Pilonidal Sinus Disease: Preliminare Study

"In all interventions, the patients were placed in prone position on operating table with the gluteal line opened wide by adhesive patches; after skin disinfection, dimension and extension of cystic disease was studied by injection of hydrogen peroxide through superficial skin orifice. The same procedure was performed: an elliptical incision on midline around the sinus was made and the sinus was excided laterally and in depth on healthy tissue, down till the pre-sacral fascia: this common approach was made both using scalpel and electrosurgery in the two groups. During dissection and excision, in each group were measured and recorded the temperatures developing, both on the section surface using an infrared thermometer and thermal imaging camera, and deeper until 1 cm from the section frontline using a immersion thermometer sealed by a steri-drape to guarantee the sterility on surgical field. In this group excision was carried out with diatermocoagulation"

"the position and preparation of the patient on the operating table were the same as in the hot group, while the excision procedure performed with knife"
