Trendelenberg Versus Left Lateral Position for Colonoscopy

NCT02519686 | Completed DMC

• 1 other identifier: 201504136
• Study Type: observational
• Target: 150
• Locations: 1 country
• Sites: 1

Brief Summary

The purpose of this study is to determine if the trendelenberg (TD) position (position in procedures that involves placing the patient at an angle so that their head is lower than their feet on the procedure bed) in select patients undergoing colonoscopy is superior than the left lateral (LL) position (patient laying on their side, traditionally used for colonoscopies) in terms of decreasing time necessary to pass the colonoscope through the left colon, and decreasing the difficulty of the procedure.

Conditions

Colonic Diseases

Outcome Measures

Primary Outcomes (1)

• Cecal insertion time

  The time from scope insertion to the cecum

  intraoperaive

Study Arms (2)

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)
