PURPOSE: to evaluate the histological differentiation pattern in superficial peritoneum lesions and in deeply infiltrating endometriosis (DIE) in utero-sacral ligament, bowel (rectum and sigmoid colon) and rectovaginal septum. METHODS: this prospective non-randomized study included 139 patients. Of the total, 234 biopsies were obtained (179 with DIE - Deeply Group - and 55 superficial endometriosis - Superficial Group). From the 179 DIE lesions (Depply Group), 15 were obtained from rectovaginal septum, 72 from rectosigmoid nodules and 92 from utero-sacral ligament. Biopsies were classified in well-differentiated glandular pattern, undifferentiated glandular, mixed glandular differentiation and pure stromal disease, based on specific morphological classification. RESULTS: in the Depply Group (DIE), 33.5% of the biopsies showed undifferentiated glandular pattern and 46.9% mixed glandular pattern. In the Superficial Group, there was the predominance of the well-differentiated glandular pattern (41.8%). Comparing specifically the different localizations of the biopsies of DIE lesions (Deeply Group), a predominance of mixed pattern in bowel nodules (61.1%) was noted. CONCLUSIONS: it was possible to conclude that there is a predominance of well-differentiated glandular pattern in superficial endometriosis, a predominance of mixed undifferentiated in deeply pelvic endometriosis and, specifically studying endometriosis from the rectum and sigmoid colon, there was a predominance of the mixed pattern.

PURPOSE: to analyze the macroscopic and histological changes that occur with the use of sinvastatin in experimental endometriosis in female rats. METHODS: forty Wistar female rats were submitted to the technique of uterine self-transplant in mesenterium. After three weeks, 24 of them developed experimental endometriosis grade III, and were divided in two groups: one group received sinvastatin orally (20 mg/kg/day) and the other (control group) received 0.9% of sodium chloride orally (1 mL/100 g of body weight/day). Both groups received gavage for 14 days, followed by death. The implant volume was calculated [4pi (lenght/2) x (width/2) x (height/2)/3] at the surgical intervention and after the animal’s death. The self-transplants were removed, dyed with hematoxylin-eosin and analyzed by light microscopy. The Mann-Whitney’s test was used in the independent samples and the Wilcoxon’s test for the related samples. The Fisher’s exact test was used for the histological evaluation, with a significance level of 5%. RESULTS: the difference between groups of the initial average volumes of the self-transplants was not significant (p=1.00), but became significant for the final average volumes (p=0.04). There was a significant increase (p=0.01) between the initial and final average volumes in the control group, and a no significant decrease in the sinvastatin group (p=0.95). Histologically, the sinvastatin group (n=9) presented seven cases (77.8%) of moderately preserved and two cases (22.2%) of well preserved epithelial wall, while the control group (n=12) presented seven cases (58.3%) of moderately preserved and five cases (41.7%) of well preserved epithelial wall. CONCLUSIONS: sinvastatin prevented the growth of experimental endometriosis. Studies with sinvastatin for longer periods are promising.

PURPOSE: to identify the incidence and associated factors of surgical scar endometriosis. METHODS: a retrospective cohort observational study performed from the medical records of female patients attended at the Clinical Hospital of Univesidade Federal de Minas Gerais (UFMG) with histopathological diagnosis of scar endometriosis from May 1978 to December 2003. RESULTS: a total of 72 patients were included in the study. The incidence of scar endometriosis after cesarean section was significantly higher than after episiotomy (0.2% and 0.06%, respectively; p<0.00001) with relative risk of 3.3. The women’s age, when diagnosed, ranged from 16 to 48 years old, (mean=30.8 years old). The scar location varied according to the previous surgery: 46 scars after cesarean sections, one after hysterectomy and one after abdominal surgery (48 lesions in the abdominal wall); 19 scars after episiotomy, one because of relapse and two after pelvic floor surgeries (22 pelvic wounds); two women had not been submitted to previous gynecological surgery (one umbilical endometrioma and one lesion in the posterior vaginal wall). Pain was the most frequent symptom (80%), followed by a node (79%) and, in more than 40%, the pain and the node suffered modification with menstruation. Other less frequent complaints were: dyspareunia, secondary infertility, pelvic pain, dysmenorrhoea, scar secretion, menorrhagia pain when evacuating. The mean time observed between the surgery and the beginning of the symptoms was of 3.7 years. The average size of the endometriomas was 3.07 cm. The diagnosis based on clinic evaluation was correct in 71% of the cases. The choice of treatment in all the cases was the surgical excision. In only one incident there was relapse and new intervention. CONCLUSIONS: scar endometriosis is a rare situation originated, in most cases, after obstetrical surgical procedure, with higher risk after cesarean section. It is a highly suggestive clinical condition, with a rare necessity of complementary diagnostic procedures, and the best treatment choice is the surgical excision.

