To investigate the possibility of clinical application of a new technique for myomectomy that involves morcellating the myoma within the myometrium with a new instrument that minimizes invasion of the myometrium and abdominal wall.


In a pilot clinical study, myomectomy was performed on five women with uterine myomas and a normal menstrual cycle using a microwave coagulator and electromechanical tissue borer of our invention. The length of the surgical incisions in the abdominal wall and myometrium, operating time and blood loss were measured.


The mean length of the surgical incisions was 6.3 cm in the abdominal wall and 3.5 cm in the myometrium. The mean operating time was 167 minutes, and the mean blood loss was 312 mL. The length of the incisions in the abdominal wall and myometrium per centimeter of the maximal diameter of the myoma was 0.78 and 0.42 cm, respectively. The incision tended to become smaller in successive operations.


This new technique of myomectomy significantly reduced invasion of the abdominal wall and uterus.
