Robotic-assisted uterine transposition followed by anatomic pelvic repositioning for a patient with intramural fibroids and rectal cancer

Abstract

Objective: To report the first described case of robotic-assisted utero-ovarian transposition followed by anatomic repositioning in the pelvis and cervicovaginal anastomosis in a woman with uterine fibroids, which was performed for fertility preservation in the context of pelvic radiation for rectal cancer.

Design: Description of technique and live-action narrated surgical footage showing uterine transposition and repositioning.

Setting: University hospital.

Patients: A 36-year-old woman with a new diagnosis of cT3N2M0 rectal adenocarcinoma planned for neoadjuvant chemotherapy and pelvic radiation and desired fertility preservation permissive of future pregnancy. A transvaginal ultrasound revealed a 5-cm posterior leiomyoma and a normal endometrial cavity. The patient elected for utero-ovarian transposition before chemoradiation. The patient included in this video gave consent for publication and posting of the video online, including on social media, the journal website, scientific literature websites, and other applicable sites. Per institutional guidelines, an Institutional Review Board review was not required.

Interventions: Robotic-assisted utero-ovarian transposition was performed in an inpatient setting 2 weeks after ovarian stimulation and oocyte retrieval. She was given a gonadotropin-releasing hormone agonist for menstrual suppression after oocyte retrieval. The uterus and adnexa were transposed en bloc to the upper abdomen, with perfusion via retroflected infundibulopelvic ligaments. Intravenous indocyanine green was administered intraoperatively to visualize uterine perfusion. Three weeks postoperatively, the patient underwent surgical management of small bowel obstruction, which was successfully managed with laparoscopic adhesiolysis. The patient subsequently completed chemoradiation and had a complete response to the rectal tumor. She therefore elected for surveillance. Seven months after transposition and 2 months after completion of treatment, the patient underwent uncomplicated robotic-assisted utero-ovarian anatomic repositioning in the pelvis with cervicovaginal anastomosis. Chromopertubation confirmed tubal patency.

Main outcome measures: Restoration of normal pelvic anatomy and resumption of reproductive physiology.

Results: At her 4-month postoperative visit, the cervix and vagina were normal in appearance. The patient reported the return of spontaneous menses and sexual activity without complications.

Conclusion: This case is unique because of the presence of bulky intramural uterine fibroids. The described technique may be useful for selected cancer patients who desire to carry a pregnancy after pelvic radiation for cancer treatment, and demonstrates that patients considering utero-ovarian transposition need not be excluded solely on the basis of the presence of uterine fibroids.
