Sacrococcygeal local anaesthesia versus general anaesthesia for pilonidal sinus surgery: a prospective randomised trial

Abstract

Sixty patients scheduled for pilonidal sinus surgery were prospectively randomly assigned to receive general anaesthesia or sacrococcygeal local anaesthesia with a newly-described technique. Patients in the general anaesthesia group spent more time in the operating theatre and recovery room than did those in the local anaesthesia group (p < 0.05). Two thirds (67%) of the patients in the local anaesthesia group left hospital on the day of surgery compared to only 17% of patients in the general anaesthesia group (p < 0.05). Visual analogue scale pain scores performed during the 3-day follow-up period favoured the local anaesthetic technique (p < 0.05). Postoperative analgesia requirements were greater in the general anaesthesia group than in the local anaesthesia group (p < 0.05). The majority of patients and surgeons expressed satisfaction with local anaesthesia. Sacrococcygeal local anaesthesia appears to be a successful alternative to general anaesthesia for pilonidal sinus surgery.
