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 operator's 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.

Intranasal buserelin versus surgery in the treatment of uterine leiomyomata: long-term follow-up.

Forty-two women with symptomatic uterine myomas, candidates for myomectomy or hysterectomy, were randomized to 6 months' treatment with buserelin 1200 micrograms/day intranasally (n = 22) or immediate surgery (n = 20). After buserelin treatment or operation the patients were followed for at least 12 months. Buserelin was well tolerated, the uterine volume fell from 465 +/- 168 to 273 +/- 88 cm3, and hemoglobin values normalized in all anemic patients. Rapid myoma regrowth was observed in all patients in the buserelin group after treatment withdrawal. Pregnancy occurred during follow-up in one of five buserelin-treated myomectomy candidates. Menorrhagia recurred in eight of 15 buserelin-treated hysterectomy candidates, and a hysterectomy was required but no transfusion was needed. Two women entered natural menopause and were considered cured. In the surgery group all operations were uneventful: three women conceived after myomectomy, whereas four of the patients that underwent hysterectomy required transfusions. Thus buserelin treatment appears to be indicated for infertile patients when surgery is contra-indicated or could cause adhesions, and for hysterectomy candidates in perimenopausal age and/or with secondary anemia.

Pelvic denervation for chronic pain associated with endometriosis: fact or fancy?

The efficacy of presacral neurectomy and amputation of the uterosacral ligaments in the treatment of chronic pelvic pain has been debated for decades. These procedures used to be done mainly in women with normal pelves, but more recently they have been performed during conservative surgery for treatment of endometriosis. In the 1980s the rapid spread of laparoscopic surgery has led to an increasing number of endoscopic denervations in patients with chronic pelvic pain associated with endometriosis. However, an analysis of literature data has failed to prove that presacral neurectomy and amputation of the uterosacral ligaments are effective and did not demonstrate better results with the use of lasers rather than electrocoagulation. Moreover, no valid comparison has yet been made between laparotomy and laparoscopic methods.

Argon laser versus microscissors for hysteroscopic incision of uterine septa.

We performed hysteroscopic metroplasty in 21 women with repeated abortion and subseptate uterus. The patients were randomly allocated to septal incision with the argon laser (group I, 10 subjects) or microscissors (group II, 11 subjects) to compare these instruments in terms of surgical feasibility and anatomic results. The mean operating time was 57% longer in group I than in group II (p = 0.001), the intra- and postoperative morbidity of the whole series was negligible, and the anatomic results at abdominal ultrasonography and hysteroscopy performed 2 months postoperatively were similar in the two groups. This study confirms that microscissors are the simplest, fastest, most effective, and least expensive instrument to correct a septate uterus. The complete agreement of the findings at follow-up hysteroscopy and ultrasonography suggest the use of the latter as the method of choice to check the surgical results.

Oral contraceptive use and the risk of ovarian cancer: an Italian case-control study.

The association between oral contraceptive (OC) use and the risk of ovarian cancer was analysed in a case-control study, conducted between 1985 and 1989 on 505 epithelial ovarian cancer cases under 60 years of age, and 1375 controls in hospitals for a spectrum of acute conditions, not gynaecological, hormonal or neoplastic, apparently unrelated to OC use. 41 (8.1%) women with epithelial ovarian cancer and 192 (14.0%) controls reported OC use. The multivariate relative risk (RR) for ever use was 0.7 (95% confidence interval (CI) = 0.5-1.0). The risk decreased with duration of use: compared with never users the multivariate RRs were 0.9 and 0.5 respectively for less than 2 years and 2 years or more users (chi 2(1) trend = 6.17, P = 0.01). The risk of ovarian cancer decreased with recency and latency of use: the estimated RR were 0.5 and 0.9 in women reporting last OC use less than 10 or 10 years or more from the diagnosis of the disease, and 0.6 and 0.8 in those reporting first OC use less than 10 or 15 or more years before. The protective effect of OC was consistent in separate strata of selected covariates, including parity and other major known or suspected risk factors for ovarian cancer. There was some indication that the protection declines with advancing age, but the risk estimates were similar in premenopause and postmenopause.

Reproductive factors and risk of endometrial cancer.

The role of reproductive factors in endometrial cancer risk has been analyzed in a case-control study conducted since 1983 in the greater Milan area on 568 women (cases) with histologically confirmed endometrial cancer and 1925 women (controls) who were admitted for acute, nonmalignant, hormonal, gynecologic conditions to hospitals that cover a comparable catchment area. Compared with nulliparous women, parous women had a 30% lower risk of endometrial cancer, but there was no evidence of a decline in risk with increasing number of births. The risk of the disease decreased with number of spontaneous or induced abortions; the multivariate relative risk estimates were, compared respectively with no spontaneous or induced abortions, 0.5 for women with two or more spontaneous abortions and 0.3 for women with two or more induced abortions; both trends in risk were statistically significant. When parous women only were considered, no association emerged between endometrial cancer and age at first birth, but the risk decreased with increasing age at last birth: compared with women whose last birth occurred before age 25, the relative risk was 0.5 for women who were greater than or equal to 35 years old at last birth, and the multivariate trend in risk was statistically significant. For most of the reproductive factors that were considered, the risk estimates tended to be greater at younger age or among premenopausal women and to flatten off in subsequent strata of age. An association between endometrial cancer and age at first birth was observed in women who were less than or equal to 49 years old, but not in older groups. The observation that later age at last birth as well as later first birth in younger women decreases the risk of endometrial cancer suggests a short-term protective effect of pregnancy. This finding is consistent with a late-stage (promotional) effect of reproductive factors on endometrial carcinogenesis.

