Comparison of duodenal and jejunal disaccharidase levels in patients with non ulcer dyspepsia.
OBJECTIVE
This study was conducted to compare the duodenal and jejunal disaccharidase levels in the same individual with duodenal ulcer or non ulcer dyspepsia.


METHODS
Thirty seven patients (duodenal ulcer--11, non-ulcer dyspepsia--26) were included in the study. Endoscopic biopsy samples were obtained from jejunum and duodenum using pediatric colonofibroscope.


RESULTS
Levels of jejunal disaccharidases were significantly higher than the duodenal disaccharidases.


CONCLUSIONS
An estimate of jejunal disaccharidases can be had by multiplication of duodenal disaccharidased by a factor 1.48 for lactase, 1.50 for sucrase and 1.56 for maltase.
