Comparing Outcomes of Robotically Assisted Latissimus Dorsi Harvest to the Traditional Open Approach in Breast Reconstruction.

Background: Robotically assisted latissimus dorsi harvest permits harvest of the latissimus dorsi muscle without a back incision, as compared to the traditional open technique. The authors hypothesized that robotic harvest has lower donor-site complication rates, decreased opioid requirements, and a shorter length of stay than the traditional open technique.

Methods: A retrospective review was performed of all consecutive pedicled latissimus dorsi flaps for breast reconstruction between 2011 and 2015. All procedures were conducted by two surgeons who performed both robotic and open cases.

Results: Fifty-two patients were identified; 25 underwent robotically assisted latissimus dorsi harvest and 27 underwent the open technique. Demographic data between the two groups were similar. Median length of stay for robotic harvest was shorter than that for the traditional technique (2 days versus 3 days; p = 0.031). Postoperative morphine requirement was less in the robotic compared to the traditional technique, but the difference was not significant (158 mg versus 184 mg; p = 0.826). Seroma rate was higher in the robotic group (16 percent versus 0 percent; p = 0.034). The mean duration of surgery was longer in the robotic cohort (388 minutes versus 311 minutes; p = 0.002).

Conclusions: This study demonstrates robotically assisted latissimus dorsi harvest as an effective alternative to the traditional open technique in select patients. Advantages of robotic harvest include no back scar, a shorter length of stay, and lower opioid requirements, although the difference was not significant; disadvantages include longer operative time and a higher seroma rate.
