Out of a total of 81 women who underwent hysteroscopic incision of symptomatic septate uteri during a 5-year period, 70 were analysed with respect to reproductive outcome. Division of the septum was performed with hysteroscopic scissors in 17 patients and by means of the resectoscope in 53. Pre-operative indications included infertility, repetitive pregnancy losses, abnormal uterine bleeding and intractable dysmenorrhoea. There were a total of 51 pregnancies after a mean period of 9.3 months following hysteroscopic metroplasty, of which 29 (56.8%) were carried to term, 12 (23.5%) were spontaneous abortions, and 10 (19.6%) are in progress. The post-treatment pregnancy success rate was 73%. The number of spontaneous abortions, pregnancies to term and mean time between surgery and conception was similar in both groups. There were three cases of perforation in the group of excision with hysteroscopic scissors and a case of pulmonary oedema in the group of the resectoscope. Although different advantages are provided by each technique, and more pregnancies were established using scissors, it seems that operator experience is a major consideration in performing these therapeutic hysteroscopic operations.

Electrosurgical ablation of the endometrium is a therapeutic choice for those patients having abnormal uterine bleeding. When ablation is followed by a hysterectomy, tissue damage due to thermal effect can be seen. From a total of 350 women with endometrial ablation, 12 required subsequent hysterectomy. The histological features found in these specimens are described and related to the elapsed time between the two surgical procedures. The mean elapsed time between ablation and hysterectomy was 19 +/- 17.3 months. Scarring with formation of additional endometrial cavities was seen in five cases, and endocervical stenosis in two cases. In seven patients, endometrial regrowth was seen at hysterectomy. Necrosis, granulomatous and foreign-body giant cell reaction, eosinophilic infiltrate and pigment-containing macrophages in the myometrium were seen in the long-term post-ablation hysterectomies. Necrosis was seen in short period post-ablation hysterectomies. Six of the seven patients with endometrial regeneration had adenomyosis in the hysterectomy specimen. Endometrial ablation induces thermal effects in the endometrium and granulomatous reaction with foreign-body giant cell reaction, fibrosis and deposition of pigment within macrophages in the myometrium. Adenomyosis is a possible explanation for endometrial regeneration in cases of ablation failure.

HSG is still a useful screening test for the evaluation of the uterine cavity in the study of primary or secondary infertility. In addition, HSG provides information concerning the assessment of tubal morphology and patency. We believe that these two procedures are complementary in the evaluation of the uterine cavity.
