ABSTRACT

Background: In the diagnostic process of pleural tuberculosis, the findings from video-assisted thoracoscopy (VATS) can be highly suggestive for the diagnosis of infection. Methods: We reviewed VATS records between the years 2012 to 2016 of patients over 16 years of age with pleural effusion and suspected pleural tuberculosis. Symptoms, macroscopic and chemical characteristics of the fluid, surgical descriptions and visual diagnosis of the surgeon were recorded and were compared with the histopathology. Results: 106 patients were selected, most of them men (71.7%), of whom approximately half were active military (51.3%). The predominant symptoms were dyspnea, pleuritic pain, fever and evolution time greater than 15 days (94.3%, 80.2%, 50% and 46,2%, respectively). These symptoms, in turn, were present more frequently in pleural tuberculosis patients than in non-tuberculosis patients. The fluid was mostly turbid yellow (44%) and lymphocytic cellularity exudate (77.4%). The VATS findings in patients with confirmed TBC included nodules (96.9%), adhesions (87.5%) and thickening (78.1%). The diagnosis made by the surgeon in relation to the histopathological diagnosis showed a sensitivity of 88.6% and a specificity of 98.4%. Conclusion: There are highly suggestive characteristics of the macroscopic report of VATS that would allow a quicker diagnosis of pleural tuberculosis.


Antecedentes: Los hallazgos de toracoscopia asistida por video (VATS) durante el diagnostico de tuberculosis pleural, que son altamente sugestivos de la infección han sido poco descritos. Metodos: Se revisaron los registros de VATS entre los años 2012 a 2016 of de pacientes mayores de 16 años con efusión pleural y sospechosos de etiología tuberculosa. Se analizaron los síntomas, las características macroscópicas y bioquímicas del líquido, la descripción quirúrgica y el diagnostico visual y se compararon con los resultados de la histopatologia. Resultados: Se estudiaron los registros de 106 pacientes, la mayoría fueron sexo masculino (71.7%), y aproximadamente la mitad en servicio militar activo (51.3%). Los síntomas predominantes fueron disnea, dolor pleuritico, fiebre y tiempo de evolución mayor a 15 días (94.3%, 80.2%, 50% y 46,2%, respectivamente). Estos sintomas a su vez fueron más frecuentes en tuberculosis pleural que en no tuberculosis. El liquido fue más amarillo turbio (44%) y con exudado de tipo linfocitario (77.4%). Los hallazgos de VATS en pacientes con tuberculosis confirmada incluyeron nodulos (96.9%), adhesiones (87.5%) y engrosamiento (78.1%). El diagnóstico hecho por el cirujano con relación al histopatológico, tuvo una sensibilidad de 88.6% y una especificidad de 98.4%. Conclusion: Existen características en el VATS altamente sugestivas de tuberculosis pleural.
