Eligibility Criteria
You may qualify if:
- Consecutive untreated patients with biliary obstruction (Bismuth type II, III) at the hilum due to primary cholangiocarcinoma, gallbladder cancer, or periportal lymph node metastases. Diagnosis is based on US, CT, and MRCP.
- Histologic or cytologic confirmation of malignancy is established by percutaneous biopsy (US- or CT-guided) or by endoscopic tissue sampling, endoscopic brushing. Or the diagnosis is based on typical features on imaging and the expected clinical outcome during follow-up.
- All patients were considered unsuitable for resection on the basis of general medical condition and/or tumor extent.
- Full and informed consent is obtained.
You may not qualify if:
- Refuse to participate in this study.
