BackgroundThe liver produces and secretes bile acids into the small intestine. In the small intestine, most of the bile acids are absorbed in the distal ileum with portal vein transportation back to the liver and resecretion (enterohepatic recycling). Increased spillover of bile acids from the small intestine into the colon (bile acid malabsorption) may affect the secretion of colonic water and electrolytes and result in watery diarrhoea.The aim of this study was to investigate the frequency of bile acid malabsorption and treatment responses to cholestyramine with 75SeHCAT scanning among patients suffering from chronic watery diarrhoea.MethodsThis was a retrospective study that included all patients who received a 75SeHCAT scan over a five-year period (2004–2009).ResultsIn total, 298 patients (198 females, 100 men) with a median age of 42 years (range 16–82 years) were investigated.Bile acid malabsorption (75SeHCAT retention < 15% after seven days) was identified in 201 patients (68%, 95% confidence interval (CI): 62%–73%). Bile acid malabsorption due to ileal dysfunction (Type I) was found in 77 patients, idiopathic bile acid malabsorption (Type II) was found in 68 patients and 56 patients with other conditions had bile acid malabsorption (Type III).Of the 150 patients who were able to take cholestyramine continuously, 108 patients (71%, CI: 63%–78%) reported a positive effect on their bowel habits.ConclusionsBile acid malabsorption is a frequent problem in patients with chronic watery diarrhoea. Treatment with bile acid binders was effective regardless of type and severity.
