Abstract
AIM
The study investigated the effect of collagen mesh-assisted closure at the donor site in preventing the formation of incisional hernia following construction of a vertical rectus abdominis myocutaneus (VRAM) flap as part of pelvic surgery for recurrent colorectal cancer.
METHOD
The study was a double-blinded randomized controlled superiority trial that was designed and performed according to the Consolidated Standards of Reporting Trials (CONSORT) Statement. Eligible patients undergoing surgery that included a VRAM flap for advanced colorectal pelvic malignancy were prospectively randomized to conventional abdominal wound closure or collagen mesh-assisted closure. The primary end-point was incisional herniation at 1 year confirmed by CT. Secondary end-points were CT-verified incisional herniation at 3 and 36 months, clinically recognizable incisional herniation, donor-site and reconstructive-site complications, surgical mortality, postoperative morbidity, postoperative recovery and survival.
RESULTS
In total, 58 (29 conventional closure; 29 mesh-assisted closure) patients were included. At 1 year, incisional herniation on the CT scan was found in 12 (50%) of 24 patients in the conventional closure group, and in 8 (33%) of 24 in the mesh-assisted closure group (P = 0.38). No significant difference between the groups was found in surgical mortality, early or late complications or survival. Donor-site morbidity was comparable between the two groups.
CONCLUSION
No preventative effect of collagen mesh-assisted closure was observed following VRAM flap reconstruction.
