Reproductive outcome following hysteroscopic lysis of intrauterine adhesions: A result of 65 cases at Ramathibodi Hospital

Abstract

We reported the reproductive outcome of 65 patients with varying degrees of IUAs who underwent hysteroscopic adhesiolysis between August 1994 and December 1996 at Ramathibodi Hospital. Of the 65 patients treated, 29 had mild adhesions, 26 had moderate adhesions, and 10 had severe adhesions. Adhesions were lysed with hysteroscopic scissors in 25, with biopsy forceps through hysteroscope in 10, with electrosurgery using a monopolar probe in 22 patients, and with resectoscope in 8 patients. The mean duration of the procedure was 15±2.1 minutes. The mean follow-up was 12±1.4 months. Of the 44 patients who originally presented with secondary amenorrhea, 40 (90.9%) have normal menses, 4 (9.1%) have hypomenorrhea. Of the 6 patients who had hypomenorrhea, 5 (83.3%) have normal menses. Cyclic abdominal pain disappeared after treatment in all patients. Of the 45 patients with IUAs and infertility, 16 (35.6%) conceived. Two (20%) of the infertile patients with initially severe adhesions conceived. Of the 5 patients with RPL treated, delivered a full term baby and the other delivered a premature baby at 29 weeks of gestation. All 18 patients who delivered, had live births. Adhesion reformation was absent in patients with initially mild and moderate adhesion but occurred in 2 out of 10 (20%) patients with severe adhesions. These two patients initially suffered from secondary amenorrhea but reported hypomenorrhea after surgery. Both of them had tuberculosis of the genital tract. There were no serious complications occurring in all 65 procedures. All 65 patients were discharged a few hours after the operation.
