Features of biliary obstruction
may be poorly developed in cases in which the biopsy is performed in the first few weeks after birth (usually before 4-6 weeks).
Malignant perihilar biliary obstruction
: Magnetic resonance cholangiopancreatographic findings.
ERCP is regarded as the gold standard for imaging the biliary system and combines the advantage of diagnosis of biliary obstruction
with therapeutic intervention, if required.
The results of the present study indicate that real-time PCR using fluorescence hybridization probes with a PNA clamping reaction and melting curve analysis may offer a promising method to accurately identify K-ras gene mutations in patients with biliary obstruction
. The absence of post-PCR manipulation reduces the risk of carryover contamination and false-positive results.
The fundamental objectives of palliative transhepatic biliary drainage are to improve quality of life by relieving jaundice and pruritus, prevent cholangitis, and avert liver failure caused by progressive biliary obstruction
. (7) In this study of 50 patients with symptomatic jaundice due to advanced irresectable malignancy in whom a surgical bypass or endoscopic stenting was not possible, percutaneous biliary transhepatic self-expanding metal stent insertion was technically successful in all cases.
Transabdominal ultrasound can identify whether there is biliary obstruction
, the level of obstruction, and if there is concurrent gallbladder pathology (gallstones, cholecystitis, etc).
MRCP is a non-invasive and safe alternative to diagnostic ERCP for imaging the biliary tree and investigating biliary obstruction
. MRCP refers to selective fluid-sensitive magnetic resonance imaging (MRI) of the pancreatic and biliary ducts.
In a previous study, we showed that hepatic dysfunction, biliary obstruction
, and pancreatic irritation did not appear to be the mechanisms causing increases of trypsinogen-2 and trypsin-2-AAT in biliary tract disease (20).
The aim of our study is to demonstrate whether multispecies probiotics, which are easily and cheaply available in the market , have an improving effect on bacterial translocation caused by liver and intestinal damage due to biliary obstruction
ERCP is associated with a high risk for biliary obstruction
Clinical success was defined as maintenance of normalized blood chemistry result and no evidence of patients' symptom related to biliary obstruction
until the end of indwelling period of 2 months.
Long term outcomes of patients with significant biliary obstruction
due to portal cavernoma
