A total of 88 Fallopian tubes from 44 patients was examined with hysterosalpingo contrast sonography (HyCoSy), hysterosalpingogram (HSG), and laparoscopic chromopertubation (LC) in order to assess their relative accuracy for measuring tubal patency. HyCoSy was done by transvaginal ultrasound and the contrast was SH U 454 (Echovist). The flow of multiple fractions of the contrast medium through each Fallopian tube was observed in real time in appropriate imaging planes by means of a transvaginal probe. Compared with laparoscopic results, we found a sensitivity of 85.2%, a specificity of 85.2%, a positive predictive value (PPV) of 71.9%, a negative predictive value (NPV) of 92.9% and concordance (HyCoSy/LC) of 85.2%, while the corresponding values for HSG were sensitivity = 85.2%, specificity = 83.6%, PPV = 69.7%, NPV = 92.7% and concordance (HSG/LC) of 84.1%. Compared with HSG results, HyCoSy obtained a co-positivity of 66.7%, a co-negativity of 81.8% and a concordance of 76.1%. In conclusion, HyCoSy with SH U 454 proved to be a reliable and safe modality for evaluating tubal patency; it is suitable as an outpatient diagnostic procedure to be used before more invasive procedures.
Objective-To examine the impact of a recent surgery on development of endometriosis-related adhesions in a chimeric model and to determine the therapeutic efficacy of pioglitazone (PIO).Design-Human endometrial biopsies were maintained in estradiol (E) with or without PIO for 24 hrs prior to intraperitoneal injection into immunocompromised mice at multiple timepoints following peritoneal surgery. The presence and extent of adhesions was examined in animals relative to the initial establishment of experimental endometriosis.
Setting-Medical School Research CenterPatients-Endometrial biopsies for experimental studies described herein were provided by normally cycling women without a medical history indicative of endometriosis or adhesions.
Interventions-NoneMain Outcome Measure-Examination of the development of endometriosis-related adhesions in an experimental model.Results-Without therapeutic intervention, injection of E-treated human endometrial tissue into mice near the time of peritoneal surgery resulted in multiple adhesions and extensive endometriotic-like disease. In contrast, PIO treatment reduced adhesive disease and experimental endometriosis related to surgical injury.Conclusions-The presence of human endometrial tissue fragments in the peritoneal cavity of mice with a recent surgical injury promoted development of both adhesive disease and
Chronic endometritis has been related to infertility and recurrent abortion. It is usually asymptomatic, and the diagnosis is rarely clinically suspected. We performed a prospective study to evaluate both the role of diagnostic hysteroscopy in the detection of chronic endometritis in infertile patients and Chlamydia trachomatis is a potential etiologic factor. Fifty consecutive patients who sought treatment for infertility in a tertiary academic hospital were submitted to diagnostic hysteroscopy and an endometrial biopsy for histopathological study and for diagnosis of C. trachomatis by polymerase chain reaction. The patients’ mean age was 33.7 ± (SD) 5.4 years, and the duration of the couples’ infertility ranged from 1 to 18 years. The overall prevalence of chronic endometritis was 12% (6 patients). Among all patients, no cases of chlamydial infection were detected by polymerase chain reaction. In the detection of chronic endometritis, with 95% confidence intervals, the hysteroscopy sensitivity was 16.7% (range 0.9–63,5%), the specificity was 93.2% (range 80.3–98.2%), the positive predictive value was 25% (range 1.3–78.1%), and the negative predictive value was 89.1% (range 65.6–95.9%). These data suggest that hysteroscopy is not useful in the screening for chronic endometritis in asymptomatic infertile women. Further studies are needed to establish the etiology of endometritis in infertile patients.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
