Purpose of the study
Treatment
Allocation to intervention
Randomised controlled trial
Procedure for enrolling a subject and allocating the treatment (allocation concealment procedures)
Included patients will be randomized to procedures either with or without local
anaesthetics. The randomization assignment is concealed in the form of sealed
envelopes located with the suction banding device and is only revealed to the
clinician just prior to the procedure commencing.
Methods used to generate the sequence in which subjects will be randomised (sequence generation)
Randomisation is generated by computer and the code is entered into the sealed
envelope described above
Masking / blinding
Blinded (masking used)

Summary
Brief summary
Symptomatic Haemorrhoids are a commonly encountered in the colorectal clinic.
Rubber band ligation is a simple treatment that can be performed easily in the
office with minimal equipment. However, pain is common following banding
and is sometimes associated with vasovagal symptoms. There have been some
reports of using local anaesthetics in banding to reduce post-procedure pain but
the results were conflicting. The purpose of this study is to prospectively verify
the efficacy of local anaesthetic injection in reducing the pain associated with
using our present technique of suction banding. The prospectively collected data
will also be examined for possible contributing factors to patients’ pain
experience following banding.
