Hysteroscopic septum resection in patients with recurrent abortions or infertility.

Fifty-seven patients who underwent hysteroscopic septum resection between January 1991 and December 1996 were studied; nine patients presented with recurrent abortions, 46 with infertility (26 primary and 20 secondary), one with dysmenorrhoea and one with an asymptomatic complete septum. Their reproductive history included 78 pregnancies: 69 (88.4%) abortions, two (2.6%) ectopics, two (2.6%) preterm deliveries and five (6.4%) term deliveries. In patients with infertility, the incidence of unexplained infertility was 19.6% and the incidence of endometriosis was 26.1%. After hysteroscopic septum resection, 42 patients were interested in pregnancy. All patients with recurrent abortions conceived spontaneously. Twenty-one (63.6%) infertile patients achieved a pregnancy, 13 (61.9%) of them after treatment with various assisted reproduction techniques. The reproductive outcome after septum resection yielded 44 pregnancies, including three sets of twins and one set of triplets reduced to twins: 11 (25%) abortions, one (2.3%) ectopic pregnancy, two (4.5%) preterm deliveries (both twins), 28 (63.7%) term deliveries and two (4.5%) as-yet ongoing pregnancies. It seems that the hysteroscopic treatment of uterine septum has a beneficial effect on pregnancy outcome. A septate uterus does not seem to be an infertility factor. The achievement of pregnancy is normal in patients with recurrent abortions, while the chances of conception in patients with infertility seem to be similar to those for the general infertile population.
