The Use of Topical Anaesthetic in the Banding of Internal Haemorrhoids

Summary

The investigators' aim is to assess if they can complete a study measuring the effect of local anaesthetic gel (Instillagel) on reducing pain experienced by patients undergoing a common treatment for haemorrhoids (piles). This treatment is called rubber band ligation and is commonly performed in the investigators'clinics.
