ObjectiveTo explore the effects of direct visualization induced abortion system on endometrium after intrauterine operation.

Methods One hundred induced abortion women with the first pregnancy, embryonic arrest detected by ultrasound, ASA class Ⅰ, age18 to 35 years old, pregnant time G1P0, menopause time 55-75 d, were investigated.According to the sequence of numbers randomly generated by computer and parity of numbers, the cases were divided into the ultrasound-guided induced abortion group(B group) and direct vision abortion system group(group V) (50 cases in each group).The endometrial thickness, operative complications and menstrual cycle recovery after abortion were compared between two groups.

ResultsCompared with the group B, the deeper endometrial thickness, less intraoperative blood loss, shorter postoperative bleeding time, shorter postoperative menstrual recovery time and higher proportion of normal menstruation in group V were found(P < 0.05 to P < 0.01).The differences of the duration of surgery and anesthesia, abortion syndrome, uterine perforation and cervical adhesions between two groups were not statistically significant(P>0.05).

ConclusionsCompared with the ultrasound-guided abortion, the direct visualization induced abortion system can protect the endometrium, the intraoperative bleeding significantly reduces, the postoperative bleeding time is significantly shortened, the menstrual recovery time is significantly shortened, the endometrium is thicker after surgery, the proportion of normal menstrual volume is higher, and which does not increase the incidence rates of intraoperative and postoperative complications.
