    The secretion of trypsin and chymotrypsin into the duodenum in response to secretin and CCK-PZ has been compared with the faecal excretion of the enzymes following similar stimulation in 47 individuals undergoing clinical investigation. The faecal output of chymotrypsin correlated well, but trypsin less satisfactorily, with the secretion of the respective enzymes into the duodenum. The faecal excretion of chymotrypsin following stimulation with secretin and CCK-PZ can therefore be used as an index of pancreatic enzyme-secretory capacity.
