A Review on Portal Biliopathy: Imaging Features of Nine Patients | Chapter 10 | Current Topics in Medicine and Medical Research Vol.5

 

The current chapter has been aimed to discuss the aetiology, pathogenesis, diagnosis and
management of portal biliopathy (PB), supported by a series of 9 cases from a personal series. Most
patients remain asymptomatic, but some may present with raised alkaline phosphatase level,
abdominal pain, fever, and cholangitis. It tends to be associated with gallbladder (GB) wall
abnormalities, a cavernous transformation of the portal vein and choledochal varices. Extrinsic
compression of the common bile duct, (CBD), by dilated venous collaterals together with pericholedochal fibrosis from the inflammatory process can cause portal thrombosis, which may lead to biliary stricture and dilatation of the proximal biliary tree. These strictures do set the scene for the
formation of biliary stones and cholangitis. Imaging features are instrumental in the diagnosis of PB.
This paper presents 9 of such cases of portal biliopathy, with discussions on their causation, the
course of the disease process and management particularly minimally invasive procedure. The role of
ultrasound (US), computed tomography (CT), magnetic resonance imaging (MRI), endoscopic
retrograde cholangiopancreatography (ERCP) and direct puncture cholangiography is discussed.
Surgical management is evaluated. An imaging atlas is provided. PB is an uncommon but significant
complication of portal venous obstruction which does have an insidious onset and may remain
asymptomatic until late. PB has been associated with coagulopathies, and a variety of other
disorders, which are discussed, illustrated and the diagnosis-elaborated. The role of MRI as a noninvasive imaging tool is emphasized.
