Serum bile acids and rountine liver function tests in patients with chronic liver disease and cholestasis.

Serum bile acids were measured in 28 patients with established liver disease. The peak serum level after a meal was as sensitive an index of liver disease as a combination of serum bilirubin, aspartate amino transferase, alkaline phosphatase and gamma glutamyl transpeptidase and was more often abnormal than any one of the four tests. Serum bile acid measurements may be of most value in detecting cirrhosis when the activity of disease is minimal.

Comparison of endoscopic forceps biopsies and capsule biopsies in determining disaccharidase activity in the duodenum.

Endoscopic biopsy is an accepted technique for obtaining samples of small bowel mucosa for histological examination. In this study a comparison between endoscopic forceps biopsies and capsule biopsies in estimating disaccharidase enzyme activity in the small bowel was evaluated. Disaccharidase levels on 168 consecutive small bowel biopsies obtained by either endoscopic biopsy or capsule biopsy were reviewed retrospectively. There was no significant difference in enzyme activity in samples collected by either method. Another 18 patients had simultaneous endoscopic and capsule biopsies from the second part of the duodenum. Again, there was no difference in enzyme activity between samples collected by either technique at the same level in the duodenum. The disaccharidase activity in forceps biopsies taken from the second part of the duodenum is equivalent to those obtained by capsule biopsy.
