Comparison of duodenal and jejunal disaccharidase levels in patients with non ulcer dyspepsia. Tropical Gastroenterology. 2001 Jul-Sep; 22(3): 135-6http://imsear.searo.who.int/handle/123456789/125278AIMS: 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.engDisaccharidases --analysisDuodenal Ulcer --metabolismDuodenum --metabolismDyspepsia --metabolismEndoscopy, GastrointestinalFemaleHumansJejunum --metabolismMaleMiddle AgedComparative Study
