◆要旨:やや手術難度が高いとされる急性胆囊炎に対する腹腔鏡下胆囊摘出術(LC)において,単孔式腹腔鏡下手術(SILS)用デバイスを応用した手術指導の工夫を報告する.SILSと同様に臍部を2.5cm切開し,同部位より2本のトロッカーを留置する.指導的助手はこのうちの1本を右手用として使用し,止血や圧排とともに術野内での指導を行う.当科でLCを施行した275例を対象に検討を行った.導入以降,技術認定取得前の修練医において,開腹移行,術後合併症を認めず,術後在院期間の有意な短縮を認めた.急性胆囊炎に対するLCはSILS用デバイスを応用した手術指導方法により安全・確実に施行可能であると考えられた.
We reported performing laparoscopic cholecystectomy(LC), which appeared to be a difficult technique to perform in acute cholecystectomy(AC), using single-incision laparoscopic surgery(SILS) device. Regarding the port setting, two trocars(5 mm and 12 mm) were inserted in the navel port using SILS device. The 5-mm trocar at the navel port was used by the instructing surgeon's right hand. Hemostasis was achieved using soft coagulation, appropriate counter traction, and instruction inside the operative field. We analyzed 275 AC patients who performed LC at our department. After introducing this technique, there were no conversion to open surgery, postoperative complications in the surgical trainee group. Early laparoscopic cholecystectomy using SILS device was achievable by a surgical trainee in AC.