PURPOSE: to assess the level of lipid peroxidation (LP) and vitamin E in the follicular fluid and serum of infertile patients, with or without endometriosis, submitted to induction of ovulation for assisted reproduction procedures. METHODS: infertile patients aged 20 to 38 years old were selected prospectively and consecutively and divided into Endometriosis Group (17 patients with pelvic endometriosis) and Control Group (19 patients with previous tubal ligation or with male factor). Blood samples were collected on: D1 (before the beginning of the use of gonadotrophins), D2 (day of human chorionic gonadotrofin application) and D3 (day of oocyte retrieval). On D3, follicular fluid samples free from blood contamination were also collected and stored. LP was assessed for malondialdehyde (MDA) quantification by spectrophotometry, and antioxidant status by measurement of vitamin E by HLPC. RESULTS: on D1, no significant difference in LP was observed between groups. However, vitamin E levels were significantly higher in the Control Group. On D2, LP levels were significantly higher in the Endometriosis Group compared to Control and vitamin E levels continued to be significantly higher in the Control Group. On D3, there was no significant difference in both serum and follicular fluid levels of LP or vitamin E between groups. However, on D3, vitamin E levels were found to be significantly higher in serum than in follicular fluid in both groups, whereas MDA levels were significantly lower in follicular fluid than in serum only in the Control Group. CONCLUSION: before the beginning of the induction of ovulation, a significant decrease in antioxidant status was observed in patients with endometriosis, perhaps because antioxidants are consumed during oxidation reactions. After the induction of ovulation with exogenous gonadotrophins, the group of patients with endometriosis presented not only increased lipid peroxidation compared to Control, but also maintained a lower antioxidant status than the Control Group. However, on the day of oocyte retrieval, both serum LP potential and the levels of vitamin E were found to be similar in both groups.

Purpose: to present a profile of endometriosis, stages and results of treatment among the patients seen in our Service. Methods: the medical records of 155 patients with endometriosis treated during the period from 1991 to 1996 according to a preestablished protocol were examined. Results: mean patient age was 31 years, most patients were white, with regular menstrual cycles. The most frequently observed symptoms were dysmenorrhea, pelvic pain and infertility and were mild in most of the cases. The diagnostic methods utilized were laparoscopy or echography. There was agreement between echography and laparoscopy in 96% of cases. Laparotomy was required in 28% of cases for diagnostic elucidation and/or treatment. Endometrioma was detected in 37% of the cases and endometriosis was confirmed in only 74% of the biopsies from the lesion by anatomopathological examination. There was a significant improvement with clinical treatment regardless of the drug used, with improved symptoms in approximately 50% of the patients. Assisted fertilization was performed in 34 patients, consisting of in vitro fertilization (IVF) for 80% of them, with a 27% pregnancy/transfer rate. Conclusions: the diagnostic method of choice should be laparoscopy, although echography presented a high rate of agreement. Anatomopathological examination of the lesions should be used as an adjuvant method in the diagnosis since it is not confirmatory in all of the cases. Clinical treatment with assisted reproductive technologies is a good therapeutic option, especially with the use of IVF.

