Sorbact TM: Effect of a Microbial Binding Dressing on Wound Healing After Pilonidal Sinus Excision (SORKYSA)

This study is currently recruiting participants. (see Contacts and Locations)

Sinus pilonidal concern 26/100 000 young adults. It manifests after puberty, presenting as an acute abscess in approximately 50% of patients or as a discharging painful sinus. Patients may experience lengthy healing times resulting in considerable morbidity and disruption to a young adult's life. Eradication of pilonidal sinus is based on a wide surgical excision and at the end of the procedure, the wound is dressed with an alginate dressing (Algosteril®).

The objective is to show a better efficiency of Sorbact TM (trademark) dressings compared to Alginates that are standardized dressings after pilonidal sinus excision during a period of 75 days. The main objective is to show a difference of 20% of wounds completely healed in 75 days between the two types of dressing: 50% of wounds healed with Algosteril TM compared to 70% of wounds healed with Sorbact TM.

Arms Assigned Interventions
Active Comparator: Algosteril TM
Calcium alginate dressings are made from seaweed. Calcium alginate dressings form a natural gel of the exudates against the healing tissue that keeps it moist and supple, aiding in healing and tissue growth. In addition, this gel material forms a natural barrier to bacteria that may complicate healing with secondary infections of the wound. Alginates are the reference of dressing after sinus pilonidal excision.
Device: Algosteril TM
Experimental: Sorbact TM
DACC (dialkylcarbamoyle chloride) is a main component of the bacterial binding wound dressing: Sorbact. DACC is a hydrophobic fatty acid derivative that can be used to coat dressing materials, resulting in a dressing with highly hydrophobic pathogen binding properties. This is a primary wound interface dressing and is effective when in close contact with the wound bed in a moist environment.
Device: Sorbact TM
