Use of the triolein breath test in alcoholics with liver damage.
The triolein breath test (TBT) is a simple, noninvasive technique for the evaluation of steatorrhea. However, because it depends on intermediary hepatic processes, and because both liver damage and pancreatic dysfunction often co-exist in the alcoholic, the overall usefulness of the test in patients with liver injury was reassessed. We found that even in the absence of steatorrhea, a majority of patients with advanced liver injury (alcoholic hepatitis, cirrhosis, or both) had abnormal TBT results that failed to correct with pancreatic extract. In contrast, patients with less severe lesions (steatosis) had results that were not significantly different from those in normal controls. Inasmuch as the abnormal TBT results in patients with advanced alcohol-induced lesions did not correct with pancreatic extract, the test may not accurately differentiate pancreatic from nonpancreatic steatorrhea in some alcoholics.
