CT-guided percutaneous lung biopsy in children

Computed tomography (CT)-guided percutaneous lung biopsy is a diagnostic tool used in adults, but its application in children remains less studied. Prior research has shown that open surgical biopsy is often used in pediatric thoracic cases, but it carries higher risks and longer recovery times. This gap motivated an investigation into the safety and diagnostic accuracy of CT-guided biopsy in children. The study aimed to address uncertainties about the feasibility of using this technique in a younger population. No prior work had resolved how small lesion sizes or pediatric anatomy might affect outcomes. The need to reduce surgical interventions in children drove the exploration of less invasive alternatives. This paper provides insights into a procedure that could shift clinical practice in pediatric thoracic diagnostics. The focus on both technical and clinical outcomes makes this work distinct from earlier studies.

The study aimed to describe the techniques and evaluate the outcomes of CT-guided percutaneous lung biopsy in children. The specific problem addressed was the lack of data on the safety and accuracy of this procedure in pediatric patients. The motivation stemmed from the need to avoid open surgical biopsy, which is more invasive and carries greater risks. The authors sought to determine whether CT-guided biopsy could serve as a reliable alternative in children. They also wanted to assess the impact of lesion size and biopsy type on diagnostic success. The study focused on patients referred for suspected malignancy or posttransplantation complications. By analyzing procedural data and outcomes, the researchers aimed to guide clinical decision-making in pediatric thoracic diagnostics. Their goal was to provide evidence supporting the use of minimally invasive techniques in this population.

The study involved 64 pediatric patients who underwent 75 CT-guided lung biopsies between April 1992 and June 2003. Data were collected prospectively from medical records, including patient history, anesthesia type, and procedural details. The researchers categorized biopsies as core or aspiration techniques and noted lesion size and number of passes. They reviewed admission status and procedural modifications. Diagnostic outcomes were assessed by analyzing medical records for final diagnoses and management changes. Immediate complications were recorded, including pneumothorax and bleeding. The study compared diagnostic success rates between core and aspiration biopsies. Lesion diameters were measured to evaluate their impact on biopsy effectiveness. The authors also examined the role of deep sedation in procedural success. Their approach combined clinical and technical data to evaluate the overall safety and diagnostic yield of the procedure.

Of the 75 biopsies, 64 (85%) provided diagnostic results, indicating a high success rate. Core biopsies were used in 56 cases, while aspiration biopsies occurred in 15 cases. Lesion diameters averaged 2.5 cm for core biopsies and 1.0 cm for aspiration biopsies. Deep sedation was used in 61 procedures (81%), which supported patient cooperation and procedural success. Only one major complication occurred—a tension pneumothorax requiring chest tube placement. No other significant complications were reported, suggesting the procedure is safe in children. The diagnostic yield was sufficient to influence patient management in most cases. Smaller lesion sizes did not prevent successful aspiration biopsies. The use of a coaxial core biopsy technique was most common. These findings suggest that CT-guided biopsy is a reliable alternative to open surgery in pediatric thoracic diagnostics.

The authors concluded that CT-guided percutaneous lung biopsy is a safe and accurate diagnostic procedure in children. The high diagnostic yield (85%) supports its use as an alternative to open surgical biopsy. The procedure was associated with minimal complications, with only one major event reported. The use of deep sedation and coaxial core biopsy techniques contributed to procedural success. The findings suggest that this method is effective even for smaller lesions. The impact on patient management was significant in most cases. The authors emphasized that this technique obviates the need for more invasive procedures in most pediatric patients. Their results suggest that CT-guided biopsy is a viable option for diagnosing thoracic lesions in children.
