This is a protocol for a Cochrane Review (Intervention). The objectives are as follows:

To determine the reliability of oral water soluble contrast media and follow up abdominal radiographs in predicting the success of conservative treatment in resolving inoperable malignant bowel obstructions with conservative management.

To determine the efficacy and safety of oral water soluble contrast media in reducing the duration of obstruction and reducing hospital stay in people with malignant bowel obstruction.
