AI Article Synopsis
- The study evaluated the coaxial (CX) technique for CT-guided lung percutaneous needle biopsy (PNB) over a 7-year period involving 700 patients to determine its diagnostic effectiveness and complications.
- The CX technique showed a high diagnostic accuracy of 93%, enabling the collection of multiple tissue specimens from a single puncture, but had a notable incidence of pulmonary hemorrhage (55.4%) and pneumothorax (42.9%).
- Overall, the study concluded that the CX technique is highly effective for lung biopsies while identifying factors to enhance diagnostic outcomes and reduce complications.
Article Abstract
Background/aim: Lung percutaneous needle biopsy (PNB) under CT guidance can be performed with a single-needle or with a coaxial (CX) technique. This study evaluated the CX technique in a large cohort of patients who underwent to CT-guided lung PNB in our Institute over a period of 7 years.
Patients And Methods: We retrospectively collected and analyzed data relative to 700 CT-guided lung PNBs performed from August 2012 to August 2019 in 700 patients (M:F=436:264; mean age=69 years, range=6-93 years) with normal coagulation and pulmonary function. PNB was considered diagnostic if at least one of the collected tissue specimens allowed for histological diagnosis. Pulmonary hemorrhage (PH) and pneumothorax (PNX) were evaluated as present or absent. Statistical analysis was made by Chi-square test of Pearson, Fisher's exact test and Wilcoxon test.
Results: The CX technique showed a high diagnostic accuracy (93.0%) and allowed the collection of a great number of appropriate tissue specimens with a single pleural puncture (≥3 specimens in 77.4% of cases). PH was the complication more frequent (55.4%), without significant clinical impact. Global PNXs incidence was high (42.9%), but the introducer allowed to aspirate the PNX with a lower percentage of chest tube placement vs. PNXs not aspirated (6.3% and 13.3%, respectively).
Conclusion: This large retrospective study confirmed the high diagnostic accuracy of lung PNB with the CX technique and allowed identification of significant factors to achieve a greater diagnostic power and decrease complication rates.

Background: CT-guided percutaneous transthoracic needle biopsy is the primary method for diagnosing lung lesions. Widely accepted validated risk prediction models are yet to be developed. A recently published study conducted at Grampians Health Services (GHS) developed two risk prediction models for predicting pneumothorax and intercostal catheter (ICC) insertion.

Background: With advancements in imaging testing and surgical procedures, an increasing number of nodules with smaller diameters and deeper locations have been deemed suitable for surgical intervention. The preoperative localization of these nodules has become essential. In this retrospective single-center study, we aimed to compare the effectiveness and patient comfort associated with the use of a four-hook needle versus a hook-wire needle for preoperative localization.

Background: Pulmonary nodule ablation is an effective method for treating pulmonary nodules. This study is based on the traditional CT-guided percutaneous microwave ablation (MWA) of pulmonary nodules. By comparing laser guidance technology with freehand method, this study aims to explore the safety and efficacy and patients' pain scores of these two approaches.

Background: Patients with early-stage non-small cell lung cancer (NSCLC) who are intolerant to surgery have a poor prognosis. Microwave ablation is an effective treatment method. However, the density of the lesion may occasionally be similar to that of the ablation zone, thus rendering it difficult to identify the relative position of the lesion and ablation zone during ablation.

To determine the benefit of a FDG PET/CT scan prior to CT-guided lung biopsy on the rate of diagnosis, rate of complication, and the identification of potentially safer biopsy sites. This retrospective observational cross-sectional study evaluated consecutive adult patients who underwent CT-guided lung biopsy in 2020 or 2021 at 2 Canadian tertiary care hospitals. These patients were grouped into those that had PET/CT performed within 8 weeks prior to biopsy, within 8 weeks after biopsy, or no PET/CT scan within this time frame.
