近年来宫颈癌的发病呈年轻化趋势,许多宫颈癌患者在接受了广泛子宫切除、盆腔淋巴结清扫术后面临放疗前保留卵巢功能的问题。由于卵巢对放射线极为敏感,盆腔放疗会使保留于盆腔原位的卵巢功能丧失,因此对于需接受盆腔放疗的患者为保留女性内分泌功能需要将卵巢移位于盆腔放疗野以外的区域,称为卵巢移位术。目前常用的术式是卵巢结肠旁沟移位术(lateral ovarian transpositionLOT),即术中游离卵巢动静脉15cm～20cm,将卵巢固定于同侧结肠旁沟的腹膜上,以期最大限度避免术后放疗对卵巢造成不可逆的损害,保留卵巢功能,
In recent years, the incidence of cervical cancer is younger trend, many patients with cervical cancer after receiving a wide range of hysterectomy, pelvic lymph node dissection is faced with the issue of preserving ovarian function before radiotherapy. Because the ovary is extremely sensitive to radiation, pelvic radiotherapy will remain in the pelvic cavity in situ ovarian function loss, so for patients who need pelvic radiotherapy to retain the female endocrine function need to ovarian transposition in the pelvic radiotherapy field outside the area, known as the ovary Shift surgery. At present, the commonly used surgical technique is lateral ovarian transposition (LOCOTLOT), that is, free ovarian artery and vein intraoperative 15cm ~ 20cm, the ovary is fixed in the peritoneum of the ipsilateral colonic gorge in order to maximize the avoidance of postoperative radiotherapy Cause irreversible damage to the ovary, retain ovarian function,
