  • Research summary

    Crohn’s is a disease that makes the bowel red, swollen and painful. It is a lifelong disease. Some people get few flare-ups. Other people may have really bad and long lasting symptoms. There is no cure for Crohn’s, but drugs can treat the symptoms. If the drugs do not work surgery may be needed. Whilst surgery can also stop symptoms for a long time, the disease can return. Further drugs and even further surgery may be needed.

    Many surgeons feel that the way the bowel and the tissue containing the blood and other vessels supplying the bowel (the mesentery) is removed and the way the healthy bowel ends are re-joined can affect success of surgery. Two changes to the way surgeons operate have been proposed. One involves taking out more of the mesentery and the other involves doing another type of bowel join. This is known as the Kono-S join. We know that they are safe, but we need to test that they are better than the usual method in stopping further disease.

    We want to ask people if they would let us carry out one or both of these methods. We will then see if they have made the chances of further disease up to one year later. The type of surgery a person has will be decided by chance.

    We also need to see why these new methods may work. Some clues may be found by looking at those who get further disease after surgery and seeing what part of the join the disease has come back to. To try and understand this, for a small group of patients we will also do blood tests and take samples from different bowel areas before and after surgery to see how the immune system is altered after the different operations.
