Sample text

The left hand is used to hold the colonoscope control head and the right hand holds the shaft of the endoscope 10 to 20 cm from the anus so that force is transmitted straight up through the endoscope in an attempt to minimize looping. As a general rule, during insertion of the colonoscope, one should insufflate as little air as possible—just enough to see the lumen. As more air is insufflated, the bowel distends and lengthens. This increases patient discomfort and makes it more difficult to advance the colonoscope than it would be in a decompressed colon.

The sigmoid colon is not fixed within the abdomen, and as such can be moved by the effects of the endoscope, air insufflation, or both. As such, minimal air should be insufflated into the sigmoid colon to reduce the risk of forming a loop in the first place. Difficulties in advancing the endoscope through the sigmoid colon are commonly caused by inexperience, diverticulosis, or previous abdominal/pelvic surgery. If a loop develops in the sigmoid colon and reducing the loop does not allow the endoscope to advance, applying abdominal pressure to the suprapubic area is usually enough to assist one in moving the endoscope through the sigmoid colon.

As more air is insufflated, the bowel distends and lengthens. This increases patient discomfort and makes it more difficult to advance the colonoscope than it would be in a decompressed colon. It is important to keep the colonoscope as straight as possible during the entire procedure to prevent excess looping. The endoscope is straightened by withdrawal (pulling back), especially after negotiating a turn. When significant looping occurs, such that the colonoscope will not advance or seems to withdraw when the shaft is advanced into the colon, external compression is needed.
