Successful ovarian tissue cryopreservation with transvaginal natural orifice transluminal endoscopic surgery: A case report
WOMENS HEALTH(2024)
Abstract
Chemotherapy and radiation therapy can cause gonadal dysfunction in women of reproductive age. Ovarian tissue cryopreservation is performed to restore fertility by allowing transplantation of the patient's frozen-thawed ovarian tissue or through future in vitro maturation and in vitro fertilization of frozen-thawed oocytes. Herein, we describe our initial experience with vaginal natural orifice transluminal endoscopic surgery for ovarian tissue preservation in a young woman with malignant tumor. A 23-year-old woman with anaplastic lymphoma kinase-positive malignant lymphoma was scheduled for hematopoietic stem cell transplantation after experiencing relapse following R-cyclophosphamide, doxorubicin, vincristine, and prednisolone therapy. Ovarian tissue cryopreservation was selected as only MII2 oocytes were collected. Vaginal natural orifice transluminal endoscopic surgery was performed to excise the left ovary. Ovarian tissues were frozen using the vitrification method. The operative time was 37 min, and blood loss was minimal. Pathological examination revealed no metastatic findings of malignant lymphoma and no thermal damage to the ovarian tissue due to bipolar disorder. The patient was discharged on the first day postoperatively, and her postoperative course was uneventful. The vaginal natural orifice transluminal endoscopic surgery technique can provide a safe and effective alternative to laparoscopy or laparotomy for the cryopreservation of ovarian tissue in young patients with cancer. We believe this method has potential application in sexually mature female cancer survivors. Ovarian tissue cryopreservation with vaginal natural orifice transluminal endoscopic surgeryChemotherapy and radiotherapy can affect a woman's ability to have children by reducing ovarian function. This can make it hard to conceive even with fertility treatments. Freezing healthy ovaries before these treatments can help restore fertility. This can be done by freezing and later transplanting ovarian tissue or by fertilizing frozen eggs in a lab. Traditional surgery to remove ovaries can cause cosmetic issues and pain. But now, a new method called vaginal spontaneous opening transperitoneal endoscopic surgery is becoming more common. This surgery is less invasive, quicker, and causes less bleeding. We recently used this method to preserve ovarian tissue in young women with cancer. The surgery was successful with minimal complications. This new approach could offer a safer option for preserving fertility in female cancer survivors.
