Outline of Research at the Start

胆道悪性疾患(胆管癌や胆嚢癌)の手術治療において、胆管を切除した後、再び肝臓から腸に胆汁を流すために胆道再建が必要である。胆管の断端を腸(空腸)に吻合する「胆管空腸吻合」が広く行われているが、腸内細菌が直接肝臓に逆流して胆管炎を起こすなど問題は多々ある。我々は、切除した胆管を人工物を用いて間置ことで、切除する前に近い胆汁の流れを再建することで、「胆管空腸吻合」の多くの問題点を克服できると考える。我々はこの人工物を「人工胆管」とし、生体分解性の素材を用いて、管腔構造の医療材料を開発し、細胞や動物を用いた実験にてその効果を検証する。

Outline of Final Research Achievements

We have developed artificial bile ducts (ABDs) using Gelatin Hydrogel Nonwoven Fabric (GHNF) in cooperation with The Japan Wool Textile. CO., LTD. In transplantation experiments of ABDs in rats, we confirmed that the GHNF served as a scaffold to promote cell infiltration and tissue structure construction, after which the GHNF was degraded entirely, and the bile duct structure was regenerated. Based on these findings, transplantation experiments were conducted in pigs. As the strength of the GHNF alone was insufficient to anastomose to the bile ducts of pigs, a polyglycolic acid tube was used as the inner layer, which was wrapped with a GHNF sheet as the outer layer. It was confirmed that the ABD materials were wholly absorbed, and a new bile duct structure was regenerated 105 days after surgery.

Academic Significance and Societal Importance of the Research Achievements

胆管切除や胆管損傷後の胆道再建は、残存胆管と空腸を吻合する「胆管空腸吻合」が標準的な胆道再建法であるが、欠損胆管部を「人工胆管」で間置する方がより簡便、かつ生理的である。人工胆管は求められる機能(胆汁の十二指腸への運搬)が比較的単純である割には未だ開発が成功していない。人工胆管が常時使える製品として医療現場に存在すれば、胆管切除後の再建法に革命的な変化をもたらし、手術時間の短縮、手術合併症の低下、逆行性胆管炎の減少に繋がり、ひいては医療費の削減につながることが期待できる。
