Background: Previous studies have demonstrated that mastoscopic sentinel lymph node biopsy (MSLNB) has good identification rate (IR) and low false negative rate (FNR). However, few studies have directly compared the surgical performance and peri- and post-operative factors of MSLNB with conventional sentinel lymph node biopsy (SLNB). Methodology: Sixty patients diagnosed with breast cancer were recruited and randomly assigned to one of the three groups: MSLNB, SLNB and SLNB with lipolysis injection. Peri- and post-operative parameters were compared using general linear models. To examine the effect of age on these parameters, we performed separate analysis stratified by age (≤50 years old vs. >50 years old). Results: Patients in the MSLNB group experienced longer surgery and suffered higher surgical cost than patients who underwent conventional SLNB or SLNB with lipolysis injection (p<0.0001). Despite this, they had significantly less blood loss than those who underwent conventional SLNB (22.0±7.0 ml vs.73.5±39.6 ml; p<0.0001). Analysis by age group indicates a similar pattern of difference among the three groups. MSLNB and conventional SLNB have similar IR and FNR. Conclusion: As a minimally invasive technique, MSLNB can significantly reduce blood loss while providing similar IR and FNR, indicating that it can be a promising alternative to conventional SLNB. Conclusion: Variations in popliteal artery terminal branching pattern occurred in 7.4% to 17.6% of patients. Pre-surgical detection of these variations with MD CTA may help to reduce the risk of iatrogenic arterial injury by enabling a better surgical treatment plan.
