The Usefulness of Endoscopic Harvesting of the Latissimus Dorsi Flap for Breast Reconstruction Using a Single-Port and CO Gas Insufflation Technique.

Background: In the recent trend toward less aggressive approaches to breast reconstruction, minimally invasive harvesting of the latissimus dorsi (LD) flaps has long been a desirable goal. Endoscopically-assisted LD flap harvesting was reported as a method for minimizing scar formation and reducing donor-site morbidity. This study investigates the surgical outcomes of endoscopically-assisted immediate breast reconstruction with LD muscle flaps.

Materials And Methods: This prospective study included 21 patients who underwent endoscopically-assisted breast reconstruction with LD muscle flap and 20 patients who underwent breast reconstruction with conventional harvesting LD musculocutaneous flap. In patients with nonexcised skin or possible primary closure, the reconstruction was performed with endoscopically-assisted LD muscle flaps using the single-port and CO gas insufflation technique. The patients were classified into groups according to the location of the defect and mastectomy type. Moreover, patient satisfaction was investigated 6 months after surgery.

Results: In patients who underwent endoscopically-assisted breast reconstruction with LD muscle flaps, the scar of the donor-site was vertical, and the size was 4 cm to be obscured when lowering the arms. In comparison with patients who underwent breast reconstruction with conventional LD flaps, those who underwent endoscopically-assisted breast reconstruction with LD muscle flaps showed shorter hospital stay and no difference in patient satisfaction.

Conclusion: Endoscopically-assisted breast reconstruction with LD flaps showed no difference in patient satisfaction with good esthetic results compared with conventional LD flaps. The endoscopic LD muscle flap harvest technique using a single-port and CO2 insufflation technique can be very useful in breast reconstruction that does not require a skin paddle.
