◆要旨:【目的】当科のロボット支援下直腸癌手術の短期成績を明らかにすること.【対象および方法】2011年12月~2012年7月に,原発性直腸癌23例に対しロボット支援下手術を行った.そのうち,total mesorectal excision(TME)またはtumor-specific mesorectal excision(TSME)を施行した14例を対象に,その安全性と術後早期経過を解析した.【結果】患者の平均年齢は67.5歳.男性7例,女性7例であった.術式は高位前方切除術1例,低位前方切除術10例,ISR3例であった.手術時間中央値は322分(156~415分),コンソール操作時間中央値は222分(86~302分)であった.開腹手術への移行例はなく,縫合不全などの合併症もなかった.全例根治度Aの手術が施行されていた.【結論】ロボット支援下直腸癌手術は,安全性と術後早期経過において良好であった.
[Aim]The aim of this study was to evaluate the short term outcome of robotic-assisted surgery for rectal cancer. [Method]Fourteen patients undergoing robotic-assisted total mesorectal excision or tumor-specific mesorectal excision for rectal cancer between December 2011 and July 2012 were investigated in this study. [Result] One patient had high anterior resection, 10 patients had low anterior resection, and 3 patients had intersphincteric resection. The median operation time was 322 (156-415) minutes, and console time was 222 (86-302) minutes. Conversion rate was 0% and complication rate was 0% respectively. The circumferential margin and distal resection margin were negative for all patients. [Conclusion] Robotic-assisted surgery for rectal cancer was safe and effective.
