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 Open Window Thoracostomy (OWT) surgical method find its origin in the treatment of chronic tuberculous empyemas, in the cases where the drainage alone not permitted a sufficient cleaning of pleural cavity. In the recent years the indications for the execution of this method are extended also to metapneumoniae and post-pneumonectomy empyemas (for benign and malignant pathology), with or without bronco-pleural fistula, when these pathologies produces a general severe decline in the patient (septic shock). This method permit to effect a daily cleaning of a pleural cavity, through the introduction of a sterile gauzes imbued of specific antibiotic, reducing at least the purulent infection effects's previously present and favouring the reduction of the same cavity, in prevision of other reconstructive operations (thoracoplasty). Generally not many beloved by surgeons and patients (for the difficult management, aesthetic outcomes, the long stay in hospital), the OWT can often reestablish a dangerous situation, especially in the patients with a risk of septic shock. This study aims to analyse present indications, problems and therapeutics outcomes of this method, through the evaluation of 27 cases of OWT treated in the Department of Thoracic Surgery University of L'Aquila between the 1984 and the 1998.

Background: The aim of this study was to evaluate the benefits of total intravenous anaesthesia (TIVA), with the administration of drugs intravenously and the maintenance of pulmonary ventilation with oxygen enriched air, with respect to inhalatory anaesthesia, in thoracotomies with single lung ventilation., Methods: The study, devoloped in collaboration between the Service of Anaesthesia and Resuscitation and the Division of Thoracic Surgery of the Hospital of Teramo, was carried out in two groups of patients chosen at random; fifty patients divided into two groups of twenty-five were studied. Pre-medication and induction was similar in both groups; maintenance, however, varied: a total intravenous anaesthesia was given to patients in group A whereas patients in group B received an inhalatory anaesthesia. These parameters were considered: pressure values, heartbeat, PaO2 and PaCO2 levels, SatO2 and EtCO2., Results: Both protocols respected anaesthetic guidelines in terms of controlling pressure values, heartbeat and levels of PaCO2 during bipulmonary ventilation. Significantly statistical differences were observed in the oxygenation during one lung ventilation: the mean values of PaO2 being significantly higher in group A., Conclusions: On the basis of this experience, it can be conclude that TIVA offers the following advantages: a better oxygenation during one lung ventilation, good recovery of post operative consciousness with no psychomotor disturbances, absence of pollution in the operating theatre.

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 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.

The combined surgical treatment of primitive lung cancer with single brain metastasis is a frequently debated but still controversial problem. Up to day several therapeutic approaches are generally integrated (surgery, radiotherapy, chemotherapy) according to the clinical patterns and the technical possibilities. In general, the combined surgical operation (thoracotomy + craniotomy) when it is possible to be done, followed or proceeded by chemo-radiotherapy, has allowed to achieve a prolonged survival in these patients, maintaining an acceptable quality of life. The authors analyze 10 cases treated by thoracotomy and craniotomy at the Chair of Thoracic Surgery of University of L'Aquila. Although consisting of a small number of cases, this experience allows to detect the particular problems concerning these patients. The indications to the combined surgical treatment are considered, evaluating the surgical operation which is to be performed as first on the basis of lung cancer staging and of the location and size of the brain metastases. Finally the patients survival and their quality of life are considered.

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 great interest in VATS over the last few years has extended the indications for this technique in order to avoid risks. There are additional indications (e.g. spontaneous pneumothorax), including several benign diseases of the lung, pleura, mediastinum and oesophagus. But other indications for the procedure are still controversial, for example lung resection for primary bronchial cancer. In this report the Authors, on the basis of their own experience, try to define the present and approaching perspectives for VATS.

Twenty-five patients with bronchogenic carcinoma were prospectively studied by both CT and MR during 10 days preceding thoracotomy. MR scans included contiguous axial and coronal slices. Results of CT and MR studies were compared with the surgical and pathological findings. Although no significant difference was found between the two imaging methods for the evaluation of mediastinal nodes. MR appear to be superior to CT in the aortopulmonary and subcarinal node areas.

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.

Cancer of the lung is becoming increasingly common. In the U.S., it has the highest mortality of the neoplastic diseases, well ahead of cancer of the colon and rectum. Surgical and/or complementary management is poorly effective because it comes too late. Early diagnosis and treatment are essential, therefore. Preclinical diagnosis may be possible radiographically in certain fortunate cases, but this is never an early diagnosis. The latter is only possible through active bronchial cytology (bronchial brushing, selective washing, PBS) during and after flexible fibrobronchoscopy, which can be carried out under local anaesthesia at the outpatient level and causes very little distress to the patient. Data from a personal series are cited in support of the view that cytodiagnosis should be routinely employed in subjects at high risk (heavy smokers, persons with chronic bronchitis, emphysema, etc.).

Twenty-two patients with surgically incurable lung cancer undergoing systemic chemotherapy have been studied with serial determinations of CEA levels during their therapy. The changes of CEA levels in each patients showed that the assay may be useful to evaluate the effects of therapy. The purpose of this preliminary study is to explore the possibility that CEA assay may be a useful guide to the subsequent clinical response of the patient to the drug.

In pursuance of an investigation of oesophageal physiopathology, a study has been made of the problem of the functional regulation of the inferior oesophageal sphincter in the light of new findings. Experiments carried out on six dogs made it possible to study functional modifications of the oesophagus after vagotomy, completing the technique by administering pentagastrin for the first time in vivo. Radiological and mano metric controls showed in the post-operative period a dilated oesophagus with a fall, in the lower third, of normal pressure values that did not undergo change, unlike what happened in the non-denervated oesophagus after administration of pentagastrin. The results obtained show that the integrity of the nervous structures is not only necessary for the perfect coordination of oesophageal peristalsis, but vital for normal functional response of the inferior oesophageal sphincter, since gastrin action is always mediated by release of acetylcholine by the post-gangliar vagal nerve endings.
