TVUS had better sensitivity, specificity, PPV, NPV and accuracy in cases of deep retrocervical and rectosigmoid endometriosis when compared with MRI and digital vaginal examination, confirming that it is an important preoperative examination for the definition of surgical strategies.

Both, the LNG-IUS and the GnRH-analogue were effective in the treatment of CPP-associated endometriosis, although no differences were observed between the two treatments. Among the additional advantages of the LNG-IUS is the fact that it does not provoke hypoestrogenism and that it requires only one medical intervention for its introduction every 5 years. This device could therefore become the treatment of choice for CPP-associated endometriosis in women who do not wish to conceive.

background: Successful surgical treatment of deep bowel endometriosis depends on obtaining detailed information about the lesions, prior to the procedure. The objective of this study was to determine the capability of transvaginal ultrasonography with bowel preparation (TVUS-BP) to predict the presence of one or more rectosigmoid nodules and the deepest bowel layer affected by the disease. results: With respect to bowel nodule detection and presence of at least two rectosigmoid lesions, TVUS-BP had a sensitivity of 97 and 81%, specificity 100 and 99%, positive predictive value (PPV) 100 and 93% and negative predictive value (NPV) 98 and 96%, respectively. Regarding diagnosis of infiltration of the submucosal/mucosal layer, TVUS-BP had a sensitivity of 83%, specificity 94%, PPV 77%, NPV 96%.conclusions: These findings show that TVUS-BP is an adequate exam for evaluating the presence of one or more rectosigmoid nodules and the deepest layer affected in deep infiltrating bowel endometriosis, confirming the importance of this technique for defining the most appropriate surgical strategy to be implemented.

The aim of this study was to evaluate CA 125 II, C-reactive protein (CRP) and serum amyloid A (SAA) and anticardiolipin antibody (aCL) concentrations for the diagnosis of pelvic endometriosis. The study population consisted of 15 women without endometriosis, as confirmed by laparoscopy (group A), and 35 patients with pelvic endometriosis diagnosed by laparoscopy or laparotomy (group B). Group B patients were divided into those at stages I and II of the disease (BI/II) and those at stages III and IV (BIII/IV). Blood samples were obtained twice during the menstrual cycle: on day 1, 2 or 3 of the cycle and on day 8, 9 or 10 of the cycle. CA 125 II and CRP concentrations were higher in group III/IV patients compared with healthy controls, mainly during the first 3 days of the menstrual cycle; SAA concentrations were also higher in this group of patients compared with healthy controls, but only during the first 3 days of the menstrual cycle. Immunoglobulin (Ig) M aCL concentrations were higher in all patients with endometriosis compared with healthy controls, mainly during the first 3 days of the menstrual cycle. It is concluded that these determinations may contribute to the diagnosis and the indication of treatment for pelvic endometriosis. Determination of CA 125 II concentrations at the beginning of the menstrual cycle may aid the diagnosis of stage III and IV endometriosis. IgM aCL appears to be associated with the presence of all stages of the disease, while SAA values are elevated in severe situations. Measurement of these molecules may therefore provide a valuable tool in the diagnosis and management of endometriosis.
