Effects of flap or myocutaneous flap combined with fascia lata or composite mesh on repairing severe high-voltage electrical burn wounds in abdomen of patients

Objective: To investigate the effects of flap or myocutaneous flap combined with fascia lata or composite mesh on repairing wounds in abdomen of patients with severe high-voltage electrical burn.

Methods: From January 2010 to May 2017, 11 patients with severe high-voltage electrical burn in abdomen were hospitalized in our burn wards. In 3 hours to 7 days after burn, operation was performed when patients were in stable condition. After debridement, intestines with necrosis or perforation in 4 patients with peritoneal defects were resected and intestinal anastomosis was performed. The size of abdominal wounds after debridement ranged from 13 cm×9 cm to 41 cm×32 cm. Five patients were treated with rectus abdominis myocutaneous flap and size of which ranged from 14 cm×10 cm to 30 cm×17 cm. Among the above 5 patients, 4 patients with peritoneal defects used composite mesh of 25 cm×20 cm to enhance abdominal wall. Three patients were treated with tensor fascia lata myocutaneous flap, and size of the flap ranged from 24 cm×10 cm to 27 cm×13 cm. Three patients were treated with anterolateral thigh flap with fascia lata, and one of them was treated with the lobulated flap; size of the flap ranged from 18 cm×13 cm to 25 cm×15 cm. The later 6 patients used fascia lata of flap to enhance abdominal wall. The donor sites were sutured directly or repaired with intermediate split-thickness skin graft of thigh.

Results: After operation, flaps or myocutaneous flaps of patients were survived, and strength of abdominal wall recovered. During follow-up of 6 month to 1 year, flaps or myocutaneous flaps were in good appearance, with no ankylenteron or abdominal wall hernia.

Conclusions: Flap or myocutaneous flap combined with fascia lata or composite mesh can achieve good effects on repairing severe high-voltage electrical burn wounds in abdomen.
