◆要旨:わが国において生体腎移植における腹腔鏡下ドナー腎摘出術は,低侵襲であること,美容的に優れること,早期に退院し社会復帰が可能なこと,などの利点があることから広く普及しつつある.種々の腹腔鏡下ドナー腎摘出術の中で,本稿では用手補助後腹膜腔鏡下ドナー腎摘出術について述べる.この術式の利点は,手術時間が短いこと,腎動静脈がより長く採取できること,予期せぬ出血にも容易に対応可能なことなどである.また,用手補助でない術式と比較して温阻血時間を短縮できる.筆者らは狭い後腹膜腔での操作腔を広くするために,ハンドポートは下腹部に置いている.用手補助後腹膜腔鏡下ドナー腎摘出術は現在では安全で容易な手術手技となっている.
Laparoscopic live donor nephrectomy has been widely accepted in Japan, because it has some advantages such as less invasiveness, better cosmetic results, and shorter hospital stay with an earlier return to normal activity. Among several procedures of laparoscopic donor nephrectomy, hand-assisted retroperitoneoscopic donor nephrectomy is described in this article. The main advantages of this procedure are shorter operation time, longer length of renal allograft vessels, and easy control of sudden intraoperative hemorrhage. It also minimizes warm ischemic time compared with pure laparoscopic donor nephrectomy. To maximize the retroperitoneal working space in this procedure, hand-port is located in lower abdomen. Hand-assisted retroperitoneoscopic donor nephrectomy has become a safe and easy procedure and is now a standard policy in our hospital.
