Pilonidal sinus disease is a chronic acquired disease leading to significant morbidity and healthcare costs in young man and women. Despite different treatment methods, the disease relatively often leads to postoperative complications and recurrence.(8). Advantages of mini-invasive techniques include: quicker recovery and earlier return to work and high patient satisfaction. Randomized studies are rare and this applies especially to newer mini-invasive techniques. The purpose of the investigators prospective study is to randomly compare the mini-invasive laser ablation technique to the mini-invasive fibrin glue treatment in pilonidal sinus disease surgery.

This is a multicenter study comparing two mini-invasive treatmnet options in pilonidal sinus disease. The study is carried out in four hospitals in Uusimaa county of Finland (Jorvi hospital, Porvoo hospital, Lohja hospital and Hyvinkää hospital). Patients, who are 18 or above, with a symptomatic primary pilonidal sinus disease are eligible for the study. On the day of surgery, the patient is randomly assigned to one of the two surgery groups. The main variable of our study is the healing rate at 2 months after surgery. Other variables to be studied are: postoperative complications, length of sick leave, time for returning to everyday life, recurrence rate and the effects of PSD and PSD surgery on the patient's quality of life. A cost analysis will be performed. Risk factors such as overweight, pubic hair, smoking and associated diseases such as diabetes will also be analyzed. According to the power calculation, the investigators need 94 patients in each group to ensure the success of the study.
