BackgroundAlthough the fecal elastase-1 test is a satisfactory pancreatic exocrine function test, breath tests that use stable isotopes have been developed recently as alternatives. We evaluated the usefulness of a 13C-labeled mixed triglyceride breath test for assessing pancreatic exocrine function after pancreatic surgery.MethodsThe breath test and the fecal elastase-1 test were performed on 7 healthy volunteers, 10 patients with chronic pancreatitis, and 95 patients after pancreatic surgery. The breath test was analyzed with isotope ratio mass spectrometry and the cumulative recovery of 13CO2 at 7 hours (% dose 13C cum 7h) was calculated. The fecal elastase-1 concentration was determined immunoenzymatically.ResultsBoth the fecal elastase-1 concentration and the % dose 13C cum 7h of chronic pancreatitis patients and pancreatic resection patients were less than those of healthy volunteers. In all subjects, % dose 13C cum 7h correlated with the fecal elastase-1 concentration (n = 112, R2 = 0.14, P < .01). Accuracy rates for clinical symptoms, including clinical steatorrhea, for the fecal test and the breath test were 62 and 88%, respectively.ConclusionThe 13C-labeled mixed triglyceride breath test might be more useful than the fecal elastase-1 test for evaluating pancreatic exocrine function after pancreatic resection.
