title: [Oxalic acid resorption in patients with resection of the small intestine, jejunoileal bypass, Crohn disease and chronic pancreatitis].
abstract: The enteric absorption of oxalic acid with 14C-labelled oxalic acid was determined in patients with small bowel resection, jejunoileal bypass, Crohn's disease and chronic pancreatitis in comparison to the control group. Extreme hyperoxaluria were found in small bowel resections above 100 cm, after bypass operations and in ileocolitis Crohn with signs of clinical activity. Small bowel resections and relapses of Crohn's disease increase the absorption of oxalic acid. The significance of 14C-oxalic acid absorption test is the recognition of enteric hyperoxaluria.
