Comparison of Procedural Sequence in Same Day Consecutive Bidirectional Endoscopy Using Moderate Sedation: A Prospective Randomized Study

The aim of the study is to determine what precolonoscopic measures can be correlated to pain during colonoscopy

The aim of the work is to determine prdictive pre-endoscopic factors for pain during colonoscpy. These factors may be demographic, antrophometric, socio-ecomomic, related to previous medical staus or to anxiety levels.

We will try to find an objective parameter for prdiction of pain during colonoscopy, so pre-procedural intervantion will be applied in order to reduce the pain.
