| description | Objective: The aim of this systematic review and meta-analysis was to evaluate the diagnostic accuracy of the sliding sign on transvaginal ultrasound (TVS) in detecting pouch of Douglas obliteration and bowel involvement in patients with suspected endometriosis, using laparoscopy as the reference standard.
Methods: A search for studies evaluating the role of the sliding sign in the assessment of pouch of Douglas obliteration and/or bowel involvement using laparoscopy as the reference standard published from January 2000 to October 2021 was performed in PubMed/MEDLINE, Web of Science, CINAHL, The Cochrane Library, ClinicalTrials.gov and SCOPUS databases. The Quality Assessment of Diagnostic Accuracy Studies-2 (QUADAS-2) was used to evaluate the quality of the studies. Analyses were performed using MIDAS and METANDI commands in STATA.
Results: A total of 334 citations were identified. Eight studies were included in the analysis, resulting in 938 and 963 patients available for analysis of the diagnostic accuracy of the sliding sign for pouch of Douglas obliteration and bowel involvement, respectively. The mean prevalence of pouch of Douglas obliteration was 37% and the mean prevalence of bowel involvement was 23%. The pooled estimated sensitivity, specificity, positive likelihood ratio, negative likelihood ratio and diagnostic odds ratio of the sliding sign on TVS for detecting pouch of Douglas obliteration were 88% (95% CI, 81-93%), 94% (95% CI, 91-96%), 15.3 (95% CI, 10.2-22.9), 0.12 (95% CI, 0.07-0.21) and 123 (95% CI, 62-244), respectively. The heterogeneity was moderate for sensitivity and low for specificity for detecting pouch of Douglas obliteration. The pooled estimated sensitivity, specificity, positive likelihood ratio, negative likelihood ratio and diagnostic odds ratio of the sliding sign on TVS for detecting bowel involvement were 81% (95% CI, 64-91%), 95% (95% CI, 91-97%), 16.0 (95% CI, 9.0-28.6), 0.20 (95% CI, 0.10-0.40) and 81 (95% CI, 34-191), respectively. The heterogeneity for the meta-analysis of diagnostic accuracy for bowel involvement was high.
Conclusion: The sliding sign on TVS has good diagnostic performance for predicting pouch of Douglas obliteration and bowel involvement in women with suspected endometriosis. © 2022 The Authors.

El objetivo de esta revisión sistemática y metaanálisis fue evaluar la precisión diagnóstica del signo deslizante en la ecografía transvaginal (ETV) para detectar la obliteración del fondo de saco de Douglas y la afectación intestinal en pacientes con sospecha de endometriosis, utilizando la laparoscopia como estándar de referencia. Métodos. Se realizó una búsqueda de estudios que hubieran evaluado la función del signo deslizante en la valoración de la obliteración del fondo de saco de Douglas y/o la afectación intestinal utilizando la laparoscopia como estándar de referencia, publicados desde enero de 2000 hasta octubre de 2021 en las bases de datos PubMed/MEDLINE, Webof Science, CINAHL, The Cochrane Library, ClinicalTrials.gov y SCOPUS. Para evaluar la calidad de los estudios se utilizó la herramienta de Evaluación de Calidad de los Estudios de Precisión Diagnóstica-2 (QUADAS-2, por sus siglas en inglés) Los análisis se realizaron mediante los comandos MIDAS y METANDI de STATA. Resultados .Se identificaron un total de 334 citas. En el análisis se incluyeron ocho estudios, lo que dio como resultado938 y 963 pacientes disponibles para el análisis de la precisión diagnóstica del signo deslizante para la obliteración del fondo de saco de Douglas y la afectación intestinal, respectivamente. La prevalencia media de la obliteración del fondo de saco de Douglas fue del 37% y la prevalencia media de la afectación intestinal fue del 23%. La estimación combinada de la sensibilidad, especificidad, cociente de verosimilitud positivo, cociente de verosimilitud negativo y razón de momios del diagnóstico del signo deslizante en la ETV para detectar la obliteración del fondo de saco de Douglas fue del 88% (IC 95%, 81 – 93%), 94% (IC 95%, 91 – 96%), 15,3 (IC 95%, 10,2 – 22,9), 0,12 (IC 95%, 0,07 – 0,21)y 123 (IC 95%, 62 – 244), respectivamente. La heterogeneidad fue moderada en cuanto a la sensibilidad y baja en cuanto a la especificidad para detectar la obliteración del fondo de saco de Douglas. La estimación combinada de la sensibilidad, especificidad, cociente de verosimilitud positivo, cociente de verosimilitud negativo y razón de momios del diagnóstico del signo deslizante en la ETV para detectar la afectación intestinal fue del 81% (IC 95%, 64 – 91%), 95%(IC 95%, 91 – 97%), 16,0 (IC 95%, 9,0 – 28,6), 0,20 (IC 95%, 0,10 – 0,40) y 81 (IC 95%, 34 – 191), respectivamente .La heterogeneidad del meta análisis de la precisión diagnóstica de la afectación intestinal fue alta. Conclusiones. El signo deslizante en la ETV tiene un buen rendimiento diagnóstico para predecir la obliteración del fondo de saco de Douglas y la afectación intestinal en mujeres con sospecha de endometriosis.©2022 The Authors.
