Autologous dermal grafts for rectus sheath reconstruction and application in closure of ventral myofascial defects

Abstract

Ventral abdominal hernias pose a reconstructive challenge, with recurrence rates after primary closure exceeding 50 % and synthetic options at high risk for infection. We describe our experience with using autologous dermis, sourced from the redundant overlying abdominal skin, for reconstruction of ventral abdominal wall defects. We describe the surgical technique, applied anatomy and an analysis of short- and long-term outcomes. Twelve consecutive patients undergoing repair of medium-large size, reducible abdominal wall defects were recruited. The dermal graft technique was used in each case, utilizing an autologous running strip of abdominal skin for reconstruction. Both short- and long-term outcomes were assessed prospectively. Scores were given on a scale of 1-10, with 1 = least/worst and 10 = most/best. The described technique was successfully undertaken in all patients. Long-term follow-up demonstrated a 100 % resumption of normal activities, with an improvement in quality of life and physical activity scores postoperatively, and no recurrences. Short-term complications were notable, with five patients requiring postoperative intensive care unit admission, and seven patients requiring respiratory support. In conclusion, the use of autologous rectus sheath reinforcement may achieve good surgical outcomes and high patient satisfaction. While early respiratory complications should be noted, the potential utility of this technique is worthy of future investigation.
