    Abstract:
    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.
