Uniportal versus triportal video-assisted thoracic surgery in the treatment of tuberculous empyema.

OBJECTIVE: To examine the effectiveness of decortication to treat chronic tuberculous empyema (TE) using uniport video-assisted thoracoscopic surgery (VATS) versus conventional triport VATS. METHODS: Data from consecutive patients with stage II or III TE who underwent decortication with either uniport VATS (uniportal group) between July and December 2017, or triport VATS between January and July 2018 (triportal group), were retrospectively analysed. VATS procedures were performed under general anaesthesia with double lumen endotracheal intubation and clinical outcomes were compared between the two groups. RESULTS: Clinical data were comparable between the groups (20 patients in each) regarding demographic and baseline characteristics, operative and postoperative characteristics, surgical procedure-related complications, and postoperative adverse events. No surgical procedure-related complications occurred during the perioperative period in either group. Threshold values for mechanical pain at 8 h postoperatively were significantly higher in the triportal group versus the uniportal group. Furthermore, the incidence of nausea and vomiting was significantly lower in the uniportal versus triportal group. In the triportal group, one patient required readmission and further intervention due to recurrence. CONCLUSIONS: Uniport VATS decortication for stages II and III TE may be a feasible and safe procedure in selected patients. Moreover, uniport VATS may be less painful than triport VATS.

A nomogram to predict residual cavity formation after thoracoscopic decortication in chronic tuberculous empyema.

OBJECTIVES: The goal of this study was to develop and validate a nomogram for predicting residual cavity formation after video-assisted thoracoscopic decortication in patients with chronic tuberculous empyema (CTE). METHODS: We retrospectively analysed patients who were diagnosed and treated for CTE at our hospital from January 2017 to December 2020. We used univariable and binary logistic regression analyses to identify independent risk factors. A predictive nomogram was developed and validated for predicting the risk of residual cavity formation after video-assisted thoracoscopic decortication in patients with CTE. The receiver operating characteristic (ROC) was used to evaluate the nomogram. RESULTS: Data from 103 patients were analysed. The contact area between the lung and empyema (P = 0.001, odds ratio [OR] 1.017, 95% confidence interval [CI] 1.007-1.028), calcification (P = 0.004, OR 0.12, 95% CI 0.029-0.501) and thickness of the pleura (P = 0.02, OR 1.315, 95% CI 1.045-1.654) were risk factors for residual cavity formation after video-assisted thoracoscopic decortication. A 50% residual cavity formation rate was used as the cut-off to validate the nomogram model. The area under the ROC curve for the nomogram was 0.891 (95% CI, 0.82-0.963). The sensitivity and specificity of the nomogram were 86.67% and 82.19%, respectively. The calibration curve indicated good consistency between the predicted and actual risks. CONCLUSIONS: The preliminary nomogram could contribute to preventing postoperative residual cavity formation and making appropriate surgical decisions.

Tuberculous Empyema Post Bilateral Lung Transplant.

Tuberculous empyema in lung transplantation recipients is a rare entity, with only a handful of cases reported in the English-language literature. We are reporting a case of tuberculous empyema 3 months after uncomplicated bilateral lung transplantation. The recipient underwent video-assisted thoracic surgery for diagnosis and decortication. Both the recipient and donor lacked a history of tuberculosis or tuberculosis exposure.

[Tuberculous pyopneumothorax: about 18 cases]. / Pyo-pneumothorax tuberculeux: à propos de 18 cas.

