The Efficacy of G-CSF Against Adhesion Reformation After Hysteroscopic Adhesiolysis

After hysteroscopic adhesiolysis, patients with moderate to severe intrauterine adhesions will be allocated into 2 groups randomly, with COOK ballon and estrogen and progesterone sequential therapy given to prevent adhesion routinely. 7 day later, G-CSF or normal saline will be injected into the uterine cavity by Tom catheter after removing the balloon respectively. A second hysteroscopic examination will be performed in 2 months to check up the adhesion reformation. In addition, the endometrial thickness after surgery and fertility outcome will be followed up.
