Surgical technique for epigastric incisional hernia after omphalocele repair: bilateral modified composite flaps using the upper rectus abdominis muscle and the vertically inverted flap of the lower rectus abdominis fascia.

We present a patient who developed an incisional hernia, from epigastrium to umbilicus, after omphalocele repair. The hernia gradually enlarged to a 10 cm × 10 cm defect with significant rectus abdominis muscle diastasis at the costal arch attachment point. At 6 years of age, the abdominal wall defect in the umbilical region was closed using the components separation technique. For the muscle defect of the epigastric region, composite flaps were made by suturing together the flap of the upper rectus abdominis muscle, after peeling it away from the costal arch attachment point, and the vertically inverted flap of the lower rectus abdominis fascia, created with a U-shaped incision. The composite flaps from each side were reversed in the midline to bring them closer and then sutured; the abdominal wall and skin were then closed. Five months after surgery, the patient had no recurrent incisional hernia and no wound complications.
