CLASSIFICATION, DIAGNOSIS AND TREATMENT OF BILIARY STRICTURE IN PRIMARY BILE DUCT STONE’S PATIENTS
Main Article Content
Abstract
Biliary stricture is a common disease in East Asia, Southeast Asia, and Vietnam. It significantly affects the results of biliary stone’s treatment, and is a main cause of recurrent stones, causing patients to have to be operated many times. Another way, bile duct stones cause recurrent cholangitis, biliary obstruction or biliary cirrhosis, creating exelent conditions for stricture. It can be said that biliary stricture and stones go hand in hand. It is difficult to determine which is the cause and which is the effect. There are many ways to classify biliary stricture to provide a reasonable diagnosis and treatment plan. To completely evaluate stricture, cholangioscopy combined with X-ray, and next, MRCP and CT-scan are highly valuable methods. Treatment of biliary stones always needs to be accompanied with biliary strictures. Currently, there are many methods to treat biliary strictures in primary bile duct stone’s patients depending on each individual indication. In particular, choledochoscopy, stone lithotripsy, stricture dilation and biliary stent are widely applied minimally invasive methods. They was proved to be effective and safe procedures with hight rate of stone and stricture clearance, low rate of complications and recurrence. However, more studies are needed to evaluate the long-term outcomes.
