Brief Summary

Autologous glue therapy with platelet-rich plasma (PRP) was reported to improve outcomes in plastic surgery. However, only pilot studies and retrospective uncontrolled trials have reported the potential benefits of autologous glue treatment up to now. Therefore, a larger, blinded, randomized and placebo-controlled clinical trial would be useful to determine whether platelet-rich plasma is safe and effective in abdominoplasty procedures. Currently, there are pharmacological options such as artificial fibrin glues composed of homologous fibrinogen and animal-derived thrombin. However, these therapeutics present a risk of transmissible diseases and may induce allergic reactions. Therefore, autologous glues, which are fully made of blood components from the patient itself (autologous fibrinogen contained in PRP and autologous thrombin) represents a safe alternative to artificial biological glues. Regen Lab SA developed RegenKit®-Surgery to prepare autologous PRP, on one hand, and an autologous activated thrombin serum, on the other hand, in a safe and rapid manner. RegenKit®-Surgery is a CE-marked class IIb medical device. This study, conducted on 56 patients, will evaluate the effects of autologous glue prepared with RegenKit®-Surgery when used in reconstructive abdominoplasty.

    Maximum of 10 days

Secondary Outcomes (4)

  • Volume of exsudates coming from the drain daily

    Maximum of 10 days

Study Arms (2)

Treatment group

EXPERIMENTAL

Autologous glue will be prepared from the patient's own blood with RegenKit®-Surgery device and applied per-operatively by spraying in the undermining region space between fascia and skin.

Device: Autologous glue

Control group

NO INTERVENTION

Patient from the control group will undergo abdominoplasty according to an identical procedure, but without application of autologous glue or any other treatment product before wound closure.

Interventions

Patients will undergo abdominoplasty according to the procedure routinely used in the Department of Plastic, Reconstructive and Aesthetic Surgery of HUG. At the end of the procedure, patients assigned to the experimental group will be additionally treated with an application of autologous glue prepared with RegenKit®-Surgery in the undermining region space between fascia and skin, just before closure of the surgical wound.
