OBJECTIVE: To describe demographic characteristics, surgical results, postoperative complications, and overall survival rates in surgically treated patients with lung metastases. METHODS: This was a retrospective analysis of 119 patients who underwent a total of 154 lung metastasis resections between 1997 and 2011. RESULTS: Among the 119 patients, 68 (57.1%) were male and 108 (90.8%) were White. The median age was 52 years (range, 15-75 years). In this sample, 63 patients (52.9%) presented with comorbidities, the most common being systemic arterial hypertension (69.8%) and diabetes (19.0%). Primary colorectal tumors (47.9%) and musculoskeletal tumors (21.8%) were the main sites of origin of the metastases. Approximately 24% of the patients underwent more than one resection of the lesions, and 71% had adjuvant treatment prior to metastasectomy. The rate of lung metastasis recurrence was 19.3%, and the median disease-free interval was 23 months. The main surgical access used was thoracotomy (78%), and the most common approach was wedge resection with segmentectomy (51%). The rate of postoperative complications was 22%, and perioperative mortality was 1.9%. The overall survival rates at 12, 36, 60, and 120 months were 96%, 77%, 56%, and 39%, respectively. A Cox analysis confirmed that complications within the first 30 postoperative days were associated with poor prognosis (hazard ratio = 1.81; 95% CI: 1.09-3.06; p = 0.02). CONCLUSIONS: Surgical treatment of lung metastases is safe and effective, with good overall survival, especially in patients with fewer metastases.
RESUMO: Objetivo:Conduziu-se este estudo prospectivo a fim de avaliar-se a influência do uso da braçadeira sobre o acúmulo de coágulos dentro dos drenos pleurais. Método: Os drenos pleurais foram pesados logo após sua retirada, lavados e secados e pesados novamente. A diferença entre a primeira e a segunda pesagem foi admitida como a quantidade de coágulos acumulada. Resultados: Houve maior acúmulo de coágulo nos drenos temporariamente obstruídos por braçadeira em relação àqueles não obstruídos. Conclusão: Notou-se, neste estudo, maior acúmulo de coágulo dentro de drenos pleurais obstruídos, mesmo que intermitentemente, o que pode levar ao mau funcionamento de todo o sistema de drenagem. A discussão sobre o correto uso dos drenos pleurais deve ser constante e fazer parte de programas de educação continuada para médicos e enfermagem, a fim de que este sistema, amplamente utilizado e altamente eficiente, seja otimizado (Rev. Col. Bras. Cir. 2008; 35(2): 079-082). AgradecimentosAgradecemos à colaboração dos laboratórios de patologia clínica do Hospital Estadual Sumaré e do Hospital das Clínicas da Unicamp por ceder seus equipamentos de precisão e seu espaço físico. Congratulamo-nos com a equipe de enfermagem do Hospital Estadual Sumaré pela predisposição à discussão e à educação continuada. ABSTRACT Background: A prospective study was done to evaluate the influence of clamp usage on clot formation inside thoracic drains.Methods: Each drain was weighed soon after removal; they were then washed, dried and weighed again. The difference between the first and second weights was taken as the amount of clot deposit formed. Results: We found more clots accumulated inside the drains that were temporarily obstructed by the clamp. Conclusion: In this study, there were more clots formation inside thoracic drains clamped, even if they were occluded intermittently. This can lead thoracic drains to function improperly. The discussion about the correct usage of thoracic drains must be a subject for educational programs for physicians and nurses, to aim for the safest use of this widely used and highly efficient system.
