RESUMO
Objetivo. Demostrar la fiabilidad y las aplicaciones que presenta la ecografía intraoperatoria (EIO) en el manejo quirúrgico y terapéutico de diversas patologías, así como la posibilidad de utilización de equipos convencionales para su realización. Material y métodos. Estudio retrospectivo unicéntrico de 145 EIO realizadas con equipos convencionales a 135 pacientes entre enero de 2011 y junio de 2016. Se valoraron los órganos estudiados mediante EIO, las enfermedades de base de los pacientes y las pruebas de imagen preoperatorias, y se analizó el grado de concordancia de la EIO con las mismas y con los resultados histológicos en los casos en que se obtuvo muestra de tejido, así como las funciones que desempeñó la EIO en el tratamiento de los pacientes. Resultados. El 91,7% de las ecografías realizadas fueron hepáticas, siendo otras localizaciones variadas menos frecuentes. Estas presentaron una alta concordancia con los resultados histológicos de las lesiones analizadas (95,4%), y en el 24% de los casos sus resultados no coincidieron con los de las pruebas de imagen preoperatorias, siendo determinantes para el tratamiento de los pacientes. Conclusión. A pesar de las limitaciones de nuestro estudio, la EIO ha demostrado ser una prueba fiable con ventajas frente a las pruebas de imagen convencionales. Ayuda a llegar a un diagnóstico en aquellas lesiones no caracterizables mediante las pruebas de imagen preoperatorias, a localizar y delimitar la extensión de una lesión dentro de un órgano, y facilita la realización de procedimientos diagnósticos (biopsia intraoperatoria) incluso en centros donde no se dispone de sondas específicas (AU)
Objective. To prove both the reliability and the applications presented by intraoperative ultrasonography (IOUS) in surgical and therapeutic management of diverse pathologies and the possibility of doing it by using conventional equipment. Material and methods. Single-center retrospective study of 145 IOUS performed by using conventional equipment in 135 patients between January 2011 and June 2016. We assessed the organs studied by ultrasound, underlying conditions of patients, preoperative imaging and the degree of matching them with the histological findings. The functions of the intraoperative ultrasound were assessed in each case. Results. 91,7% of the scans performed were hepatic, being other locations varied but less common. They had a high concordance with the histological results of the lesions analyzed (95.4%) and in 24% of the cases their results did not coincide with those of the preoperative imaging tests, being decisive for the management of the patients. Conclusion. Despite the limitations of our study, IOUS has proven to be a reliable and safe diagnostic test with advantages over conventional imaging techniques. It contributes to get a correct diagnosis in those lesions not characterized by the preoperative imaging tests, to locate and delimit the extension of a lesion within an organ and facilitate the performance of diagnostic procedures (intraoperative biopsy) even in centers where we do not have specific probes (AU)
