Abstract:
Objective To explore the differences in morphology and structure of collagen fiber of the hilar bile duct between human and rat. Methods The morphology and structure of vertical and horizontal cross-section of human and rat collagen fiber of the normal and dilated hilar bile duct, and their changes under stress were observed after Masson trichrome staining. Results The morphology and structure of collagen fiber of hilar bile duet in human was similar to that in rat. The collagen fiber mainly distributed in the middle and outer layer of the hilar bile duct. The wave-like collagen fiber bundles were arranged in parallel, consistent with the longitudinal axis direction of the bile duct, and connected by the small branches. Conclusions The morphology and structure of collagen fiber of the hilar bile duct in human is similar to that in rat. The anatomical structure of the collagen fiber is adapted to its function.
