Abdominal Wall Incisional Hernia Repair with the Anterior Component Separation Technique and Reinforcement with an Anterior Rectus Abdominis Sheath Flap

Abstract

Summary: Mesh repair is currently the mainstay of treatment for abdominal wall incisional hernias and is considered the standard of care. However, if radiotherapy is used, the possibility of complications such as exposure or infection of the prosthesis after the surgery as a complication of the radiotherapy is a concern. The patient was a 51-year-old woman who underwent laparotomy by a mid-abdominal incision for ovarian tumors. Approximately 2 years later, the patient presented with a hypertrophic scar of the wound and mild pain in the scar. The hypertrophic scar was improved gradually by corticosteroid injection. However, she had a bulge on the left side of the umbilicus just below the hypertrophic scar. Computed tomography showed a 65 × 69 mm2 hernial orifice on the left side of the umbilical abdominal wall, and an abdominal wall incisional hernia was diagnosed. The patient underwent closure by the ACS technique and reinforcement by unilateral inversion of the anterior rectus abdominis sheath for the abdominal wall incisional hernia. No recurrence of the hypertrophic scar or abdominal wall incisional hernia was observed during the follow-up period. In the present case, the hernial orifice was closed by a modified ACS technique that was combined with the anterior rectus abdominis sheath turnover flap. This technique is likely a less invasive and relatively simple method resulting in a tighter repair of the abdominal hernia than the ACS method alone, without prostheses.
