BACKGROUND: Patients with inflammatory bowel disease (IBD) in remission frequently experience symptoms resembling irritable bowel syndrome (IBS). In IBS altered motility and visceral sensitivity are found throughout the whole gastrointestinal tract. We aimed to study chemospecific antroduodenal sensitivity in IBD patients. METHODS: Antroduodenal manometry was performed in 10 IBD patients in remission and 13 controls. Small volumes of nutrients and acid were administered intraduodenally. Motility variables and sensation scores were compared before and after each infusion. RESULTS: Acid and lipid infusion decreased the number of antral pressure waves in both groups (p < 0.05). After acid infusion the number of duodenal pressure waves in the sideholes just distal to the infusion port increased in IBD patients compared to the controls (p < 0.05). Lipid infusion increased the number of duodenal propagated pressure waves in both groups, but in controls they were also increased over longer distances (p < 0.005). None of the infusions significantly affected the sensation scores. CONCLUSION: Subtle alterations in chemospecific responses to lipids and acid in IBD patients in remission were observed, affecting duodenal motor activity but not duodenal perception. These changes are indicative of changes at the chemoreceptor level in the duodenal wall in this patient group.
