  • Title: Comparison of duodenal and jejunal disaccharidase levels in patients with non ulcer dyspepsia.
    Author: Rana SV, Bhasin DK, Katyal R, Singh K.
    Journal: Trop Gastroenterol; 2001; 22(3):135-6. PubMed ID: 11681105.
    Abstract:
    AIMS: 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.
