| [ Summary ] |
Coordinated maneuvers between left hand operation with the control unit, and right hand movements with the tip of the scope are basic and important for insertion techniques in the transverse colon. Insertion procedures are divided into those regions; from the splenic flexure to the middle portion of the transverse colon, from the middle portion of the transverse colon to the hepatic flexure, and the hepatic flexure. Changes in posture are sometimes helpful; from the supine position to the right lateral decubitus, or from the right lateral decubitus to the supine position, and from the supine position to the left lateral decubitus position. Abdominal manipulation and a sliding tube are effective for keeping the sigmoid colon straight. Abdominal pressure is administered to prevent the elongation of the sigmoid colon or the transverse colon. Sliding tubes are used for straightening the sigmoid colon. Main points related to insertion techniques in the transverse colon are preventing elongation of the sigmoid colon and shortening of the transverse colon. Change in posture, use of abdominal pressure and sliding tubes, and deep respiration are important subsidiary measures. |
