|Condition or disease|
The colonoscopists will be asked to rate their prediction of difficulty of the procedure prior to the colonoscopy and to rate the ease of procedure after the colonoscopy. The clinical experience of the study investigators is that TD positioning is superior to LL positioning in patients with risk factors for having a difficult colonoscopy (thin women; those with diverticulosis- small bulging pouches present in the colon; or prior pelvic surgery).
Patients with risk factors for difficult colonoscopy will be randomized to undergo colonoscopy while positioned in the TD position or the LL position during advancement of the colonoscope through the sigmoid colon. The sigmoid colon is a section of the colon, proximal to the rectum, that is curved. The sigmoid colon is a normal component of GI tract anatomy, although due to it's shape, especially with the risk factors listed previously; can cause challenges to inserting the colonoscope.

Trendelenburg position maneuver
Trendelenburg (TD) positioning (supine with head tilt-down) is used in abdominal and gynecological surgery as well as during colonoscopy to allow better access to the pelvic organs, as gravity pulls the bowel out of the pelvic cavity and the rectosigmoid angle straightens.
Left lateral position maneuver
Left Lateral (LL) position (patient laying on their side, traditionally used for colonoscopies)
- Cecal insertion time [ Time Frame: intraoperaive ]The time from scope insertion to the cecum
