Evaluate the Safety and Diagnostic Advantages of Tilt Down Verses Standard Horizontal Colonoscopy Positioning

Not Applicable

Terminated

Brief Summary: A tortuous sigmoid colon makes colonoscopy difficult. The purpose of this study was to systematically evaluate the diagnostic utility and incidence of adverse events in women using standard horizontal compared to lateral tilt down positioning for colonoscopy.

Detailed Description: This was a prospective, randomized study. Subjects who provide informed consent and present to the offices of Specialists in Gastroenterology for colonoscopy will be randomized in a 1:1 distribution to either left lateral tilt down versus left lateral horizontal positioning to initiate colonoscopy.

Demographic data as well as routine information regarding the colonoscopy was filled out during or at the end of each procedure. In addition, the following parameters were assessed, and compared between groups:

1. Occurrence of complications related or possibly related to the colonoscopy procedure

2. Scope insertion time

3. Pain during and after the procedure

The subjects' participation was limited to the duration of the colonoscopy, which is typically less than 60 min and a follow up by telephone 24 hours later to assess the occurrence of complications.
