Abstract

A curved microwave applicator was specifically developed for microwave endometrial ablation for the uterus with distorted cavity. The applicator was transcervically introduced to a uterine cavity of a surgical specimen with an intramural myoma node and adenomyosis, and 11 sites on the endometrium were coagulated by microwaves. The endometrium and neighboring myometrium 7mm in depth were degenerated at a power of 70W with a duration of 50sec. The endometrium at the cornus was found fully destroyed. Temperature increased less than three Celsius degrees on the serosal surface of the uterus at the end of microwave coagulation procedure. It is highly feasible to use the curved applicator for uteri enlarged with intramural or submucosal myomas in clinical setting.
