Increased colon transit time and faecal load in irritable bowel syndrome

Figure 1 Colon transit study in an irritable bowel syndrome patient. Patient ingested 24 markers, and an X-ray was acquired at 48 h. From the X-ray, we counted the number of markers in each segment: 2 + 8 + 10 = 20; faecal load score: 2 + 2 + 1 = 5 (see text).

Figure 2 Colon transit study in a healthy control. Subjects ingested the 24 markers for 6 d, and an X-ray was acquired on day 7. From the X-ray we counted the number of markers in each segment: 11 + 6 + 1 = 18; faecal load score: 2 + 1 + 1 = 4 (see text).
