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

Summary
Brief summary
Malignant bowel obstruction (MBO) occurs when the bowel (gut) becomes blocked due to cancer. When the bowel is blocked, symptoms such as pain, nausea and vomiting occur. Doctors will try to relieve the blockage with surgery and control the cancer with chemotherapy or radiotherapy, wherever possible. If these treatments cannot be used, medicines can be given to decrease symptoms so that people feel better. In some cases the bowel may become partially unblocked and start working again.
In people where the cause of the bowel blockage is not cancer, a drug called gastrografin has been shown to help unblock the bowel faster. Gastrografin is therefore now commonly given to these people. At the moment we do not know whether gastrografin will help unblock the bowel when the cause is cancer. The reason for carrying out this trial is therefore to help us try and find out whether the addition of gastrografin to the other medicines that we use to control symptoms, will help get the bowel working, when the cause of the blockage is cancer.
