Transvaginal ultrasonography in the diagnosis of diffuse adenomyosis

OBJECTIVE To evaluate the diagnostic capability of transvaginal ultrasonography in detecting diffuse adenomyosis. DESIGN We compared the preoperative transvaginal ultrasound (US) findings and the pathological findings of the surgical specimen in a series of women who underwent hysterectomy for menorrhagia. PATIENTS Forty-three women (mean [+/- SD] age of 46 +/- 5) with recurrent menorrhagia and enlarged uterus, without evidence of uterine leiomyomas at abdominal US and of endometrial disease at vabra curettage. SETTING Tertiary care center, university medical school. MAIN OUTCOME MEASURES Sensitivity, specificity, predictive positive and negative values of transvaginal US in the diagnosis of diffuse adenomyosis. RESULTS The sonographer diagnosed adenomyosis in 22 patients, whereas the pathologist found adenomyosis in 20 women, confirming the US findings in 16 cases and making an ex novo diagnosis in 4. The sensitivity of transvaginal US was 80%, the specificity 74%, the predictive value of a normal test 81%, and that of an abnormal test 73%. CONCLUSIONS Transvaginal US seems to represent a real advance in the preoperative diagnosis of diffuse adenomyosis.

Stage and localization of pelvic endometriosis and pain

We analyzed the prevalence of dysmenorrhea, pelvic pain, and dyspareunia in relation to the disease stage in 160 women with endometriosis but no other associated pelvic disease who underwent their first gynecologic surgery (laparoscopy or laparotomy) at the First Obstetric and Gynecology Clinic of the University of Milan between 1985 and 1987. Dysmenorrhea was reported by 78% of the patients, pelvic pain by 39%; and deep dyspareunia by 32%. No relation was found between severity of the pain symptoms and stage of the disease or site of the endometriotic lesions.

Reproductive prognosis after hysteroscopic metroplasty in 102 women: life-table analysis

OBJECTIVE To evaluate reproductive prognosis after hysteroscopic metroplasty. DESIGN The cumulative proportions of women who became pregnant and gave birth, subdivided according to previous obstetric history, were calculated by the product limit method and compared using the log rank test. SETTING Outpatient infertility clinic of Milan University. PATIENTS One hundred two consecutive patients with complete (n = 23) or partial septate uterus (n = 79) referred because of infertility or repeated abortion. INTERVENTION Hysteroscopic metroplasty performed by microscissors (n = 80), argon laser (n = 10), or electroresectoscope (n = 12). MAIN OUTCOME MEASURES Postoperative cumulative pregnancy and birth rates. RESULTS At 36 months the cumulative pregnancy and birth rates were 89% and 75%, respectively, in the septate uterus group and 80% and 67% in the subseptate uterus group. CONCLUSIONS Reproductive prognosis after hysteroscopic metroplasty was favorable and not influenced by the malformation subclass.

Gestrinone versus danazol in the treatment of endometriosis

Thirty-nine infertile patients with laparoscopic diagnosis of endometriosis were allocated randomly to treatment with gestrinone 2.5 mg twice weekly (20 patients) or danazol 600 mg/day (19 patients) for 6 months. If amenorrhea was not obtained after 1 month of treatment, the gestrinone dose was increased to 2.5 mg three times a week (7 patients) and the danazol dose to 800 mg/day (2 patients). One month after the end of the treatment, a repeat laparoscopy was performed only in the women who agreed (7 of the gestrinone treated group, 9 of the danazol group). All of the patients were followed for at least 12 months after the end of the treatment, during which time they attempted to conceive. There was a marked improvement of pain symptoms during the treatment in the patients of both groups. The repeat laparoscopy did not reveal significant differences between the two groups in the reduction of the disease extent. Eighteen months after treatment suspension, the cumulative pregnancy rate was 33% in the patients treated with gestrinone and 40% in those treated with danazol. Pain symptoms recurred during the follow-up in 57% of the gestrinone and 53% of the danazol group. The side effects were more frequent and severe with the danazol treatment, whereas those caused by gestrinone were mostly weight gain and acne. The results of this study suggest that gestrinone is as effective as danazol in the treatment of infertility associated with endometriosis and is better tolerated.