Tuberculous pyopneumothorax is a rare but serious complication of evolutive pulmonary tuberculosis. We report a series of 18 cases with tuberculous pyopneumothorax admitted to the Pneumo-Phthisiology Department of the Mohammed V Military Teaching Hospital in Rabat between January 2005 and December 2009. Our study included 15 men and 3 women, the average age was 35 ± 7 years. 4 patients were diabetic. Smoking was found in 9 cases. Right-sided pneumothorax was found in 13 cases. Chest radiograph showed cavitary lesions in 15 patients and extensive bilateral lesions in 8 cases. The search for Mycobacterium tuberculosis in the fluid from the gastric tube was positive in 16 cases. Chest drainage associated with antituberculosis treatment according to the 2SRHZ/7RH regimen and respiratory kinesitherapy were performed in all cases. The average duration of pleural drainage was 4 weeks. In 3 cases we noted persistent pleural suppuration requiring pleural toilet using thoracoscopy with pleurectomy and limited pulmonary resection to eliminate tuberculous parenchymal lesions and the persistence of a large pleural pocket with restrictive ventilatory defect that required surgery for pleural decortication in two cases. The outcome was favorable with minimal pachypleuritis as sequelae in the remaining cases. Tuberculous pyopneumothorax is a severe form, which is often associated with active cavitary tuberculosis. Evolution is generally progressive despite antituberculosis treatment and thoracic drainage, hence the need for early diagnosis and treatment of all forms of tuberculosis.

Spontaneous haemoptysis as a late complication of plombage in a tuberculosis patient.

The endemic spread of tuberculosis after World War II and the deficiency of appropriate antituberculous drugs had led to a renaissance of the surgical tuberculosis therapy until the early 1950s. Late complications of plombage performed decades before are rare and are mainly related to infection and/or migration of the inserted foreign material and are scarcely recognized today. We report on a 73-year-old male patient, who was admitted to the emergency room of our hospital with acute massive haemoptysis for four days. On physical examination the patient presented with decreased breath sounds over the left lung and an old left-sided thoracotomy scar. Radiological findings and bronchoscopy revealed an empyema and a fistula as late complications 53 years after collapse therapy with insertion of a plombage for the treatment of pulmonary tuberculosis. The endobronchial nylon threads in the left bronchial tree and the fistula ending in the left lower bronchus confirmed our diagnosis. The patient was successfully treated by resection of the affected lower lobe. The present casuistic demonstrates a rare cause of spontaneous haemoptysis: late complications after extrapleural pneumolysis and plombage for cavitary tuberculosis over 50 years after the initial operation.

[Application of early videothoracoscopic pulmonary decortication in the treatment of an acute pleural empyema and suppurated clotted hemothorax].

There was presented the experience of performance of videothoracoscopic pulmonary decortications in 22 patients, suffering suppurated clotted hemothorax, and in 188--an acute pleural empyema. In 97.3% patients the cessation of purulent process and pulmonary volume restoration were achieved. Residual cavities with the pulmonary nonairtightness signs were revealed in 3 (1.4%) patients, the empyema recurrence--in 1 (0.5%), suppuration of the wound, made by thoracic port--in 1 (0.5%), all the patients are alive.

[Use of endobronchial valve in postresection empyema and residual cavities with bronchopleural fistulas].

The results of treatment are analyzed in 78 patients with brochopleural fistilas after lung surgery. A method for imaging the draining bronchus under endoscopic guidance, by using the foamed dye administered into the residual cavity, has been developed. A valvular bronchial blocker for abolishing the function of bronchopleural fistular inserted into the lobular and segmental bronchus at bronchoscopy was designed and clinically tested. This procedure allows resurgery to be avoided in 91.7% of cases.

Tuberculose pleural / Tuberculous pleural effusions

O derrame pleural tuberculoso pode ser devido a uma manifestação da forma primária da doença ou da reativação de uma infecção latente pelo M. tuberculosis. Os avanços nos métodos laboratoriais contribuíram sobremaneira para um melhor diagnóstico e para a compreensão da fisiopatologia desta doença. No entanto, embora o derrame pleural predominante linfocítico seja indicativo de tuberculose em nosso meio, uma rotina de abordagem diagnóstica deve ser instituída a fim de orientar o tratamento precoce e evitar seqüelas.

Tuberculous pleural effusion is a common manifestation of the primary form of the disease or consequence of the reactivation of a latent infection due to the M. tuberculosis. Advances in the laboratory methods have contributed to better diagnose and understand the pathophysiology of the effusion secondary to tuberculosis. However, although a predominant lymphocytic pleural effusion is suspicious of tuberculosis, a diagnostic routine shall be instituted to orient treatment and prevent undesirable sequels.

[The efficiency of complex treatment of tuberculous spontaneous pneumothorax and its complications].

