BACKGROUND@#Chronic cough after pulmonary resection is one of the most common complications, which seriously affects the quality of life of patients after surgery. Therefore, the aim of this study is to explore the risk factors of chronic cough after pulmonary resection and construct a prediction model.@*METHODS@#The clinical data and postoperative cough of 499 patients who underwent pneumonectomy or pulmonary resection in The First Affiliated Hospital of University of Science and Technology of China from January 2021 to June 2023 were retrospectively analyzed. The patients were randomly divided into training set (n=348) and validation set (n=151) according to the principle of 7:3 randomization. According to whether the patients in the training set had chronic cough after surgery, they were divided into cough group and non-cough group. The Mandarin Chinese version of Leicester cough questionnare (LCQ-MC) was used to assess the severity of cough and its impact on patients' quality of life before and after surgery. The visual analog scale (VAS) and the self-designed numerical rating scale (NRS) were used to evaluate the postoperative chronic cough. Univariate and multivariate Logistic regression analysis were used to analyze the independent risk factors and construct a model. Receiver operator characteristic (ROC) curve was used to evaluate the discrimination of the model, and calibration curve was used to evaluate the consistency of the model. The clinical application value of the model was evaluated by decision curve analysis (DCA).@*RESULTS@#Multivariate Logistic analysis screened out that preoperative forced expiratory volume in the first second/forced vital capacity (FEV1/FVC), surgical procedure, upper mediastinal lymph node dissection, subcarinal lymph node dissection, and postoperative closed thoracic drainage time were independent risk factors for postoperative chronic cough. Based on the results of multivariate analysis, a Nomogram prediction model was constructed. The area under the ROC curve was 0.954 (95%CI: 0.930-0.978), and the cut-off value corresponding to the maximum Youden index was 0.171, with a sensitivity of 94.7% and a specificity of 86.6%. With a Bootstrap sample of 1000 times, the predicted risk of chronic cough after pulmonary resection by the calibration curve was highly consistent with the actual risk. DCA showed that when the preprobability of the prediction model probability was between 0.1 and 0.9, patients showed a positive net benefit.@*CONCLUSIONS@#Chronic cough after pulmonary resection seriously affects the quality of life of patients. The visual presentation form of the Nomogram is helpful to accurately predict chronic cough after pulmonary resection and provide support for clinical decision-making.

BACKGROUND@#The relationship between quality of life at three months after lung cancer surgery and different surgical approaches is remains unclear. This study aimed to compare the quality of life of patients three months after uniportal and multiportal thoracoscopic lobectomy.@*METHODS@#Data from patients who underwent lung surgery at the Department of Thoracic Surgery, Sichuan Cancer Hospital between April 2021 and October 2021 were collected. The European Organization for Research and Treatment of Quality of Life Questionnaire-Core 30 (EORTC QLQ-C30) and Quality of Life Questionnaire-Lung Cancer 29 (EORTC QLQ-LC29) were used to collect quality of life data of the patients. Potential confounding factors in the baseline data were included in a multivariate regression model for adjustment, and the quality of life of the two groups three months postoperatively was compared with traditional clinical outcomes.@*RESULTS@#A total of 130 lung cancer patients were included, with 57 males (43.8%) and 73 females (56.2%), and an average age of (57.1±9.5) yr. In the baseline data of the two groups, there was a statistical difference in the number of chest drainage tubes placed (P<0.001). After adjustment with the regression model, at three months postoperatively, there were no significant differences in all symptoms and functional status scores between the two groups (all P>0.05). The multiportal group had longer surgery time (120.0 min vs 85.0 min, P=0.001), postoperative hospital stay (6.0 d vs 4.0 d, P=0.020), and a higher incidence of early ≥ grade 2 complications (39.0% vs 10.1%, P=0.011) compared to the uniportal group.@*CONCLUSIONS@#Patients undergoing uniportal and multiportal thoracoscopic lobectomy have similar quality of life at three months postoperatively. The uniportal group may have certain advantages in terms of traditional clinical outcome indicators such as operation time, postoperative hospital stay, and early postoperative complications.

