Brief Summary

Review the sponsor-provided synopsis that highlights what the study is about and why it is being conducted.

Rationale The cosmetic aspect of scars is a frequent reason for consultation. It plays an important role in patient satisfaction and self-image. Several treatment modalities are proposed for scars with variable success.

Ablative fractional laser treatment is a rather new concept. Many microscopic small laser beams target the dermis in a grid pattern. The vertical columns of skin hit by the laser beams heat up. This thermal effect stimulates the wound healing and potentially leads to a remodeling of the skin structure.

Ablative fractional laser treatment has been used successfully for treatment of pigment changes, wrinkles, acne scars and thermal burn wounds. It has been reported that CO2 ablative fractional laser treatment has a positive clinical effect on various types of scars however this has not been proven yet in a prospective randomized trial. The low morbidity of the treatment and the lack of convincing adapted treatment modalities for various types of scars make this treatment attractive.

That's why the investigators aim with this randomized study to evaluate the clinical effect and the safety of 10 600 nm ablative fractional laser therapy for patients with recent scars due to surgical interventions.

Goal Evaluate the efficacy of three 10 600 nm ablative fractional laser treatments for the above mentioned scars, three months after the last laser treatment, with a prospective randomized intra-patient controlled study.

Study design Prospective single blinded randomized intra-patient controlled study. The study comprises 4 study visits.

Study population The population consists of one group of patients with scars after recent surgical operations. The patients must meet the inclusion and exclusion criteria described in the protocol.

Method The scar will be divided in two equal halves. The two halves will be randomized. One part will not be treated. The other part will undergo three times the 10 600 nm ablative laser therapy with 4 weeks interval between the treatments. The efficacy of the treatment will be evaluated three months after the last treatment with objective and subjective parameters.

Most important study endpoints:

* Evaluation of the efficacy of the treatment. A blinded clinical scar evaluation will be done of the treated and untreated parts with the POSAS scar scale, by a study collaborator and by the patient himself, on a category scale of 0 to 10 (0 = normal skin, 10 = worst scar imaginable), before start and twelve weeks after the last treatment.
* Evaluation of the pain related to the treatment. The pain will be scored by the patient with the VAS category scale from 0 to 10 (0 = no pain, 10 = worst pain ever).
* Evaluation of the side effects of the treatment. A standardized form will be used.
* Evaluation of the global patient satisfaction regarding the treatment.
* Clinical photos, before start and twelve weeks after the last treatment.
