| [ Summary ] | A new magnifying colonoscope made by TOSHIBA is useful for the diagnosis of solar disease. The size and shape of this new magnifying colonoscope are the same as the normal colonoscope. When we found some lesions in a screening, magnifying observation can easily be performed by pushing a button. The magnification rate is sixty times for a 16-inch monitor. In the magnifying mode, the pit pattern of a lesion may be clearly observed even if it had a very small pit pattern like IIIs or V. Case 1: A shallow depressed lesion of the sigmoid colon. The surface is red and smooth (Fig. 3a - c). The IIIs and IIIL pit pattern were observed in the magnifying mode (Fig. 3d, e). Almost all parts of the lesion are limited in the mucosal layer, but they were found to have invaded the mid-submucosal layer (sm2) at only one point (Fig. 3f). Case 2: A shallow depressed lesion with a marginal elevation. There was a deep depression in the shallow depression (Fig. 4a, b). A IIIL pit pattern was observed at the marginal elevation and a VN pit pattern at the deep depression (Fig. 4c, d). The invasion depth was sm1 at a small part of the deep depression (Fig.4e). This new magnifying colonoscope is useful for both screenings and work-ups. |
