.
surgicalBile acid therapy and antibiotic management
Ursodeoxycholic acid may be prescribed to improve bile flow and protect liver cells. Antibiotics address associated infections. These medications support overall bile duct health and prevent complications.
medicationNutritional support and fat restriction
Dietary modifications including fat restriction and medium-chain triglyceride supplementation reduce bile demand. Adequate hydration and avoidance of hepatotoxic substances support liver and bile duct function.
lifestyleImaging and laboratory surveillance
Regular liver function tests, imaging studies including ultrasound or MRCP, and tumor marker monitoring detect complications early. Surveillance schedules are individualized based on underlying condition and risk factors.
monitoringWhen to seek medical help
