The pilonidal cyst will be resected, with the use of a scalpel and then haemostasis will be performed with diathermy.
Alginate dressings with silver and high-G cellulose, which combine increased absorption properties, antimicrobial action and high coherence will be used. The size of the dressings will be 3cm X 45cm and 1 cm cord will be used for filling the wound cavity. Dressings with perimetric adhesive layer from natural materials for latent breathing of the skin with dressing dimensions based on the wound size, will be also placed.
Wound care will be performed in a specific way each time that the dressings will be removed. The wound will be irrigated with normal saline and betadine solution and finally without pressure the trauma will be dried.

Pilonidal Cyst/Fistula

The pilonidal cyst will be resected, with the use of a scalpel and then haemostasis will be performed with diathermy. Alginate dressings with silver and high-G cellulose will be applied to the wound. The size of the dressings will be 3cm X 45cm and 1 cm cord will be used for filling the wound cavity. Dressings with perimetric adhesive layer from natural materials, will be also placed.
During wound care the wound will be irrigated with normal saline and betadine solution and finally without pressure the trauma will be dried.

Alginate Dressings Versus Gauge Dressings After Pilonidal Cyst Resection: Examination of the Quality of Life

Secondary Intention Wound Healing, in Patients Subjected to Surgical Resection of Pilonidal Cyst, Using Alginate Dressings With Silver and High-G Cellulose, Compared to the Use of Simple Gauze Dressings: Examination of the Quality of Life

Postoperative required time for wound healing. Measurement unit: days

Time required for returning to everyday activities. Measurement unit: days

Pain level after surgery, quantified with the use of the Visual Analogue Scale (0-10). Better outcome: 0, Worse outcome: 10. There will be no subscales or total scores.

Number of analgesic pills consumed per day after surgery. Measurement unit: pills per day

Satisfaction level after surgery, quantified with the use of the Visual Analogue Scale (0-10). Better outcome: 10, Worse outcome: 0. There will be no subscales or total scores.

Number of required visits for postoperative wound care for each patient per week.

Trauma secretions leading to extra dressing care. If such an episode occurs, then it will be defined as=1 'YES' If such an episode does not occur, then it will be defined as=0 'NO'

Contamination of the wound trauma. If such an episode occurs, then it will be defined as=1 'YES' If such an episode does not occur, then it will be defined as=0 'NO'

Erythema of the wound. If such an episode occurs, then it will be defined as=1 'YES' If such an episode does not occur, then it will be defined as=0 'NO'

Haematoma of the wound. If such an episode occurs, then it will be defined as=1 'YES' If such an episode does not occur, then it will be defined as=0 'NO'

Disease recurrence rate. If such an episode occurs, then it will be defined as=1 'YES' If such an episode does not occur, then it will be defined as=0 'NO'

Difference in the quality of life of the patient based on the Quality of Life with Chronic Wounds Wounds (Qol) Questionnaire. 17 items in total. Each item quantified with the use of a Visual Ordinal Scale (0='not at all' to 4='very much'). Global score computed by averaging all items. In total 3 subscales calculated by averaging the respective items:
Body: Items #1 to #5. Psyche: Items #6 to #10. Everyday life: Items #11 to #16.

Quality of life of the patient based on the Short Form 36 (SF-36) questionnaire. 36 items in total. The following ordinal scales will be used for the respective items:
1 (Better)-5 (Worse): #1, #2, #20, #22, #34, #36.
1 (Worse)-3 (Better): #3, to #12.
1 (Worse)-2 (Better): #13, to #19.
1 (Better)-6 (Worse): #21, #23, #26, #27, #30.
1 (Worse)-6 (Better): #24, #25, #28, #29, #31.
1 (Worse)-5 (Better): #32, #33, #35. In total 8 subscales calculated by averaging the respective items. Physical functioning: #3 to #12. Role limitations due to physical health: #13 to #16. Role limitations due to emotional problems: #17 to #19. Energy/fatigue: #23, #27, #29, #31. Emotional well-being: #24 to #26, #28, #30. Social functioning: #20, #32. Pain: #21, #22. General health: #1, #33 to #36.

Patient satisfaction regarding the treatment quantified with the use of a Visual Ordinal Scale (1-5). Better outcome: 5, Worse outcome: 1. There will be no subscales or total scores.

Patient acceptance regarding the re-application of the treatment quantified with the use of a Visual Ordinal Scale (1-5). Better outcome: 5, Worse outcome: 1. There will be no subscales or total scores.

There is not a plan to make IPD available.

Blinding will exist at the level of the investigator who will record the data postoperatively. There will be no blinding at the level of the surgeon or the patient.
