Robotic-assisted skin sparing mastectomy and immediate reconstruction using latissimus dorsi flap a new effective and safe technique: A comparative study.

Breast reconstruction is an essential part of breast cancer treatment. After skin sparing mastectomy, Immediate Breast Reconstruction (IBR) can be achieved using breast implants, autologous flaps (i.e. latissimus dorsi-myo-cutaneous flap (LDF)) or an association of both. Robotic assistance has gained popularity in many surgical fields including breast surgery. This study aims to compare the post-operative results of Robotic Assisted Latissimus Dorsi Flap (RALDF) to Traditional Latissimus Dorsi Flap (TLDF) for IBR after Skin Sparing Mastectomy (SSM) without nipple conservation. Between March 2016 and June 2019, all patients who underwent a SSM and a concurrent IBR with a TLDF were retrospectively compared to patients who underwent SSM and a concurrent IBR with a RALDF. Outcomes compared included operative time, length of hospital stay and complications rate. 105 cases of SSM with a LDF based IBR were included in the study. 46 patients underwent RALDF and 59 patients underwent TLDF. Mean operative time was longer in the RALDF group (290.5min versus 259.7min). In binary regression, the concomitant placement of breast implant was the only factor associated with an operative time exceeding 290 min (p = 0.032). Univariate analysis showed no significant difference concerning the rate of complications (p = 0.061). After logistic regression, RALDF was associated with a decreased rate of complications (p = 0.042; OR 0.37; IC 95% (0.142-0.966)). SSM with IBR using RALDF is an effective and safe technique. This technique is actually associated with a lower complication rate at the expense of a longer operative time.
