GASTRIC TRANSIT TIMES Percentage of Patients with Gastric Transit Times of Four Hours Control Crohn's Disease Ulcerative Colitis

As can be seen from Table II, emptying of the stomach in ulcerative colitis may be delayed. Although some patients were investigated in the active phase of their illness by no means all were toxic and in the main they were longstanding cases. In addition small intestine transit time is slow, but since in only five of eight of this group was it possible to complete the investigation due to the prolonged delay in the stomach of three, further studies of small intestinal transit are needed for confirmation. Should this distinction between the two disorders be substantiated by further study, the alimentary transit time might provide a clinical means of differentiating between Crohn's disease and ulcerative colitis.
