Application of pedicled anterolateral thigh myocutaneous flap for full-thickness abdominal wall reconstruction after tumor resection / 中国修复重建外科杂志

ABSTRACT

Objective: To explore the effectiveness of pedicled anterolateral thigh myocutaneous flap for full-thickness abdominal wall reconstruction after tumor resection. Methods: Between September 2010 and December 2017, 18 patients with abdominal wall tumors were collected. There were 11 males and 7 females, with an average age of 45.2 years (range, 29-68 years). Histologic diagnosis included desmoid tumor in 8 cases, sarcomas in 6 cases, malignant teratoma in 2 cases, and colon adenocarcinoma in 2 cases. All abdominal wall defects were full-thickness defects. Peritoneum continuity was reconstructed with mesh; the lateral vastus muscular flaps were used to fill the dead space and rebuild the abdominal wall strength; the abdominal wall soft tissue defects were repaired with pedicled anterolateral thigh flaps. The size of abdominal wall defects ranged from 15 cm×6 cm to 25 cm×22 cm; the size of lateral vastus muscular flap ranged from 10 cm×8 cm to 22 cm×10 cm; the size of anterolateral thigh flap ranged from 14.0 cm×8.0 cm to 21.0 cm×8.5 cm. The bilateral pedicled anterolateral thigh myocutaneous flaps were harvested to repair the extensive abdominal wall defects in 2 cases. All donor sites were sutured directly. Results: All wounds healed smoothly and all flaps survived totally. All donor sites healed smoothly. The mean follow-up time was 22.5 months (range, 11-56 months). No tumor recurrence occurred, the abdominal function and appearance were satisfactory, no abdominal hernia was noted. Only linear scar left at the donor sites. Conclusion: Pedicled anterolateral thigh myocutaneous flap combined with mesh is fit for large full-thickness abdominal defect reconstruction.
