The rectus abdominis muscle is a workhorse flap for reconstructing challenging defects. Owing to its strategic location in the abdomen with a dual blood supply and wide arc of transposition, it can provide substantial coverage and a large volume for obliterating dead spaces while maintaining a reliable vascular supply. Using traditional approaches, however, its harvest has the potential for donor-site morbidity. We have previously highlighted the advantages of using the robot for harvesting the latissimus dorsi muscle flap.1-3 In this review, we discuss the applicability of this novel approach to muscle harvest for a minimally invasive harvest of the rectus abdominis muscle flap.
Main SectionVersatile Flap: Dual Blood SupplyThe rectus abdominis muscle flap has two major blood supplies: the superior epigastric artery and its associated venous drainage system, which provides a cephalic arc of rotation, and the inferior epigastric artery and veins, which provide a caudal arc of rotation. It has thus found applications in perineal, 4 extremity, 5 chest wall, 6 and even head and neck reconstruction.

Complications of the Traditional Harvest TechniqueHarvest of the rectus muscle is typically performed through a vertical, paramedian skin incision, followed by vertical division of the anterior rectus sheath along the length of the muscle (►Fig. 1). This technique is both aesthetically undesirable and is associated with donor-site morbidity, including wound infection, seroma, abdominal bulge, and hernia. Reported bulge rates are between 1.7 and 4% with hernia rates between 0.85 and 2.9%. 9-12 Overall surgical-site morbidity may be as high as 8.5 to 14.3%. 9,12 Minimally invasive harvest of the rectus abdominis muscle without violation of the anterior rectus sheath is a desirable goal. This approach might not only circumvent the surgical complications associated with the traditional approach, but could also allow for

AbstractHarvest of the rectus abdominis muscle requires an abdominal incision as well as violation of the anterior rectus sheath, creating the potential for significant surgicalsite morbidity (bulges, hernias, infections, seromas). Laparoscopic or endoscopic techniques, although feasible, have not become popular among plastic surgeons due to multiple technical shortcomings. Robotic surgery on the other hand has an easier learning curve, enhanced precision, tremor elimination, motion scaling, high resolution, three-dimensional optics and an intuitive interface. As a result of these advantages, robotic surgery has permeated into the plastic surgery specialty, assuming a role in the harvest of the latissimus dorsi muscle flap and other reconstructive procedures. In this review, the authors discuss its applicability in the harvest of the rectus abdominis muscle.
