686 Nuclear Transit Scintigraphy (Nts) - An Evolving Role from Diagnostic to Monitoring Tool in Children With Chronic Constipation

Purpose Nuclear transit scintigraphy (NTS) is a relatively new investigation for children with intractable chronic constipation. Three patterns of colonic transit were identified: normal, slow and rapid colonic transit. We aimed to determine the use of NTS over the last 12 years at a tertiary institute. We hypothesised that NTS has evolved from a diagnostic to a monitoring tool. Methods NTS were reviewed retrospectively (1999–2011) and characterized based on 3 different colonic transit patterns with further division into a new/repeat study (Ethics30059A). Statistical analysis was performed with Chi-square test to examine the effect of change; p
