Background: Increasing success rate and reducing complications are important for computed tomography (CT)-guided percutaneous core needle biopsy (PCNB). Objectives: To assess the influence of needle angle and lesion depth on procedural success and complications of CT-guided PCNB for intrapulmonary lesions, performed by a single radiologist. Patients and Methods: A total of 689 cases of PCNB performed under CT guidance were enrolled in this study. The collected data were retrospectively reviewed. The pathologic results and complications were evaluated for each case. Two factors-needle angle and lesion depth-were statistically analyzed to assess the relationship with procedural success and complications of PCNB by using univariate analysis. Post hoc analysis was performed with Bonferroni’s method. Results: The overall success rate was 93.1% (642/689). Procedural success showed no statistically significant association with both needle angle (P = 0.568) and lesion depth (P = 0.144). The overall complication rate was 17.9% (123/689) with 15.7% for minor complications and 2.2% for major complications. The needle angle had no association with complications (P = 0.101). Presence and severity of complications showed a direct relationship with lesion depth (P < 0.01). In fact, more severe complications occurred in deeper located lesions. Conclusion: Needle angle had no effect on both procedural success and complications. Also, there was no significant correlation between lesion depth and procedural success. However, lesion depth was closely correlated with the incidence and severity of complications after PCNB.

Abstract Background We aim to analyze the risk factors for pneumothorax associated with computed tomography (CT)-guided percutaneous core needle biopsy (PCNB) of the lung. Whether the lung function characteristics are related to pneumothorax is unclear. Methods We retrospectively evaluated 343 patients who received CT-guided pulmonary PCNBs and underwent preoperative pulmonary function testing. Demographical, lesion-related, procedure-related features and histopathological diagnosis, as well as results of pulmonary function test were analyzed as risk factors of pneumothorax Results Variables associated with higher rate of pneumothorax were location of lesion, presence of emphysema, and dwell time. The proportion of middle lobe, lingular, or lower lobe lesions in pneumothorax group (30/50, 60.0%) is higher than non-pneumothorax group (113/293, 38.6%). The incidence of emphysema in pneumothorax group was significantly higher than that in non-pneumothorax group (34.0% vs. 7.5%). Obstructive pulmonary function abnormalities, not restrictive, mixed ventilation function abnormalities and small airway dysfunction, correlated with pneumothorax. Multivariate logistic regression analysis showed lower location of lesion sampled and presence of emphysema were independent predictors of pneumothorax. Although dwell time, FEV1/FVC ratio, FEF50%, FEF75% and FEF25–75% were significantly correlated with pneumothorax on univariate analysis, these were not confirmed to be independent predictors. Conclusions Patients with obstructive pulmonary dysfunction have a higher risk of pneumothorax. Presence of emphysema was the most important predictor of pneumothorax, followed by location of lesion.

Abstract Background and Objective: Computed tomography guided percutaneous lung biopsy is a commonly used method for clarifying the nature of pulmonary nodules. However, due to the existence of breathing movement, the lungs have greater mobility, and biopsy of small pulmonary nodules is difficult. In recent years, 3D-printed coplanar templates are gradually used in percutaneous biopsy of small pulmonary nodules. Therefore, this study aimed to evaluate the application value of 3D-printed coplanar puncture template assisted computed tomography guided percutaneous core needle biopsy of small (≤20mm) pulmonary nodules.Method: From January 2018 to January 2021 in Taihe Hospital, 210 hospitalized patients with pulmonary nodules underwent percutaneous core needle biopsy for histopathology/cytopathology diagnosis and were included in the study. All patients were allocated into two groups, patients in Free-hand group underwent percutaneous core needle biopsy without 3D-printed coplanar templates, and patients in 3D-PCT group underwent percutaneous core needle biopsy with 3D-printed coplanar templates. The number of needle adjustments, number of CT scans, surgical time-consuming, diagnostic accuracy, and incidence of complications were recorded and compared between the two groups. Rapid on site evaluation was routinely used for guiding specimens’ triage. Approval for this trial was obtained from the Ethics Committee of the Taihe hospital.Result：The number of needle adjustments (1.41±0.63 vs. 2.23±0.85), the number of CT scans (3.63±0.73 vs. 4.25±0.81) and the incidence of pneumothorax (9.6% vs. 21.1%) during the procedure were significantly lower in the observation group than the control group (P< 0.05), whereas there were no significant differences in the diagnostic accuracy (95.2% vs. 94.3%) and incidence of pulmonary hemorrhage (65.4% vs. 62.3%) between the two groups (P> 0.05), however, the surgical time-consuming in 3D-PCT group is significantly more than Free-hand group.Conclusions: These findings indicated that the 3D-printed coplanar puncture template combined with CT guided percutaneous biopsy can relatively fix the target lesion, reduce the number of needle adjustments and number of CT scans, reduce iatrogenic radiation, and reduce the incidence of complications, especially pneumothorax

Background: Early diagnosis of lung cancer can reduce its mortality and morbidity. Minimally invasive image guided percutaneous core needle biopsy can obtain tissue sample for diagnosis and staging of lung cancer, which is crucial for correct management of lung lesions. Common complications of lung biopsy include pneumothorax, parenchymal haemorrhage and haemoptysis. The study was aimed to determine diagnostic yield and complications of the percutaneous computed tomography (CT) guided core needle biopsy of lung lesion in tertiary hospital.Methods: Hospital based prospective study was performed in 40 patients in Tribhuvan University Teaching Hospital. CT guided biopsy of lung lesions was performed with 18-gauge semi-automated biopsy instrument. The complications following the biopsy were recorded and correlated with different factors using chi-square test. Histopathology report were obtained to measure the diagnostic yield.Results: Among 40 patients who underwent guided lung biopsy, histopathology showed definitive diagnosis in 37 patients; 31 malignant and 6 benign lesions. Parenchymal haemorrhage, pneumothorax and haemoptysis were seen in 13, 8 and 5 respectively; however, none required active intervention. Emphysema in traversing lung and numbers of pleural punctures used were predictive factors of complication (p value <0.05).Conclusions: The study showed percutaneous image guided core needle biopsy has high diagnostic yield with fewer complication rates and is thus recommended for routine biopsies of lung lesions.
