(n=154, 81.1%) divided into normal subgroup (n=84, 54.5%; IQR CTT=26.4 [9.6] hours), outlet obstruction (n=18, 11.7%; 62.4 [15.6] slow (n=52, 33.8%; 54.6 [21.0] hours]. (n=36, 18.9%) (n=8, 22.2%; CTT=32.4 [9.9] 67.8 [34.8] (n=20, 55.6%; 59.4 [62.7]hours).This provided basic pattern with constipation.