Buserelin versus danazol in the treatment of endometriosis-associated infertility

A total of 62 infertile women with a laparoscopic diagnosis of endometriosis were allocated randomly to two treatment groups, one of which (32 patients) received oral danazol 600 micrograms/day and the other (30 patients) received intranasal buserelin 1200 micrograms/day for 6 months. Suppression of serum levels of estradiol was greater with the gonadotropin-releasing hormone agonist treatment. Pain symptoms improved markedly during treatment in both groups. At the end of treatment a repeat laparoscopy was performed only in the patients who agreed to it (12 in the buserelin group and 13 in the danazol group), and it did not reveal significant differences in the effects of the two treatments on the endometriotic implants. All of the patients were followed up for at least 12 months, during which pregnancy was attempted. At 18 months the cumulative pregnancy rate was 48% in the patients treated with buserelin and 43% in those treated with danazol. Pain recurrence was observed in about half of the patients in each group 1 year after treatment suspension. The side effects were more frequent and more severe in the danazol-treated patients, whereas those given buserelin generally reported only symptoms of hypoestrogenism. The results of this study suggests that buserelin is at least as effective as danazol in the treatment of endometriosis when the outcome is considered in terms of restored fertility, and its side effects are less severe.

Laparoscopy in the diagnosis of gynecologic chronic pelvic pain

Laparoscopy was performed on 126 women with undiagnosed chronic pelvic pain. Abnormalities were demonstrated in 62.7% of the cases. Endometriosis was present in 32.5% of the women. Laparoscopy is useful in the differential diagnosis of chronic pelvic pain and is indicated when symptoms persist for over 6 months.

CA 125 in serum, peritoneal fluid, active lesions, and endometrium of patients with endometriosis.

Ca 125 levels in serum and peritoneal fluid were measured in 39 patients with endometriosis and 18 patients with normal pelvic anatomy at laparoscopy, and the presence of this antigen in endometriotic tissue and endometrial mucosa was also investigated. Serum CA 125 concentrations were elevated in patients with Stage III or IV endometriosis compared with control subjects (32.9 +/- 11.2 versus 16.4 +/- 8.9 U/ml, means +/- SD; p less than 0.001). CA 125 values were greater than 35 U/ml in 36.8% of women with Stage III or IV endometriosis and in none of the control subjects. No significant differences in CA 125 levels in peritoneal fluid were found between patients with endometriosis and control subjects. The immunohistochemical studies found CA 125 in 10% of the endometriotic lesions and 37.5% of the endometrial samples of patients with endometriosis and in 33.3% of the endometrial samples of control subjects.

Use of goserelin depot, a gonadotropin-releasing hormone agonist, for the treatment of menorrhagia and severe anemia in women with leiomyomata uteri

Menorrhagia is the most frequent symptom in women with leiomyomata uteri. We induced transient hypoestrogenism with a gonadotropin‐releasing hormone agonist, goserelin (Zoladex, I. C. I.), in a depot formulation, to resolve severe anemia in 16 women with uterine myomas. Subcutaneous administration of goserelin 3.6 mg was repeated every 28 days for 6 months. Thirteen patients became amenorrheic in 5 weeks and 3 reported scanty bleeding. Estradiol fell to postmenopausal levels after one months treatment with hormonal surges on only three occasions. Uterine volume decreased by 49% after 3 months’ treatment but subsequent reduction was not achieved. Mean hemoglobin rose from 7.4 g/dl pretreatment to 13.2 g/dl at 3 months (+ 78.3%) and mean hematocrit from 26.1% to 39.8% (+52.4%) without any further improvement. Serum ferritin increased constantly during the 6 months. Goserelin depot therapy in severely anemic patients with leiomyomas and menorraghia is practical, safe and may avoid the need for preoperative transfusion.

Structural and ultrastructural defects in preovulatory endometrium of normo-ovulating infertile women with minimal or mild endometriosis

To investigate whether a primary endometrial factor is involved in the pathogenesis of infertility in patients with minimal or mild endometriosis, we compared light, scanning, and transmission electron microscopic studies of preovulatory endometria of 15 endometriotic patients with 12 normal controls. All the women were infertile and normo-ovulating by standard criteria. Six morphometric indexes were considered. The scanning electron microscopic analysis revealed heterogeneity of the endometrial surface epithelium in 77% of the patients with endometriosis and in 16% of the controls. Glandular and stromal mitoses, basal vacuolated cells, and the ciliated:nonciliated cell ratio were significantly reduced in the endometriosis group compared with the controls. Further studies are needed to clarify the role of the observed endometrial anomalies in the pathogenesis of infertility associated with endometriosis.

Re-examination of the anatomic indications for hysteroscopic metroplasty

Until now the indication for hysteroscopic metroplasty has been based on laparoscopic findings and thus depended on the operators experience. Using ultrasound and magnetic resonance images of double uteri it should be possible to find more objective indications for this operation. When three points are identified on longitudinal scans of the uterine fundus, the two tubal ostia and the mid-point of the fundal perimetrium, hysteroscopic metroplasty is indicated only in uteri in which the third point is at least 5 mm above a straight line drawn between the tubal ostia. This classification criterion includes more cases than laparoscopic criteria in this study; we performed hysteroscopic metroplasty in 23 double uteri and had we followed the laparoscopic criteria the operation would have been performed only in 19.
