Feasibility of laparoscopic ovarian tissue cryopreservation after open abdominopelvic tumor surgery.

Background: Laparoscopic oophorectomy with tissue cryopreservation (OTC) for fertility preservation is usually performed prior to therapy. When fertility preservation is considered after prior open abdominopelvic tumor surgery there may be a perceived barrier to laparoscopic OTC. This study evaluates the feasibility of OTC with a laparoscopic approach after open surgery.
Methods: This is a single institution retrospective study from 2011 to 2019.
Results: Planned laparoscopic OTC was performed after open surgery in 17 of 113 patients. Median age was 4.2 years. The most common diagnoses were Wilms Tumor (35%) and neuroblastoma (35%). The most common procedures were nephrectomy (41%) and exploratory laparotomy with biopsy (35%). The median amount of time between open surgery and OTC was 29 days. Sixteen (94%) had a laparoscopic OTC. Regardless of operative technique, patients resumed therapy a median of 3 days after OTC.
Conclusions: Prior abdominopelvic surgery should not be a barrier to OTC. Laparoscopic OTC is feasible after a variety of open oncologic operations, regardless of time-interval between the procedures and without incurring a significant delay in resuming oncologic therapy.
