The Value of the Trendelenburg Position During Routine Colonoscopy: A Pilot Study.

Not Applicable

Completed

• Conditions: Colonoscopy
• Interventions: Procedure: Standard care; Procedure: Trendelenburg position

• Registration Number: NCT01267123
• Lead Sponsor: University of Missouri-Columbia

Brief Summary

Colonoscopy is a procedure commonly performed to screen for colon cancer and to look for and remove colon polyps. It involves inserting a flexible tube, equipped with a video-camera at the tip, through the colon. The insertion process can be difficult in some patients, resulting in an uncomfortable and lengthy procedure.We postulate that raising the foot of the bed so that the stretcher forms a 15 degrees angle with the floor ("Trendelenburg position") may make the colonoscopy easier and more comfortable to the patient.

Detailed Description

Colonoscopy is a procedure commonly performed to screen for colon cancer and to look for and remove colon polyps. It involves inserting a flexible tube, equipped with a video-camera at the tip, through the colon. The insertion process can be difficult in some patients, resulting in an uncomfortable and lengthy procedure. Colonoscopy procedures are typically started with the patient positioned on their left side. If there is later difficulty advancing the colonoscope, the patient is shifted to other positions (e.g. back, right side, prone). We postulate that raising the foot of the bed so that the stretcher forms a 15 degrees angle with the floor ("Trendelenburg position") may make the colonoscopy easier and more comfortable to the patient. This is a position commonly used in gynecologic surgery. This is a pilot project for us to gain experience with doing colonoscopy this way. The enrolled patient will be assigned randomly to 2 groups: one in the standard left lateral position and one in the 15 degree Trendelenberg position. We will be collecting data regarding the procedure from each group in the form of questionnaire and data sheet which will be filled during or at the conclusion of the procedure.

Arm && Interventions

Group	Intervention	Description
Standard care	Standard care	The patient will have colonoscopy in the standard horizontal position
Trendelenburg position	Trendelenburg position	The endoscopist places the patient in 15° Trendelenberg position immediately prior to the initiation of the colonoscopy.

Primary Outcome Measures

Name	Time	Method
The time of the procedure from the insertion of the colonoscope until the cecal base is reached	This outcome is measured when the cecum is intubated during a colonoscopy
