Pancreas secretes digestive enzymes including amylase, lipase and trypsin according to the diet intake. Simultaneously, it secretes insulin, glucagon, gastrin and other hormones to help motility, blood sugar levels to organize total body nutrition. Human cannot live without its exocrine and endocrine function. If the endocrine function is impaired, diabetic condition is rationally treated by insulin by measuring blood glucose level. Exocrine function assessment, however, is only possible using classical fecal fat measurement, fecal chymotripsin or elastase I concentration or pancreatic functional diagnostic test. These assays are cumbersome and requires 24 hrs fecal collection or uurine collection. 13C is stable, non-radioactive isotope that can be incorporated into various compounds. We can measure the metabolism of such 13C incorporated compounds by measuring expiratory output of 13CO2. Most frequently used assay is expiratory 13C assay for Helicobacter pylori. The patients intakes the reagent and inflates the bag 15-20 min later to see if HP exists or eradicated.
It is already known that 13C incorporated fatty acids and amino acids are digested by pancreatic enzymes and finally metabolized to expiratory 13CO2. The measurement of expiratory 13CO2 is know to be useful as a pancreatic function assay (Swart GR, Digestion 1997; 8: 415-420, Nakamura H, Surgery 2009; 145:168-175). Breath ID is a realtime expiratory 13CO2 moniter, that is used in clinical situation in the Europe and United States not only for HP assay but also for measurement of liver function, pancreatic fuction and gastric emptying.
This research is aimed to establish the measurement of pancreatic fuction especially for chronic pancreatits and state after pancreatectomy using Breath ID and 13C incorporated fatty acids and amino acids, resulting in a better patient management.
