Salvaging Complex Lower Extremity Injury with Laparoscopically Harvested Omental Flaps.

BACKGROUND

Traumatic injuries to the lower extremities are frequently accompanied by extensive soft tissue loss, combined with vascular damage or exposure of bony tissues, making it difficult to reconstruct; consequently, patients are commonly at risk of amputation. Due to its superior anatomical and biochemical properties, the omental flap has been used to reconstruct soft tissue defects for decades. However, few studies have reported the omental flap's effectiveness in treating severe and complex lower extremity deformities. We attempted to use a laparoscopically harvested omental flap in conjunction with a second-stage skin graft to reduce infections during limb preservation, increase flap survival probability, and restore the aesthetic and functional integrity of the affected extremity.

METHODS

Seventeen patients with severe lower extremity wounds underwent omental flap transplantation and were followed up for 6 to 12 months to check for surgical complications, evaluate cosmetic results, and ensure proper limb function.

RESULTS

There were no complications, such as intestinal adhesion, intestinal volvulus, and peritonitis, with any of the omental grafts. The affected extremities were well-functioning and aesthetically pleasing.

CONCLUSION

Laparoscopically harvested omental flap transplantation with skin grafting is an alternative reconstruction technique for severe lower extremity injuries with massive soft tissue loss and exposed bones and tendons.
