Summary

Diverticulitis is an extremely common digestive disease particularly found in the large intestine in elderly patients and develops from diverticulosis. Diverticulosis is characterized by the formation of pouches (diverticula) that bulge to the outside of the colon, through areas of weakness in the colonic wall. Inflammation (diverticulitis) results if one of these diverticula becomes infected and / or obstructed. It is commonly accompanied by obvious or microscopic perforation, ranging in severity from a single, mild, acute attack of diverticulitis to more severe attacks characterized by abscess formation, occasionally resulting in chronic complications such as obstruction and fistula formation. After an episode of diverticulitis many patients develop changes in bowel openings, from diarrhoea and constipation, and many patients have abdominal pain and a symptom complex that resembles Irritable Bowel Syndrome (IBS).

According to available guidelines, treatment of symptomatic, but uncomplicated, diverticular disease aims to reduce the frequency and severity of diverticular related symptoms (abdominal pain, bloating, alterations in bowel habit) and to prevent complications. Different agents have been proposed, such as bulking agents, antispasmodics, and nonabsorbed topical antibiotics, 5amino acid preparations but these measures are unproven or controversial. It is thought that intestinal bacteria may play a significant role in the symptoms of post-diverticulitis.

The investigators have recently shown that a probiotic (Symprove) reduced the symptoms of IBS significantly in comparison with a placebo in a double-blind randomized trial and without side effects (paper in preparation). Because the symptoms in IBS and post-diverticulitis are so similar the investigators propose a double-blind placebo controlled trial of Symprove in patients with problematic diverticulitis. Patients will be recruited from a dedicated diverticulitis clinic using standard exclusion criteria. This is a 90 day symptom based trial using accepted outcome measures. If successful the results will have widespread implications for treatment of diverticular disease.
