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.

Background: CT guided core needle biopsy is a less invasive method for initial diagnostic workup in the assessment of intrathoracic masses. This study was conducted to evaluate the diagnostic yield of the procedure as well as to demonstrate the spectrum of various disease in our population.Methods: Present study was conducted in a tertiary care hospital for a study period of two years. Patients with intrathoracic mass were included and CT guided biopsies were performed following a protocol. The CT guided biopsies received were examined for histological diagnosis. Immunohistochemistry was carried out where ever routine histopathology was not sufficient for diagnosis. Relevant immunohistochemical panels were applied for lung, mediastinal and pleural tumours according to the histological differential diagnosis. Detailed demographic and clinical profiles along with radiological findings were noted.Results: Total of 138 cases were taken for CT guided FNAC procedure and 123 (89.1%) cases yielded diagnostic biopsy. Lung was the most commonly involved organ followed by mediastinum. Bronchogenic carcinoma was the most common lesion reported in lung and Non-Hodgkin Lymphoma was the most common mediastinal lesion. Lung collapse was most common radiological feature.Conclusions: CT guided percutaneous biopsy is a valuable diagnostic technique providing for early accurate diagnosis and being minimally invasive procedure. Care should be taken while tissue processing and section cutting of intrathoracic biopsies as the biopsies are small and tissue loss should be prevented so that sufficient material is available for immunohistochemistry.

ABSTRACT Objective: To evaluate the diagnostic accuracy of CT-guided percutaneous core needle biopsy (CT-CNB) of pulmonary nodules ≤ 2 cm, as well as to identify factors influencing the accuracy of the procedure and its morbidity. Methods: This was a retrospective, single-center study of 170 consecutive patients undergoing CT-CNB of small pulmonary nodules (of ≤ 2 cm) between January of 2010 and August of 2015. Results: A total of 156 CT-CNBs yielded a definitive diagnosis, the overall diagnostic accuracy being 92.3%. Larger lesions were associated with a higher overall accuracy (OR = 1.30; p = 0.007). Parenchymal hemorrhage occurring during the procedure led to lower accuracy rates (OR = 0.13; p = 0.022). Pneumothorax was the most common complication. A pleura-to-lesion distance &gt; 3 cm was identified as a risk factor for pneumothorax (OR = 16.94), whereas performing a blood patch after biopsy was a protective factor for pneumothorax (OR = 0.18). Conclusions: Small nodules (of < 2 cm) represent a technical challenge for diagnosis. CT-CNB is an excellent diagnostic tool, its accuracy being high.
