Ventral abdominal hernias are a common abdominal wall defect in the United States. We present a 50-year-old Caucasian male with a large (>18 cm) abdominal wall defect. An extensive complex abdominal wall reconstruction with advanced bilateral fascial flaps/component separation and repair of the abdominal wall defect was planned to restore the appropriate abdominal wall anatomic contour. The use of double mesh in large abdominal wall defects is still a relatively new documented technique. Only two case series detail the same technique used on this patient, with no articles on using a hybrid mesh with a synthetic absorbable mesh. This case uses an underlay and onlay mesh technique, with a hybrid mesh, Tela Biologics (Malvern, PA, USA), under the muscle, in this case, intraperitoneal bridging the gap. The anterior rectus sheath was reinforced with intercepted 0-Ethibond sutures (Ethicon/J&J, Bridgewater, NJ, USA) and then reinforced with a synthetic absorbable mesh (PhasixTM, Becton Dickinson, Franklin Lakes, NJ). The outcome with this patient shows more research should be conducted on considering long-term results with the types of mesh and the question of whether there are additional benefits when using two different types of mesh and their placement in the sandwich technique.

Seat belt syndrome (SBS) represents all injury profiles associated with seat belt injuries and motor vehicle crashes (MVCs). Seat belt syndrome classically presents with a superficial seat belt sign that may signify deeper intra-abdominal and/or spinal involvement. The amount of force transmitted from the restraint to the passenger ultimately dictates the amount and severity of the injury. We present a unique case of a 59-year-old female involved in a motor vehicle crash with multiple traumatic injuries, including seat belt syndrome, abdominal wall transection, and bowel injuries. She later had reconstruction of her traumatic abdominal wall hernias (TAWHs). Three unique approaches were used in the management of her traumatic abdominal wall hernias: (1) preoperative Botulinum toxin (Botox) injections, (2) operative use of biologic and bioabsorbable meshes in contaminated fields, and (3) postoperative physical therapy and body positioning. The patient did not experience any recurrence of these hernias after her abdominal wall reconstruction and remains alive at the time this case was written. The diagnostic criteria and surgical management of traumatic abdominal wall hernias have yet to be established, and the case presented here provides approaches that should serve as future areas for study.
