• Research summary

  Our study is a double blinded, randomised controlled study to assess the efficacy of 2% lignocaine local anaesthetic gel instilled into the rectum following outpatient banding of piles (haemorrhoids). Sixty patients undergoing outpatient banding of haemorrhoids will be randomised to receive either 11ml of 2% lignocaine local anaesthetic gel instilled into the rectum following banding, or 11ml of placebo lubricant water based gel.This study is designed to answer the question "Does local anaesthetic gel introduced into the rectum following outpatient banding of haemorrhoids improve the post procedure pain experienced by the patient?" and in addition, "Does local anaesthetic gel introduced into the rectum following outpatient banding of haemorrhoids improve other symptoms experienced by the patient? Some colorectal surgeons instil local anaesthetic gel into the rectum following the banding procedure. The duration of action of the local anaesthetic gel is several hours (1-8 hours). It is thought that the abolition of any initial pain may prevent the subsequent anal spasm and thus prevent discomfort over a longer time period than the duration of action of the gel. Although studies have shown a benefit of injected rectal local anaesthetic, there have been no studies to assess the effectiveness of this use of local anaesthetic gel.The study will be performed at the Royal Sussex County Hospital, Brighton and the Princess Royal Hospital, Haywards Heath.
