Brief summary
After abdominal surgery there is a period of unavoidable dysfunction of the gut. During this
time patients are often unable to eat and drink, and do not pass any flatus or stool. Though
this resolves within a few days for most, there are a significant number (around 30%) who go
on to have a prolonged period of this dysfunction known clinically as postoperative ileus. It
has been clearly shown that this group of patients have worse health outcomes and spend a
longer time in hospital.

The aim of this study is to trial a drug - gastrografin - in the management of prolonged
postoperative ileus. Gastrografin is safe, economical, readily available, and has been used
with great success in the similar condition of bowel obstruction. It is predicted that
gastrografin will shorten the duration of a prolonged postoperative ileus, thus affording
affected patients a better outcome from surgery.