BACKGROUND@#Patients with pulmonary nodules are treated by minimally invasive surgery, and postoperative symptoms have become the main factors affecting patients' emotion and quality of life. This study aimed to analyze the changes of postoperative symptoms in lung cancer patients with pulmonary nodules.@*METHODS@#The clinical data of eighty-eight lung cancer patients admitted to the same medical group of Department of Thoracic Surgery, West China Hospital of Sichuan University from June 2021 to September 2021 were prospectively collected and analyzed. The types and severity of clinical symptoms before operation, on discharge day, 30-day and 90-day after operation were analyzed.@*RESULTS@#The incidence of postoperative symptoms in lung cancer patients was 79.5%, and most patients suffered from mild (54.3%) and moderate (32.9%) symptoms. The main postoperative symptoms of lung cancer patients were pain (55.7%) and cough (37.2%). The incidence of pain at discharge (55.7%) was significantly higher than that at 30-day (23.7%, P=0.01) and 90-day (12.0%, P=0.01) after discharge. The incidence of cough was significantly higher at 30-day (66.1%) and 90-day (66.0%) than that at discharge (37.2%) (P=0.01, P=0.04).@*CONCLUSIONS@#The main postoperative symptoms of lung cancer patients with pulmonary nodules are pain and cough. The incidence and severity of pain decreases with time, and the incidence of cough increases but the severity decreased gradually.

BACKGROUND@#To investigate the correlation between the reduction of lung volume and the degree of lung function damage after lobectomy.@*METHODS@#A total of 131 patients (72 males and 59 females) who underwent thoracoscopic lobectomy in the First Affiliated Hospital of Suzhou University from January 2019 to July 2020 (including thoracoscopic resection of left upper lobe, left lower lobe, right upper lobe, right middle lobe and right lower lobe). In order to compare the difference between postoperative pulmonary function and preoperative pulmonary function, the pulmonary function measurements were recorded at 7 days before operation, and 3 months, 6 months and 1 year after operation. Forced expiratory volume in 1 second (FEV1) was used as the main evaluation parameter of pulmonary function. The original lung volume and the remaining lung volume at each stage were calculated by Mimics Research 19.0 software. The correlation between lung volume and lung function was analyzed.@*RESULTS@#FEV1 in postoperative patients was lower than that before operation, and the degree of decline was positively correlated with the resection volume of lung lobes (the maximum value was shown in the left lower lobe group). Significantly, there was no significant difference in the degree of pulmonary function reduction between 3 months, 6 months and 1 year after operation.@*CONCLUSIONS@#The decrease of lung tissue volume after lobectomy is the main reason for the decrease of lung function, especially in the left lower lobe. And 3 months after lobectomy can be selected as the evaluation node of residual lung function.

Introducción: el secuestro pulmonar es una patología poco frecuente en la edad adulta, su mayor incidencia es en etapas tempranas de la vida. Se acompaña de infecciones pulmonares a repetición o crónicas severas, y puede asociarse a malformaciones congénitas. El diagnóstico se fundamenta en la detección de la irrigación anómala a través de un vaso de la circulación sistémica. Este caso nos permite plantear un diagnóstico diferencial en pacientes de edad adulta, aún cuando se trate de patología con mayor incidencia en niños y jóvenes, y poder orientar el manejo de acuerdo a esta posibilidad diagnóstica. Caso clínico: paciente femenino, de 19 años, con antecedente de asma e infecciones respiratorias a repetición de un mes de evolución. Ingresa con dificultad respiratoria, fiebre y tos productiva. Se realiza tomografía y Radiografía de tórax, en la que se evidencia imágenes compatibles con colección en campo pulmonar izquierdo y derrame pleural. Se realiza BAAR en esputo con resultado negativo para tuberculosis. Se realiza toracotomía posterolateral izquierda, resección de lóbulo inferior izquierdo, y se coloca dren pleural. Se identifica absceso pulmonar en lóbulo inferior izquierdo, y hallazgos anatómicos de secuestro pulmonar. Paciente presenta evolución favorable; el control clínico y radiográfico en el postoperatorio inmediato y mediato fue satisfactorio. Conclusión: presentamos el caso de edad adulta, donde un diagnóstico adecuado y un manejo multidisciplinario permiten una evolución satisfactoria de los pacientes.(AU)

Introduction: pulmonary sequestration is a rare disease in adulthood; its highest incidence is in early stages of life. It is accompanied by repeated or severe chronic lung infections, and may be associated with congenital malformations. The diagnosis is based on the detection of anomalous irrigation through a vessel of the systemic circulation.This case allows us to propose a differential diagnosis in patients of adulthood, even when it is pathology with higher incidence in children and young people, and guide the management according to this diagnostic possibility.Clinical case: female patient, 19 years old, with a history of asthma and respiratory infections after a month of evolution. The patient was admitted with respiratory distress, fever and productive cough.A tomography and chest X-ray are performed; that show images compatible with collection in the left pulmonary field and pleural effusion. BAAR is performed in sputum with a negative result for tuberculosis.Posterolateral left thoracotomy is performed, left lower lobe resection, and pleural drain is placed. Pulmonary abscess is identified in the left lower lobe, and findings of anatomical pulmonary sequestration. Patient presents positive evolution; The clinical and radiographic control in the immediate and intermediate postoperative period was satisfactory.Conclusion: we present the case of adulthood, where an adequate diagnosis and multidisciplinary management allows a satisfactory evolution of the patient.(AU)

