Comparison of Laser Destruction of Pilonidal Sinus Disease (SILAC) and Bascom II Procedure.

Surgical treatment witn lateralization of intergluteal cleft is still gold standard for pilonidal sinus disaease. But nowadays minimally invasive treatment methods such as the use of a diode laser (SiLac, Sinus Laser Closure) to obliterate the coccygeal tract are used more often. The aim of the study is to compare a new minimal invasive method (laser treatment) with traditional method ( Bascom II) in terms of recurrence rate, complications and patients satisfaction with results.

Inclusion Criteria:Written informed consentChronic primary or recurrent pilonidal sinus at the remission stage.Presence or absence of secondary orifices.Planned surgical treatment with excision of pilonidal sinus.Location of the orifices should not be less than 1 cm.Location of secondary orifices less 2 cm from the natal cleft.Distance between bilateral symmetrical positions of secondary orifices should not be more than 2 cm.Length of the sinus in the greatest dimension, according to the ultrasound of the soft tissue of the sacrococcygeal region, should not exceed 7 cm.Sinus diameter (width) in the greatest dimension should not exceed 3 cm, according to the ultrasound of the soft tissues of the sacrococcygeal region.Sinus must be located directly under the skin, according to the ultrasound findings.Lack of fixation of the cavity to the coccyx, when evaluating data on pelvic contrast-enhanced magnetic resonance imaging (MRI)____ Non-inclusion criteria1.
