Abstract Objective: To explore the application of coaxial catheter technology in severe biliary obstruction caused by pancreatic head cancer, and to provide reference for clinical application. Methods: Twenty cases failed in dredging with common guide wire. But they were successfully dredged with coaxial catheter. The biliary stents were then successfully released at the obstruction plane. Complications and improvement of clinical symptoms associated with hospitalization were observed. The liver function was reviewed in 1 month later after operation and compared with preoperative. Abdominal ultrasound, CT or MRI were performed to know the situation of biliary and stent a month later. Results: All 20 patients were dredged successfully. Chills, fever and pain were present in 2 patients after the operation, and improved after anti-infection and analgesia treatment. Reviewed liver function a month later, and compared with preoperative, the difference was statistically significant(P＜0.05). The related symptoms of jaundice, tired of the oil and skin itching were improved obviously in 20 cases after the operation. A month later, abdominal ultrasound, CT or MRI showed that the intrahepatic and extrahepatic bile ducts without obvious dilatation in 20 cases. The biliary stents were unobstructed and in good position. Conclusion: Coaxial catheter technique can improve the success rate of severe biliary obstruction. It is worth trying and popularizing in clinical work.
