The Effect of a Local Injection of a Platelet Concentrate on Infection and Healing of Surgical Wounds
The Effect of L-PRP on Wound Healing and Wound Infection After Pancreaticoduodenectomy / Whipples Surgery
The purpose of this project is to investigate whether a combination of a local injection of platelet rich plasma (PRP) combined with a daily supplement of vitamin C, zinc, L-arginine, as well as high protein diet (1.5 g of protein per kilo body weight per day) can promote tissue healing in patients undergoing open upper-abdominal surgery.
Primary endpoint is cases of wound infection and secondary endpoints are time of tissue regeneration (days), judged by traditional clinical observation and experimentally assessed by ultrasound.
The experiment is performed as a parallel two-armed, randomized, controlled trial.
A total of 40 subjects will be included in the trial i order to ensure the power of the study, despite a drop off of up to 25%.

Arms and Interventions
Participant Group / Arm |
Intervention / Treatment |
---|---|
Experimental: Leucocyte - Platelet rich Plasma and Dietary Supplements
An application of an autologous platelet concentrate (20 ml). This is injected once, locally in the muscle after closure of the inner fascia and before closure of the outer fascia. A daily dietary supplement of Vitamin C, Zinc and L-Arginine. Provided from POD2-3 until POD30 |
Autologous L-PRP are studied regarding it's accelerating effect on tissue repair.

What is the study measuring?
Primary Outcome Measures
Outcome Measure |
Measure Description |
Time Frame |
---|---|---|
Number of patients with wound infection assessed by traditional clinical observation of the cicatrice
Time Frame: From date of surgery until the date of first documented event of infection or date of death from any cause, whichever came first, assessed up to 30 days .
|
Infection are defined as a collection of pus in the wound that require revision. It is assessed by observation from the hospital staff. |
From date of surgery until the date of first documented event of infection or date of death from any cause, whichever came first, assessed up to 30 days .
