Abstract
Laparoscopic adenomyomectomies are performed in women with localized uterine adenomyosis with desired fertility. Both monopolar electric knives and Harmonic Scalpels® have been widely used in laparoscopic procedures; however, resection is not always easy, because both adenomyomatic and normal myometrial tissue develop heat degeneration with these devices, and the interface between abnormal and normal tissue is unclear. Here we report a successful adenomyomectomy using a cold knife (Endoscalpel®) following use of a Harmonic Scalpel®. The interface became clearer and the adenomyomatic lesion was resected.
