Congenital lung malformations are rare and vary widely in their clinical presentation and severity, depending mostly on the degree of lung involvement and their location in the thoracic cavity. They can manifest at any age and can be the source of significant morbidity and mortality in infants and children. Individuals with congenital lung malformations can present with respiratory symptoms at birth or can remain asymptomatic for long periods. Recently, there has been an increase in the early diagnosis of these malformations, a change that is attributable to the routine use of prenatal ultrasound. The clinical manifestation of these malformations varies from respiratory distress in the immediate postnatal period to an incidental finding on chest X-rays. Early diagnosis and prompt treatment offer the possibility of absolutely normal lung development. The treatment of asymptomatic patients with lung malformations is controversial, because the prognosis of these diseases is unpredictable. The management of these lesions depends on the type of malformation and symptoms. Because of the risk of complications, most authors recommend resection of the lesion at the time of diagnosis. Lobectomy is the procedure of choice and yields excellent long-term results. This article describes the principal congenital lung malformations, their diagnosis, and the controversies regarding treatment.Keywords: Cystic adenomatoid malformation of lung, congenital; Bronchopulmonary sequestration; Pulmonary surgical procedures; Diagnosis. ResumoAs malformações congênitas do pulmão são raras e variam muito na sua forma de apresentação clínica e gravidade, dependendo principalmente do grau de envolvimento pulmonar e de sua localização na cavidade torácica. Elas podem se manifestar em qualquer idade e podem ser fonte de importante morbidade e mortalidade em lactentes e crianças. Os indivíduos com malformações congênitas do pulmão podem apresentar sintomas respiratórios ao nascimento, enquanto outros podem permanecer assintomáticos por longos períodos. Atualmente, com o uso rotineiro da ultrassonografia pré-natal, vem ocorrendo um aumento no diagnóstico mais precoce dessas malformações. A manifestação clínica dessas malformações varia desde uma disfunção respiratória pós-natal imediata a um achado acidental na radiografia de tórax. O diagnóstico precoce e o tratamento imediato oferecem a possibilidade de um desenvolvimento pulmonar absolutamente normal. Quando assintomáticos, a conduta para o tratamento dos pacientes com malformações pulmonares ainda é controversa, uma vez que o prognóstico dessas afecções é imprevisível. O manejo dessas lesões depende do tipo de malformação e de sintomas. Devido ao risco de complicação, a maioria dos autores sugere a ressecção da lesão no momento em que essa é identificada. A lobectomia é o procedimento de escolha, fornecendo excelentes resultados a longo prazo. Este artigo descreve as principais malformações pulmonares congênitas, seu diagnóstico e controvérsias quanto o tratamento. (5) is covered by ...

Objective: This prospective study aimed at investigating predictive factors for compensatory sweating after thoracoscopic sympathectomy. Methods: From 2000 to 2002, 80 patients (53 females and 27 males) underwent thoracoscopic sympathectomy to treat hyperhidrosis. Patient ages ranged from 12 to 56 years, and the mean postoperative follow-up period was 42.51 ± 5.98 months. Patient satisfaction with the results was evaluated through the use of a rating scale. The procedure was performed bilaterally: at the T2 level for facial hyperhidrosis; at the T3-T4 level for axillary hyperhidrosis; and at the T3 level for palmar hyperhidrosis. Results: Post-operatively, 68 patients (85.0%) presented compensatory sweating, which was classified as mild in 23 (33.8%), moderate in 23 (33.8%) and severe in 22 (32.4%). Considering the final surgical results, 70 patients (87.5%) were satisfied with the outcome of the operation, whereas 10 patients (12.5%) were dissatisfied. The level of patient satisfaction varied according to gender, age, body mass index (BMI) and extent of denervation. The compensatory sweating was more severe on the abdomen and back than on the legs. Conclusions: Although compensatory sweating, which is a common adverse effect of sympathectomy, occurred in the majority of cases, the level of patient satisfaction was high. The best candidates for thoracoscopic sympathectomy are young adult women with a BMI ≤ 24.9 kg/m 2 .Keywords: Sympathectomy; Hyperhidrosis; Thoracoscopy; Postoperative complications; Thoracic surgery, video-assisted. ResumoObjetivo: Este estudo prospectivo visou investigar fatores preditivos para a hiperidrose compensatória após a simpatectomia toracoscópica. Métodos: De 2000 a 2002, 80 pacientes (53 mulheres e 27 homens), com idade entre 12 e 56 anos, foram submetidos à simpatectomia toracoscópica para o tratamento de hiperidrose e acompanhados em média por 42,51 ± 5,98 meses. A satisfação destes pacientes quanto aos resultados do procedimento foi aferida por meio de uma escala de avaliação. O procedimento foi executado bilateralmente: no nível de T2 para a hiperidrose facial; de T3 e T4 para a hiperidrose axilar; e de T3 para a hiperidrose palmar. Resultados: No período pós-operatório, 68 pacientes (85,0%) apresentaram hiperidrose compensatória, que foi classificada como leve em 23 (33,85%), moderada em 23 (33,8%) e grave em 22 (32,4%). Quanto aos resultados da cirurgia, na avaliação dos pacientes, 70 deles (87,5%) se consideraram satisfeitos, enquanto 10 pacientes (12,5%) disseram estar insatisfeitos. O grau de satisfação do paciente variou de acordo com o sexo, a idade, o índice de massa corpórea (IMC) e a extensão da operação. A hiperidrose compensatória foi mais intensa no abdome e dorso do que nas pernas. Conclusões: Embora a hiperidrose compensatória seja um efeito adverso frequente após a simpatectomia, o grau de satisfação dos pacientes foi elevado. Os melhores candidatos para simpatectomia toracoscópica são mulheres adultas jovens com IMC ≤ 24,9 kg/m 2 .

