November 2024

Laboratory of Cancer Treatment and Tissue Regeneration, Biomedical Center, Faculty of Medicine in Pilsen, Charles University in Prague, Pilsen, Czech Republic.

Reconstruction of extrahepatic bile ducts is a staple procedure of HPB surgery. The current standard for most cases is a nonanatomical bilioenteric reconstruction, a satisfactory option for the majority of patients. However, it cannot be used for a small number of selective cases (short bowel syndrome, severe abdominal adhesions), where an anatomical reconstruction with or without an interponate can be used.
