OBJECTIVE: To investigate the possibility of clinical application of a new
technique for myomectomy that involves morcellating the myoma within the my
ometrium with a new instrument that minimizes invasion of the myometrium an
d abdominal wall.
STUDY DESIGN: In a pilot clinical study, myomectomy was performed on five w
omen with uterine myomas and a normal menstrual cycle using a microwave coa
gulator 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.
RESULTS: The mean length of the surgical incisions was 6.3 cm in the abdomi
nal wall and 3.5 cm ill the myometrium. The mean operating lime tons 167 mi
nutes, and the mean blood loss was 312 nit. 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 becom
e smaller in successive operations.
CONCLUSION: This new technique of myomectomy significantly reduced invasion
of the abdominal wall and uterus.
