このプロトコルは ALPPS の動物モデルの PVL + T、約 2 倍の PVL 単独と比較して 3 日以内のボリュームの増加による、急激な肥大を呈する。17で図 1に示すように、中間の肝はその左側と右側に 2 つの独立したポータルの静脈によって提供される 1 つの連続した実質の質量ので右中肝、肝成長モデル葉として使用は最近、公開された作品。17</sup...

肝臓の残りのサイズは、肝腫瘍の切除を制限します。1一般的なとき未満 25% 肝組織の背後に残っている、患者 (「小さすぎるサイズ症候群」) 全体の有機体の代謝機能の不足のため急性肝不全から死リスク増加になります。2このポスト肝肝不全は、肝切除後最も壊滅的な合併症。そのため臨床医は門脈の流れを操作することによって肝切除術前に肝再生を誘導するために試してみました。3門脈を閉塞すると、一度門脈血流の残りの部分は遅い速度で成長を開始し、それにより 60% までサイズを増やすことができますがわかった。4外科的結紮5またはインターベンショナル門脈閉塞が両方とも臨床的に確立されています。4ボリュームや肝臓の機能の増加、信頼性ですが肝部分切除後の残肝の成長に比べて肝臓ポータル閉塞がのみ約 5 分の 1 した後の成長率。6
成長する肝臓に必要な時間は数ヶ月に数週間肝臓を切除後、はるかに速い速度で再生成できます。このように、肝臓はそれの部分を除去した後正常に戻る育つ唯一の器官です。7同じようなペースで肝再生を誘導する部分的な hepactectomy が開発された後外科医のグループによって人は、閉塞間の離断を追加することを発見したし、非閉塞部肝臓肝臓を誘導する新規プロシージャ肝切除後、切除前と同じ成長速度で肥大します。9手順開始一週間以内の大規模な主に切除、肝腫瘍の切除を可能にする、将来的に肝週残内 80% の急速な肥大します。プロシージャを呼び出した「段階的肝切除ための関連付け肝臓パーティションおよび門脈結紮 = ALPPS」、世界中で急速に人気となった。10複数のレポートは、11複雑な手術もその高い合併症率批判された一方、新技術により境界線切除可能肝腫瘍の手術適応の拡大をサポートしました。12,13
2012 年より組織学的特性とメカニズムの理解を許可して薬の効果をテストする ALPPS の出版物以来、齧歯動物の開発、またゆっくりと急激な肥大の大動物モデルが試みられました、動物肝組織の異なる成長率。開発最初の動物モデルは、ラットのモデルだった。このモデルでは、右と中央の葉の左の部分の間の実質の断裂後の急激な肥大は右中央の葉の再生を加速しました。14別のモデルはマウスに後で導入されました。このモデルでは左葉外側切除し、肝左の中央葉以外のすべての葉の門脈枝が結ばれました。15一方で、豚の ALPPS の大動物モデル記載されているも.16
流量の変化と門脈血流、肝組織の酸素圧力のような生理学的メカニズムの研究、ラット モデルはマウスにおける ALPPS のモデルより優れています。マウスのモデルをラットのもう一つの利点は、ラットのモデルは左葉外側と ALPPS の肝切除術の効果を汚染することがあります15の切除の必要がないことです。ラットのモデルは対照的に肝臓を減らさない細胞塊。豚モデル成長葉として右後葉を使用しますが、豚肝臓、高い葉状。したがって、右後部と右前頭葉の間既に薄い組織橋で切除平面を作成することは困難です。対照的に、個別に各ポータル静脈によって提供される 2 つの部分から成っているラットの中葉と顕微鏡技術を使って 2 つの実質の断裂面を簡単に作成することができます。小さな動物のコンピューター断層撮影 (CT) および/または磁石共鳴画像 (MRI) の空室状況により追加切除と門脈結紮門脈結紮だけで体積の成長の非常に正確な定量化が重要であります。任意の急速な肝肥大モデルの検証。
ここに示すプロトコルを記述する手技と体積の検証および門脈結紮とを離断、門脈結紮後ゆっくりと急激な肥大のモデルの生理学的特性に使用するプロシージャそれぞれ、ラット。

最近の臨床データは、プライマリおよび転移性の肝腫瘍に積極的な外科的アプローチをサポートします。大腸癌肝転移のようないくつかの兆候の大きな切除または多発性肝腫瘍の主な制限要因となっている肝切除後肝組織の量が後ろに残って。ポスト肝切除術の重篤な合併症を避けるために必要な機能組織の最小限な肝不全、高い罹患率と死亡率を持っています。肝切除の前に将来の残成長を誘導するより定着して肝臓手術、インターベンション放射線科医によって門脈塞栓術の形でまたは門脈結紮切除術の前に数週間の形で。最近、肝再生より広範かつ急速に、最初の段階ではし、1 週間だけ待っている、第 2 ステージ (肝臓パーティションを関連付けることで切除後の門脈結紮に実質の断裂が追加されることが示されました。段階的肝切除のため門脈結紮 = ALPPS)。ALPPS は急速に人気となって、世界中が、その高周術期死亡率を批判されています。この手順による迅速かつ広範な成長のメカニズムはよくわからなかった。動物モデルは、ALPPS 加速肝再生の生理学的および分子メカニズムを探索する開発されています。このプロトコルは、加速再生の機構の探査ができるラット モデルを示します。

2 つの異なる手術門脈結紮 (PVL) と明らかに異なる成長カイネティクスの断裂 (PVL + T) 結果に PVL。PVL PVL + T ではるかに大きい中央右葉 (RML) ができるに対し、3 日以内の適度なボリュームの増加を誘導する (図 5) を見た。これは、毎日の超高速で検証できます。それは PVL + t.17でトリプル中に PVL で 3 日以内、RML の量が約 2 倍しま?...
