NCBI ROFL: How is a woman’s breast like a pork roast? (hint: it involves pimento olives).

Ultrasound-guided breast biopsy for surgical residents: evaluation of a phantom model.

“BACKGROUND:
Ultrasound is increasingly used by surgeons for evaluation of breast lesions. While surgical residents have sufficient exposure to breast surgery, many lack exposure to office-based procedures, such as ultrasound-guided breast biopsy. A phantom model was created to teach surgical residents basic breast ultrasound and biopsy skills and to evaluate the resident’s response when incorporated into the curriculum.
METHODS:
The model was created using a pork roast and 10 variably-sized pimento olives. Twenty-four surgical residents were given a brief introduction to breast ultrasound followed by up to 5 minutes to ultrasound the model and note the embedded lesions. The number and location of lesions found and the time spent per resident were recorded. Residents were then introduced to the vacuum-assisted core biopsy system and observed performing ultrasound-guided biopsies. Pre- and postsession evaluations were completed by all residents. Scatterplot regression models were used for data analysis.
RESULTS:
Most residents had previous ultrasound instruction. The intermediate level residents (postgraduate year [PGY]2 and 3) found the most lesions in the shortest time, missing on average 1.125 lesions in 3:09 minutes. Time spent did not correlate with number missed or previous ultrasound experience. Over 50% of residents sampled the center of the lesion on their first biopsy attempt, with no correlation to PGY or ultrasound experience. All residents rated this experience good to excellent, and 67% believed their ultrasound skills were improved. Ninety-five percent of residents felt the model was fairly realistic and 95% would like to have more experiences like this in the curriculum. The residents surveyed thought the curriculum would be best suited to a PGY2 experience.
CONCLUSIONS:
The phantom breast is a realistic and valuable teaching model for breast ultrasound. Further evaluation regarding skill retention is needed.”
