Concordance Between Hysteroscopy, Ultrasound, and Pathological Findings in Perimenopausal Patients with Abnormal Uterine Bleeding

OBJECTIVE: To determine the concordance between hysteroscopic, ultrasonographic, and pathological findings, estimating the sensitivity and specificity of hysteroscopy and ultrasound with the histopathological study in perimenopausal patients diagnosed with abnormal uterine bleeding during the period February 2024-November 2024 at the Veracruz High Specialty Hospital MATERIAL AND METHODS: Records of perimenopausal patients with abnormal uterine bleeding who underwent an ultrasound and hysteroscopic evaluation at the Veracruz Regional High Specialty Hospital were reviewed. The Kappa test was applied for concordance of qualitative variables, the sensitivity and specificity of hysteroscopy and ultrasound with the histopathological study was estimated. Finally, the results will be grouped into pie charts and bar graphs. RESULTS: we recorded data of 70 patients and we analiced a sensitivity of 0.93 (95%CI:) and specificity of 0.94 (95%CI:) were recorded for hysteroscopy, for ultrasonography a sensitivity of 0.93 (95%CI) and specificity of 0.93 (95%CI:). The concordance between histopathology and hysteroscopy was 0.8573724387 (KAPPA VALUE) (95%CI 1- 0.624) CONCLUSIONS: Hysteroscopy in the diagnosis of the causes of abnormal uterine bleeding in perimenopausal women showed a remarkable concordance with the histopathological findings. The sensitivity and specificity values highlight hysteroscopy as a reliable and superior method compared to ultrasonography. The combination of both techniques can improve the diagnosis and management of these patients.
