Clinical Guidelines and Expert OpinionsYear
…//… “Segmental colon transit time is useful for differentiating slow-transit constipation from defecatory disorders in patients with chronic constipation”…//… 12023
…//… ”Your child needs a colonic transit study to show if there are any problems with their digestive system” …//…2
…//…”There are no risks to your child linked to taking the pellets needed for this test, and they will pass out of your child in their faeces. They can be flushed away safely”…//…
…//… ”Transit time studies may be indicated in patients with rapid transit diarrhoea”…//…32022
…//… “Our experience is that supplementary investigation of these patients with colon transit time, anorectal manometry, defecography with several examinations, may be of value to better characterize the underlying mechanisms of constipation and thereby improve the possibilities for targeted, albeit experimental treatment”…//…42021
…//… “Colonic transit studies this test is generally reserved for patients who have failed medical therapy, as it may guide further management including consideration of potential surgical interventions”…//…
…//… “Slight differences in performing the test exist between laboratories, with one validated method being the ingestion of 10 radiopaque markers per day for six consecutive days, followed by fluoroscopy imaging on the morning of day 7 to count the remaining markers”…//…
…//… “Colonic transit tests are required to distinguish normal from slow-transit constipation, colonic scintigraphy and ROM can provide initial information to differentiate between diffuse and localized colonic dysmotility and/or evacuation disorders and that the recommended diagnostic approaches are ROM studies and colonic scintigraphy, which are considered the best suited for measurement of CTT”…//…6
…//… “When Treatment Isn’t Working. “Intractable” constipation means that the symptom does not respond to the treatments described above. Persons with intractable constipation may see a specialist for diagnostic tests. These may include: Transit time or colonic marker studies: A simple test that measures movement of material through the colon over time”…//…72017
…//… “Colonic transit is suggested if further investigation is needed after physiological testing”…//… “further diagnosis then depends on the presence or absence of colonic transit delay”…//…82017
…//… “12. Statement: Colon transit time is useful for differentiating between the subtypes of defecatory disorders and slow transit constipation in patients with chronic constipation. Grade of recommendation: 1. Level of evidence: B. Experts’ opinions: completely agree (20%), mostly agree (68%), partially agree (8%), mostly disagree (4%), completely disagree (0%), and not sure (0%)”…//…9
…//… “(9) Based on expert opinion, a colonic transit study may be useful to discriminate between functional constipation and functional nonretentive fecal incontinence and in situations in which the diagnosis is not clear”…//…10
…//… “investigations of anorectal manometry, endosonography and colonic transit studies provide noninvasive objective assessment of diagnosis and severity of chronic IC and fecal incontinence in children. This information is valuable for the clinician to plan the treatment strategy and for parents and children to understand the underlying pathophysiology”…//…112013
…//… “Assessments of colonic transit and anorectal function allow patients to be categorized into 3 subgroups (i.e., defecatory disorders, normal transit constipation [NTC], and slow transit constipation [STC]), which facilitates management in refractory patients”…//…12
…//… “CTT with ROM is proposed as one of the screening tests, indicated in patients with severe chronic constipation or alarm symptoms, to evaluate the category or type of constipation”…//…132010
…//… “Application: Measurement of total GITT and segmental colonic transit by repeated marker ingestion followed by a single X-ray is applicable both in clinical practice and in scientific studies of colonic transit”…//…141991
