Summary
Brief summary (as posted)
A median survival period of 3 to 6 months is the prognosis for patients with advanced, unresectable EHCC. For patients with locally advanced, unresectable EHCC, effective management of tumor growth is the only option to increase stent patency and survival time. In patients with cholangiocarcinoma, photodynamic therapy (PDT) is therapy that has been shown to improve stent patency and overall survival (OS). Endoscopic radiofrequency ablation (RFA) has been demonstrated in numerous studies to prolong the life spans of individuals with malignant biliary obstruction . In the literature, comparing the clinical efficacy and adverse outcomes of these two endoscopic procedures is rare.

- Photodynamic therapy(PDT)
- description
- The PDT optical fiber was inserted through the dilation catheterand advanced toward the bile duct stenosis point under visual-radiography. The dilation catheter was then withdrawn to leave the PDT optical fiber directly across the stricture. Photoactivation was performed at 640 nm using a diode laser at a light dose of 180 J/cm2at power density of300 mW/cm2 and irradiation time of 600 s.

- Radiofrequency ablation(RFA)
- description
- An RFA electrode (Habib EndoHPB, EMcision, HitchinHerts, UK) was advanced along the guide wire into the bile duct and to the biliary stricture under X-ray fluoroscopic guidance. A 400 kHz RF generator (RITA 1500X, Angio Dynamics, USA) was connected for RFA at 7-10 W for 90 seconds.
