Small intestinal function in chronic relapsing pancreatitis.

Abstract

In a prospective study, several parameters of small intestinal function have been assessed in 20 patients with chronic relapsing pancreatitis with and without steatorrhoea. By and large all routine parameters of small intestinal function were found to be normal. In particular, neither a previously reported high incidence of lactase deficiency, nor D-xylose malabsorption or vitamin B12 depletion was observed. However, there was a high incidence of abnormal 14C-cholylglycine breath tests (40%), suggesting the presence of mild bacterial overgrowth. Occasionally, this condition was associated with diarrhoea and steatorrhoea, thus indicating that steatorrhoea remaining after high-dosage pancreatin supplementation might sometimes be due to bacterial overgrowth.
