Right Or Left in COLonoscopy (ROLCOL)? A Randomized Controlled Trial of Right- versus Left-Sided Starting Position in Colonoscopy

Our study reveals that right-sided positioning at the start of colonoscopy results in more comfortable and quicker procedures. Of the factors identified by multiple linear regression to independently have an impact on time to reach the cecum, only starting position is modifiable. Right-sided starting position may therefore be of benefit in colonoscopy, in particular for women and patients who have previously undergone abdominal surgery.
