Percutaneous management of parapneumonic effusions

Percutaneous management of complicated parapneumonic effusion and empyema after surgical tube thoracostomy failure in children: a retrospective study

PURPOSE

We aimed to evaluate the results of percutaneous management of complicated parapneumonic effusions (PPE) and empyema after surgical tube thoracostomy failure in children.

METHODS

A total of 84 children treated percutaneously after surgical tube thoracostomy failure between 2004 and 2019 were included to this retrospective study. Technical success was defined as appropriate placement of the drainage catheter. Clinical success was defined as complete resolution of infection both clinically and radiologically. Management protocol included imaging-guided pigtail catheter insertion, fibrinolytic therapy, serial ultrasonographic evaluation, catheter manipulations as necessary (revision, exchange, or upsizing), and appropriate antibiotherapy. All patients were followed up at least 6 months.

RESULTS

Technical success rate was 100%. Unilateral single, unilateral double, and bilateral catheter insertions were performed in 73, 9, and 2 patients, respectively. Inserted catheter sizes ranged from 8 F to 16 F. Streptokinase, urokinase, and tissue plasminogen activator were used as fibrinolytic agent in 29 (34%), 14 (17%), and 41 (49%) patients, respectively. In order to maintain effective drainage, 42 additional procedures (catheter exchange, revision, reposition, or additional catheter placement) were performed in 20 patients (24%). Clinical success was achieved in 83 of 84 patients (99%). Median catheter duration was 8 days (4-32 days). Median hospital stay during percutaneous management was 11.5 days (7-45 days). Factors affecting the median catheter duration were the presence of necrotizing pneumonia (p < 0.001) and bronchopleural fistulae (p < 0.001).

CONCLUSION

Percutaneous imaging-guided catheterization with fibrinolytic therapy should be the method of choice in pediatric complicated PPE and empyema patients with surgical tube thoracostomy failure. Percutaneous treatment is useful in avoiding more aggressive surgical options.

Two-Year Experience of 14 French Pigtail Catheters Placed by Procedure-Focused Hospitalists

BACKGROUND

Recent studies show small-bore chest tubes, commonly 14 French pigtail catheters (PCs), are noninferior to large-bore chest tubes for treating various conditions, and they are associated with better patient comfort. The Medical College of Wisconsin implemented a bedside procedure service (BPS) that has been trained in the placement of PCs as an adjunct to its interventional radiology department.

METHODS

The data regarding consults for PC placement was collected by the BPS over a 2-year period. Primary outcomes reviewed were insertion-related complications (IRCs), unsuccessful attempts (UAs), and adverse outcomes (AOs) because the authors believe these represent the safety and effectiveness of the group. It was determined which services consulted the BPS for PC placement, the indications for consults, and a brief review of declined PC consults.

RESULTS

Of the 124 accepted consults, the service had 3 IRCs (2.4%), 2 UAs (1.6%), and 3 AOs (2.4%). A total of 18 consults were declined. The BPS was consulted by 12 services with 8 primary reasons for PC placement.

CONCLUSIONS

At high-volume, tertiary care centers, and with the support of cardiothoracic surgical and interventional radiology services, procedure-focused hospitalists can safely serve as an adjunct service for PC placement in selected hospitalized patients.