Objective: To determine the main congenital lung malformations treated and the principal diagnostic methods employed, as well as the indications for surgical treatment and the results obtained, at a referral facility for pediatric thoracic surgery. Methods: We reviewed the medical charts of 52 patients anatomopathologically diagnosed with congenital lung malformations and who had been submitted to pulmonary resection between January of 1997 and December of 2006. Exclusion criteria were age ≥ 12 years and incomplete clinical data. The final sample comprised 35 patients. Results: In this sample, the mean age was 31 months, and there was a predominance of males (n = 21). The anatomopathological findings were cystic adenomatoid malformation (n = 14), congenital lobar emphysema (n = 13), pulmonary sequestration (n = 8) and arteriovenous malformation (n = 1). The most common type of lung resection was left lower lobectomy (in 25.71%) followed by different types of segmentectomy (in 22.85%), left upper lobectomy (in 22.85%), right upper lobectomy (in 14.28%), right lower lobectomy (in 8.57%) and middle lobectomy (in 5.71%). Of the 35 patients, 34 (97.14%) were submitted to closed pleural drainage, with a mean duration of thoracic drainage of 3.9 days. Ten patients (28.5%) presented with postoperative complications. There were no deaths in our sample. Conclusions: Pulmonary resection for the treatment of congenital lung malformations is a safe procedure, presenting low morbidity and no mortality at a referral facility for pediatric thoracic surgery.Keywords: Cystic adenomatoid malformation of lung, congenital; Bronchopulmonary sequestration; Pneumonectomy; Pulmonary surgical procedures; Pulmonary emphysema.

Some lung diseases are true diagnostic challenges due to their various clinical presentations. Actinomycosis is one such disease, potentially affecting various organs and systems. We report the case of a patient with pulmonary actinomycosis as a pseudotumor, which is usually only diagnosed by thoracotomy or thoracoscopy.

Esophageal reconstruction is one of the most complex types of gastrointestinal surgery, principally when it is performed using minimally invasive techniques. The procedure is associated with various complications, such as anastomotic dehiscence, chylothorax, esophageal necrosis and fistulae. We report the case of a patient diagnosed with epidermoid carcinoma in the distal third of the esophagus. The patient was submitted to esophagectomy by video-assisted thoracoscopy and laparoscopy. During the operation, the left main bronchus was injured, and this required immediate surgical correction. In the postoperative period, the patient presented with acute respiratory failure and profuse air leak through the thoracic drains and through the cervical surgical wound. The patient underwent a second surgical procedure, during which a large lesion was discovered in the membranous wall of the trachea. The lesion was corrected with an intercostal muscle pedicle flap.

Objective To evaluate the contribution that unilateral thoracic sympathectomy in dominant side or two-stage bilateral thoracic sympathectomy can have as strategies to reduce the incidence of compensatory sweating after sympathectomy for palmar hyperhidrosis. Methods This is a prospective, controlled, randomized multicenter trial of 200 participants with palmar hyperhidrosis, which will be randomized into two arms: (a) one-stage bilateral thoracic sympathectomy (control arm); or (b) unilateral thoracic sympathectomy in dominant side (intervention arm). At six months the participants submitted to unilateral procedure can make the contralateral surgery if they wanted it, creating a third group called two-stage bilateral sympathectomy. Participants will be evaluated for the degree of sweating by the Hyperhidrosis Disease Severity Scale (HDSS) and of quality of life questionnaires. Results 96 participants out of the 200 proposed have been included so far, with 48 participants randomized to each arm. From the sample 61 (63.5%) are female, with a mean age of 24 (20–32) years. There were exclusive palmar hiperhydrosis in 14 cases (14.5%), palmar and plantar hyperhidrosis in 36 (37.5%) cases, palmar and axillar hyperhidrosis in 12 (12,5%) cases and palmar-axillary-plantar hyperhidrosis in 34 (35,4%) cases. The age at the beginning of the disease was childhood (78%), with mean of time of disease 15 (11–22) years. Conclusions If one or both hypothesis: (a) unilateral sympathectomy in dominant hand is a satisfactory treatment; b) two-stage bilateral sympathectomy causes less compensatory sweating than in one stage are confirmed there is a chance that surgical therapy for palmar hyperhidrosis can be changed for better.

The thoracic outlet syndrome results in the neurovascular structures compression in the designated region of the space between the collarbone and the first rib (thoracic outlet). May be divided between classic neurogenic or true, atypical neurogenic or vascular, and each one of them has a different compression mechanism and can be represented by a bony anomalous structure, costoclavicular reduction space or by the arm's hyper abduction. The diagnosis is complex, and complementary exams such as: radiography, MRI, angiography helps in the viewing of the involved structure. The treatment may be done in two ways: conservative (exercises for posture correction and muscular strengthening, combined with symptomatic treatment) and surgical, (the base is a resection of the first rib and may be associated with scalenectomy or cervical rib resection). The surgical technique by videothoracoscopic video-assisted surgery is poorly reported, therefore, technically attractive and related to less invasiveness and greater safety. In this article, it will be revised the facts about the pathology and its therapeutic approach.
