BACKGROUND Constipation is a common problem in childhood, and various radiologic methods have been advocated for investigation. Colonic transit time (CTT) has been used in adults to investigate colonic motility, but few studies evaluate this method in children. Data on CTT in the normal paediatric population are scarce. METHODS The colonic transit time was measured in 22 healthy children (med...

constipation isa common clinical problem that can be functional or organic in origin. thiscondition sometimes overlaps with irritable bowel syndrome. initially, theclinician should differentiate between true and false constipation by clinicaland preclinical evidence such as colonic transit time. numerous patients believethat all defecation problems are called constipation and use laxatives with...

The gastrointestinal tract normally functions to move ingested food, in an organized fashion, from the oropharynx, through the stomach, small intestine and colon and into the rectum, from which it can be expelled. The primary function of the colon is to absorb water and electrolytes from the chyme delivered and, thus, determine the frequency, consistency, and volume of stools eliminated. The co...

Determination of normal gastric emptying time and small intestinal transit time are useful in detecting gastrointestinal motility disorders and partial obstructions of the pylorus or small intestine. This study was conducted to evaluate iodixanol as a contrast agent in the gastrointestinal tract in New Zealand White rabbit. Twelve clinically healthy adult rabbits were prepared and kept for two ...

Previous investigations of stress effects on gastric emptying, orocaecal, and colonic transit in rats have produced conflicting results. Here one type of stressor, a 'passive avoidance' situation, was used to investigate its effects on gastric emptying, orocaecal and colonic transit. After the rats had been trained to eat a standard amount of semisolid food, gastric emptying was determined (n =...

OBJECTIVE The assessment of potentially confounding factors affecting colon microbiota composition is essential to the identification of robust microbiome based disease markers. Here, we investigate the link between gut microbiota variation and stool consistency using Bristol Stool Scale classification, which reflects faecal water content and activity, and is considered a proxy for intestinal c...
