Abstract:
Introduction: Traditionally, wire-guided localisation has been the gold-standard for localising non-palpable breast lesions. However, this method has some limitations, including patient discomfort, wire migration and scheduling radiology appointments on the day of surgery, causing delay in start of theatre list. Various wire-less alternatives have been developed. Therefore, the aim of this study was to evaluate the safety and effectiveness of the SAVI SCOUT localisation technique. Method(s): This was a prospective study of 137 consecutive patients with SAVI SCOUT reflector, deployed between December 2020 and November 2023. We studied the rate of successful localisation and retrieval of SCOUT, imaging modality used for localisation, re-excision rate, pathology, median weight of specimen and SCOUT-related complications. Result(s): A total of 137 SAVI SCOUT reflectors were deployed in 137 consecutive patients undergoing breast conserving surgery for non-palpable lesions which included malignancy 97% (n=133), high risk lesions 2.18% (n=3) and benign lesion in 0.72% (n=1). The rate of radiological localisation and retrieval of the reflector at surgery was 97.8% (n=134) and 100% (n=137) respectively. The most common modality for localisation was ultrasound 97% (n=133). The median specimen weight was 21.5gm. The mean duration between deployment day and surgery was 2 days (range 0-30). The re-excision rate was 8% (n=11). There was no specific technique-related surgical complication. Conclusion(s): Our study demonstrates that the SAVI SCOUT localisation system is a safe, effective, and reliable localization modality for non-palpable breast lesions with low re-excision rate.
