Palliation: Hilar cholangiocarcinoma

Area of Science:

• Gastroenterology and Hepatology
• Oncology

Background:

• Hilar cholangiocarcinomas are frequently unresectable at diagnosis, necessitating palliative care.
• Palliative treatment aims to alleviate symptoms such as jaundice, pruritus, and abdominal pain.

Purpose of the Study:

• To review current palliative strategies for unresectable hilar cholangiocarcinoma.
• To compare the efficacy of different biliary drainage techniques.

Main Methods:

• Review of endoscopic retrograde cholangio-pancreatography (ERCP), percutaneous stenting, and endosonography-guided biliary drainage.
• Discussion of metal versus plastic stents and unilateral versus multiple stenting.
• Consideration of adjuvant therapies like photodynamic therapy and radiofrequency ablation.

Main Results:

• Percutaneous stenting is superior to endoscopic stenting for advanced disease.
• Endosonography-guided drainage is an alternative when ERCP fails or is not feasible.
• Draining over 50% of liver volume and all obstructed segments in cholangitis improves outcomes.

Conclusions:

• Palliative care is crucial for unresectable hilar cholangiocarcinoma.
• Percutaneous and endosonography-guided drainage are effective palliative modalities.
• Optimal stenting strategy depends on disease extent (Bismuth class) and local expertise.
