Background: Malignant biliary obstruction is usually attributed to the enlargement of tumors within or adjacent to the biliary tract, leading to blockage or compression of the bile ducts. Common causes include pancreatic head cancer, bile duct cancer, gallbladder cancer, liver cancer, and metastatic diseases. Most cases have an insidious onset, lack effective early screening methods, and 70% of patients cannot undergo surgical resection, with a 5-year survival rate of about 30%. Therefore, relieving biliary tree obstruction is crucial. Biliary stents often mitigate the obstruction but can be hindered by tumor progression, endothelial hyperplasia, and bile sludge. As a result, new treatment approaches are constantly being explored to improve outcomes for patients with malignant biliary obstruction.
Current Situation: One promising technique that has emerged in recent years is radiofrequency ablation (RFA). This innovative method utilizes high-frequency radio waves to generate heat and selectively target tumor cells through localized heating while preserving surrounding healthy tissue. RFA aims to slow tumor growth and enhance biliary stent durability. Studies on endoscopic RFA for malignant biliary obstruction are encouraging. Integrating it with palliative care may better manage symptoms and extend patient quality of life.
Conclusion: In conclusion, while malignant biliary obstruction remains a complex medical challenge with limited treatment options available for some patients, ongoing research into innovative techniques like radiofrequency ablation offers hope for better outcomes in the future. It is crucial for healthcare professionals to stay informed about these advancements and continue exploring new ways to enhance patient care in this difficult clinical scenario.
