Complications Following Extended Freeze Endometrial Cryoablation in Uteri with Previous Uterine Incisions: A Case Report.

Background: Endometrial cryoablation causes cryonecrosis of the endometrial lining as treatment for abnormal uterine bleeding in premenopausal women who have no desire for future fertility. Extended freezes to potentially improve efficacy have been described in the literature, although no associated complications have been reported.
Case: We present 2 cases of ureteral stricture and sigmoid colon perforation in separate patients following extended freeze cryoendometrial ablation. Both patients had a preexisting uterine scar from prior cesarean section or myomectomy.
Conclusion: Patients with a prior uterine incision may be at increased risk for complications from extended freeze endometrial cryoablation.
