目的:成人鼻涙管閉塞に対して2種類の管(stent)を留置し,その表面形状を比較すること。対象と方法:50歳代の女性6例に涙道チューブ留置術を行った。3例にはヘパリンで表面処理をしたポリウレタン管,他の3例にはシリコーン管を使用した。1か月後に抜去し,その表面形状を走査電子顕微鏡で検索した。結果:全6例で流涙と眼脂が改善し,2群間で臨床所見に差がなかった。走査電子顕微鏡では,ヘパリンで表面処理をしたポリウレタン管のほうが表面が平滑であった。結論:ヘパリンで表面処理をしたポリウレタン管のほうがバイオフィルムの付着が少なく,留置後の症状改善や肉芽形成が少ないなどの可能性がある。
Purpose:To evaluate the surface property of two types of tubes used for nasolacrimal duct obstruction in adults. Material and methods:Six female patients in the sixth decade were treated by retention of tubes for nasolacrimal duct obstruction. Three patients received a heparin-coated polyurethane tube. The other three received a silicone tube. The tubes were removed one month later and were examined by a scanning electron microscope(SEM). Results:All the six cases showed improvement in lacrimation and eye discharge after treatment. There was no difference in the effect between the two groups. When examined by SEM,heparin-coated polyurethane tube showed a smoother surface. Conclusion:Heparin-coated polyurethane tube is expected to show lesser biofilm formation resulting in better clinical effect and lesser granulation after prolonged retention.
