Accuracy of cervicovaginal fetal fibronectin test in predicting risk of spontaneous preterm birth: systematic review.

OBJECTIVE: To determine the accuracy with which a cervicovaginal fetal fibronectin test predicts spontaneous preterm birth in women with or without symptoms of preterm labour. DESIGN: Systematic quantitative review of studies of test accuracy. DATA SOURCES: Medline, Embase, PASCAL, Biosis, Cochrane Library, Medion, National Research Register, SCISEARCH, conference papers, manual searching of bibliographies of known primary and review articles, and contact with experts and manufacturer. STUDY SELECTION: Two reviewers independently selected and extracted data on study characteristics, quality, and accuracy. DATA EXTRACTION: Accuracy data were used to form 2x2 contingency tables with spontaneous preterm birth before 34 and 37 weeks' gestation and birth within 7-10 days of testing (for symptomatic pregnant women) as reference standards. Data were pooled to produce summary receiver operating characteristic curves and summary likelihood ratios for positive and negative test results. DATA SYNTHESIS: 64 primary articles were identified, consisting of 28 studies in asymptomatic women and 40 in symptomatic women, with a total of 26 876 women. Among asymptomatic women the best summary likelihood ratio for positive results was 4.01 (95% confidence interval 2.93 to 5.49) for predicting birth before 34 weeks' gestation, with corresponding summary likelihood ratio for negative results of 0.78 (0.72 to 0.84). Among symptomatic women the best summary likelihood ratio for positive results was 5.42 (4.36 to 6.74) for predicting birth within 7-10 days of testing, with corresponding ratio for negative results of 0.25 (0.20 to 0.31). CONCLUSION: Cervicovaginal fetal fibronectin test is most accurate in predicting spontaneous preterm birth within 7-10 days of testing among women with symptoms of threatened preterm birth before advanced cervical dilatation.

Current practice for the treatment of benign intrauterine polyps: a national questionnaire survey of consultant gynaecologists in UK.

OBJECTIVE: To determine current practice regarding removal of endometrial polyps. STUDY DESIGN: A self-administered questionnaire to all 1509 UK consultant gynaecologists to enquire about their current practice and potential willingness to participate in a randomised trial. RESULTS: Treatment methods varied considerably. Inpatient polypectomy was used by 91% and the favoured method was blind removal of polyp following hysteroscopic localisation (53%). Direct hysteroscopic polypectomy was more commonly performed by 46% members of endoscopic societies compared to 33% of non-members. Outpatient polypectomy was performed by 19% of users of outpatient diagnostic hysteroscopy compared to 2.5% of non-users. One-third of respondents were willing to enter patients into a randomised controlled trial to determine the optimal intrauterine polyp removal technique. CONCLUSION: Opinion regarding the relative roles of inpatient or outpatient, and blind or hysteroscopic methods, is divided and a randomised trial comparing the efficacy and safety of these methods is practicable.

Hysteroscopic treatment of symptomatic submucous fibroids using a bipolar intrauterine system: a feasibility study.

OBJECTIVE: To determine the feasibility (safety, potential efficacy and cost effectiveness) of a miniature endoscopic bipolar electrosurgical intrauterine system in the treatment of symptomatic submucous fibroids. STUDY DESIGN: A total of 37 women with symptomatic submucous fibroids were identified on outpatient hysteroscopy. All underwent hysteroscopic excision or ablation using a bipolar intrauterine system (Versapoint). The main outcomes measures were change in uterine bleeding symptoms measured on a continuous and ordinal scale, patient satisfaction, time of work and use of health service resources at 6 months following treatment. RESULTS: 36/37 (97%) women returned completed outcome questionnaires. The mean amount of abnormal uterine bleeding was reduced at 6 months compared to immediately prior to treatment (P=0.0001). Improvement in bleeding symptoms was reported by 28/36 (78%) women and satisfaction with treatment by 33/36 (92%) women. All procedures were successfully completed, there were no serious operative complications and at 6 months no repeat hysteroscopic procedures were necessary. The mean cost of diagnosis and treatment of submucous fibroids using an endoscopic bipolar intrauterine system was 40% cheaper at 6 months follow-up than a hysterectomy or open myomectomy ( pound 1266 versus pound 2123). CONCLUSION: Hysteroscopic treatment of symptomatic submucous fibroids appears to be safe, efficacious and cost effective. It seems feasible to launch a randomised controlled trial to confirm these provisional results in both the short and longer term.

