Biopsia guiada por ecografía para el diagnóstico de masas ováricas. Revisión sistemática / Ecography guided biopsy for the diagnosis of ovarian masses. Systematic review

El diagnóstico definitivo del cáncer de ovario precisa de confirmación histológica. En determinadas situaciones, para evitar la morbilidad de la resección quirúrgica, es posible hacer una biopsia guiada por ecografía para obtener el diagnóstico anatomopatológico. El objetivo de esta revisión sistemática fue evaluar la adecuación, fiabilidad, precisión y perfil de seguridad de la biopsia guiada por ecografía de masas ováricas. Siguiendo el modelo PRISMA 2020, se hizo una búsqueda bibliográfica en PubMed, Embase y Scopus y se recopilaron un total de 10.245 artículos, de los cuales 24 fueron finalmente incluidos. Los trabajos incluían de forma mayoritaria pacientes con tumores inoperables avanzados, pobre performance status y otros factores de mal pronóstico, con masas de contenido sólido y márgenes irregulares, generalmente accesibles por vía transvaginal. En la mayoría de los artículos las pacientes presentaban historia previa de malignidad o tumores inoperables en estadios avanzados. Las masas ováricas biopsiables se definían en la ecografía como malignas o potencialmente malignas, con la presencia destacada de un componente sólido o mixto con márgenes irregulares o heterogéneos. La técnica más utilizada en los estudios incluidos fue la biopsia con aguja gruesa o tru-cut, con altos valores de adecuación, fiabilidad, precisión y rendimiento, así como un buen perfil de seguridad y bajas tasas de complicaciones. En conclusión, la biopsia con aguja gruesa de las masas anexiales guiada por ecografía, en pacientes subsidiarios de tratamiento neoadyuvante, es una técnica con altas tasas de adecuación, fiabilidad, precisión y buen perfil de seguridad.(AU)

The definitive diagnosis of ovarian cancer requires histological confirmation. In certain situations, to avoid the morbidity of surgical resection, it is possible to perform an ultrasound-guided biopsy to obtain the pathological diagnosis. The aim of this systematic review was to assess the adequacy, reliability, accuracy, and safety profile of ultrasound-guided biopsy of ovarian masses. Following the PRISMA 2020 model, a bibliographic search was carried out in PubMed, Embase and Scopus, collecting a total of 10,245 articles, of which 24 were finally included. The studies mainly included patients with advanced inoperable tumors, poor performance status and other poor prognostic factors, with masses of solid content and irregular margins, generally accessible through the transvaginal route. In most of the articles, the patients had a previous history of malignancy or had inoperable tumors in advanced stages. Biopsiable ovarian masses were defined ultrasonographically as malignant or potentially malignant, mainly highlighting the presence of a solid or mixed component and irregular or heterogeneous margins. The most widely used technique in the included studies was core needle or tru-cut biopsy, presenting high values of adequacy, reliability, precision and performance, as well as a good safety profile with low complication rates. In conclusion, ultrasound-guided core needle biopsy of adnexal masses in patients eligible for neoadjuvant treatment is a technique with high adequacy, reliability, and precision rates, as well as a good safety profile.(AU)

Contrast-enhanced ultrasonography to guide diagnostic and therapeutic interventional procedures.

Although not necessary for the vast majority of ultrasound-guided procedures, intravenous contrast agents can be useful for procedures aimed at lesions that require contrast enhancement to be seen on ultrasonography. Using contrast-enhanced ultrasonography to guide procedures has two drawbacks: first, because enhancement from ultrasound contrast agents is short lived, it is often necessary to plan several injections; second, because the needle is poorly seen on contrast-enhanced ultrasonography, a dual image display format is necessary. Contrast-enhanced ultrasonography can be used for planning and monitoring diagnostic and therapeutic procedures, for guiding the procedures, and for follow-up. Using contrast-enhanced ultrasonography enables better results in both types of procedures; moreover, it can be used within cavities.

