| [ Summary ] | The principle of colonoscopy insertion is "axis holding shortening technique." However, if the sigmoid colon is likely to rise upward and difficult to pass straight by the shaft holding shortening method, it is useful to use abdominal manual compression at 3-5 cm above the umbilicus. This manual compression prevents stretching of the mesentery of the sigmoid colon, either when reaching the SD junction with a sine curve or when drawing an α-loop, so that the patients barely feel the pain. Once the scope reaches the SD junction, do a perfect straight line on the scope. Even if the scope is straightened beyond the SD junction, stretching of the sigmoid colon or drooping of the transverse colon may occur. In such cases, manual compression applied several centimeters above the pubic bone may be helpful. Using this technique, overextension of the scope is avoided, and the force is firmly transmitted to the tip of the scope, thereby, facilitating smooth insertion. | |