Secretory changes in preovulatory endometrium during controlled ovarian hyperstimulation with buserelin acetate and human gonadotropins.

Twenty-one patients with unexplained infertility underwent controlled ovarian hyperstimulation with buserelin acetate and human menopausal and chorionic gonadotropins, and follicular growth was monitored by ultrasonography and daily 17 beta-estradiol (E2) assays. Endometrial biopsy was performed when E2 levels were greater than or equal to 250 pg/mL per follicle and the follicular diameter was greater than or equal to 17 mm. As controls, we studied 20 preovulatory endometrial biopsies from patients with a male infertility factor. The biopsy material was examined at light, scanning, and transmission electron microscopes, and a morphometric analysis was performed. Preovulatory endometrial mucosa during controlled ovarian hyperstimulation showed accentuated proliferative aspects in both the glandular and stromal components and more frequent early secretory phenomena compared with the controls. The preovulatory progesterone (P) levels observed in our study seem to exclude the possibility that such early secretory aspects of the hyperstimulated endometrium are because of higher P concentrations in patients compared with controls.

Risk factors for spontaneous abortion.

A case-control study was conducted to evaluate risk factors for spontaneous abortions. Cases were 94 women with two or more unexplained miscarriages (after exclusion of genetic, endocrine and Müllerian factors) and no term pregnancy, controls were 176 women admitted for normal delivery to the same clinic where cases were identified. Questions were asked about personal characteristics and habits, and gynaecological history. A family history of recurrent miscarriage was more common among women with spontaneous miscarriages than among the controls (13 cases versus 8 controls, relative risk (RR) = 3.2, 95% confidence interval (CI) = 1.3-8.1). Compared to women whose menarche occurred at age 11 or younger, the RRs were 0.8 when menarche occurred at age 12-13 and 0.5 at age 14 or more: this trend in risk was statistically significant. Compared with never smokers, current smokers had about a 40% increased risk of miscarriage and the risk increased with number of cigarettes per day. No association emerged with sociodemographic characteristics (e.g. education, marital status, age of the partner), reproductive history (age at first pregnancy), type of contraceptive used and other general lifestyle habits (e.g. alcohol or coffee consumption).

Conservative surgical treatment for severe endometriosis in infertile women: are we making progress?

Conservative surgery for severe endometriosis in infertile women is one of the most challenging situations for the pelvic surgeon. The second half of the 1980s saw an increase in the supporters of laparoscopic treatment even for more extensive disease. Two opposing factions were thus created: traditional gynecologic surgeons who accuse endoscopists of imprudence and technical inadequacy and enthusiastic supporters of operative laparoscopy who consider laparotomy obsolete and its associated morbidity needlessly high for the patient and health service. In the present review of the literature data we analyze laparotomy and laparoscopy techniques and compare the postoperative results in terms of reproductive success in an attempt to clarify whether conservative endoscopic treatment of severe endometriosis is only an inappropriate proposal with no future or whether, due to its efficacy, it will eventually limit interventions via laparotomy to exceptional circumstances.

Trends in multiple births in Italy: 1955-1983.

On the basis of the numbers of single and multiple births routinely collected by the Central Institute of Statistics, trends in multiple births in Italy over the period 1955-1983 were analyzed. Between 1955 and 1983 the frequency of multiple births declined by about 25% (from 12.6/1000 deliveries to 9.6/1000 deliveries). The downward trend was constant until the early 1970s when rates tended to level off and increase slightly. This finding was largely attributable to trends in dizygotic rates, monozygotic births being approximately constant over the period considered. Multiple birth rates rose till age 35-39, being more than two times higher in this age group than in teenagers, but flattened off in the subsequent strata of age: this finding was constant over the period considered. Despite the general decreasing trend, the regional differences persisted largely unchanged, multiple birth rates being about 30% higher in Southern (and less developed areas) of the country than in the North of Italy. Geographic differences were limited to dizygotic pregnancies, monozygotic rates being constant (about 4/1000 pregnancies) in various areas.

Risk of recurrence after myomectomy.

The risk of recurrence of uterine myomas was analyzed in 622 patients who underwent myomectomy between 1970 and 1984 at the First Department of Obstetrics and Gynecology of the University of Milan. The cumulative 10-year recurrence rate was 27%, and this increased steadily up to the end of the observation period. Differences were not observed in frequency of recurrence by age at diagnoses or by the site of the myomas at surgery. Patients with a single myoma tended to experience a lower rate, but this finding was not statistically significant. Women who gave birth to a child after myomectomy had a 10-year recurrence rate of 15%, against 30% for those who did not; this difference was statistically significant.

