ALCAZAR, Juan Luis et al. Clinical relevance of the pedicle sign in diagnosing of the endometrial polyp. Salud(i)ciencia [online]. 2017, vol.22, n.6, pp.539-544. ISSN 1667-8682.

Abstract Objective: To evaluate the diagnostic performance of vascular pedicle sign detected by color Doppler/power ultrasound for the diagnosis of endometrial polyp. Method: A systematic review and meta-analysis was performed. An electronic search (Pubmed) was conducted using the following terms: "endometrial polyp", "Doppler", "ultrasound" (MeSH), and "pedicle sign". Criteria for inclusion were as follows: prospective or retrospective cohort studies; studies of women with endometrial organic pathology and women with endometrial polyps; studies to evaluate the diagnostic test using color Doppler ultrasound/power for the diagnosis of endometrial polyp, and studies using pathological diagnosis as the gold standard. The period covered was January 2003 to May 2015. All analyses were performed using the MIDAS and METANDI module STATA version 12.0 for Windows (Stata Corporation, College Station, TX, USA). A value of p < 0.05 was considered statistically significant. Results: A total of 629 papers were identified, of which 623 were excluded, including 6 studies in the meta-analysis. These studies included 1237 women and 362 endometrial polyps (29.3% prevalence). The sensitivity, specificity, LR and LR- for the sign of the pedicle were 77% (95% CI, 53%-91%), 95% (95% CI, 87%-98%), 16.0 (95% CI, 7.1-35.9) and 0.24 (95% CI, 0.11 to 0.54), respectively. Significant heterogeneity was detected in studies. Conclusion: The sign of the pedicle provides acceptable performance for diagnosis of endometrial polyp.
