简要总结
Biliary drainage is the mainstay of the palliative treatment in patients with inoperable malignant bile duct stricture. Endoscopic retrograde cholangiopancreatography (ERCP) is the cornerstone of biliary drainage method in these patients. However, ERCP is sometime unsuccessful to perform because of the presence of the high grade biliary stricture, tumor invasion of duodenum and ampulla of vater and surgically altered gastrointestinal anatomy. Endoscopic ultrasound (EUS) guided biliary drainage has been emerged as an alternative procedure to traditional surgical bypass and percutaneous trans hepatic biliary drainage after failed ERCP. There were few data to directly compare between ERCP and EUS guided biliary drainage and in patients with malignant high grade biliary stricture.
详细描述
The aim of this study is comparing the efficacy and complications between ERCP and EUS guided biliary drainage in patients with malignant high grade biliary stricture. Malignant high grade biliary stricture has not been well defined. The investigators define this malignant high grade biliary stricture using these arbitrary number include total bilirubin ≥ 15 mg/dl and or bile duct diameter ≥12 mm. based on the investigation's experience.
The study will be divided patients with inoperable malignant high grade biliary stricture into 2 groups, group (A) will be undergone ERCP with biliary stenting and group (B) will be undergone EUS guided biliary drainage. If the assigned intervention is not successful, then patients will be crossed-over to the another intervention.
