In Mayer-Rokitansky-Kuster-Hauser Syndrome (MRKHS) patients who are scheduled for laparoscopic vaginoplasty and have a desire for biological motherhood, we propose that a concomitant laparoscopic oocyte retrieval for cryopreservation is performed. Oocyte retrieval is pursued at the beginning of the laparoscopy. Right and left 5 mm trocars are positioned, through which a 17 G ovum aspiration needle is used for puncture of the right and left ovaries, respectively. To facilitate exposure of the follicles, the ovaries are mobilized and held with laparoscopic forceps. When aspirating multiple follicles near each other, the needle tip is retained in the ovary to reduce the number of times that the ovarian cortex is transfixed and due to the inherent risk of bleeding. Subsequent steps are unchanged compared to the Davydov laparoscopic modified technique for vaginoplasty. Prior to surgery, controlled ovarian stimulation is performed with a gonadotropin hormone-releasing hormone (Gn-RH) antagonist protocol, and the concomitant procedure of oocyte retrieval and vaginoplasty is scheduled 36 h after the final follicular maturation trigger. Follicular fluid is collected in the same 10 mL sterile tubes used during transvaginal oocyte retrieval and transferred in a warming block (37 °C) to the assisted reproduction laboratory, where mature (metaphase II) oocytes are vitrified. In this case, a series of 23 women with MRKH, oocytes were successfully retrieved and cryopreserved in all patients; vaginoplasty was subsequently conducted without modifications, and the inpatient and outpatient postoperative care (day of urinary catheter removal, day of hospital discharge, dilator use, and comfort at follow-up) remained unaffected. One postoperative complication occurred in one patient (fever developing on day 5 post surgery and intraperitoneal fluid detection on transabdominal ultrasound) and resolved after conservative treatment. Rather than performing surgical vaginoplasty and delaying oocyte retrieval in MRKH patients, this approach combines both procedures in a single laparoscopy, thereby minimizing surgical invasiveness and anesthesiologic risks.
在接受腹腔镜阴道成形术且希望生育的 Mayer-Rokitansky-Kuster-Hauser 综合征(MRKHS)患者中,我们建议同时进行腹腔镜取卵以备冷冻保存。取卵在腹腔镜检查开始时进行。在右侧和左侧放置 5 毫米 trocar,通过这些 trocar 分别使用 17 G 卵母细胞抽吸针穿刺右侧和左侧卵巢。为了便于暴露卵泡,用腹腔镜夹移动和固定卵巢。当在彼此靠近的多个卵泡中抽吸时,针尖保留在卵巢中,以减少卵巢皮质被刺穿的次数,并降低由于固有出血风险导致的卵巢皮质被刺穿的次数。与 Davydov 腹腔镜改良阴道成形术相比,后续步骤保持不变。手术前,采用促性腺激素释放激素(Gn-RH)拮抗剂方案进行控制性卵巢刺激,取卵和阴道成形术的同时手术安排在最后一次卵泡成熟触发后 36 小时进行。卵泡液与经阴道取卵时使用的相同 10 mL 无菌管一起收集,并在加热块(37°C)中转移到辅助生殖实验室,在那里成熟(中期 II)卵母细胞被冷冻。在这种情况下,23 例患有 MRKH 的女性成功地取出并冷冻了卵子;随后无需修改即可进行阴道成形术,并且住院和门诊术后护理(导尿管拔除日、出院日、扩张器使用和随访时的舒适度)保持不变。一名患者术后出现了一种并发症(术后第 5 天出现发热,经腹超声检测到腹腔积液),经保守治疗后得到解决。这种方法不是在 MRKH 患者中进行手术阴道成形术并延迟取卵,而是在单次腹腔镜检查中同时进行这两种手术,从而将手术侵入性和麻醉风险降到最低。
