title: Perianal block for ambulatory hemorrhoidectomy, an easy technique for general surgeon.
abstract: BACKGROUND
  Hemorrhoid surgery is mostly being performed as an inpatient procedure under general or regional anesthesia. However, there was a trend toward performing anorectal surgery in an ambulatory setting utilizing local anesthesia.
  
  
  OBJECTIVE
  To propose an easy technique of perianal block for ambulatory hemorrhoidectomy.
  
  
  METHODS
  Between January 2004 and June 2007, 61 patients underwent hemorrhoidectomy under local anesthesia. Lignocaine with adrenaline was injected into the perianal area with an easy technique.
  
  
  RESULTS
  Sixty-one patients with a mean age of 41 years underwent ambulatory hemorrhoidectomy. The mean operative time was 21 minutes. Almost all patients preferred to go home, 5-200 km away from this hospital, taking 20 minutes to 4 hours on transportation.
  
  
  CONCLUSIONS
  An easy technique of perianal block provides availability of performing ambulatory hemorrhoidectomy under general surgeons' hands.
