Do Oro‐anal Transit Markers Predict Which Children Would Benefit From Colonic Manometry Studies?

OTT studies may be helpful to predict which children should be referred for CM studies. Normal OTT studies may predict normal colon manometry; however, abnormal OTT studies may not predict abnormalities in colonic manometry in children with chronic constipation. Therefore, patients with slow transit marker studies should be assessed by colon manometry to evaluate colon neuromuscular integrity.
