The aim of this randomized single-blind clinical trial is comparison of pilonidal sinus surgery complications between two methods of local and general anesthesia. A total of 60 patients, meeting eligibility criteria, will be randomly allocated into two equal groups. Local infiltration anesthesia group (n=30)received local anesthesia solution of 20ml:12ml lidocaine 2% , 1ml epinephrine 1/200000 , 6ml bupivacaine 0.5% , 50µg fentanyl (1ml); in sacrococcygeal region. General anesthesia for patients in the GA group will be used with intravenous midazolam 0.02ml/kg and fentanyl 3µg/kg as premedication and for induction from propofol 2mg/kg, atracuriom 0.5 ml/kg. During surgery, anesthesia will be maintained on need by isoflurane MAC 1, 60% nitrous oxide, fentanyl, atracurium and at the end of anesthesia residual Neuromuscular blockade was antagonized with neostigmine 0.05 mg / kg and atropine 0.15 mg/kg. The amount of intraoperative bleeding duration of surgery, operation time and at the recovery in moments of 1, 10, 20 and 30 min respiratory rates, nausea and vomiting, o2 saturation and blood pressure will be recorded.A nurse ( a blinded observer) will assess post-operative pain at 3, 6, 24, 48 and 72 with a visual analogue scale after surgery. The amount and type of analgesic drugs prescribed and the duration of hospitalization after surgery will be recorded at questionnaire. Patients one week and one month after surgery will visit by surgen assistant (A Blinded observer) to assess wound infection, wound seroma and recurrence after surgery.
