Background

Compared with conventional open breast-conserving surgery (breast-conserving surgery), conventional endoscopic (E-breast-conserving surgery) mostly involves dual incisions, which provide an insignificant scarring benefit but increase the surgical difficulty and prolong the surgical time.

Methods

Were assigned to M-E-breast-conserving surgery or conventional open breast-conserving surgery (C-O-breast-conserving surgery).

n = 163 patients

Results

scar satisfaction was much higher after minimal-incision surgery than open surgery

M-E-BCS

79.9SCAR-Q

C-O-BCS

61.4SCAR-Q

More results

The 18-month SCAR-Q score was available for 155 patients (8 missing, 4 per group).

One patient in the conventional open BCS group developed bone metastasis at 5 months, and another developed axillary lymph node recurrence at 17 months.

No local recurrence or death occurred in either group.

Conclusion

M-E-BCS significantly improves aesthetic outcomes and quality of life compared to conventional open BCS, without compromising surgical efficiency or safety for early-stage breast cancer patients, supporting its clinical adoption.
