The present study aimed to evaluate the applicability of artisanal simulators to teach veterinary and medical students the ultrasound-guided percutaneous biopsy using a tru-cut needle. The artisanal simulators consisted of bovine liver between two layers of commercially available grape gelatin. Students were paired, with one doing the biopsy and the other the ultrasound guidance. After performing the biopsies, each student answered a questionnaire with close-ended questions using a visual analog scale. The evaluated items were realism of the model, liver scanning, procedure instructions, biopsy feasibility, tru-cut needle handling, technique learning, and confidence to perform in vivo procedures. Items that received a score of 7 or higher were considered strong items; items with a score between 5 and 6.9 were classified as average items; and items with a score of 5 or lower were considered weak items. The answers to all questions had an average score of 7 or higher, suggesting that the simulator was classified as strong for all of the evaluated items. Answers to question 7 suggested that some of the students did not develop confidence to perform a tru-cut biopsy on a patient. Students evaluated the artisanal simulator as a strong method to be used in ultrasound-guided percutaneous biopsy with a tru-cut needle. Additionally, the model presented a low cost of production and was proven accurate to teach biopsy skills in health professional schools dealing with veterinary or human medicine. |