Chronic pelvic pain is a debilitating and highly prevalent disease with a major impact on quality of life and work productivity, beyond significant costs to health services. The dilemma of managing patients with chronic pelvic pain continues to frustrate physicians confronted with these complaints, in part because its pathophysiology is poorly understood. Consequently, its treatment is often unsatisfactory and limited to temporary symptom relief. In the present revision, we discuss the adequate management of chronic pelvic pain. We point out that a comprehensive medical history and physical examination should include special attention to gastrointestinal, urological, gynecological, muscle-skeletal, neurological, psychiatric, and endocrine systems. Thus, a multidisciplinary approach is recommended. Additionally, we emphasize that, although useful, specific surgical procedures, such as laparoscopy, should be indicated only to selected patients, mainly after excluding irritable bowel syndrome and pain of myofascial origin.

PURPOSE: literature reports show that there are no conclusive data about the association between endometriosis and the concentrations of hormones involved in the control of reproduction. Thus, the present study was undertaken to determine FSH, LH, estradiol (E), progesterone (P), and histamine (Hi) concentrations in serum, peritoneal fluid and follicular fluid of women with and without endometriosis. METHODS: the extent of the disease was staged according to the revised American Fertility Society classification (1997). For the collection of serum and peritoneal fluid, 28 women with endometriosis undergoing diagnostic laparoscopy were selected (18 infertile women with endometriosis I-II and ten infertile women with endometriosis III-IV). For the control group, 21 fertile women undergoing laparoscopy for tubal sterilization were selected. Follicular fluid was obtained from 39 infertile women undergoing in vitro fertilization (21 women with endometriosis and 18 women without endometriosis). RESULTS: FSH and LH levels in serum, peritoneal fluid and follicular fluid did not differ significantly between groups. On the other hand, E and P concentrations in the peritoneal fluid were significantly lower in infertile women with endometriosis (E: 154.2±15.3 for stages I-II and 89.3 ng/mL±9.8 ng/mL for stages III-IV; P: 11.2±1.5 for stages I-II and 7.6 ng/mL±0.8 for stages III-IV) in comparison with control women (E: 289.1 ng/mL±30.1; P: 32.8±4.1 ng/mL) (Kruskal-Wallis/Dunn tests; p<0.05). In serum, estradiol and progesterone concentrations followed the same pattern. In the follicular fluid, E and Hi concentrations were significantly lower in women with endometriosis (E: 97.4±11.1 pg/mL; Hi: 6.6±0.9 ng/mL) in comparison to women without endometriosis (E: 237.5±28.5 pg/mL; Hi: 13.8±1.3 ng/mL) (Student t-test; p<0.05), while progesterone levels revealed no significant difference between groups. CONCLUSIONS: our results indicate ovary dysfunction in women with endometriosis, with reduction on E, P and Hi concentrations, which may contribute to the subfertility often associated with the disease.

PURPOSE: to verify the effects of intrauterine levonorgestrel device (IUD) in women with adenomyosis, with implantation failure in previous in vitro fertilization (IVF) cycles. METHODS: eighty infertile women with ages up to 38 years, who had adenomyosis diagnosed by ultrasonography and MRI were selected. All the women presented antecedents of one or more tormer IVF attempts without success due to implantation failure. The women were subdivided into IUD Group, composed of 40 women with an IUD that released 20 µg of levonorgestrel/day during six months, preceding a new IVF cycle, and IVF Group, also composed of 40 women, who were directly submitted to a new IVF cycle without previous adenomyosis treatment. In the IUD Group the uterine volume, thickness and hypersignal foci of the junctional zone were assessed before and after treatment, as well as the pregnancy rates in the new IVF cycle, compared to the data obtained with the IVF Group. Statistical analyses were performed adopting the significance level of 5% (p<0,05), using the Mann-Whitney and Sudent's t tests. RESULTS: after treatment, there was a reduction of 77.7% in the cases of focal adenomyosis, in addition to a significant reduction of the uterine volume and of the mean thickness of the junctional zone from 128.8 to 93.6 ml and from 12.3 to 11.3 mm, respectively. In the IUD Group, pregnancy rate reached 30%, which was higher than, but not significantly different from that of the IVF group, which was 17.5%. CONCLUSION: the use of an IUD with levonorgestrel may be administered prior to IVF cycles in patients with adenomyosis who suffered previous implantation failure.
