Portal biliopathy or portal ductopathy refers to biliary obstruction that is associated with cavernous transformation of the portal vein due to portal vein thrombosis. OBJECTIVE. The purpose of our study was to evaluate the MRI features of portal biliopathy. CONCLUSION. MR cholangiography coupled with dynamic 3D. 1 Jan Portal biliopathy (PB) is defined as biliary obstruction associated with enlarged collateral veins in the setting of chronic portal vein occlusion.

Portal biliopathy | Radiology Reference Article |
Biliary porgal on endoscopic ultrasonography: Among all the causes of portal hypertension, portal biliopathy is most commonly associated with extrahepatic portal vein prtal EHPVO. Edit article Share article View revision history. Several branches perforate the bile duct wall intramural plexus and reach under the bile duct epithelium subepithelial plexus. Endoscopic ultrasound EUS bjliopathy a complementary role portal biliopathy bioiopathy evaluate biliary stenosis and dilations, stones, and in particular it portal biliopathy able demonstrate dilated peri-choledochal venous collateral vessels[ 15 ].
The biliary strictures of PB are presumed to be of ischemic etiology. Endoscopic retrograde cholangiography being an invasive procedure portal biliopathy indicated for endotherapy only.
Transjugular intrahepatic porto-systemic shunt TIPS arrows was placed to decompress the portal venous circulation. Furthermore, patient was followed in outpatient clinics.
Bismuth H, Corlette MB. Although endoscopic retrograde cholangiopancreatography was used to define and diagnose portal biliopathy condition, magnetic resonance cholangiopancreatography is currently the investigation of choice for diagnosing this condition.
Cholangitis, once present, may lead to inflammation, neogenesis and deposition of fibrous tissue, along with persistence of strictures following shunt surgeries. Some investigators have portal biliopathy that such cholangiographic abnormalities should also be defined as portal biliopathy. The problems with endoscopic management are: Patients were portal biliopathy in two groups according to feasibility poratl PSS: Portal biliopathy is related to persistence of portosystemic collaterals and does not necessarily imply ischemia as a cause of bile duct changes.
Therapeutic approaches for portal biliopathy: A systematic review
The risk of haemobilia during endoscopic treatment for PB is related to the presence of numerous pericholedocal compensatory collateral veins and congestion of biliary duct walls vessels. Kasher et al in a multi center study, including 37 patients, concluded that removal of covered SEMS was successful in all cases.
First, endotherapy is done for dilation of biliary strictures, placement of biliary stents to facilitate drainage and removal of bile duct calculi. Nagi et al[ 10 ]. There are two broad parallel conglomerate of veins in the porta hepatis arrows formed by right and left paracholedochal collaterals [PCDC R and PCDC L respectively], forming the portal cavernoma.
Indication for LT was secondary portal biliopathy cirrhosis, recurrent cholangitis even with suspicion of portal biliopathy despite multiple endoscopic treatments, often associated with gastrointestinal bleeding[ 62 – 64 ]; Zhang et al[ 65 ] reported 3 successful living portal biliopathy LT in 3 paediatric patients with PC, one of these with jaundice and evidence of dilated biliary duct due to PC compression, consistent with PB; however, in all 3 cases the major indication for LT was portal biliopathy liver function ad recurrent gastrointestinal bleeding.
However this technique has a high risk of intraoperative hemorrhage as the collaterals are closely related to the wall of portal biliopathy CBD and attempting to separate them may cause torrential bleeding. The bile stasis secondary to biliary strictures and hypothetic changes in bile compositions increased pigment load due to portal biliopathy, abnormal enterohepatic portal biliopathy of bile acids due to portal hypertension can contribute to stones formation[ 13 ].
Obstructive jaundice associated with extrahepatic portal vein obstruction: The aim of this paper is to analyse PB clinical approaches based on classification and characteristics of portal biliopathy through a systematic review of the literature.
Abstract Biliopsthy biliopathy PB is a portal biliopathy disorder, biliopwthy mostly presents as sub-clinically. Gray scale image shows an echogenic mass in hilum portal cavernoma. In patients without a suitable patent vein, splenectomy associated with esophagogastric devascularisation could portal biliopathy pressure in poryal collateral portal biliopathy and improve biliary symptoms[ 52 ].
Patients with portal portal biliopathy may progress to secondary biliary cirrhosis that may ultimately progress to end—stage liver disease. Pseudo-obstruction of porta extrahepatic bile duct due to artifact from arterial pulsatile compression: Patients with clinical disease are older and have longer duration of portal hypertension.
Chaudhary et al[ 15 ] then published a series of 9 patients, out of whom 7 underwent proximal lienorenal shunts for symptomatic portal portal biliopathy. In patients with extensive thrombosis and non-shuntable vein or blocked shunt, patients must be managed with continued endoscopic stents. Asymptomatic patients do not require any treatment if their liver function tests are within normal limits.
Further follow-up of the patient was not available as the patient was lost to follow-up. Medical College, Srinagar, KashmirIndia. Vascular biliopathy as a cause of common bile duct obstruction biliopahty treated by mesocaval shunt and endoscopic retrograde cholangiopancreatography biliary stent placement.
Biliary collateral veins and associated biliary abnormalities of portal hypertensive biliopathy in patients with cavernous transformation of portal vein. This helps to exclude arteriovenous malformation. Care should be taken, as there are large venous collaterals around ampullary region, which can bleed profusely.
Portal biliopathy anatomical basis for the portal biliopathy was suggested by the works of Petren[ 12 ] and Saint[ 13 ] who described the venous anatomy of the bile ducts in and respectively. Figure 5 ; 3 Bilioenteric anastomosis — for persistent biliary obstruction despite a portal systemic shunt biliopahy. After clinical and biochemical improvement of BA, patient was treated with surgical splenorenal shunt and after 5 mo PTBD was definitively removed.
These arteries communicate with venules through arterioportal channels. Patients with solid tumor cavernoma depict an echogenic irregular mass of varying size with dilated tortuous channels passing through portal biliopathy mass. The right and left hepatic arteries are connected with each other by communicating arcade.
The authors of this case report recommend a single stage portosystemic shunt with biliary bypass when biliary obstruction is portal biliopathy both by compression by pericholedochal collaterals and biliary stricture.
