Despite problems in interpretation of data, the effect of medical treatment in terms of pain relief in women with rectovaginal endometriosis appear substantial.

The aim of this work was to test and compare the accuracy of five different morphological scoring systems to identify malignant ovarian masses in a prospective multicenter study. Four of the systems had previously been reported by Granberg, Sassone, De Priest and Lerner and the fifth is newly developed. A total of 330 ovarian neoplasms were collected in three different centers, which adopted the same diagnostic procedures. Of these, 261 masses were benign (mean diameter 50 +/- 26 mm) and 69 were malignant (mean diameter 69 +/- 33 mm) (prevalence 21%). The area under the receiver operating characteristic (ROC) curve for the multicenter score was 0.84. This was significantly better than the areas of the other four scores which ranged from 0.72 to 0.75. The cut-off levels derived from the five ROC curves achieved a sensitivity that ranged from 74% (Sassone score) to 88% (De Priest score > or = 5), and a specificity from 40% (De Priest) to 67% (multicenter); the highest positive predictive value was 41% (multicenter). With a cut-off level of 9, the accuracy of the multicenter score was significantly better than the scores of Granberg and De Priest (McNemar's test p < 0.0001). Similar results were obtained in 207 ovarian masses of < or = 5 cm in mean diameter, and when 19 borderline and 11 stage 1 cancers only were considered. For the clinical purposes of a screening test we also checked a possible cut-off level of > or = 8, which increased the sensitivity to 93% with a drop of specificity to 56%. With the use of the same criteria for the scores of the different authors, the following values were obtained for sensitivity: 96%, 81%, 93% and 90%; and for specificity: 23%, 56%, 28% and 49%. The multicenter score performed well at distinguishing malignant from benign lesions, and was better than the other four traditional scores, for both large and small masses. This was mainly due to the introduction of two criteria that allowed correction for typical dermoids and endohemorrhagic corpora lutea. A completely reliable differentiation of benign from malignant masses cannot be obtained by sonographic imaging alone.

The risk of pregnancy and neonatal complications in women with endometriosis and adenomyosis is debatable. A literature review looking at rates, presentation, and management of spontaneous hemoperitoneum, enlargement, abscess, and rupture of an endometrioma, uterine rupture, and bowel perforation in pregnant women with endometriosis was conducted. Moreover, studies addressing differences in early pregnancy (miscarriage), late pregnancy (gestational diabetes mellitus, preeclampsia, prematurity, placenta previa, placental abruption, cesarean section, hemorrhages) and neonatal outcomes (weight at birth) between endometriosis and adenomyosis patients versus control subjects were reviewed. The overall prevalence of endometriosis-related spontaneous hemoperitoneum in pregnancy is estimated to be ∼0.4%. Only four cases of endometrioma rupture in pregnancy have been reported. Although during pregnancy there is no way to anticipate the onset of complications from preexisting endometriosis, it is important, when a specific abdominal pain occurs, to suspect rare but potentially life-threating events. Population-based studies suggest a possible association of endometriosis with preterm birth and placenta previa. Limits of the published studies are noted and discussed.

Deep endometriosis, occurring approximately in 1% of women of reproductive age, represents the most severe form of endometriosis. It causes severe pain in the vast majority of affected women and it can affect the bowel and the urinary tract. Hormonal treatment of deep endometriosis with progestins, such as norethindrone acetate or dienogest, or estroprogestins is effective in relieving pain in more than 90% of women at one year follow up. Progestins and estroprogestins can be safely administered in the long-term, may be not expensive and are usually well tolerated. Therefore, they should represent the first-line treatment of deep endometriosis associated pain in women not seeking natural conception. However, hormonal treatment is ineffective or not tolerated in about 30% of women, the most common side effects being erratic bleeding, weight gain, decreased libido and headache. Surgical excision of deep endometriosis is mandatory in presence of symptomatic bowel stenosis, ureteral stenosis with secondary hydronephrosis, and when hormonal treatments fail. Surgical treatment is similarly effective as compared to hormonal treatment in relieving dismenorhea, dyspareunia and dyschezia at one year follow up in more than 90% of women with deep endometriosis. Surgical removal of the nodules may require resection of the bowel, ureter or bladder, with possible severe complications such as rectovaginal or ureterovaginal fistula and anastomotic leakage. A thorough counsel with the patient is necessary in order to pursue a therapeutic plan centered not on the endometriotic lesions, but on the patient's symptoms, priorities and expectations.