Ecografía con contraste en procedimientos ecoguiados / Contrast-enhanced ultrasonography to guide diagnostic and therapeutic interventional procedures

Aunque el contraste intravenoso no es necesario en la inmensa mayoría de los procedimientos realizados con guía ecográfica, su uso puede permitir realizar procedimientos en aquellas lesiones que solo se visualizan con ecografía con contraste. Los problemas que tiene son dos: el tiempo limitado del realce producido por el contraste, que requiere con frecuencia planificar varias inyecciones, y la mala visualización de la aguja, que requiere el uso de doble ventana de visualización. Puede ser usada en la planificación y el control de los procedimientos diagnósticos y terapéuticos, tanto en la guía del procedimiento, para monitorizar el alcance del tratamiento, como en los controles posteriores. Su uso permite mejorar los resultados de ambos tipos de procedimientos. Puede ser usada también intracavitariamente.(AU)

Estudio comparativo de costo efectividad de la biopsia quirúrgica guiada por estereotaxia con arpón vs biopsia por estereotaxia asistida al vacío para la evaluación de microcalcificaciones sugestivas de malignidad mamaria / Comparative study of cost-effectiveness of surgical biopsy guided by stereotaxy with harpoon vs Vacuum-assisted stereotactic breast biopsy for the evaluation of microcalcifications suggestive of mammary malignancy

La biopsia quirúrgica guiada por estereotaxia de microcalcificaciones mamarias por mucho tiempo es considerada el estándar de oro para determinar la malignidad de las microcalcificaciones. Los objetivos son realizar un análisis de costos directos e indirectos del procedimiento y comparar los resultados de mamografía con los resultados histopatológicos. Es un estudio observacional, retrospectivo, con análisis de costos sobre las biopsias guiadas por arpón de microcalcificaciones mamarias sospechosas de malignidad, realizadas en el servicio de imagen del Hospital de Especialidades Carlos Andrade Marín, entre el 01 de enero de 2014 y el 31 de marzo de 2017. De un total de 38 pacientes, la media del costo total fue de 1312,19 dólares (SD 254,29 dólares), con un ratio medio para la biopsia guida por arpón para microcalcificaciones de 13,46. El 97,5% presentó microcalcificaciones en el histopatológico y el 15,8% carcinoma intraductal. En conclusión, la biopsia quirúrgica guiada por arpón en relación a microcalcificaciones sospechosas es efectiva, no obstante es menos costo efectiva que la biopsia por estereotaxia asistida al vacío. Debido al alto porcentaje de benignidad en el resultado histopatológico, se recomiendan estudios enfocados al análisis de categorización de las microcalcificaciones sospechosas de malignidad con variabilidad intra e interobservador.

Surgical biopsy guided by stereotaxy of mammary microcalcifications for a long time has long been considered the gold standard to determine the malignancy of the microcalcifications. The objectives are to perform an analysis of direct and indirect costs of the procedure and compare the results of mammography with the histopathological results. It is an observational, retrospective study, with cost analysis on the biopsies guided by harpoon of mammary microcalcifications suspicious of malignancy, carried out in the image service of the Hospital of Specialties Carlos Andrade Marín, between January 1, 2014 and March 31 of 2017. A total of 38 patients had a total cost average of 1312.19 dollars (SD 254.29 dollars), with a cost-effectiveness ratio for guided biopsy by harpoon for microcalcifications of 13.46. From histopathological results, 97.5% presented microcalcifications and 15.8% intraductal carcinoma. In conclusion, harpoon-guided surgical biopsy in relation to suspicious microcalcifications is effective, however it is less cost effective than vacuum assisted stereotaxy biopsy. Due to the high percentage of benignity in the histopathological result, studies focused on the analysis of categorization of microcalcifications suspicious of malignancy with intra- and inter-observer variability are recommended.

Basic interventional radiology in the abdomen. / Intervencionismo básico en abdomen.

This article describes the different basic nonvascular interventional techniques in the abdomen that all general radiologists should be familiar with. It explains the indications and approaches for the different procedures (punctures, biopsies, drainage of collections, cholecystostomies, and nephrostomies). It also discusses the advantages and disadvantages of the different imaging techniques that can be used to guide these procedures (ultrasound, CT, and fluoroscopy) as well as the possible complications that can develop from each procedure. Finally, it shows the importance of following up patients clinically and of taking care of catheters.
