Abstract

IntroductionMore than half of the patients with an impalpable malignant breast lesion have a mammographically detected and imaged-guided localisation, which can be technically challenging for the breast surgeon. Specimen imaging is used to confirm successful excision of the localised index lesion and has improved the operating list efficiency resulting in a higher number of excisions per surgical list. The aim of this study was to evaluate whether introducing IDSM (intra-operative digital specimen mammography) saved operation time for localised breast surgery.

MethodsA single-centre retrospective review was undertaken to compare the operation time (from incision to wound closure) taken for excision of 114 consecutive image-guided localised impalpable breast lesions, performed using departmental specimen radiography (DSR), 6months prior to the introduction of IDSM (Hologic, Trident((R))) in March 2013, with the theatre time taken for excision of 121 consecutive image-guided localised impalpable breast lesions in the 6months following introduction of IDSM.

ResultsThere was no significant difference in mean surgical time, which were 47.8 (27.3) minutes in the CSR group and 48.8 (+/- 25.7) minutes in the IDSM group.

ConclusionWe were expecting to confirm a reduction in theatre time with the introduction of IDSM. Surprisingly, no difference in operating times was demonstrated. Factors that influenced the impact of IDSM included the proximity of the imaging department to the operating theatre.