The incidence of spontaneous pneumothorax and pleural empyema and the outcomes of their medical and surgical treatments in 1982 to 2003 were studied in 541 patients with destructive pulmonary tuberculosis. In the past decade, the incidence of spontaneous pneumothorax and pleural pneumonia has increased from 2.6 to 12.1% due to the aggravated epidemic situation and the worse structure of pulmonary tuberculosis. The clinical severity of the disease and the extent of a pulmonary-and-pleural process did not allow radical reparative operations to be performed in 11.3%. Complex medical and surgical treatment for pulmonary tuberculosis complicated by spontaneous pneumothorax and pleural empyema could yield good and fair results in 71.5% of patients with severe pulmonary-and-pleural comorbidity despite high hospital mortality (17.2%).

[Surgical approach to lung tuberculosis]. / Plauciu tuberkuliozes chirurginio gydymo principai.

The article describes treatment results of 1228 patients operated on because of different forms of pulmonary tuberculosis. According to spreading of tuberculosis and developed complications in spite of the medicamental treatment the patients were divided in to two clinical groups. The first group included 417 patients with direct indications for surgery. The second group included 811 patients with complications of pulmonary tuberculosis (with spontaneous pneumothorax - 237, spontaneous pyopneumothorax - 170, tuberculous pleural empyema - 271, pulmonary hemorrhage - 105, with pulmonary reoperations - 28). The results of radical and paliative operations were as follows: 1176 (95.8%) patients recovered, and 52 patients (4.2%) died. CONCLUSION. When therapical treatment of pulmonary tuberculosis is ineffective, especially in drug resistant cases, the surgical treatment is indicated.

Miliary tuberculosis as a cause of acute empyema.

Adult respiratory distress syndrome (ARDS) and sepsis are known, life-threatening complications of miliary tuberculosis. This report describes a patient with miliary tuberculosis who rapidly developed an acute tuberculous empyema. She had a fulminant course culminating in ARDS, sepsis and subsequent death. This case highlights the rare association of acute empyema with miliary tuberculosis.

A case of pyothorax-associated lymphoma simulating empyema necessitatis.

We describe a case of a diabetic man with a 40-year history of chronic tuberculous empyema presented with fever, chest pain and bulging soft tissue of the right chest wall. CT scan revealed a huge chest wall mass showing extensive necrosis with air-bubbles and destruction of the ribs. Decortication and extirpation of the chest wall mass were performed, and histopathologic examination confirmed diffused large cell type non-Hodgkin's lymphoma.

[Risk of increase in nosocomial infections incidence in a surgical clinic. A case-control study]. / Riscul cresterii incidentei infectiilor nosocomiale într-un serviciu de chirurgie. Studiu caz-control.

The complex activities of epidemiological surveillance of nosocomial infections (NI) have, among the main objectives, the identification of the causes and the assessment of risk factors. In 2002, the Clinic Hospital of Pneumology Iasi had 220 beds and was divided into the following units: Pneumophtisiology Unit (PPU), Thoracic Surgery Unit (TSU) and Intensive Care Unit (ICU). The global incidence of NI was of 0.85%. The incidence of cases with NI in the TSU and ICU increased to 5.39% in the interval April-June 2002 so that urgent epidemiological measures were applied to limit the phenomenon. After that, a case-control study was proposed in order to identify and assess the risk levels. The retrospective study met the methodological conditions such as case definitions for NI and post-surgical NI, for extrinsic and intrinsic risk factors, the selection of cases according to inclusion and exclusion criteria, the formation of the representative sample. The study included 16 patients with pleural NI and 55 controls with the pleurotomy performed between April-June in the TCU, as a common feature. The factors that increased the probability of a post-surgical NI development were: the external pleural drainage maintained more than 30 days (OR = 185.5; p < 0.0001 for CI = 95%), tuberculosis as the most important associated disease among the patients' pathological history records (OR = 28.0; p < 0.0001; CI = 95%); the antibiotherapy with multiple associations (OR = 3.30; p < 0.04; CI = 95%). The conclusions underlined that the patients suffered from tuberculosis since the very admission, which need pleurotomy have an increased risk to develop a NI. This fact should require an appropriate epidemiological, clinical and microbiological surveillance and the empirical antibiotic strategy or that conducted by the antibiogram results has to be performed adequately, according to the operative recommendations.

