Abstract
OBJECTIVE: To investigate the reconstructive methods and effectiveness of modified pedicled anterolateral thigh (ALT) myocutaneous flap for large full-thickness abdominal defect reconstruction. METHODS: Between January 2016 and June 2018, 5 patients of large full-thickness abdominal defects were reconstructed with modified pedicled ALT myocutaneous flaps. There were 3 males and 2 females with an average age of 43.7 years (range, 32-65 years). Histologic diagnosis included desmoid tumor in 3 cases and sarcoma in 2 cases. The size of abdominal wall defect ranged from 20 cm×12 cm to 23 cm×16 cm. Peritoneum continuity was reconstructed with mesh; lateral vastus muscular flap was used to fill the dead space and rebuild the abdominal wall strength; skin grafting was applied on the muscular flap, the rest abdominal wall soft tissue defects were repaired with pedicled ALT flap. The size of lateral vastus muscular flap ranged from 20 cm×12 cm to 23 cm×16 cm, the size of ALT flap ranged from 20 cm×8 cm to 23 cm×10 cm. The donor site was closed directly. RESULTS: All flaps and skin grafts survived totally, and incisions healed by first intention. All patients were followed up 6-36 months (mean, 14.7 months). No tumor recurrence occurred, and abdominal function and appearance were satisfying. No abdominal hernia was noted. Only linear scar left in the donor sites, and the function and appearance were satisfying. CONCLUSION: Modified pedicled ALT myocutaneous flap is efficient for large full-thickness abdominal defect reconstruction, decrease the donor site morbidity, and improve the donor site and recipient site appearance.
