Pulmonary blastoma: treatment through sleeve resection of the right upper lobe

Blastoma pulmonar: tratamento cirúrgico por lobectomia superior direita e broncoplastia

Abstract PDF PT PDF EN Portuguese Text

Pulmonary blastoma is a rare lung tumor that is composed of malignant epithelial and mesenchymal cells. It presents a pattern of rapid growth. Herein, we report the case of a patient with hemoptysis and a mass in the right upper lobe. The patient presented limited pulmonary function, and fiberoptic bronchoscopy revealed invasion of the intermediate bronchus. The patient underwent sleeve resection of right upper lobe, a technique never before described. After 36 months of follow-up, the patient remained asymptomatic. We also review the literature regarding treatment, clinical aspects and pathology.

Experimental pleural empyema in rats: effect of the intrapleural administration of dextran 40 during the fibrinopurulent stage

Pleural empyema carries high morbidity and mortality rates. Therapy focuses on the control of the infectious process in its initial phase when parenteral antibiotics and chest drainage are likely to be most effective. The ability of dextrans in preventing peritoneal adhesions leads one to test their potential effectiveness in reducing fibrinous proliferation in a rat model of pleural empyema. Twenty-four Wistar rats weighing 250-400 grams were anesthetized, submitted to a right thoracotomy and then randomized into 3 groups (n = 8 each). Animals in group I were given intrapleural dextran 40 (1 ml/kg) + 1 ml/kg of Staphylococcus aureus extract (1010 cells/ml) in heart-brain culture media obtained from oropharyngeal swabs of the animals. Animals in group II received saline solution (1 ml/kg) +1 ml/kg of Staphylococcus aureus extract (1010 cells/ml) in heart-brain culture media. Animals in group III (controls) were given the culture media without bacteria (1 ml/kg) in addition to saline (1 ml/kg). Upon completion, the chest was deaired, the thoracotomy wound was closed, the animals recovered, observed for 4 days, and sacrificed. Only the animals in groups I and II developed pleural effusion and empyema (average volume of 9.7 ml and 8.1 ml respectively, p > 0.05, NS). There was a significant weight loss in groups I and II compared to control animals (p = 0.004). There were no significant differences in blood work-up tests between groups. The pleural fluid of all animals in groups I and II had positive cultures for Staphylococcus aureus. The biochemical analysis of the pleural fluid in animals from groups I and II did not show any significant differences. The authors concluded that in this novel and reliable model of pleural empyema in rats, the intrapleural administration of dextran 40 at time of inoculation of bacteria did not result in any measurable reduction of the pleural reaction after 96 hours of observation.

Lobectomy for treating bronchial carcinoma: analysis of comorbidities and their impact on postoperative morbidity and mortality

Lobectomia por carcinoma brônquico: análise das co-morbidades e seu impacto na morbimortalidade pós-operatória

Objective: To analyze the impact that comorbidities have on the postoperative outcomes in patients submitted to lobectomy for the treatment of bronchial carcinoma. Methods: A retrospective study of 493 patients submitted to lobectomy for the treatment of bronchial carcinoma was conducted, and 305 of those patients met the criteria for inclusion in the final study sample. The surgical technique used was similar in all cases. The Torrington-Henderson scale and the Charlson scale were used to analyze comorbidities and to categorize patients into groups based on degree of risk for postoperative complications or death. Results: The postoperative (30-day) mortality rate was 2.9%, and the postoperative complications index was 44%. Prolonged air leakage was the most common complication (in 20.6%). The univariate analysis revealed that gender, age, smoking, neoadjuvant therapy and diabetes all had a significant impact on the incidence of complications. The factors found to be predictive of complications were body mass index (23.8 ± 4.4), forced expiratory volume in one second (74.1 ± 24%) and the ratio between forced expiratory volume in one second and forced vital capacity (0.65 ± 0.1). The scales employed proved efficacious in the identification of the risk groups, as well as in drawing correlations with morbidity and mortality (p = 0.001 and p < 0.001). In the multivariate analysis, body mass index and the Charlson index were found to be the principal determinants of complications. In addition, prolonged air leakage was found to be the principal factor involved in mortality (p = 0.01). Conclusion: Reductions in forced expiratory volume in one second, in the ratio between forced expiratory volume in one second and forced vital capacity, and in body mass index, as well as a Charlson score of 3 or 4 and a Torrington-Henderson score of 3, were associated with a greater number of postoperative complications in patients submitted to lobectomy for the treatment of bronchial carcinoma. Air leakage was found to be strongly associated with mortality.

Endobronchial inflammatory pseudotumor: a case report

Pseudotumor inflamatório endobrônquico: relato de caso

Pablo Gerardo Sanchez, Gabriel Ribeiro Madke, Eduardo Sperb Pilla, Rafael Foergnes, José Carlos Felicetti, Enio do Valle, Geraldo Geyer

J Bras Pneumol.2007;33(4):484-486

Abstract PDF PT PDF EN Portuguese Text

Inflammatory pseudotumor of the lung is a rare form of benign neoplasia and is generally characterized by a solitary pulmonary nodule. The endobronchial presentation is uncommon. Conservative surgery remains the treatment of choice, and surgeons should always strive to achieve tumor-free margins due to the possibility of local recidivism. This article reports the case of a 36-year-old male patient with recurrent attacks of wheezing and cough. The patient underwent successful bronchoplasty for the resection of an endobronchial inflammatory pseudotumor.
