Preservation of ovarian function is both safe and feasible in many young women with pelvic malignancies. Techniques utilized to transpose the ovaries to date have uniformly required a laparotomy either at the time of surgical treatment or as a separate operation in patients about to undergo pelvic radiotherapy. We report our preliminary results in 3 patients who underwent laparoscopic ovarian transposition and pelvic lymphadenectomy as part of an experimental protocol using intracavitary radiation alone in patients with small node negative stage 1B cervical carcinoma desiring preservation of fertility. Dose calculations were performed to estimate the amount of radiation each transposed ovary received from the intracavitary radiation, as well as the dosage that would have been received had external pelvic (4500 cGy) with or without para-aortic nodal irradiation (4500 cGy) been required. The mean estimated distance each ovary was transposed was 14.4 cm for the right ovary and 14.3 cm for the left ovary. Operative times ranged from 2.75-4.0 hours, and the blood loss 100-300 mls. Post-operative hospital stays ranged from 1-2 days, and no complications were encountered. Two of the 3 patients are menstruating regularly 25-32 months after completion of treatment with serum FSH in the normal premenopausal range. Based on the above distances, the mean dose of radiation each transposed ovary received was estimated to be 126 cGy, whereas the range in dosage of radiation each ovary would have received had external pelvic +/- para-aortic nodal irradiation been required was 135-190 cGy, and 230-310 cGy respectively. One patient has become menopausal after her transposed ovaries slipped back into the pelvis. Laparoscopic ovarian transpositions can be performed. This procedure is technically easy to perform for those surgeons skilled in laparoscopic surgery and its preliminary morbidity appears to be low. More experience, longer followup, and refinement in the methods of ovarian transfixation are required.
对于许多患有盆腔恶性肿瘤的年轻女性而言,保留卵巢功能既安全又可行。迄今为止,用于卵巢移位的技术无一例外地都需要在手术治疗时进行剖腹手术,或者对于即将接受盆腔放疗的患者作为单独的手术进行。我们报告了3例患者的初步结果,这些患者接受了腹腔镜卵巢移位和盆腔淋巴结清扫术,作为一项实验方案的一部分,该方案仅对希望保留生育能力的小淋巴结阴性1B期宫颈癌患者使用腔内放疗。进行剂量计算以估计每个移位卵巢从腔内放疗中接受的辐射量,以及如果需要盆腔外(4500 cGy)加或不加主动脉旁淋巴结照射(4500 cGy)时卵巢本应接受的剂量。每个卵巢移位的平均估计距离,右侧卵巢为14.4厘米,左侧卵巢为14.3厘米。手术时间为2.75 - 4.0小时,失血量为100 - 300毫升。术后住院时间为1 - 2天,未出现并发症。3例患者中有2例在完成治疗后25 - 32个月月经规律,血清促卵泡激素处于正常绝经前范围。根据上述距离,估计每个移位卵巢接受的平均辐射剂量为126 cGy,而如果需要盆腔外±主动脉旁淋巴结照射,每个卵巢本应接受的辐射剂量范围分别为135 - 190 cGy和230 - 310 cGy。1例患者在其移位的卵巢滑回盆腔后已绝经。腹腔镜卵巢移位术是可以进行的。对于熟练掌握腹腔镜手术的外科医生来说,该手术在技术上易于操作,且其初步的发病率似乎较低。还需要更多的经验、更长时间的随访以及改进卵巢固定方法。