[Extensive selective thoracostomy in the treatment of pleural empyema]. / Rasshirennaia selektivnaia torakostomiia v lechenii émpiemy plevry.

Fifty-seven patients with disseminated bilateral destructive pulmonary tuberculosis complicated by empyema were followed up. Treatment included laser radiation at wavelengths of 0.69 and 0.43 micron, which can enhance therapeutical efficiency on an average of 37.5% and reduce preoperative preparation by 1.7 times. The procedure of selective extended thoracostomy expanded indications for surgery in critically ill patients with destructive pulmonary tuberculosis by reducing the surgical risk by several times.

[Primary pleural lymphoma after collapse therapy: modern aspects of an historic disease]. / Lymphomes pleuraux primitifs après collapsothérapie: aspects modernes d'une maladie historique.

INTRODUCTION: Pleural lymphomas after long standing pyothorax due to pulmonary tuberculosis are now well identified. Most cases have been described by Japanese investigators and it seems rare or unrecognised in Western countries. We report the study of six cases observed in a single institution. PATIENTS AND METHODS: Six pyothorax-associated pleural lymphomas, among 1,038 lymphoma (0.6%) collected during a period from 1989 to 1998, are described. Diagnosis was established by two pathologists with the usual histologic and immunohistochemical methods, according to the working formulation. The in situ hybridization method for Epstein-Barr virus was performed. RESULTS: The average age of the patient was 73 years. Presenting symptoms combined chest pain and constitutional symptoms more than 45 years after artificial pneumothorax or tuberculous pleuritis. Computerized tomography revealed a pleural mass which involved the adjacent chest wall. Open biopsy by thoracotomy show a diffuse B-cell non-Hodgkin-lymphoma in all cases. Though the lymphoma was initially localized, many poor prognostic factors (age, performance status, LDH, histology) explain the pejorative evolution (average survival of five months). Patients died from an uncontrolled tumoral proliferation or by infectious complications. In situ hybridization confirms the presence of Epstein-Barr virus in tumoral cells. CONCLUSION: Pleural lymphoma is an established complication of artificial pneumothorax. Even if the Epstein-Barr virus plays a crucial role in the pathogenesis, and despite the number of artificial pneumothorax operations that have been widely performed, this lymphoma remains rare, suggesting additional oncogenic factors.

Pleural tuberculosis.

Tuberculous pleural effusions occur in up to 30% of patients with tuberculosis. It appears that the percentage of patients with pleural effusion is comparable in human immunodeficiency virus (HIV)-positive and HIV-negative individuals, although there is some evidence that HIV-positive patients with CD4+ counts <200 cells x mL(-1) are less likely to have a tuberculous pleural effusion. There has recently been a considerable amount of research dealing with the immunology of tuberculous pleurisy. At present, we have more evidence that activated cells produce cytokines in a complex pleural response to mycobacteria. Intramacrophage elimination of mycobacterial antigens, granuloma formation, direct neutralization of mycobacteria and fibrosis are the main facets of this reaction. With respect to diagnosis, adenosine deaminase and interferon gamma in pleural fluid have proved to be useful tests. Detection of mycobacterial deoxyribonucleic acid (DNA) by the polymerase chain reaction is an interesting test, but its usefulness in the diagnosis of tuberculous pleurisy needs further confirmation. The recommended treatment for tuberculous pleurisy is a 6 month regimen of isoniazid and rifampicin, with the addition of pyrazinamide in the first 2 months. HIV patients may require a longer treatment. The general use of corticosteroids is not recommended at this time, but they can be used in individuals who are markedly symptomatic.

Primary Epstein-Barr virus-related non-Hodgkin's lymphoma of the pleural cavity following long-standing tuberculous empyema.