Abstract Introduction: Significant anatomical and functional changes occur following pneumonectomy. Mediastinal structures displace toward the side of the resected lung, pulmonary reserve is reduced. Owing to these changes, surgical access to heart and great vessels becomes challenging, and there is increased risk of postoperative pulmonary complications. Methods: We performed a mitral valve replacement combined with a Ravitch procedure in a young female with previous left pneumonectomy and pectus excavatum. Results: She was discharged on postoperative day 9 and remains symptom-free 3 months after surgery. Conclusion: Thorough preoperative evaluation and intensive respiratory physiotherapy are essential before performing cardiac operations on patients with previous pneumonectomy.

Abstract Background and objectives: Cardiac tamponade is potentially fatal medical condition, which rarely occurs as a complication of lung lobectomy. We present the first case of cardiac tamponade to develop in a Post-Anesthesia Care Unit following a lung lobectomy. Case report: A 54-year-old man with pulmonary squamous cell carcinoma underwent an apparently uncomplicated lung lobectomy. His hemodynamics was unremarkable throughout the surgery and initially in the Post-Anesthesia Care Unit. However, after 5 min in the Post-Anesthesia Care Unit, he suddenly became hypotensive and dyspneic. He responded poorly to inotropics and fluid resuscitation. Transesophageal echocardiography conducted by an anesthesiologist who suspected a cardiac etiology revealed a pericardial effusion compressing the heart. After a failed attempt of pericardiocentesis, an emergency pericardial window operation was performed. The patient improved dramatically once the heart was decompressed. Conclusion: Since cardiac tamponade is generally not suspected as a cause of hemodynamic instability after a lung lobectomy, as it was in this case, a misdiagnosis of the patient's condition may have led to improper management resulting in death. As anesthesiologists are often involved in the initial resuscitation of morbid patients in Post-Anesthesia Care Units, their acquaintance with various postoperative complications and competence in echocardiography for assessing cardiac problems may contribute to patient survival.

Resumo Justificativa e objetivos: O tamponamento cardíaco é uma condição médica potencialmente fatal, cuja ocorrência como uma complicação da lobectomia pulmonar é muito rara. Apresentamos o primeiro caso de tamponamento cardíaco desencadeado na sala de recuperação pós-anestésica (SRPA) após uma lobectomia pulmonar. Relato de caso: Paciente do sexo masculino, 54 anos, com carcinoma de células escamosas pulmonares, submetido à lobectomia pulmonar aparentemente sem complicações. Sua hemodinâmica não apresentou alteração durante toda a cirurgia e também inicialmente na sala de recuperação pós-anestésica. Porém, após cinco minutos na SRPA, o paciente apresentou hipotensão e dispneia de forma repentina e respondeu mal ao inotrópico e à reanimação hídrica. Uma ecocardiografia transesofágica feita por um anestesiologista que suspeitou de etiologia cardíaca revelou um derrame pericárdico que comprimia o coração. Após tentativa malsucedida de pericardiocentese, foi feita uma janela pericárdica de emergência. O paciente apresentou melhoria dramática com a descompressão do coração. Conclusão: Como o tamponamento cardíaco geralmente não é suspeito como causa de instabilidade hemodinâmica após lobectomia pulmonar, como ocorreu neste caso, um diagnóstico errado da condição do paciente poderia ter levado a um manejo inadequado, que resultaria em morte. Como os anestesiologistas estão frequentemente envolvidos na reanimação inicial de pacientes debilitados em salas de recuperação pós-anestésica, seu conhecimento de várias complicações pós-operatórias e competência na ecocardiografia para avaliar problemas cardíacos podem contribuir para a sobrevivência do paciente.

