Function of peribiliary glands as well as its relationship with ischemic-type biliary lesions / 中华消化外科杂志

Peribiliary glands (PBG) is a kind of microscopic structure around the intra-hepatic bile ducts and extrahepatic bile ducts. PBG not only participates in maintaining the normal physiological function of biliary epithelial tissue, but also plays an important role in its damage and repair process. Biliary tree stem/progenitor cells in PBG are important cell sources of biliary epithelial regeneration and repair. PBG and the surrounding peribiliary vascular plexus are key influencing factors for the occurrence of ischemic-type biliary lesions (ITBL) after liver transplantation. Based on relevant literatures and clinical practice, the authors summarize the function of PBG as well as its relationship with ITBL.
