Reconstrução da parede torácica após a ressecção de extensos tumores / Reconstruction of chest wall after resection of large tumors

INTRODUÇÃO: Nos estágios finais da reconstrução torácica, consequente a exéreses tumorais, são necessários procedimentos complexos e implantes. O que requer cuidados multidisciplinares, com a participação dos cirurgiões torácicos, plástico, radiologista e fisioterapeuta. O objetivo foi descrever as opções de reconstrução torácica após ressecção de neoplasia, realizado no Hospital Sarah Brasília. MÉTODO: Estudo retrospectivo de reconstrução torácica em tempo único, após excisão de tumor, fisioterapia respiratória com ventilação não invasiva e exercícios. RESULTADOS: Entre 2007 a 2012 foram operados 10 pacientes, sete homens e três mulheres; idade 10 a 31 anos; oito apresentavam tumores torácicos metastáticos (osteosarcoma, sinoviosarcoma, Fibrosarcoma epitelioide esclerosante e Rabdomiosarcoma) e dois originários da parede torácica (fibromatose e condrosarcoma). Observou-se boa evolução no pós-operatório imediato, com extubação ao final da cirurgia, retirada do dreno torácico entre 5° e 8° PO. As complicações foram: atelectasia (10%), recorrência tumoral (10%), e óbito em 3 (30%) casos . CONCLUSÃO: Foi possível a reconstrução torácica em tempo único utilizando tela de polipropileno, polimetilmetacrilato e retalhos musculares, com recuperação precoce da função pulmonar e baixo índice de complicações imediatas.

INTRODUCTION: Complex procedures and implants are required in the final stages of chest wall reconstruction after tumor excision. This process requires multidisciplinary care with participation from thoracic and plastic surgeons, a radiologist, and a physical therapist. The goal of this study was to describe the options for chest wall reconstruction after neoplasm resection at Hospital Sarah Brasilia. METHOD: A retrospective study of one-time chest wall reconstruction after tumor excision, respiratory physical therapy with noninvasive ventilation, and exercises was conducted. RESULTS: Between 2007 and 2012, 10 patients underwent surgery (seven men, three women; age range: 10-31 years); eight patients had metastatic thoracic tumors (e.g., osteosarcoma, synovial sarcoma, sclerosing epithelioid fibrosarcoma, and rhabdomyosarcoma) and two had tumors originating from the chest wall (fibromatosis and chondrosarcoma). The outcomes were good after the immediate postoperative period, with extubation occurring at the end of surgery and chest tube removal between the fifth and eighth postoperative day. Three cases (30%) involved complications of atelectasis (10%), tumor recurrence (10%), or death. CONCLUSION: One-time chest wall reconstruction using polypropylene mesh, polymethylmethacrylate, and muscle flaps was possible and was associated with early recovery of pulmonary function and a low rate of immediate complications.

Computed tomography guided needle biopsy: experience from 1,300 procedures.

CONTEXT AND OBJECTIVE: Computed tomography (CT) guided biopsy is widely accepted as effective and safe for diagnosis in many settings. Accuracy depends on target organ and needle type. Cutting needles present advantages over fine needles. This study presents experience from CT guided biopsies performed at an oncology center. DESIGN AND SETTING: Retrospective study at Hospital do Câncer A. C. Camargo, São Paulo. METHODS: 1,300 consecutive CT guided biopsies performed between July 1994 and February 2000 were analyzed. Nodules or masses were suspected as primary malignancy in 845 cases (65%) or metastatic lesion in 455 (35%). 628 lesions were thoracic, 281 abdominal, 208 retroperitoneal, 134 musculoskeletal and 49 head/neck. All biopsies were performed by one radiologist or under his supervision: 765 (59%) with 22-gauge fine-needle/aspiration technique and 535 (41%) with automated 16 or 18-gauge cutting-needle biopsy. RESULTS: Adequate samples were obtained in 70-92% of fine-needle and 93-100% of cutting-needle biopsies. The specific diagnosis rates were 54-67% for fine-needle and 82-100% for cutting-needle biopsies, according to biopsy site. For any site, sample adequacy and specific diagnosis rate were always better for cutting-needle biopsy. Among 530 lung biopsies, there were 84 pneumothorax (16%) and two hemothorax (0.3%) cases, with thoracic drainage in 24 (4.9%). Among abdominal and retroperitoneal biopsies, there were two cases of major bleeding and one of peritonitis. CONCLUSION: Both types of needle showed satisfactory results, but cutting-needle biopsy should be used when specific diagnosis is desired without greater incidence of complications.
