[Role of hysteroscopy in the diagnosis and treatment of infertility].
UTERINE DISORDERS: Because they can prevent implantation, anomalies within the uterine cavity play an important role in fertility. The uterine disorders most often observed during hysteroscopy and implicated in infertility are adhesions, septa, polyps, submucous myomas, adenomyosis, endometritis, anomalies of the cervical canal, and lesions of the uterotubal junction.
Hysterosalpingography can be used to evaluate tubal permeability but provides inadequate information about the uterine cavity (numerous false-positives and false-negatives). Pelvic ultrasound is especially helpful for diagnosing interstitial anomalies in the uterus.
Diagnostic hysteroscopy also has a place in infertility investigations, for it allows direct visualization of the uterine cavity, the endometrial mucus (endometritis, adenomyosis), and the cervical canal. The examination is practiced on a out-patient basis, without anesthesia, using appropriate small-caliber instruments and irrigation with physiological saline. Surgical hysteroscopy is used to treat these anomalies. Patients receive general anesthesia. A high-frequency, low-voltage electric current is used, and glycine for irrigation. This procedure allows resection of submucous myomas and polyps and of septa and adhesions. Some groups use laser beams and irrigation by physiological saline for these treatments. Coagulation of a superficial focal spot of adenomyosis is not useful in infertility therapy.


RESULTS
As assessed by the percentage of patients with each indication who subsequently became pregnant, the results of surgical hysteroscopy have been satisfactory: 62 per cent (%) of cases after myomectomy, 66% after section of uterine septa, and 61% after treatment of complicated adhesions. A new exploration of the uterine cavity will be necessary sometime after the surgery to verify the absence of any iatrogenic disorders (adhesions, myomatous fragments).
