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.

Empyema necessitans: very late complication of pulmonary tuberculosis.

Empyema necessitans is a rare clinical finding nowadays. We report the case of a patient admitted in our ward for investigation of an unknown onset anterior chest wall mass, with no accompanying signs or symptoms. It is noteworthy that the patient had had pulmonary tuberculosis submitted to thoracoplasty more than 60 years before. Thoracic MRI showed a large heterogeneous mass, with a thick wall and internal septations located at the right anterior chest wall, as well as a heterogeneous content inside the right pleural cavity, with direct communication between both. An aspirative puncture of both masses was performed, with positive cultures for Mycobacterium tuberculosis, thus leading to the diagnosis of pleural tuberculosis with anterior chest wall empyema necessitans. A drain was inserted and antibiotics started. This case draws our attention to a very rare complication of pulmonary tuberculosis and its surgical treatment, though it aroused many decades after primary infection.

Intrathoracic muscular transposition in chronic tuberculous empyema.

BACKGROUND: The effective management of chronic tuberculous empyema requires an evacuation of pus and a re-expansion of the lung or an obliteration of the empyema space such as closed thoracostomy, decortication, or open window thoracostomy (OWT) followed by intrathoracic muscular transposition (IMT). However, the most effective management of chronic tuberculous empyema is still debatable. METHODS: From June 1999 to July 2010, 18 patients with chronic tuberculous empyema who underwent OWT and/or IMT were enrolled in this study. The causes of empyema, and methods and outcomes of treatment were retrospectively reviewed. The success rate of IMT was investigated to evaluate the efficacy. RESULTS: Mean patient age was 54.3 ± 14.9 years and 16 patients were male. Depending on operative methods, three groups were divided: OWT only (n = 4); two-stage operation as OWT followed by IMT (n = 7); and one-stage operation as OWT with IMT simultaneously (n = 7). Of 14 patients who underwent IMT, 13 patients successfully recovered from empyema and bronchopleural fistula (BPF) (success rate, 92.86%), but one patient developed a secondary bacterial infection. There was no operative mortality. CONCLUSION: This study suggests that IMT may be an effective option to control infection or BPF in chronic tuberculous empyema.

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.

[The surgical treatment of chronic tuberculous empyema of the pleura].

333 patients with chronic tuberculous empyema were treated in the Central Military Clinical Tuberculous Hospital N 4. Among them there were 325 (97,6%) men and 8 (2,4%) women. The patients' age varied from 18 to 87 years. The main causes of empyema development were the following: the exudative pleurisy--in 179 (53,8%) cases, the complications of lung resection--in 69 (20,7%), the ineffective artificial pneumothorax--in 50 (15,0). In 34 (10,2%) patients the empyema was the result of spontaneous pneumothorax and in 1 (0,3%) patient it developed due to generalization of tuberculosis of extra-pulmonary localization. The treatment was based on extensive surgical interventions performed in patients during the stable and subacute phases of pathologic process. It allowed achieving the good results in 89,2% and satisfactory results--in 9,9% patients.

Clinical characteristics and outcomes of empyema thoracis in 117 patients: a comparative analysis of tuberculous vs. non-tuberculous aetiologies.

BACKGROUND: Empyema thoracis remains a major problem in developing countries. Clinical outcomes in tuberculous empyema are generally believed to be worse than in non-tuberculous aetiologies because of the presence of concomitant fibrocavitary parenchymal disease, frequent bronchopleural fistulae and poor general condition of patients. We performed a prospective study over a 2-year period with the objective of comparing the clinical characteristics and outcomes of patients with tuberculous vs. non-tuberculous empyema. METHODS: Prospective study of all cases of non-surgical thoracic empyema seen at a tertiary care centre in North India over a 2-year period. A comparative analysis of clinical characteristics, treatment modalities and outcomes of patients with tuberculous vs. non-tuberculous empyema was carried out. Factors associated with poor outcomes were analysed using multivariate logistic regression. RESULTS: One hundred and seventeen cases of empyema were seen in the study period of which 95 had non-tuberculous and 41 had tuberculous empyema. Malnutrition and bronchopleural fistulae (BPF) were more common and duration of symptoms longer in the tuberculous empyema group. Time to resolution of fever, duration of pleural drainage and pleural thickening >2 cm were significantly greater as well. Eight (10.5%) patients with non-tuberculous empyema and four (9.8%) with tuberculous empyema succumbed. Presence of a BPF was significantly associated with poor outcomes on multivariate logistic regression analysis. CONCLUSIONS: Tuberculous empyema remains a common cause of thoracic empyema in India though it ranked second amongst all causes of empyema after community acquired lung infections in this study. Tuberculous empyema is associated with longer duration of symptoms, greater duration of pleural drainage and more residual pleural fibrosis.

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.

Modern epidemiologic data about prevalence and etiology of the nonspecific pleural exudates syndrome were suggested in patients of phthisio-pulmonary specialty, and also its dynamic during last 7 years. The main trends of change of frequency of the different etiology pleural exudates occurrence taking into account the patients gender were determined. The most wide spread forms of pleural exudates: parapneumonic, purulent, reactive, phthisic, cardiogenic were detailed.

[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.
