Outline of Research at the Start

ミニブタの食道および胃に作製したESD 後の粘膜下層剥離面を疎水化ゼラチン多孔膜さらにはHGF 含浸ゼラチン多孔膜で被覆し、その接着性を評価するとともに粘膜下層剥離部における再生・修復促進作用を明らかにすることである。rh-HGF 含浸ゼラチン多孔膜による治療法が確立されれば、内視鏡治療後の瘢痕収縮に伴う狭窄予防にのみならず、炎症性腸疾患などの傷害粘膜の再生・修復を目指した新たな治療法となることが期待される。

Outline of Final Research Achievements

Although endoscopic submucosal dissection (ESD) has become widely used, complications are still an important issue to be resolved. We investigated the usefulness of a highly adhesive gelatin spray formulation using an animal model of post-ESD ulcers. We found that a highly adhesive gelatin spray coating inhibited inflammation and fibrosis of the submucosa and fibrous thickening of the intrinsic muscularis propria of gastric post-ESD ulcers. Furthermore, spraying the spray formulation on post-ESD ulcers in a duodenal ESD ulcer microperforation model using miniature pigs suppressed inflammation in the muscular layer and on the serosa side. The results suggest that this formulation may reduce post-ESD complications.

Academic Significance and Societal Importance of the Research Achievements

今回の研究にて高接着性ゼラチン噴霧製剤が、ESD後潰瘍に対して抗炎症に作用し、微小穿孔の被覆、過度な瘢痕収縮の抑制を通じて消化管狭窄をはじめとするESD後の偶発症予防に有用である可能性が示唆された。本製剤が、臨床日常診療で使用可能となれば、ESD関連偶発症の抑制に寄与する可能性がある。さらには、より安全な低侵襲治療の提供に寄与するだけでなく、日帰り手術が可能になることも考えられ、医療経済的にも貢献する可能性が考えられ、社会的意義は高いものと考える。
