          ABSTRACT

          Objective:

          The objective of this study was to describe the results of anatomic pulmonary resections performed by video-assisted thoracoscopy in Brazil.

          Methods:

          Thoracic surgeons (members of the Brazilian Society of Thoracic Surgery) were invited, via e-mail, to participate in the study. Eighteen surgeons participated in the project by providing us with retrospective databases containing information related to anatomic pulmonary resections performed by video-assisted thoracoscopy. Demographic, surgical, and postoperative data were collected with a standardized instrument, after which they were compiled and analyzed.

          Results:

          The surgeons provided data related to a collective total of 786 patients (mean number of resections per surgeon, 43.6). However, 137 patients were excluded because some data were missing. Therefore, the study sample comprised 649 patients. The mean age of the patients was 61.7 years. Of the 649 patients, 295 (45.5%) were male. The majority-521 (89.8%)-had undergone surgery for neoplasia, which was most often classified as stage IA. The median duration of pleural drainage was 3 days, and the median hospital stay was 4 days. Of the 649 procedures evaluated, 598 (91.2%) were lobectomies. Conversion to thoracotomy was necessary in 30 cases (4.6%). Postoperative complications occurred in 124 patients (19.1%), the most common complications being pneumonia, prolonged air leaks, and atelectasis. The 30-day mortality rate was 2.0%, advanced age and diabetes being found to be predictors of mortality.

          Conclusions:

          Our analysis of this representative sample of patients undergoing pulmonary resection by video-assisted thoracoscopy in Brazil showed that the procedure is practicable and safe, as well as being comparable to those performed in other countries.

          RESUMO

          Objetivo:

          O objetivo deste estudo foi descrever os resultados de ressecções pulmonares anatômicas por videotoracoscopia no Brasil.

          Métodos:

          Cirurgiões torácicos (membros da Sociedade Brasileira de Cirurgia Torácica) foram convidados, por correio eletrônico, a participar do estudo. Dezoito cirurgiões participaram do projeto enviando seus bancos de dados retrospectivos referentes a ressecções anatômicas de pulmão por videotoracoscopia. Dados demográficos, cirúrgicos e pós-operatórios foram coletados em um instrumento padronizado e posteriormente compilados e analisados.

          Resultados:

          Dados referentes a 786 pacientes foram encaminhados (média de 43,6 ressecções por cirurgião), sendo 137 excluídos por informações incompletas. Logo, 649 pacientes constituíram nossa população estudada. A média de idade dos pacientes foi de 61,7 anos, 295 eram homens (45,5%), e a maioria - 521 (89,8%) - foi submetida à cirurgia por neoplasia, mais frequentemente classificada como estádio IA. A mediana do tempo de drenagem pleural foi de 3 dias, e a do tempo de internação, 4 dias. Dos 649 procedimentos realizados, 598 (91,2%) foram lobectomias. A taxa de conversão para toracotomia foi de 4,6% (30 casos). Complicações pós-operatórias ocorreram em 124 pacientes (19,1%), sendo pneumonia, escape aéreo prolongado e atelectasia as mais frequentes. A mortalidade em 30 dias foi de 2,0%, tendo como preditores idade avançada e diabetes.

          Conclusões:

          A casuística brasileira mostra que as ressecções pulmonares por cirurgia torácica videoassistida são factíveis e seguras, além de comparáveis àquelas de registros internacionais.

          Systemic inflammatory response syndrome criteria in defining severe sepsis.

          The consensus definition of severe sepsis requires suspected or proven infection, organ failure, and signs that meet two or more criteria for the systemic inflammatory response syndrome (SIRS). We aimed to test the sensitivity, face validity, and construct validity of this approach.

              Video-assisted thoracic surgery lobectomy: report of CALGB 39802--a prospective, multi-institution feasibility study.

              To evaluate the technical feasibility and safety of video-assisted thoracic surgery (VATS) lobectomy for small lung cancers. The Cancer and Leukemia Group B 39802 trial was a prospective, multi-institutional study designed to elucidate the technical feasibility of VATS in early non-small-cell lung cancer (NSCLC) using a standard definition for VATS lobectomy (one 4- to 8-cm access and two 0.5-cm port incisions) that mandated videoscopic guidance and a traditional hilar dissection without rib spreading. Between 1998 and 2001, 128 patients with peripheral lung nodules < or = 3 cm in size with suspected NSCLC were prospectively registered for VATS lobectomy. One hundred twenty-seven patients (66 males and 61 females; median age, 66 years; range, 37 to 86 years), with a performance status of 0 (74%) or 1 (26%), underwent surgery. Patients with lymph nodes more than 1 cm by computed tomography scan underwent mediastinal lymph node sampling to rule out N2 disease. One hundred eleven patients (87%) had stage I lung cancer, and 96 (86.5%) of these 111 patients underwent successful VATS lobectomies. The median procedure length was 130 minutes (range, 47 to 428 minutes), and median chest tube duration was 3 days (range, 1 to 14 days). Fifty-eight (60%) of 97 patients underwent diagnostic biopsy at lobectomy. Within 30 days, three (2.7%) of 111 patient deaths occurred, none of which were directly related to VATS technique; seven (7.4%) of 95 patients had grade 3 or greater complications, with only one case of bleeding. A standardized approach to VATS lobectomy as specifically defined with avoidance of rib spreading is feasible.