Peritoneal endometriosis. Morphologic appearance in women with chronic pelvic pain.

A prospective study analyzed the prevalence and severity of dysmenorrhea, intermenstrual pain and deep dyspareunia in relation to morphologic features of peritoneal disease in 73 consecutive women with endometriosis but no associated pelvic pathology, previous pelvic surgery or hormonal treatment. All underwent their first laparoscopy for chronic pelvic pain at the First Department of Obstetrics and Gynecology, University of Milan, Milan, Italy, between 1986 and 1989. Gynecologic pain symptoms were evaluated with a verbal score and visual analog scale. Peritoneal lesions were classified as typical (black nodules, yellow-brown patches, stellate scars), atypical (clear vesicles, clear or red papules, red polypoid lesions) or mixed. When the three types of lesions were considered together, a statistically significant association was observed only with deep dyspareunia (P less than .01). Moreover, a significantly higher prevalence of deep dyspareunia was revealed in patients with typical versus atypical lesions (P less than .01) and in those with mixed versus atypical lesions (P less than .05). Fresh, papular, atypical lesions exposed to peritoneal fluid might cause functional pain, whereas "old," black nodules immersed in infiltrating scars might provoke mainly organic pain.

Early detection of ectopic pregnancy. Use of a sensitive urine pregnancy test and transvaginal ultrasonography.

We performed a prospective study to evaluate the reliability of a rapid monoclonal antibody urine pregnancy test with a sensitivity limit of 20 mIU/mL combined with transvaginal ultrasonography in the early diagnosis of ectopic pregnancy in 116 women with subacute pelvic pain and a stable general condition. The diagnosis of tubal pregnancy was confirmed with laparoscopy in 100 of the 103 women with positive sensitive urine pregnancy tests and no intrauterine gestational sac at transvaginal ultrasonography. Laparoscopy revealed a hemorrhagic corpus luteum in four of the eight subjects with negative monoclonal antibody pregnancy tests and no intrauterine gestational sac, an ovarian cyst in three and a normal pelvis in one. Of the five women with a positive pregnancy test and an intrauterine gestational sac, two had a hemorrhagic corpus luteum, two a normal pelvis and one a tubal pregnancy at laparoscopy. The sensitivity of a monoclonal antibody urine pregnancy test and transvaginal ultrasonography combined for the diagnosis of ectopic pregnancy was 99%, and the specificity was 80%, with positive and negative predictive values of 97% and 92%, respectively.

Repetitive conservative surgery for recurrence of endometriosis.

We evaluated the recovery of fertility and the relief of pain symptoms in a long-term follow-up of 42 women undergoing repetitive conservative surgery for recurrent endometriosis. The mean age of the patients was 31.1 +/- 4.3 years. At the time of their second operation the disease was stage IV in 14 women, stage III in 25, and stage I in three. After reoperation, the patients were followed for a mean period of 41.8 +/- 30.3 months. Pain symptoms returned in eight women, dysmenorrhea and deep dyspareunia in eight, and pelvic pain in seven. Eight of the 28 women (28.6%) who attempted to conceive achieved a total of 13 pregnancies. The corrected pregnancy rate was 35%, and the cumulative rate at 27 months was 30.7%. A third operation was necessary in six women after a mean period of 35 months. Conservative surgery is an effective therapeutic option for infertile patients with recurrent endometriosis.

Transvaginal ultrasonography versus hysteroscopy in the diagnosis of uterine submucous myomas.

Seventy-one women with symptomatic uterine myomas, hospitalized for hysterectomy, underwent preoperative transvaginal ultrasonography and hysteroscopy to compare their reliability in the diagnosis of submucous myomas. After the operation, the surgical specimen was studied carefully and the results were compared with the preoperative diagnostic findings. Transvaginal ultrasonography had a sensitivity of 100% and specificity of 94%; the predictive value of an abnormal ultrasound scan was 81% and that of a normal one was 100%. The sensitivity of hysteroscopy was 100% and the specificity 96%; the predictive value of an abnormal hysteroscopic finding was 87% and that of a normal result was 100%. Mapping of uterine myomas is more precise with transvaginal ultrasonography than with hysteroscopy, but the former method cannot distinguish between a myoma and an endometrial polyp.

Inguinal endometriosis: pathogenetic and clinical implications.

In six women with a preoperative diagnosis of incarcerated hernia, surgical exploration of the groin revealed inguinal endometriosis and no hernia. The affected structure was always the extraperitoneal portion of the round ligament. Six of the seven lesions were on the right. Intraperitoneal endometriosis was demonstrated in all patients. Catamenial pain was the pathognomonic symptom in the differential diagnosis of the inguinal mass. Gynecologists and surgeons should bear in mind the possibility that endometriosis may be the cause of symptoms of a suspected incarcerated inguinal hernia. Should this disease be detected at inguinal exploration, a laparoscopy is indicated during the same operation.
