    Young patients with early endometrial cancer have a strong desire to retain reproductive function, which require us to develop a therapeutic method that can not only assure the complete resection of tumor but also retain the uterine integrity. In the present study, we proposed a fertility-sparing surgery option that combined hysteroscopic resection with cryoablation to achieve this goal. To verify the safety and effectiveness of cryoablation for local uterine wall, we designed the experiment in pig model using a novel cryoablation balloon probe. In the process of freezing and thawing, the temperature of different parts of the uterus was measured in real time. The uterus was harvested immediately, three weeks after cryotherapy for histological evaluation. The results demonstrated cryoablation using the new cryoprobe is safe and effective. The effective freezing range can cover a range of 2 cm in diameter at least. This study provided us evidence before cryoablation could be applied in clinical practice of fertility-sparing treatment for young women with early endometrial cancer. Copyright © 2020 Elsevier Inc.