Primary non-Hodgkin's lymphomas of the pleural cavity have been described mostly in Japan. We report a case of high-grade non-Hodgkin's lymphoma (immunoblastic type) of the pleural cavity occurring in a nonimmunocompromised patient 55 years after an artificial pneumothorax was performed for the treatment of pulmonary tuberculosis. Immunohistochemical study revealed a B phenotype (CD20), and an in situ hybridization detected small nuclear RNAs encoded by Epstein-Barr virus in most lymphomatous cells. A link between primary pleural lymphoma and the local long-standing chronic inflammation, inducing a clonal transformation of Epstein-Barr virus-infected immortalized B lymphocytes, is suspected.

The etiology of pleural effusions in an area with high incidence of tuberculosis.

To investigate the etiology of pleural effusions in our region, we undertook a prospective study of patients with this condition in our centers. During a 5-year period, we studied 642 pleural effusion patients aged 57.1 +/- 21.1 years, of whom 401 were men aged 56.5 +/- 21 years and 241 were women aged 57.8 +/- 21.4 years; the male/female ratio was 1.6:1. The most frequent cause of pleural effusion was tuberculosis (25%), followed by neoplasia (22.9%) and congestive heart failure (17.9%). The etiology of 48 cases (7.5%) remained uncertain. In the neoplastic effusion group, the most frequent locations of the primary tumor were lung (32.6%), breast (11.5%), lymphoma (10.8%), and ovary (7.5%); in 21 cases (14.3% of the neoplastic group), it was not possible to identify the primary tumor. The 111 patients aged younger than 40 years with tuberculous effusions made up 69.4% of tuberculous effusion cases and the same percentage of patients younger than 40 years; the proportion of effusions that were tuberculous peaked in the 11- to 30-year-old age group and declined steadily thereafter. Of the patients with neoplastic effusions, 83% were older than 50 years; the proportion of effusions that were neoplastic rose steadily from zero in the 0- to 30-year-old age group to a peak among 60- to 70-year-olds. The age-wise distribution of effusions secondary to congestive heart failure was similar to that of neoplastic effusions. Of the effusions secondary to congestive heart failure, 86% (99/115) affected the right pleura or both, and 83% of effusions secondary to pulmonary thromboembolism (15/18) affected the right side. Neoplastic, tuberculous, parapneumonic, empyematous, and other exudative effusions showed no preference for either side. Of the 97 bilateral effusions, 77 (79.4%) were secondary to heart failure (59, 60.8%) or neoplasia (18, 18.6%). We conclude that in our region, the most frequent cause of pleural effusion is tuberculosis, followed by neoplasia and congestive heart failure. We suggest that all those interested in pleural disease should determine the etiologic pattern of pleural effusion in their region with a view to the adoption of regionally optimized diagnostic and therapeutic attitudes.

Interleukin-1 beta in pleural fluids of different etiologies. Its role as inflammatory mediator in empyema.

STUDY OBJECTIVES: To measure interleukin-1 beta (IL-1 beta) levels in pleural effusions of different etiologies and their relationship with several pleural inflammatory parameters, and to verify whether IL-1 beta can be used as diagnostic marker in the differential diagnosis of pleural diseases. MATERIAL AND METHOD: One hundred two pleural effusions were analyzed using a monoclonal antibody enzyme-linked immunosorbent assay. Pleural fluids were classified as follows: transudates (n = 28), empyema (n = 14), parapneumonic (n = 13), tuberculous (n = 19), neoplastic (n = 17), and miscellaneous effusions (n = 11). RESULTS: IL-1 beta was above 200 pg/mL in all the patients with empyema but only in three patients with other etiologies. Two of those three had parapneumonic effusions and the remaining one had a tuberculous pleurisy with a previous bacterial empyema. No significant relationships were found between pleural effusion IL-1 beta levels and the different inflammatory parameters analyzed. As a diagnostic criterion for empyema, pleural IL-1 beta concentration greater than 200 pg/mL had a sensitivity of 100%, a specificity of 96%, and a positive and negative predictive value of 0.82 and 1, respectively. CONCLUSIONS: Our data suggest that IL-1 beta has a significant role in pyogenic infections of the pleural space but not in effusions of other etiologies. It could be used as a diagnostic marker of empyema.
