Efficacy and safety of single-trocar technique for minimally invasive surgery of the chest in the treatment of noncomplex pleural disease.
OBJECTIVE: To assess the efficacy and the safety of a single-trocar technique for minimally invasive surgery of the chest in the management of multiple noncomplex thoracic diseases, a prospective study was performed and the results are presented. METHODS: Between October 1998 and December 2001, 100 patients underwent video-assisted thoracic surgery through a single trocar. The patients were divided into 4 groups as follows: (1) benign, (2) malignant, (3) pleural effusion, and (4) empyema. The following data were analyzed: age, sex, forced vital capacity, forced expiratory volume in 1 second, percentage of the predicted forced expiratory volume in 1 second, type of anesthesia, anesthesia time, surgery time, intraoperative complications, morbidity, chest tube removal, hospital stay, and follow-up. RESULTS: The patient population consisted of 64 men and 36 women with a mean age of 62 years (range 31-92 years). General anesthesia was used in 53 patients (25 double-lumen and 28 single-lumen tube) and local anesthesia and sedation in 47 patients. Talc pleurodesis was performed in 55 patients. Mean operative time was 65 +/- 37 minutes, 48 +/- 18 minutes for simple and 67 +/- 37 minutes (P =.004) for complex pleural effusion. Mean anesthesia time was 102 +/- 85 minutes. Chest tubes were removed after 5 +/- 2 days. Mean overall hospital stay was 6 +/- 3 days, 5 +/- 2 days for benign diseases, 7 +/- 3 days for malignant diseases, and 8 +/- 3 for empyema. Morbidity was present in 19 patients. Two patients had intraoperative bleeding; 1 required a mini-thoracotomy to control it. There was no hospital mortality. Three patients had wound infection, and no patient with malignant diseases had port site metastasis. CONCLUSION: Video-assisted thoracic surgery through a single trocar is simple, effective, and beneficial for all patients in the diagnosis and treatment of noncomplex diseases of the chest. Furthermore, with this newest type of technologically advanced instrumentation it is possible to carry out simple intrathoracic procedures without using additional ports.

Right intraventricular hydatid cyst of the heart.
A 32-year-old woman presented with shortness of breath and palpitations. Echocardiography and contrast-enhanced computed tomography showed a 4 x 5 cm cyst in the apex of the right ventricle. The cyst was excised on cardiopulmonary bypass. The patient made an uneventful recovery. At the one-year follow-up, she was symptom-free and without recurrence. Different clinical aspects of cardiac hydatid cyst and its surgical management are reviewed.

Pulmonary vein gas analysis for assessing donor lung function.
BACKGROUND: Radial artery oxygenation (PaO2) is the standard method for assessing potential lung donors. This study was proposed to assess the use of pulmonary vein gases (PvO2) in selection of donor lung for transplantation. METHODS: We studied 170 lungs from 85 consecutive donors. Lungs were classified into group A, PaO2 and PvO2 > 300 mm Hg; group B, PaO2 < 300 mm Hg, and PvO2 > 300 mm Hg; and group C, PvO2 < 300 mm Hg. RESULTS: Lungs retrieved from group A and group B were used for transplantation. Allograft function, assessed by the arterial and alveolar oxygen tension ratio, was similar at 12 hours and at 24 hours after operation (0.69, 0.73, vs 0.70, 0.71, for groups A and B, respectively (p = 0.8, 0.7, respectively). Similar radiologic appearance was seen in both groups (p = 0.2). Median duration of intubation was also similar (p = 0.6). The 30-day mortality rate was 12% versus 11.3% (p = 0.8), and 1-year survival rate was 80% versus 82% (p = 0.8) for recipient received lungs from group A and B donors, respectively. CONCLUSIONS: Selective pulmonary veins analysis gives an accurate assessment of individual gas exchange in comparison with arterial PaO2, identifying more potential donor lungs for transplantation.

Four-step local anesthesia and sedation for thoracoscopic diagnosis and management of pleural diseases.
STUDY OBJECTIVES: Most thoracic surgeons perform thoracoscopy under general anesthesia using a double-lumen endotracheal tube. We describe our own technique for performing thoracoscopy under local anesthesia and sedation. DESIGN, SETTING, PATIENTS: Forty-five patients underwent the procedure under local anesthesia and sedation (mean age, 64 years; age range, 40 to 92 years). A known history of cancer was present in 12 patients. American Society of Anesthesiology score was I in 1 patient, II in 16 patients, III in 22 patients, IV in 5 patients, and V in 1 patient. Premedication was comprised of droperidol, 5 mg, and atropine, 0.5 mg, administered 20 min before the scheduled operating room time. Sedation was maintained by diazepam injection, 3 mg. Four-step local anesthesia in the planned intercostal space using 10 mL of ropivacaine, 7.5 mg/mL, was performed. RESULTS: Mean operative time was 45.7 min (range, 20 to 90 min); mean time of anesthesia was 71.3 min (range, 30 to 150 min). Among patients with pleural effusion, 23 effusions were simple and 16 effusions were complex. Talc was administrated in 28 patients. Complications were intraoperative bleeding (one patient), hyperpyrexia (eight patients), and atrial fibrillation (two patients). The mean time for removal of the chest drain was 5.6 days (range, 2 to 13 days). Postoperative hospital stay was 6.4 days (range, 2 to 14 days). No hospital mortality occurred. Follow-up is complete in all patients (mean, 92.8 days; range, 31 to 270 days). CONCLUSION: Four-step local anesthesia and sedation is a simple and effective method of performing a video-assisted thoracic procedure to diagnose and treat simple thoracic pathologies.

[Malignant pleural mesothelioma in housewives in the province of Catania].
Our study reports pleural malignant mesothelioma (PMM) in seven female patients. All patients were resident in Catania area (Sicily), the median age was 69.2 years and ranged from 59 to 81 years. They were housewife. Their anamnesis was negative for both direct and indirect previous exposure to asbestos; the partners of all patients were also not exposed to asbestos. The exposure to X-rays was also excluded for these patients. Different pathogenetic mechanisms for the appearance of PMM in these patients can be hypothesized, for example, SV40 infection and genetic susceptibility; a minimal domestic exposure to asbestos can be not excluded. Therefore, further studies in a more large number of subjects are necessary to determine whether one or all of these hypothetic pathogenetic mechanisms are more significant for the develop of PMM.
