[Pulmonary biopsy by thoracoscopy: techniques and results in 9 patients].

Video-assisted endoscopic techniques have decreased the surgical aggression in abdominal and thoracic surgery. In our country, pediatric laparoscopy has been developing slowly, but this is not the case for thoracoscopy. The aim of this paper is to present the techniques and results of thoracoscopy pulmonary biopsy in our first patients. Pulmonary biopsies with this approach had been done in 9 patients (5 males, 3 females). Their age ranged between 30 months and 16 years. In all cases this was the last resort for the diagnosis of pulmonary condensation of unknown etiology. The biopsies were done with the pretied knot in 5 cases, stappler in 1 case and with biopsy forceps in 2 cases. Thoracotomy was necessary in one patient, due to intraoperative haemorrhage. Enough tissue for bacterial and pathological diagnosis was obtained. There was not mortality nor important morbidity related with the technique. Postoperative recovery is better when compared with conventional thoracotomy. Thoracoscopy is an adequate approach to perform pulmonary biopsies in children. The advantages if we compare with open thoracotomy are: 1. The possibility to choose the are to perform a minimally invasive biopsy. 2. To take samples of different pulmonary lobes. 3. Less postoperative pain and shorter hospital stay (36-48 hours).
