Intrathoracic negative pressure therapy and/or endobronchial valve for pleural empyema minimal invasive management: case series of thirteen patients and review of the literature

Empyema in children

Empyema is the infection of the fluid in the pleural space due to different causes. The most common cause of empyema in children is parapneumonic effusion. Although its frequency has decreased significantly with the use of antibiotics, it is still a significant cause of morbidity and mortality worldwide. The main aim in the treatment of empyema is to drain the pleural cavity to provide reexpansion of the compressed lung, to treat the parenchymal infection with appropriate antibiotic therapy, and to prevent complications that may develop in the acute and chronic periods. Treatment options for this disease vary depending on the stage of the disease. Treatment success in childhood empyema detected at an early stage is high. The diagnosis and treatment of empyema in children differs from adults. Due to rapid tissue regeneration in childhood, healing can occur without the need for aggressive treatment options.

Can intrapleural alteplase treatment be an alternative to videothoracoscopic deloculation and decortication in pleural empyema?

Introduction

Chest tube drainage is the first step in the management of complicated pleural effusions that have turned into empyema. In cases where adequate drainage cannot be provided or deloculation is required, intrapleural fibrinolytic therapy or surgical deloculation can be performed. Alteplase is a suitable agent for intrapleural fibrinolytic therapy. On the other hand, video-assisted surgery is an effective and minimally invasive treatment option for lung re-expansion.

Aim

The effect of intrapleural alteplase irrigation applied through the thoracic tube in the treatment of pleural empyema was investigated and whether it could be an alternative technique to video-assisted thoracoscopic surgery was evaluated.

Material and methods

The results of patients who were treated for empyema in our clinic were evaluated retrospectively. Twenty-one patients who underwent tube thoracostomy + intrapleural alteplase and 28 patients who underwent VATS deloculation were included in the study.

Results

The study included 35 male and 14 female patients. There were 21 patients in group 1, and 28 patients in group 2. The mean age was 50.6. The average length of thoracic tube stay was determined as 7.1 and 6.96 days. The duration of hospital stay in this group was 6.73 and 6.35 days. In 17 (81%) patients in group 1, the treatment was discontinued without the need for surgery.

Conclusions

VATS-D is an effective option in the treatment of pleural empyema. However, as seen in our study, intrapleural alteplase application is at least as effective as VATS-D in terms of treatment success.

Pleural empyema in children - benefits of primary thoracoscopic treatment

Introduction

Pleural empyema is the condition of the pleural cavity when initially sterile pleural effusion has become infected. In the majority of cases, it is of parapneumonic origin. Parapneumonic effusions and pleural empyemata usually continuously progress in severity. The American Thoracic Society divides them into three stages: exudative, fibrinopurulent and organizing. The therapy depends on the stage.

Aim

To assess whether thoracoscopy should be considered better than conservative treatment and to assess the feasibility of the thoracoscopic approach to the 3^rd phase of pleural empyema.

Material and methods

The clinical course of 115 patients treated from 1996 to 2017 was analyzed. 45 patients operated on thoracoscopically after the failure of conventional treatment were compared with 70 patients treated by primary thoracoscopic drainage and decortication.

Results

The results of the study demonstrated that patients treated primarily by thoracoscopy had a shortened length of hospital stay (16.6 vs. 19.3 days), reduced drainage time (7.9 vs. 9.8 days), and shorter time of general therapy (31.8 vs. 38.0 days). They required fibrinolysis less frequently (12.8 vs. 26.7% of patients) and had reduced risk of reoperation (10 vs. 15.6% of cases). Operation time in the 3^rd stage was only 15 min longer. The difference in length of hospital stay was only 0.8 days in favor of less severe cases.

Conclusions

The thoracoscopic approach is safely feasible in the 3^rd stage of pleural empyema and should be considered as the preferred approach. Furthermore, the post-operative stay and general course of the disease are milder whenever surgery would not be delayed by prolonged conservative treatment attempts.