Evaluation of outpatient hysteroscopy and ultrasonography in the diagnosis of endometrial disease.

OBJECTIVE: To develop a multivariable approach to determine the added value of tests in routine practice where some diagnostic information is already available from clinical history. METHODS: Multivariable logistic regression models were built in a stepwise fashion, considering the clinical sequence used in the rapid access ambulatory diagnosis clinic (clinical history followed by transvaginal ultrasonography and hysteroscopy). The reference standard for confirmation of diagnosis was endometrial biopsy. The diagnostic accuracy of the models was determined by the area under the receiver operating characteristic curve. RESULTS: The area under the receiver operating characteristic curve for the model including historical features alone was 0.78. When hysteroscopy and ultrasonography were each added to the model, it increased to 0.81 (P =.008 for improvement) and 0.82 (P =.02 for improvement), respectively. CONCLUSION: The type of stepwise analysis we have developed is crucial in facilitating meaningful clinical interpretation about the value of diagnostic technology. Our finding that hysteroscopy or ultrasonography marginally but significantly increased the prediction of serious endometrial pathology above that predicted from patient history alone needs validation in an independent data set. The use of this approach is recommended when evaluating strategies for diagnosis.

Ultrasonographic endometrial thickness for diagnosing endometrial pathology in women with postmenopausal bleeding: a meta-analysis.

Our aim was to determine the diagnostic accuracy of endometrial thickness measurement by pelvic ultrasonography for predicting endometrial carcinoma and disease (hyperplasia and/or carcinoma) during an investigation of postmenopausal bleeding. We performed a systematic quantitative review of the available published literature, which consisted of online searching the MEDLINE and EMBASE databases (1966-2000) coupled with scanning of bibliography of known primary and review articles. The selection of studies, assessment of study quality, and extraction of data were performed in duplicate under masked conditions. Included in the analyses were 57 studies with 9031 patients. Accuracy data were summarized using likelihood ratios for various cut-off levels of abnormal endometrial thickness. The commonest cut-offs were 4 mm (9 studies) and 5 mm (21 studies), measuring both endometrial layers. None of the nine studies using the < or = 4 mm cut-off level were of good quality. Only four studies (out of the 21) used the < or = 5 mm cut-off level, which employed the best-quality criteria. Using the pooled estimates from these four studies only, a positive test result raised the probability of carcinoma from 14.0% (95% CI 13.3-14.7) to 31.3% (95% CI 26.1-36.3), while a negative test reduced it to 2.5% (95% CI 0.9-6.4). In conclusion, ultrasound measurement of endometrial thickness alone, using the best-quality studies cannot be used to accurately rule. However, a negative result at < or = 5 mm cut-off level measuring both endometrial layers in the presence of endometrial pathology rules out endometrial pathology with good certainty.

Accuracy of outpatient endometrial biopsy in the diagnosis of endometrial cancer: a systematic quantitative review.

OBJECTIVE: To determine the accuracy of outpatient endometrial biopsy in diagnosing endometrial cancer in women with abnormal uterine bleeding. DESIGN: A systematic quantitative review of published research. METHODS: Studies were selected if accuracy of outpatient endometrial biopsy was estimated compared with a reference standard. Diagnostic accuracy was determined by pooled likelihood ratios for positive and negative test results. There were 1013 subjects in 13 diagnostic evaluations reported in 11 primary studies. RESULTS: A positive test result on outpatient biopsy diagnosed endometrial cancer with a pooled likelihood ratio of 66.48 (95% CI 30.04-147.13) while a negative test result had a pooled likelihood ratio of 0.14 (95% CI 0.08-0.27). The post test probability of endometrial cancer was 81.7% (95% CI 59.7%-92.9%) for a positive test and 0.9% (95% CI 0.4%-2.4%) for a negative test. CONCLUSION: Outpatient endometrial biopsy has a high overall accuracy in diagnosing endometrial cancer when an adequate specimen is obtained. A positive test result is more accurate for ruling in disease than a negative test result is for ruling it out. Therefore, in cases of abnormal uterine bleeding where symptoms persist despite negative biopsy, further evaluation will be warranted.
