groups, laparoscopy use group (Lap) and no laparoscopy use group (non-Lap)
determined by the use of laparoscopy. The ultrasound parameters analyzed between
these groups included maximal diameter of gestational sac, presence of fetal
heartbeat, local myometrial thickness and grading of color Doppler signals.

groups was 2.330
