アクティブコンパレータ:D2 胃切除術
術前の造影腹部CTスキャンは、病変の位置、腫瘍の大きさ、リンパ節転移(LNM)を評価するために実施されます。
術前の内視鏡による色素注入または術中の内視鏡による位置特定は、腫瘍部位を正確に特定し、適切な切除マージンを確保するために利用されます。
リンパ節郭清(LND)の範囲は、日本の胃がん治療ガイドライン2023年(第6版)に準拠しています[4]。
具体的には、D2 遠位胃切除術には、リンパ節 No. 1、3、4sb、4d、5、6、7、8a、9、11p、および 12a が含まれます。
D2 近位胃切除術にはノード 1、2、3a、4sa、4sb、7、8a、9、11p、および 12a が含まれますが、D2 胃全切除術にはノード 1、2、3、4sa、4sb、4d、5、6、7、 8a、9、11p、11d、12a。

準備: 患者は全身麻酔で仰向けになります。
経口胃チューブとフォーリーカテーテルが挿入されます。
抗生物質が投与され、ストッキングが順次装着されます。
ポートの配置: 気腹は臍のベレス針を介して作成されます。
作業ポートは上部四分円に配置され、5 番目のポートは肝臓収縮用です。
腹部の検査:腹部に転移がないか検査され、腹膜細胞診が行われます。
切開とリンパ節の切除: 小網は肝臓の近くで分割され、噴門と横隔膜に達します。
胃結腸靱帯は横行結腸に沿って分割されます。
リンパ節の切除は脾動脈に沿って始まり、次に左胃動脈および腹腔リンパ節に進みます。
左胃血管はエンドクリップで制御されます。リンパ節郭清後、遠位胃亜全摘術が行われます。
消化管の再建は通常、ミニ開腹術によって行われます。

実験的:蛍光誘導腹腔鏡・内視鏡連携センチネルリンパ節ナビゲーション手術層別化
腹腔鏡内視鏡合同手術(LECS)は、内視鏡と腹腔鏡の補完的な長所を統合することで、より標的を絞ったアプローチを提供します。
LECSは正確な標的化、最適な切除マージン、組織温存切除を可能にします。
その結果、LECSは胃の構造と機能をより良く保存し、術後の回復とQOLの向上につながる可能性があります。
それにもかかわらず、SNNSに対するLECSを支持する現在のエビデンスは限られています。

Patients without prior ESD received ESD with laparoscopic sentinel basin dissection (LSBD) for ESD resectable lesions, otherwise patients received laparoscopic-endoscopic cooperative regional gastrectomy (LRG) with LSBD. For patients with prior non-curative ESD, LSBD alone was performed if margins were negative, otherwise LRG with LSBD was conducted. Intraoperative frozen-section pathological examination of the horizontal resection margin of the ESD or full-thickness specimen. During laparoscopic sentinel node basin dissection (LSBD), indocyanine green (ICG) (2 mL, 2.5 mg/mL) was endoscopically injected into the submucosal layer at four quadrants around the marking points (0.5 mL per quadrant). Fifteen minutes after ICG injection, sentinel lymph node basins (SLBs) were defined as the area within a 2 cm margin of the detected fluorescence stained nodes, which were marked with laparoscopic clips. |
