“…Among the many options for the treatment of benign and malignant tumors affecting multiple organs, image-guided percutaneous ablation is become increasingly more widely accepted ( 4 ) , especially in patients who are at high surgical risk (Figure 8). There are currently a number of thermal and non-thermal ablation modalities available ( 9 ) , including radiofrequency ablation, microwave ablation, cryoablation, high-intensity focused ultrasound, laser ablation, irreversible electroporation, chemical ablation (with ethanol or acetic acid), and brachytherapy (Figure 9).…”

Interventional radiology has been constantly developing in terms of the techniques, materials, and methods of intervention. It interacts with all areas of medicine, always with the ultimate goal of ensuring the well-being of patients. Advances in imaging techniques, especially in the last two decades, have led to a paradigm shift in the field of urological imaging interventions. Many urologic diseases that were previously treated only surgically can now be effectively managed using minimally invasive image-guided techniques, often with shorter hospital stays and requiring only local anesthesia or conscious sedation.

“…Ultrasound-guided fine-needle aspiration biopsy (FNAB) is a widely available, safe, and accurate procedure, but the effectiveness of the procedure depends on the skill and experience of the professional and requires adequate training 1 – 3 . FNAB is a technically challenging procedure for inexperienced clinicians with sensitive nearby structures such as the jugular veins, carotid arteries, and trachea.…”

OBJECTIVE:To evaluate the efficacy of a training program in ultrasound-guided fine needle puncture using a cost-effective model. METHODS: We evaluated the training of 20 resident radiology physicians, based on a theoretical course and a practical simulation part with models that focused on the puncture technique of thyroid nodules. The total time to perform the procedure, the number of punctures on the model surface, and the application of a questionnaire were used to assess the performance and confidence of the resident physicians in performing the procedure. RESULTS:The training model used was easy to reproduce, inexpensive, versatile, and capable of simulating the echotexture of thyroid tissue. There was a significant reduction in the total time needed to perform the procedure with a mean of 173.7 s±91.28 s from R1 and 112.8 s±17.66 s from R2 before the course vs. 19.2 s±112.8 s and 14.3 s±9.36 s, respectively, after the course (p<0.0001); as well as the number of superficial punctures, with a mean of 2.2 punctures±0.92 from R1 and 1.5 punctures±0.32 from R2 before the course vs 1.1 punctures±0.71 and 1.0 puncture±0.0, respectively, after the course (p<0.0001). There was also a subjective improvement in the performance and confidence in performing this procedure. CONCLUSIONS: An inexpensive and easy-to-reproduce gelatin-based model enabled adequate training of resident physicians and proved capable of improving their skills and confidence in simulating the procedure, even with a short period of training.

Objective: To evaluate the accuracy of percutaneous transhepatic biliary biopsy (PTBB) in patients with suspected biliary obstruction. Materials and methods: This was a retrospective analysis of 18 patients with obstructive jaundice who underwent PTBB. In each patient, three to ten fragments were collected from the lesion. The final diagnosis was confirmed in the pathology report. We also reviewed analyses of the results of laboratory tests performed before the procedure, as well as the Bismuth classification, clinical outcome, complications occurring during the procedure, access route, and materials used. Results: Technical success was achieved in 100% of the PTBB procedures. Among the 18 patients clinically diagnosed with bile duct stenosis, the pathological analysis confirmed that diagnosis in 17. In one case, the pathological findings were considered false-negative. The predominant tumor was cholangiocarcinoma (seen in 50% of the cases). Sixteen of the procedures (88.9%) were performed without complications. Transient hemobilia occurred in one case, and cholangitis occurred in another. Conclusion: PTBB is a safe, viable, simple technique with a high rate of true-positive results for the definitive diagnosis of obstructive jaundice.
