title: Haemorrhoidectomy by vessel sealing system under local anaesthesia in an outpatient setting: preliminary experience.
abstract: OBJECTIVE
  This prospective study was designed to assess the feasibility of local anaesthesia for LigaSure haemorrhoidectomy in an outpatient setting.
  
  
  METHODS
  From April 2006 to March 2007, 207 consecutive patients (median age 42, 126 males) with grade III (147) and grade IV (60) haemorrhoids, underwent Milligan-Morgan haemorrhoidectomy with LigaSure under local anaesthesia (lidocaine 1%, mean dose 27 +/- 1.7 ml) in an outpatient setting. Postoperative pain was assessed by a visual analogue scale (VAS).
  
  
  RESULTS
  Two, three and four files were removed in 120, 51 and 36 patients. Mean operative time was 12 +/- 5.2 min and mean blood loss was 3.4 +/- 3.9 ml. The mean postoperative pain scores were 6.2 +/- 2.1 for the maximal pain intensity and 6.1 +/- 2.5 for the pain on defecation. All patients left hospital after surgery within 2 h and 33 (15.9%) required analgesics. They returned to normal daily activity after 12.2 +/- 7.9 days including work (12.1 +/- 7.8 days). The wounds had healed by 32.2 +/- 9.1 days. At a follow-up of at least 6 months, only six cases of major bleeding had occurred and 24 patients had skin tags. The median satisfaction score was +2 (-2 to +3).
  
  
  CONCLUSIONS
  LigaSure haemorrhoidectomy under local anaesthesia in the outpatient setting is safe and effective.
