| 目的1/Narrative objectives1 | 下部直腸癌のうち精嚢及び前立腺正中に限局して浸潤する症例に対して、良好な術野確保と操作性の向上のためにTaTMEP或いはTaTMEPを行い、その安全性と腫瘍学的効果及び排尿機能温存効果を検討する。 | We are going to perform transanal (TaTMEP) and transperienal (TpTMEP) total prostatectomy with total mesorectal excision for the lower rectal cancer which invades the only middle part of the seminal vesicles or the prostate to achieve the proper surgical field and further improvement in manipulation. We investigate the safety, the oncological usefulness and the urinary function in TaTMEP and TpTMEP. |

| 選択基準/Key inclusion criteria | 1)下部直腸癌のうち精嚢及び前立腺正中に限局して浸潤する症例を対象とする。
2)試験参加について十分な説明を受けた後、十分な理解の上、患者本人または代承者から自由意思による文書同意が得られた患者。 |
1) The patients with the lower rectal cancer which invades the only middle part of the seminal vesicles or the prostate.
2) The patients who agreed the entry of this study of their own free will in writing by a principal or a substitute after they had comprehended it well by enough explanation. |
|||
| 除外基準/Key exclusion criteria | 1) 広範囲に精嚢・前立腺浸潤症例や骨盤神経浸潤、膀胱浸潤、尿道浸潤症例は除く。
2) 術前CRT(高線量>40Gry)を施行した場合には、吻合部縫合不全のリスクが高まるため、極力膀胱尿道吻合は避けるようにする。 3) TaTMEP或いはTpTMEP施行中(術中)に、良好な術野確保と操作性の向上が見込めないと判断した場合:アプローチ方法を腹腔鏡下或いは開腹に変更するか、術式をTaTPE或いはTpTPEにその時点で移行する。 4) その他、試験責任医師が被験者として不適切と判断した患者。 |
1) The patients with the lower rectal cancer which had widespread invasion of the seminal vesicles, the prostate, the pelvic nerve, the urinary bladder, and the urethra are excluded.
2) The patients who underwent neoadjuvant CRT in particular more than 45 Gry are e excluded because of much risk of leakage of the anastomotic site between the urinary bladder and the urethra. 3) When the proper surgical field or further improvement in manipulation cannot be obtained during TaTMEP or TpTMEP, the approach method should be changed into other approaches such as laparoscopy or open laparotomy, or other surgical methods such as transanal or transperineal total pelvic exenteration. 4) The patients who are inappropriate as the subjects of this study by the corresponding doctor are excluded. |
