Objective To examine the diagnostic and therapeutic role of fiber-optic and rigid bronchoscopy in pediatric patients with foreign body inhalations. Methods From January 1986 to December 2004, we observed 128 young patients with suspicion of foreign body aspiration. Patients were divided into 3 groups: group I, patients with negative chest X-ray; group II, patients with radiological direct signs; group III, patients with radiological indirect signs. Results Removal of the foreign body was effected in 105 patients by rigid bronchoscopy and in 13 patients by fiber-optic bronchoscopy. In 3 group II patients a thoracotomy with a bronchotomy was necessary. Conclusions Fiber-optic bronchoscopy showed a diagnostic accuracy rate of 100 % but played a poor therapeutic role with a case resolution of 10.7 %. Rigid bronchoscopy was the main technique, permitting the removal of the tracheobronchial foreign body in 97.2 % of patients.

Surgical tracheostomy morbidity led the authors to investigate new election techniques. The aim of this retrospective study was to assess the translaryngeal tracheostomy (TLT), complications and cost.From January 1998 to January 2001, 104 patients were treated with TLT modified: 69 males (66.3%) and 35 females (33.7%), average age 52.6 +/- 9.5 years. The original pathologies were: traumatical (36), neurological (37), surgical (9), heart (4), respiratory (18). The average time between intubation and execution of TLT was 4.2 +/- 1.3 days.Fifty four patients died (52%) and 50 patients lived (48%). Two complications (1.9%) occurred in those who survived: a breaking of the guidewire in traction. Extraction of the tracheostomy tube by clamp, a haemorrhage in 2nd post-operative day due to a thyroid vessel lesion. The haemostasis was performed by classical tracheostomy. The average number of days to decannulation was 25 +/- 1 days.TLT reduces trauma or trachea and neighbouring structures. This technique is safe and easy. TLT is an effective method, in non-urgent situations, in children and adults, as well as in brachytypes and the obese.

Bullous pneumopathy is considered a surgical disease, although her treatment is still discussed. The initial attempts of surgical treatment were founded on erroneous physiopathological concepts and date back to early years of 1900. These surgical treatments intended to external drainage of giant bullae, their marsupialized or to reduction of extension of bullae by pneumoperitonaeum, section of phrenic nerve or thoracoplasty. The definition of emphysematous bullae has been much improved with the development of computed tomography. A precise study of their size, of their position and of condition of residual pulmonary parenchyma may be considered important to decide the surgical treatment: this must determine the removal of bulla and the reexpansion of compressed pulmonary parenchyma. The Authors report a case of giant bulla, initially wrong interpreted as pneumothorax, of exceptional observation for her malformative origin, diagnoses and surgical treated on an eleven years old child.

The aim of this work was to evaluate the different surgical repair procedures and to discuss their technical applications according to the indications. From april 1989 to november 1999 we observed 18 patients, 12 males (66.7%) and 6 females (33.3%) presenting tumors of the chest wall. All patients were submitted preoperatively to a general respiratory check-up, and to an assessment of loco-regional and metastatic lesions. In 13 patients (72.2%), on the basis of topographical and morphological characteristics of the mass, we performed a transthoracic needle biopsy under scanner monitoring. The exeresis, in 6 patients (33.3%), implied a large resection of osteo-muscular structures. In 10 patients (55.6%), the benign nature of lesion, required extirpation solely of the tumor. In 2 patients (11.1%), owing to the extensive infiltration of the primary neoplasm, solely complementary treatment was carried out. Reconstruction of the thoracic wall was performed using associated myoplasty in all cases. In 3 subjects a prosthesis was installed; in 1 case a costal transposition association is necessary. Histological observation of the excised material revealed 16 primary tumors, 12 benign (75%) and 4 malignant (25%). Transthoracic needle biopsy under scanner monitoring confirmed the diagnosis in 100% of the cases operated. Fourteen patients (87.5%) are alive 73 +/- 35 months after intervention, without resumption of the disease. Two patients died (12.5%) VIII and VI months following the operation. Two patients not operated, died after VI and V months. Appropriate choice of techniques and of repair materials allowed valid oncological, aesthetical and functional results independently from the extent of the parietal defect.

The Authors carried out an retrospective analysis on 81 patients, 67 men and 14 women, suffering from non post-surgical thoracic empyema, to evaluate the different therapeutic procedures and respective indications. The unsuccessful response to the preserving approach (intercostal drainage and pleural lavage twice a day with specific antibiotics or antiseptics) in 56 cases, induced the Authors to carry out a video-thoracoscopy (VAT), that allowed them to define the infection stage and subsequent treatment (the carrying on of a pleural drainage-lavage in 32 cases, the transcurrent pleural irrigation in 10 cases, the open window thoracostomy followed by myoplasty in 6 cases with bronchopleural fistula, the decortication with associated pleural exeresis in 6 cases with bronchopleural fistula, the decortication with associated pleural exeresis in 6 cases, the streptokinase in pleural cavity in 2 cases). There were registered totally 3 deaths (3.7%). The Authors in conclusion assert that the VAT, carried out after the unsuccessful preserving treatment, allows the evaluation of the infection stage and consequently suggests therapy.

The aim of this study is to evaluate the utility of surgical treatment in patients with pectus excavatum (PE) or pectus carinatum (PC). Fifteen patients underwent surgical treatment because of their psycological and anatomical condition, more serious in 6 patients (5 with PE and 1 with PC). The degree of these chest wall deformities was evaluated as resulting from CT scan of the thorax, by the ratio between the transversal and the front/back diameters, according to Haller. The Authors recommend surgical operation in the post-puberal age up to 21 years because of good results obtained using Ravitch approach (only 1 case of partial relapse of PE), even though modified in PE cases with the application of flat steel prosthesis and in PC cases for uncutting the perichondral beds. The choice of surgical procedure derives, in our opinion, from the correction of these anatomic deformities and from the greater sense of improved cosmesis that might result.

Clinical research on 75 cases of mediastinal masses has been carried out with the aim of evaluating the diagnostic value of Magnetic Resonance (MR). Results which have been achieved point to a remarkable potentiality of MR especially in the characterization and spatial definition of the masses and in the study of the spinal canal. These results, as well as the non-invasivity of the procedure, lead us to consider MR as an investigation of primary importance in the diagnostic assessment of mediastinal pathology.

The diagnostic significance of the histological typing of lung cancer carried out on preoperative bronchoscopic biopsy samples is assessed in relation to final morphological diagnosis on operating material. In this connection 176 of 624 cases of lung cancer documented histologically from January 1980 to December 1987 in which preoperative biopsy sample was followed by removal of the lung are analysed. The 4 basic histotypes of lung cancer according to the WHO (1981) classification are considered. A positive diagnosis for cancer was encountered in 138 cases (78.4%) with histotype confirmed in 122, whereas a negative diagnosis was encountered in 38 cases (21.6%). These findings also permitted further considerations, including the possible limitations of the technique.

Interstitial implantation of I125 by thoracotomy represents a further therapeutic procedure for lung cancer. Two cases recently treated by this procedure are reported. The first case concerns a right apical carcinoma of the lung where interstitial implantation of I125 seeds was carried out in the unresectable apical neoplastic residue, after superior lobectomy. The second case concerns a smaller tumor unresectable due to the severely impaired respiratory function. Main indications to the procedure are reported.
