Conditions

Outcome Measures

Primary Outcomes (1)

  • per-patient detection rate of adenoma of proximal colon

    the number of patients with at least one adenoma identified divided by total number of patients completing colonoscopy

    1 day

Study Arms (2)

Second Examination

EXPERIMENTAL

Eligible patients who consent to participate undergo planned colonoscopy by endoscopists performing procedures that day per normal standard of care. The colonoscope is passed to the cecum and then withdrawn to the hepatic flexure with washing and aspirating of colonic contents as needed to optimize visualization of colonic mucosa. Then, the colonoscope is inserted to the cecum and withdrawn to the hepatic flexure again for second examination.

Procedure: Second Examination

Traditional Examinaiton

NO INTERVENTION

Eligible patients who consent to participate undergo planned colonoscopy by endoscopists performing procedures that day per normal standard of care. The colonoscope is passed to the cecum and then withdrawn to the hepatic flexure with washing and aspirating of colonic contents as needed to optimize visualization of colonic mucosa. Then, the colonoscope is withdrawn to the anus directly.

Interventions

The colonoscopy is passed to the cecum and then withdrawn to hepatic flexure. Then, the scopy is inserted to the cecum and withdrawn to hepatic flexure again for second foreard view examination.

Second Examination
