Brief Summary
Review the sponsor-provided synopsis that highlights what the study is about and why it is being conducted.
Detailed Description
Dive into the extended narrative that explains the scientific background, objectives, and procedures in greater depth.
Colonoscopy withdrawal times are a critical element in determining quality of colonoscopy; however, few studies have evaluated specific factors that may influence the duration of withdrawal, and specifically short withdrawal times. Other factors affecting polyp detection rate, one element of quality of colonoscopy, also need further study.
Objective:
To identify factors associated with withdrawal time, inappropriately short withdrawal times, and polyp detection rate during colonoscopy.
Design:
Data were prospectively collected (05/08-06/09) on 802 colonoscopies conducted by 9 blinded endoscopists, including patient age and sex, indication, colonoscope insertion and withdrawal time, biopsies performed, number/size of polyps and method of resection, bowel preparation quality, time of day, day of week, endoscopist, position of the procedure within the endoscopist's slate, and call status of the endoscopist.
Setting:
This study was conducted at a single tertiary care hospital, St. Paul's Hospital, in Vancouver, British Columbia.

Study Groups
Review each arm or cohort in the study, along with the interventions and objectives associated with them.
Patients undergoing colonoscopy
Data was collected on all adult patients undergoing outpatient colonoscopy at St. Paul's Hospital from May 2008 to June 2009. Exclusion criteria were prior colon resection and repeat colonoscopy for the purpose of endoscopic therapy for known lesions.
No intervention
Colonoscopies were conducted as per the endoscopist's usual practice. No change in protocol was expected.
