AIM: To explore the factors that influence sample adequacy and safety of ultrasound (US)-guided biopsy for peripheral pulmonary lesions (PPLs) with 16-G needles.
MATERIALS AND METHODS: A total of 263 patients (150 men, 113 women; mean age, 60.7 ± 13 years) who received US-guided biopsy for PPLs with 16-G needles from July 2017 to March 2021 were included. Variables including patient demographics, lesion location, lesion size, proportion of lesion necrosis, presence of emphysema, presence of bullae around lesion, patient position, and number of needle passes were recorded. Univariate analysis and multivariable logistic regression analysis were performed to explore the factors that influence sample adequacy and safety.
RESULTS: Biopsy specimens were adequate for diagnosis in 242/263 (92%) cases. Multivariable logistic regression analysis revealed lesion size was significantly associated with sample adequacy (p=0.005, odds ratio [OR] = 1.039). The incidence of overall complication rate was 10.6% (28/263), including pneumothorax and haemorrhage, which occurred in 2.7% (7/263) and 9.9% (26/263) of patients, respectively. Patient position (lateral versus supine) was associated with overall complication rates (p=0.029, OR=3.407) and haemorrhage (p=0.013, OR=4.870). The presence of bullae around the lesion (p=0.026, OR=73.128) was an independent factor associated with pneumothorax.
CONCLUSION: US-guided percutaneous biopsy for PPLs with 16-G needles is effective and safe. Sample adequacy is significantly affected by lesion size. Patient lateral position is a risk factor for overall complication and haemorrhage. The presence of bullae around the lesion is a predictor of pneumothorax.
