Endoscopic Scissors Cutting Nasobiliary Duct VS Bilateral Plastic Stent

Overview

The purpose of this study is to explore the efficacy and safety of endoscopic scissors cutting nasobiliary ducts in the treatment of malignant hilar biliary tract stenosis

The early diagnosis of hilar bile duct stenosis is difficult, and when the patient is diagnosed, the opportunity for surgical radical resection is lost, resulting in a poor prognosis. Effective palliative treatment can significantly improve their quality of life and survival time. The method of cutting nasobiliary ducts with endoscopic scissors has many advantages. Firstly, there are multiple lateral foramen of the nasobiliary duct, which increases the drainage area. Secondly, the nasobiliary duct can be retained in the secondary bile duct, which is difficult to achieve with a conventional stent. The use of nasobiliary ducts can also reduce the difficulty of converting from external drainage to internal drainage.
