Abstract
Introduction and objectives

Interventional endoscopy allows us to act on the pathology of the patient with minimal discomfort, low costs and high efficiency. We assessed the validity of flexible endoscopic biopsies in our hospital, in lesions suspected of malignancy in the rhino-pharyngo-laryngeal space.

Subjects and methods

Retrospective study of patients with a pathology suspected of malignancy assessed between 2006 and 2016 in our centre. We evaluated the effectiveness, the tolerance and the number of complications. We calculated the cost reduction in comparison with direct laryngoscopy in the operating room. We compared our sample with others of similar characteristics described in the literature.

Results

Thirty patients were studied with a flexible endoscopic biopsy during that period. Nineteen patients obtained positive results which allowed them to start treatment for their pathology. Seven cases had no evidence of malignancy and required another biopsy under general anaesthesia, which confirmed the carcinoma diagnosis. Two samples ruled out malignancy which was confirmed by laryngeal microsurgery. One case showed inflammation and the lesion was cured after antibiotherapy. It was impossible to collect the sample in one case. Thus, we obtained sensitivity levels of 73% with a specificity of 100%. There were no complications. The cost reduction in our sample was above 80%.

Conclusions

Flexible endoscopic biopsy has advantages over direct laryngoscopy that are relevant in the diagnosis of oncological pathology in otorhinolaryngology.

Resumen
Introducción y objetivos

La endoscopia intervencionista nos permite actuar sobre la patología del paciente con mínimas molestias, bajos costes y alta eficiencia. Evaluamos la validez de la biopsia por endoscopia flexible en nuestro hospital, en las lesiones sospechosas de malignidad en el espacio rinofaringolaríngeo.

Material y método

Estudio retrospectivo de los pacientes con patología sospechosa de malignidad valorados en el periodo 2006-2016 en nuestro centro. Valoramos la eficacia, la tolerancia y número de complicaciones. Calculamos la reducción de costes frente a la laringoscopia directa en quirófano. Comparamos nuestra muestra con otras de características similares descritas en la bibliografía.

Resultados

Treinta pacientes fueron estudiados mediante biopsia por endoscopia flexible en ese período. Diecinueve pacientes obtuvieron resultados positivos que permitieron iniciar el tratamiento de su patología. Siete casos, sin evidencia de malignidad, requirieron nueva biopsia bajo anestesia general que confirmó el diagnóstico de carcinoma. Dos muestras descartaron malignidad, dato que se confirmó tras microcirugía de laringe. Un caso mostró inflamación y la lesión se resolvió tras antibioterapia. En un caso la toma de muestra resultó imposible. Obtenemos de esta forma niveles de sensibilidad del 73% con una especificidad del 100%. No se produjeron complicaciones. La reducción de costes en nuestra muestra fue superior al 80%.

Conclusiones

La biopsia por endoscopia flexible aporta ventajas sobre la laringoscopia directa que resultan de interés en el diagnóstico de patología oncológica en otorrinolaringología.
