Pneumothorax After VATS for Pleural Empyema in Pediatric Patients.

(1)

Background

In children, bacterial pneumonia is the most common cause of parapneumonic pleural effusions which can eventually lead to pleural empyema. Treatment is varied and is a combination of antibiotic therapy, chest tube drainage, fibrinolytics and video-assisted thoracoscopic surgery (VATS). Postoperative complications of the latter include pneumothoraces and bronchopleural fistula (BPF). The aim of this study is to investigate the incidence and duration of pneumothoraces during the perioperative period and follow-up (FU) to elucidate their progression following video-assisted thoracoscopic surgery (VATS) to start to create an evidence-based standardized FU protocol.

Methods

This retrospective study included all patients who underwent VATS for pleural empyema between January 2013-May 2023 at the University Medical Center Hamburg-Eppendorf (UKE) and the Hamburg Children's Hospital Altona (AKK). (3)

Results

We identified 47 patients with pleural empyema who underwent VATS. A proportion of 43% of patients were found to have a pneumothorax with 55% of those being unresolved at discharge. At the end of FU, 27% of those had a "pneumothorax ex vacuo". No surgical interventions were needed. (4)

Conclusions

The majority of pneumothoraces after VATS in pediatric patients can be managed conservatively. In the context of follow-up care, it is recommended that X-ray examinations should be used sparingly, while sonographic follow-up examinations should be conducted more frequently. If the pneumothorax persists, further thoracoscopy for resection of the visceral pleura and treatment of bronchopleural fistula may be the next step in treatment.
