Bentiromide test (BT) has been recently approved in the United States for screening patients with chronic pancreatitis for exocrine insufficiency. A few reports have suggested that the rice flour breath hydrogen test (RFBHT)--i.e., breath hydrogen analysis after rice flour ingestion--may also be useful in diagnosing exocrine pancreatic insufficiency. We conducted this study to compare the diagnostic value of these two tests in chronic alcoholic (n = 14) and nutritional or tropical (n = 6) pancreatitis. False-positive results were not noted with either of these two tests in 12 healthy volunteers. BT was positive in 28.6% of patients with chronic alcoholic pancreatitis and in 16.7% of patients with tropical pancreatitis. In comparison, RFBHT was almost twice as sensitive as BT in detecting insufficiency in patients with alcoholic pancreatitis (50 vs. 28.6%) and four times as sensitive in patients with tropical pancreatitis (66.7 vs. 16.7%). Only one patient in our study had a positive BT but a negative RFBHT. We recommend RFBHT as a simple, safe, and inexpensive test in screening patients for exocrine pancreatic insufficiency.

The PFD test was performed on various pancreatic disease patients. The urinary PABA excretion rate was significantly lower in chronic pancreatitis patients and in pancreatic carcinoma patients than in the controls, but no difference was observed between PABA excretion in the two diseases. After surgery, PABA excretion values of pancreatic carcinoma patients were significantly lower than those of non-pancreatitis non-pancreatic carcinoma patients. This was thought to be caused by the difference in residual anastomosed pancreatic tissues. Mild to severe pancreatitis, fibrosis and/or fat necrosis were seen in the pancreatic tissues of carcinoma patients, but these changes were minimal in non-pancreatitis non-pancreatic carcinoma patients. The PFD test is useful in detecting decreases in pancreatic exocrine functions or measuring the grade of pancreatic disorders in various pancreatic diseases, although it can not be used to differentiate pancreatic diseases.
