Brief Summary:
Radionuclide scintigraphy is the gold standard technique to interpret OCTT but there is no normative data available for its interpretation in Indian population. Previous studies to determine OCTT have all been done with LHBT, which has many limitations. Besides there are few small comparative studies between scintigraphy and LHBT, that too not in Indian population. The aim of this study is to validate LHBT to measure OCTT compared with scintigraphy and to standardize the normal OCTT in healthy individuals

Intervention Details:
  • Diagnostic Test: 99mTc Scintigraphy

    After fasting for at least 8 to 12 hours, standardized meal mixed with 99mTc-sulfur colloid radiolabeled test will be administered as quickly as possible, optimally within 10 min. Imaging will be obtained with Siemens SYMBIA E dual head (SPECT) scanner in a format of at least 128 x 128 pixels. Anterior and posterior planar images (or a single left anterior oblique image) with the distal esophagus, stomach, and proximal small bowel in the field of view will be obtained for 1 min immediately after ingestion of the test meal and repeated images will be obtained in the same projections with 2 min static images at hourly intervals up to 6 h and at 24 hours as was used for the initial images.

    Next day LHBT will be performed after at least 12 hours of fasting. Following administration of test substrate (Lactulose 10 grams) with one cup of water, breath samples will be analyzed for hydrogen every 15 minutes for 1 hour followed by every half hour for next 2 hour with LACTOFEN 2 device.

    Other Name: Lactulose Hydrogen Breath test

Primary Outcome Measures :
  1. Oro-caecal transit time (OCTT) using lactulose hydrogen breath test (LHBT) and scintigraphy study. [ Time Frame: six months ]
    LHBT is the commonly used test for OCTT, but it has fallacies, since it itself increase intestinal motility, so this study aims to validate LHBT with scintigraphy which is the gold standard test.

Secondary Outcome Measures :
  1. Normative data for OCTT using nuclear scintigraphy in healthy indian population. [ Time Frame: six months ]
    There is no reference values for nuclear scintigraphy in healthy indian patients. The study will help generate data to give reference values for OCTT using scintigraphy.
