“…Typically, indeterminate pulmonary nodules have low‐to‐intermediate probability of malignancy. 6 , 7 , 8 In particular, surgical diagnosis and treatment have disadvantages in common pulmonary nodules whose nature is difficult to determine clinically, as well as in pulmonary nodules in which pathological results are necessary to determine the treatment method. 9 , 10 , 11 In contrast, CT‐guided percutaneous transthoracic needle biopsy (PTNB) has the advantages of safety, effectiveness, accuracy, and convenience and is widely used in clinical practice.…”

Background Few studies have investigated the learning process of percutaneous transthoracic needle biopsy (PTNB). Here, we aimed to evaluate the number of cases required to achieve proficiency by plotting the learning curve of PTNB. Methods Data were collected from 94 consecutive patients who underwent computed tomography–guided PTNB by a thoracic surgeon at the Affiliated Hospital of Xuzhou Medical University between May 2021 and February 2022. The data collected included patient information, relevant examination results, intraoperative parameters, postoperative complications, and diagnostic results. Results The inflection points of the cumulative sum curve were around cases 13 and 24, according to which three phases were identified, including phase I, phase II, and phase III. A significant downtrend was observed regarding operative time (phase I, 26.53 ± 9.13 min vs. phase III, 18.42 ± 4.29 min, p < 0.05), rate of false‐negative (phase I, 15.4% vs. phase III, 5.7%; p < 0.05), rate of pneumothorax (phase I, 30.8% vs. phase III, 12.9%; p < 0.05), and rate of hemoptysis (phase I, 15.4% vs. phase III, 2.9%; p < 0.05). Conclusions Thirteen cases were accumulated to lay the technical foundation, and 24 cases were required to achieve proficiency. In this study we summarize our own experience and provide specific guidance for young doctors with no experience in biopsy.

Objective — determination of the size and localization of solitary pulmonary nodules (SPN) of various etiology and their qualitative-quantitative characteristics when separated into malignant and benign formations. Materials and methods. The randomized retrospective study involved 422 patients who were hospitalized in the National Institute of phthisiology and pulmonology named after F.G. Yanovsky from 2017 to 2021. Criteria for inclusion in the study group are focal lesions of the lungs of unclear etiology, the size of which did not exceed 3,0 cm, and the presence of no more than 3 foci in both lungs of one patient according to X-ray examination. The number, size and location of the SPN were determined according to X-ray examination or computed tomography of the chest organs.. A total of 473 nodules were found. The etiology of SPN was determined according to the results of histological and cytological examination of biopsy or operative material and/or microbiological data. All nodules were divided into three groups, depending on their size. Results and discussion. The etiological spectrum of all revealed SPN in the five-year period is determined. It was established that among all SPN malignant tumors (39.1 %) are dominated the average size of which was (2.14 ± 0.1) cm, on the second place in the number of observations were nodules of infectious origin (31.0 %), the average size — (1.97 ± 0.1) cm, and on the third — benign tumors (18.7 %). the average size — (1.57 ± 0.1) cm. The average size of malignant tumors and SPN of infectious origin was significantly larger than the size of benign tumors and vascular formations. It was shown that in a group with SPN sizes 0.3—1.0 cm malignant tumors amounted to 22.9 %. and in a group with a size from 2.1 to 3.0 cm — 51.5 %, respectively 55.3 % of all SPNs were found in the right lung, 44.7 % in the left. In the upper lobe of the right lung. 52.3 % of nodules were found. which is significantly more than in middle. 16.0 % of SPN (p < 0.001), and the lower lobe — 31.7 % (p < 0.001). In the upper lobe of the left lung. 59.4 % of SPN were diagnosed, and in its lower lobe — 40.6 % (p < 0.001). Conclusions. Among all solitary pulmonary nodules of various etiology. the largest specific gravity have malignant nodes — 39.1 % and nodules of infectious genesis — 31.0 %. and the average size of these SPN is essentially larger than the size of benign tumors and vascular formations. The percentage of malignancies increases from 22.9 to 51.4 % with an increase sizes of SPN from 1.0 to 3.0 cm. Significant predominance by the number of nodules in size from 1.1 cm to 3 cm is evidence of improper level of detection SPN in Ukraine. Solitary pulmonary nodes are significantly more often found in the right lung. Moreover, lesions of the upper lobes of the right and left lungs are observed more often than the lower lobes of the lungs.
