From Open to Robotic-assisted Latissimus Dorsi Muscle Flap Harvest.

The latissimus dorsi muscle is the largest muscle in the body. The classic open flap harvest technique of this muscle results in a long posterolateral thoracic vertical oblique incision that can leave an unappealing scar. The minimally invasive robotic approach has the potential to reduce scar length and to overcome technical limitations of endoscopic techniques. Six robotically assisted latissimus dorsi muscle flaps were harvested by a single surgeon. One was used as reversed turnover pedicled flap based on lumbar perforators for lumbosacral bone coverage, another flap was transposed for a Poland syndrome anterior axillary line reconstruction, and the remaining 4 were dissected as free flaps for upper and lower limb reconstruction. All 6 procedures used a short 5-cm axillary crease incision along the posterior axillary fold and two 8-mm port incisions for robotic access. The first robotic flap harvest was converted to the classic open technique due to malposition of the 2 lower port incisions too close to the latissimus dorsi anterior border. The 5 other flaps were successfully transferred without flap or donor site complications. The average flap dissection time was 110 minutes; latter surgeries took less time than the early surgeries as the surgeon became more familiar with the robotic system and due to the use of a newer system. Robotic-assisted latissimus dorsi muscle flap harvest is a safe, reproducible, and effective tool that offers precise dissection control and that leaves a minimal thoracic scar.
