Influence of extrapancreatic digestive disorders on the indirect pancreatic function test with fluorescein dilaurate.
The detection rate of pancreatic disease using the indirect pancreatic function test with orally administered substrate fluorescein dilaurate (FDL) was evaluated in 290 patients. The sensitivity of the test was 84% in chronic pancreatitis (99 patients). Results were abnormal in all 5 patients with advanced pancreatic cancer and in 3 of 19 patients tested after a single episode of acute pancreatitis. The specificity of the FDL test was 89% when healthy subjects or patients with functional gastrointestinal disorders served as controls. However, it dropped to 62% when all patients with different organic gastrointestinal disorders were considered. This decrease could be attributed to patients with subtotal gastric resection and extensive small bowel disease, who were found to have the highest of pathological FDL test results, i.e., 70 and 35%, respectively. Not restricting the oral FDL test to the detection of primary pancreatic disease, in subtotal gastrectomy and extensive small bowel disease this test provides the opportunity to detect secondary pancreatic dysfunction.
