Ultrasonographic screening (US) has been reported to be able to detect thickening of the colonic wall. We used a miniature ultrasonicprobe system (MUS) in the colonoscopic examination of patients with ischemic colitis, transient type (IC). Four of these patients were examined twice, first at onset and again in the healing stage, 5 to 8 days after onset. The following results were obtained when thickening of the colonic wall was thus studied with this system.
1. MUS detected 4.0 to 8.0 mm of thickening in the colonic wall.
2. Most thickening occurred in the submucosal layer (SM).
3. In four patients, the thickening of the SM decreased as recovery progressed, though change in thickness of the mucosal and proprius muscle layers was not remarkable. In patients with IC, therefore, the thickening of the colonic wall detected by US was, in fact, thickening of the SM, which was considered edematous.
