| [ Summary ] |
The endoscope position detecting unit (UPD) is an innovative new system, with which endoscopists can see an image of the scope at the time of insertion. We examined the insertion pattern of twenty five screening colonoscopy cases using UPD, and referred to the usefulness of UPD in difficult insertion cases. The patterns of insertion were divided into the pattern with straight insertion (14 cases, 56%), the pattern with extension with the top of the sigmoid colon (7 cases, 28%), the pattern with loops in the sigmoid colon (3 cases, 12%), and the pattern with adhesions in the sigmoid colon (1 case, 4%). It was suggested that UPD was highly useful for colonoscopic insertion in difficult cases, with patterns of extension or loops in the sigmoid colon. |
