Summary
This study on vacuum-assisted breast biopsy (VAB) indicates a learning curve exists. Improved efficiency was observed after the 20th procedure, suggesting safe performance even early on.
Area of Science:
- Radiology
- Surgical Oncology
- Medical Devices
Background:
- Vacuum-assisted breast biopsy (VAB) offers an alternative to traditional core needle biopsy for diagnosing breast lesions.
- VAB systems are increasingly utilized for minimally invasive breast lesion evaluation.
Purpose of the Study:
- To investigate the learning curve associated with ultrasound-guided vacuum-assisted breast biopsy (VAB) procedures.
- To assess the impact of experience on the efficiency and safety of VAB.
Main Methods:
- Analysis of 54 patients undergoing ultrasound-guided VAB, divided into two groups (first 20 patients: Group A, next 34 patients: Group B).
- Comparison of operation times, complication rates, and probe positioning between Group A and Group B.
Main Results:
- A plateau in VAB procedure performance was observed after the 20th patient.
- Group B demonstrated significantly shorter total operation times compared to Group A (p < 0.001).
- While complication rates and probe positioning tended to be better in Group B, these differences were not statistically significant.
Conclusions:
- A learning curve exists for performing ultrasound-guided VAB procedures.
- VAB procedures can be conducted safely, even during the initial learning phase.
