简要总结
Objective: to evaluate the perforator based interposition plasty in comparison to the standard technique (full thickness graft) for scar contracture releases.
Study design: A randomised controlled multicentre intervention study.
Study population: Patients, aged 18 years and older, who require surgery for release of a scar contracture, are eligible for this study. In total 50 patients will be recruited with a follow-up of 3 months post-operatively.
Intervention: A release of the contracture will be performed in combination with òr the standard technique (full thickness graft) òr the perforator based interposition plasty.
Main study parameters/endpoints: the main study parameter is the amount of contraction of the flap/graft after three months.
详细描述
Rationale:
Scar contracture remains a considerable problem for the burned patient. The standard method of treatment is contracture release in combination with the application of a full or split thickness graft to close the defect. Unfortunately, the effectiveness of skin grafts is limited by scar contraction, which often necessitates additional reconstructions. Moreover, parts of the skin graft may be lost due to poor revascularisation or infection.
Since the discovery of perforator vessels, many types of new flaps can be harvested as long as it incorporates a perforator bundle (artery and vein). This flap design based on perforator vessels and local available skin, should lead to an increased flap survival and superior functional outcome. Based on this concept we developed and explored the possibility of an algorithm for treatment by means of a pilot study performed on 22 patients with a scar contracture. Results show a survival of all flaps of 100% and an expansion of the surface area by 16% after a follow up of at least 3 months. However the implications of the use of perforator based flaps for burn surgery by means of a RCT has yet to be determined.
Primary objective:
Is interpositioned skin of superior quality, as represented by less contraction with the use of the perforator based interposition flaps, compared to the gold standard (full thickness grafts), after 3 months, as measured by transparent sheet planimetry?
