A Variation of the Components’ Separation Technique that Preserves the Semilunaris for Treatment of Abdominal Wall Deformities

Abstract

AbstractThe variation of the components’ separation technique, which uses the anterior rectus sheath and the release of the oblique muscles, proved to be effective in tension reduction. This paper aimed to present the initial experience using a variation that preserves semilunaris through the incision of the lateral aspect of the rectus sheath. All of the 12 patients presented an abdominal wall defect that included incisional hernia, peritoneostomy, lateral implantation of the rectus muscle, and defect secondary to TRAM flap. The separation was done in the following stages: stage 1—anterior rectus sheath and stage 2—external oblique muscles. From the 12 patients, three presented early complications: seroma (n = 2) and epitheliolysis (n = 1). There were no recurrences or other late complications (48 months follow-up period). The separation of the anterior rectus sheath, and incision in the lateral recess to undermine the oblique muscles, allowed the treatment of abdominal wall defects, without late complications.
