[The role of segmental transit time in the large intestine in the diagnosis of severe constipation].
Segmental small and large bowel transit time of 25 healthy volunteers have been studied, as a control group, by means of radio-opaque markers prepared and administered according to an original method. The same study has been subsequently carried out on 37 patients suffering for chronic non organic constipation. The resulting data, though poorly homogeneous, may however, be plotted in 8 classes; each class groups subjects presenting very similar segmental transit time whose changes are less than 4 hours. The first class gathers the 8.1% of the cases, presenting in increased small bowel transit time; the patients of the second class (5.4%) has resulted affected by "right colon constipation syndrome"; another 5.4% of patients, plotted in the third class have shown a permanence time of the markers in the transverse colon of about 190 hours, while the 10.8% fourth class and the 16.2% fifth class have presented a 97 and 150 hours' one respectively. The patients of the sixth class (21.6%) have shown long lasting permanence of markers in the left colon and in the rectum. The 13.5% of cases, gathered in seventh class, has shown an increased transit time through the whole colon, while at last the eight class (19.0% of patients) has resulted affected by dischezia. The described method has thus revealed useful in the study of bowel segmental transit time from a topographic diagnostic point of view.
