Optimal waiting period for subsequent fertility treatment after various hysteroscopic surgeries.

OBJECTIVE: To investigate the endometrial wound healing duration after a hysteroscopic surgery.

DESIGN: Prospective study.

SETTING: Tertiary university hospital.

PATIENT(S): One hundred sixty-three women who underwent hysteroscopic surgeries for endometrial polyp (n = 37), submucous myoma (n = 65), uterine septum (n = 16), and intrauterine adhesion (IUA; n = 45).

INTERVENTION(S): Postoperative office hysteroscopy was consecutively done until complete endometrial wound healing. If there was newly formed IUA occurring at the endometrial wounds, adhesiolysis was immediately done with the tip of the office hysteroscope.

MAIN OUTCOME MEASURE(S): Office hysteroscopic inspection of endometrial wound healing and the presence of newly formed IUA.

RESULT(S): Thirty-two of 37 women (86%) achieved a fully healed endometrium 1 month after polypectomy, a higher rate than those after myomectomy (18%), septal incision (19%), and adhesiolysis (67%). Postoperative office hysteroscopy revealed that 88% and 76% of the women had new IUA formation after septal incision and adhesiolysis, respectively, more than those after myomectomy (40%) and polypectomy (0%). Women with postoperative new IUA formation were less likely to achieve endometrial wound healing within 1 month compared with those who had no new IUA formation (31% vs. 61%).

CONCLUSION(S): The duration of endometrial wound healing is different after various hysteroscopic surgeries. Postoperative new IUA formation is an important factor influencing endometrial wound healing.
