Reconstruction of Complex Groin Defects After Sarcoma Resection.

Abstract

Complex groin defects after sarcoma resection require reconstruction of multiple vital structures that can include the major vessels, the overlying skin, the abdominal wall, and the hip joint. We investigated the feasibility of limb preservation after complex groin reconstruction. The subjects were 12 consecutive patients who underwent complex groin reconstruction after sarcoma resection. In all patients, the defect included a major artery (external iliac or femoral) and overlying skin. The defect included the abdominal wall in 5 patients and the hip joint in 2. Arterial reconstruction was performed with an autologous vein graft in 9 patients and with an expanded polytetrafluoroethylene graft in 3. Soft-tissue coverage was performed with a pedicled rectus abdominis musculocutaneous flap in 7 patients, a free latissimus dorsi musculocutaneous flap in three, and a free anterolateral thigh flap in 2. Postoperative complications occurred in 7 patients (58.3%). Limb salvage was possible in 8 patients (66.7%) with 39 months' median follow-up. Two patients required amputation because of wound problems, and 2 required amputation because of local recurrence of the tumor. Limb salvage is possible even after extensive resection of groin sarcoma, although the rate of postoperative wound complications is substantial. Proper selection of the arterial conduit and the soft-tissue flap, depending on the components of the defect, are mandatory for successful reconstruction.
