Background And Aims:
Dilated peribiliary glands (PBG) in patients with cirrhosis are often an incidental finding although their significance and physiopathology remain unclear. We aimed to identify clinical factors associated with dilated PBG and to perform a detailed morphometric assessment of dilated PBG in cirrhotic patients undergoing liver transplantation (LT).
Methods:
All consecutive cirrhotic patients undergoing LT at our institution between October 2006 and October 2011 were assessed for inclusion. Ten non-cirrhotic patients were included as controls. We performed morphometrical assessment of PBG, assessed baseline clinical factors associated with dilated PBG, immunohistochemistry staining with CK-19, MiB-1 and EpCAM, and radiological assessment of all available cases.
Results:
Seventy-one patients met the inclusion criteria, 24% had PBG dilatation of >1000 µm. On multivariable analysis, MELD (OR 1.11 per unit increase in MELD, p = 0.004) was the only significant factor associated with dilated PBG. Compared to PBG < 1000 µm, large PBG had a higher proportion of EpCAM-positive (69 vs. 28%, p < 0.001) and MiB-1-positive lining cells (2.8 vs. 0.55%, p = 0.036). Computed tomography and magnetic resonance imaging had high specificity but low sensitivity for the diagnosis of dilated PBG > 1000 µm (specificity 90-100%, sensitivity 25-29%).
Conclusions:
Dilated PBGs are a common finding in explants of cirrhotic subjects undergoing LT and are associated with liver failure although diagnostic performance of cross-sectional imaging is inconstant. The high number of proliferative and EpCAM-positive cells lining the PBG may suggest a role of PBG in organ repair during liver failure.
