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.
