Single-stage Abdominoplasty Using Groin Flaps Without Osteotomies: Management of Exstrophy-epispadias Complex.

Background and Objective: The optimal treatment for children born with exstrophy-epispadia complex is still a matter of debate. ^{1,2 , 3} We demonstrate the Single-Stage Abdominoplasty using Groin Flap technique to close the abdominal wall of children with classic bladder exstrophy (CBE) without osteotomy neither radical soft tissue mobilization. Advantages over current techniques are less risk of penile tissue loss and avoidance of osteotomies.
Material and Methods: Abdominal wall repair consists in using the hypogastric skin, rectus, and obliquus externus abdominalis muscle fascial flaps. These groin flaps are rotated medially resulting in a very strong abdominal wall support. Groin flaps are made of rectus anterior fascia rotated medially, flipped over, and sutured with Prolene sutures to close the defect. By rotating the fascial flaps medially, complete reinforcement of the abdominal wall to the level of the pubic bone is achieved. This permits abdominal closure maintenance without tension.
Results: Groin flap was applied to 128 patients with CBE referenced from all over the country. Most of these patients returned to their home areas making difficult their follow up. However, we have 44 cases that have regular clinical visits. Mean follow-up was 10.3 ± 4.5 years (2 years 8 months-16 years). Successful closure was achieved in 43 patients (97.7%) as a single procedure; one patient had a complete wound dehiscence and needed another reconstruction (2.2%). Four patients (9.1%) presented abdominal hernias that needed surgical management. When continence is evaluated, we present similar literature rates (60%). ⁴ CONCLUSION: Abdominal reconstruction using Groin flaps has advantages over the traditional approaches to CBE. It reduces the surgical steps and facilitates the closure of the abdominal wall without the need of osteotomies and consequent immobilization during the postoperative period. It is feasible at any age and can be also very useful as a salvage technique even after previous failed procedures. Finally, it minimizes the number of surgeries.