ABSTRACT Objective: To describe our experience with video-assisted thoracic surgery (VATS) for anatomic pulmonary resection at a referral center for thoracic surgery in Brazil. Methods: All patients who underwent anatomic pulmonary resection by VATS between 2010 and 2015 were included. Clinical and pathological data, as well as postoperative complications, were analyzed. Results: A total of 117 pulmonary resections by VATS were performed, of which 98 were lobectomies and 19 were anatomic segmentectomies. The mean age of the patients was 63.6 years (range, 15-86 years). Females predominated (n = 69; 59%). The mean time to chest tube removal was 2.47 days, and the mean length of ICU stay was 1.88 days. The mean length of hospital stay was 4.48 days. Bleeding ≥ 400 mL occurred in 15 patients. Conversion to thoracotomy was required in 4 patients. Conclusions: Our results are similar to those published in major international studies, indicating that VATS is an important strategy for pulmonary resection. They also show that VATS can be safely performed with adequate training. This technique should be used more often for the treatment of lung diseases in Brazil.

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.

A ressecção pulmonar é o tratamento de escolha no carcinoma brônquico, sendo a lobectomia o tipo de cirurgia de eleição nesta situação. A sublobectomia é um tipo de ressecção menos invasiva com maior preservação de parênquima pulmonar e pode ser uma alternativa à lobectomia em estágios iniciais da doença. Na literatura existe apenas um estudo clínico randomizado comparando as duas intervenções, e vários estudos de série de casos. Avaliar a eficácia da sublobectomia como tratamento cirúrgico no câncer de pulmão tipo carcinoma de não-pequenas células em estádios iniciais quando comparada com a lobectomia. Revisão e metanálise proporcional de série de casos em artigos que comparam os resultados da sublobectomia com os da lobectomia no tratamento do carcinoma de pulmão de não-pequenas células. Os estudos foram identificados na base de dados MEDLINE via PubMed, Embase e Lilacs. Referências bibliográficas também foram pesquisadas para encontrar estudos não indexados. A análise estatística foi realizada através do programa StatsDirect 2.7.9. Foram selecionados 21 artigos para essa metanálise, incluindo 19678 pacientes, sendo 17397 submetidos à lobectomia e 2281, à sublobectomia. Não houve diferença estatística na sobrevida em cinco anos entre os dois tipos de ressecção. A mortalidade pós-operatória analisada em 15 estudos também não apresentou diferença significante entre os dois tipos de ressecção. A recorrência local e a distância possíveis de serem avaliadas em nove artigos também não mostraram diferença estatisticamente significante, mas uma tendência da recorrência local ser maior na sublobectomia...

Pulmonary resection is the treatment of choice in bronchogenic carcinoma, lobectomy being the type of surgery of choice in this situation, the sublobectomy is a type of resection less invasive with greater preservation of lung parenchyma and can be an alternative to lobectomy for stage initial disease. In the literature there is only one randomized clinical trial comparing the two interventions, and several case series studies. To evaluate the effectiveness of sublobectomy as surgical treatment in non-small cell lung carcinoma in the early stages when compared with lobectomy. A review and meta-analysis proportional of cases series studies comparing the results with those of sublobectomy and lobectomy in the treatment of non-small cell lung carcinoma. Studies were identified in MEDLINE, Embase and Lilacs. References were also searched to find studies not indexed. Statistical analysis was performed using the program StatsDirect 2.7.9. 21 articles were selected for this meta-analysis, including 19678 patients, 17397 in lobectomy and 2281 in sublobectomy. There was no statistical difference in five-year survival between the two types of resection. The postoperative mortality analyzed in 15 studies also showed no significant difference between the two types of resection. The local and distant recurrence were able to be evaluated in nine studies showed no statistically significant difference, but a tendency of local recurrence was higher in sublobectomy...

El síndrome postneumonectomía es una entidad poco frecuente en pediatría. Comunicamos un caso secundario a una neumonectomía realizada por un tumor intratorácico. Niño de 4 años con antecedente de exéresis pulmonar derecha y dificultad respiratoria progresiva, con obstrucción extrínseca de la vía aérea por estructuras mediastínicas desplazadas. Hubo intentos frustros de tutorización con dispositivos endoluminales de la vía aérea, e imposibilidad de retiro de la asistencia ventilatoria mecánica. Ante la imposibilidad de reposicionamiento mediastinal, se realiza puente (bypass) aórtico con tubo protésico, con evolución favorable y egreso hospitalario.

Postpneumonectomy syndrome is a rare entity in children. We report a case secondary to pneumonectomy performed due to an intrathoracic tumor. A 4-year-old boy with a history of right pneumonectomy and progressive respiratory distress, with extrinsic airway obstruction due to displaced mediastinal structures. There were failure to intubate the airway with endoluminal devices and impossibility of withdrawing from mechanical ventilation. As mediastinal repositioning was not possible, an aortic bypass with a prosthetic tube graft was performed, with favorable outcome and hospital discharge.

