Fundamento. Mostrar la eficacia que supone colocar un arp車n espiral en n車dulos pulmonares bajo control de tomograf赤a computarizada para su posterior resecci車n por cirug赤a m赤nimamente invasiva. Material y m谷todos. Se localizaron quince n車dulos de 0,5-1,5 cm en quince pacientes de los cuales diez ten赤an antecedentes de neoplasia, con la colocaci車n de arp車n espiral modelo Somatex, de 120 mm de longitud y 18 G de Laboratorios L谷leman, S.L., a trav谷s de tomograf赤a computarizada, resec芍ndose por cirug赤a m赤nimamente invasiva. Resultados. Tras la resecci車n del n車dulo se comprob車 que en los quince casos el arp車n estaba junto al n車dulo o englobando al mismo -tal como se hab赤a colocado en el esc芍ner-, objetiv芍ndose en dos casos una peque a hemorragia intraparenquimatosa y en uno de ellos un peque o neumot車rax. El tiempo de la colocaci車n del arp車n oscil車 entre quince y treinta minutos. Conclusi車n. Marcar un n車dulo pulmonar con arp車n tipo espiral es un m谷todo sencillo que permite anclar con seguridad el n車dulo para su posterior resecci車n por cirug赤a m赤nimamente invasiva. Background. To show the efficacy of placing a spiral harpoon in pulmonary nodules under the control of computerised tomography for their subsequent resection by minimally invasive surgery. Materials and methods. Fifteen nodules of between 0.5-1.5 cm were localised in fifteen patients, of whom ten had antecedents of neoplasia, with the placement of spiral harpoon model Somatex, of 120mm length and 18 G of Laboratorios L谷leman, S.L., by means of computerised tomography, resecting them by minimally invasive surgery. Results. Following the resection of the nodule it was confirmed that in the fifteen cases the harpoon was next to the nodule or encompassing it - just as it had been placed on the scanner, in two cases objectifying a small intraparenchymatose haemorrhage and in one case a small pneumothorax. The time taken to place the harpoon oscillated between fifteen and thirty minutes. Conclusion. Marking a pulmonary nodule with a spiral type harpoon is a simple method that makes it possible to securely anchor the nodule for its subsequent resection by minimally invasive surgery.
