An evaluation of all pediatric patients with primary or secondary pulmonary disease operated upon from January 1993 to July 1996 by the same senior surgeon was carried out. The inclusion criterion was a lung resection in patients aged less than 14 years. Children were divided into two categories according to the neoplastic or non-neoplastic nature of their disease. In the first group a lobectomy was performed for primary lesions and wedge resection for secondary ones. In the second group lobar emphysema and cystic dysplasia were the major indications for lobectomy, while diagnostic wedge resections were performed for interstitial/infiltrative lesions. Several groups of techniques were identified according to the type of approach and the suture method. Video-assisted thoracoscopic surgery and a muscle-sparing approach were compared to classic posterolateral thoracotomy. The mechanical stapler-suturing method was compared to the manual suturing. Our results demonstrate the importance of mechanical suturing, particularly in decreasing anesthesia time and reducing the risk of dehiscence. The minimally invasive approach associated with mini-thoracotomy was particularly useful for patients with reduced oxygen saturation due to ventilatory and gas-exchange problems. The roles of staplers in lung parenchymal resection and minimally invasive procedures for improving the postoperative thoracic compliance of pediatric patients are stressed.
