Estimation of Vascularization After Treatment of Deep Rectovaginal Endometriosis Node by Rectal Shaving

Indocyanine green is a dye, using in surgery to bring out the intraoperative evaluation of tissue perfusion. After intravenous injection of indocyanine green, using a near infrared light, the vascularisation becomes fluorescent. In endometriosis disease, the treatment of recto vaginal node can be complicated by rectovaginal fistula. An abnormal vascularisation related to the surgery would be a risk factor of post operative fistulas. The aim of this study is to evaluate the rectal and vaginal vascularisation during the treatment of a recto vaginal endometriosis nodule with rectal shaving, using indocyanine green fluorescence.
