Purpose of the study
Treatment
Allocation to intervention
Randomised controlled trial
Procedure for enrolling a subject and allocating the treatment (allocation concealment procedures)
Allocation is concealed. The gastrografin and placebo will be packaged in identical 100ml bottles and each labelled with a study identification number, and successively registered patients will be allocated the next bottle in the sequence.
Methods used to generate the sequence in which subjects will be randomised (sequence generation)
Patients will be randomly allocated to gastrografin or placebo on a 1:1 ratio. Randomisation will be blocked over time, and the list giving randomisation and study identification numbers will be provided to the pharmacy by the statistician.
Masking / blinding
Blinded (masking used)