Pneumonectomy is associated with high rates of morbimortality, with postpneumonectomy pulmonary edema being one of the leading causes. An intrinsic inflammatory process following the operation has been considered in its physiopathology. The use of corticosteroids is related to prevention of this edema, but no experimental data are available to support this hypothesis. We evaluated the effect of methylprednisolone on the remaining lungs of rats submitted to left pneumonectomy concerning edema and inflammatory markers. Forty male Wistar rats weighing 300 g underwent left pneumonectomy and were randomized to receive corticosteroids or not. Methylprednisolone at a dose of 10 mg/kg was given before the surgery. After recovery, the animals were sacrificed at 48 and 72 h, when the pO2/FiO2 ratio was determined. Right lung perivascular edema was measured by the index between perivascular and vascular area and neutrophil density by manual count. Tissue expression of vascular endothelial growth factor (VEGF) and transforming growth factor-beta (TGF-β) were evaluated by immunohistochemistry light microscopy. There was perivascular edema formation after 72 h in both groups (P = 0.0031). No difference was observed between operated animals that received corticosteroids and those that did not concerning the pO2/FiO2 ratio, neutrophil density or TGF-β expression. The tissue expression of VEGF was elevated in the animals that received methylprednisolone both 48 and 72 h after surgery (P = 0.0243). Methylprednisolone was unable to enhance gas exchange and avoid an inflammatory infiltrate and TGF-β expression also showed that the inflammatory process was not correlated with pulmonary edema formation. However, the overexpression of VEGF in this group showed that methylprednisolone is related to this elevation.

Chylothorax is a relatively rare complication associated with thoracic surgery. It tends to occur in the early postoperative period. The prevalence ranges from 1 - 2%, and without treatment, the mortality rate is around 50%. Chylothorax after a pulmonary resection is usually diagnosed within three days after surgery. Only a few cases of delayed diagnosis have been reported in literature until now and almost all of them have been reported to occur within 15 days of surgery. Early recognition and prompt treatment are essential. We report a case of delayed onset chylothorax after pneumonectomy with literature review

Sporadic reports on cardiac herniation are available in the literature; most of them had followed intrapericardial pneumonectomies for malignant pulmonary tumors. We present an uncommon event of heart herniation after a completion pneumonectomy indicated for chronic bronchiectasis. A 35-year-old male patient was operated for left completion pneumonectomy. A 6 cm Χ 4 cm area of adherent pericardium near the obtuse margin of heart was removed during surgery. During head-end elevation of the bed in postoperative intensive care unit, patient got accidentally tilted to the left side, which resulted in ventricular fibrillation. Chest cavity was re-opened for cardiopulmonary resuscitation. Left ventricle was found herniating through the pericardial deficiency into the left-thoracic cavity with the cardiac apex touching chest wall. During surgical re-exploration, the pericardial deficiency was closed with a synthetic Dacron patch. Hemodynamic condition remained stable in the immediate postoperative period. Patients had infection of the left thoracic cavity after 5 weeks, for which he was subjected to thoracoplasty and omentopexy. Prompt recognition with timely intervention is life saving from cardiac herniation. Strategy of closing the pericardial defect after pneumonectomy should be followed routinely, irrespective of the indication for pneumonectomy.

Los abscesos pulmonares son tratados corrientemente con antibióticos y drenaje postural. Sin embargo, algunos pacientes no resuelven con las medidas conservadoras o presentan contraindicaciones para el tratamiento quirúrgico convencional. En tales individuos, el drenaje percutáneo (técnica de Monaldi) puede ser una alternativa de valor. El objetivo de este trabajo fue la presentación de 3 pacientes a quienes se les realizó el drenaje percutáneo de abscesos pulmonares. Se describen la técnica empleada para la inserción del tubo, las complicaciones y la evolución posoperatoria de los pacientes. En los 3 casos la operación fue exitosa, sin mortalidad y con una sola complicación, que fue una fístula broncopleurocutánea que requirió una intervención (neumonectomía) ulterior. El drenaje percutáneo de los abscesos pulmonares fue seguro y efectivo en estos pacientes(AU)

The pulmonary abscesses are usually treated with antibiotics and postural drainage. However, some patients don't improve with conservative measures or have contraindications for conventional surgical treatment. The aim of present paper was the presentation of three cases underwent percutaneous drainage of pulmonary abscesses. The technique used for tube insertion, complications and postoperative course of patients were described. In such cases operation was successful without mortality and with a bronchopleural cutaneous fistula like the only complication requiring a further intervention (pneumonectomy). The percutaneous drainage of pulmonary abscesses was safe and effective in our patients(AU)
