Description
1)内視鏡観察下に腫瘍などの粘膜病変(5)を確認し、病変部位の周囲に切開予定線を想定し高周波電流(10)などを用いてマーク(7)する(図1)。
2)次に、病変部位の中心(病理学的治癒診断に影響与えず、かつ中心に近い部位)から23G(ゲージ)程度の市販されている内視鏡用穿刺注入針(6a)を用いて生理食塩水3ミリリットル程度(8)を粘膜下に注入して、製剤(9)を確実に注入できるスペースが作られたことを粘膜が挙上したことにより確認する(図2)。
3)引続き同じ穿刺部に、18G(ゲージ)もしくはこれより太い内視鏡用穿刺注入針(6b)を用いて本発明の製剤(9)を粘膜下に注入し、病変部位(5)を含めた前述のマーキング部周囲まで隆起させる(図3)。
4)病変部位(5)の全周にわたって前述のマーキング(7)に沿って高周波ナイフ(10)を用いて切開(11)する(図4−5)。
5)把持鉗子(12)により、病変(5)をつかみあげて(図6)剥離を確認する(図7)。
本発明の製剤を粘膜下に注入した時点で剥離されているので、上記工程により病変の剥離完了である。もし、一部不十分な剥離部がある場合には、その部分をスネアーや高周波ナイフ(10)により切除する。
さらに、本発明の要旨を逸脱しない範囲で種々変形実施できることは勿論である。

Claims (1)
- 内視鏡的粘膜下層剥離術又は内視鏡的粘膜切除術において粘膜下層に注入する溶液からなる内視鏡用局注剤であって、
前記溶液は、カルボキシメチルセルロースナトリウムの溶液で、且つ、針径21ゲージの内視鏡用穿刺注入針では粘膜下層に注入することができず、針径18ゲージもしくはこれより太い内視鏡用穿刺注入針により粘膜下層に注入することが可能な濃度に調製され、且つカルボキシメチルセルロースナトリウムの濃度が1.5〜3.5W/V%であることを特徴とする内視鏡用局注剤。
