AIM: Rubber band ligation is a common office procedure for the treatment of symptomatic haemorrhoids. It can be associated with pain and vasovagal symptoms. The effect of local anaesthetic use during banding was studied. METHOD: A single-blinded randomised controlled trial was carried out in the colorectal outpatient clinic. Patients presenting with symptomatic haemorrhoids suitable for banding were prospectively recruited and randomised to undergo the procedure with local anaesthetic or without (control). Submucosal bupivacaine was injected immediately after banding just proximal to the site. Vasovagal symptoms were assessed at time of banding and pain scores (visual analogue scale) were recorded at the conclusion of the procedure, after 15 minutes, and on leaving the clinic. RESULTS: Seventy-two (40 local anaesthetic injection [Group 1]; 32 no injection [Group 2]) patients were recruited. The mean ages were 50 and 54 years respectively, the median duration of symptoms was 12 months in each group and the median number of haemorrhoids banded was three in each group. The mean pain score on leaving the clinic was 2.6 [95% CI 2.1, 3.1] in Group1 and 4.1 [95% CI 3.3-5.0] p=0.04) in Group 2. There were no complications related to local anaesthetic use. No significant difference in vasovagal symptoms was found (p=0.832). CONCLUSION: Local anesthetic injection at the time of banding is simple and safe. It may reduce patient discomfort following banding of haemorrhoids. © 2012 The Authors. Colorectal Disease © 2012 The Association of Coloproctology of Great Britain and Ireland.
