New insertion technique in colonoscopy, forming N-loop and using a stiffening cord.
New insertion technique in colonoscopy with a middle length colonscope which is easy to be handled and without guidance of fluoroscopy was reported. Forming a small N-loop at the sigmoid colon, it was easy to pass the sigmoid colon where is one of the most difficult points to pass through. Further, using a differing cord, the sigmoid colon and the transverse colon were easily straightened and no more loop was seen. With this technique, ileocecal area was observed in 26 of 30 cases (86.7%) and its average time for the insertion required only 17.4 minutes. Therefore, with this technique ,it is emphasized that we can easily observed almost all parts of the colonic mucosa and also terminal ileum without the fluoroscopic control.
