To compare the short-term curative effects of HEOS by sharp separation method and the traditional method of separation of two kinds of hysteroscopic intrauterine adhesions by HEOS, to investigate the clinical value of hysteroscopy sharp separation method.

From Jan. 2016 to Apr.2017 were severe intrauterine adhesions were randomly divided into study group (30 cases) and control group (30 cases), research HEOS group with sharp separation hysteroscopic surgery, the control group used traditional hysteroscopic electrosurgery dissection. Two groups were treated with uterine cavity placed cook balloon stent and postoperative estrogen, progesterone artificial cycle therapy for 3 months; after 1, 3 months of hysteroscopic examination; After 1, 3, 6 months the 1 follow-up.

In the study group and the control group after 3 recovery of uterine cavity form the total effective rate was 83.3% (25/30), 56.7% (17/30); menstruation improved the total effective rate was 93.3% (28/30), 70% (21/30); postoperative 1, 3 of the uterine cavity the adhesion recurrence rate was 20% (6/30), 46.7% (14/30) and 13.3% (4/30), 36.7% (11/30); there was significant difference between the two groups (P< 0.05, P<0.05). The postoperative pregnancy rate was 36.7% (11/30), 20% (6/30), there was no significant difference between the two groups (P>0.05). The two groups in operation time, amount of bleeding, uterine fluid absorption difference was statistically significant (P<0.05).

Two different methods of separation of intrauterine adhesion effect had significant difference, HEOS by the sharp separation method is a worthy effective methods for the treatment of severe uterine cavity.
