Summary

Small colon polyps which are found during colonoscopy insertion are sometimes difficult to find during withdrawal and thus missed. The investigators aim to evaluate the differences of colon polyp/adenoma detection rates of patients undergoing additional inspection and polypectomy during insertion as compared to the patients undergoing traditional practice of careful inspection and polypectomy performed entirely during withdrawal of colonoscopy.

Conditions

  • Colon Polyp
  • Colon Adenoma

Interventions

PROCEDURE

Colon polypectomy

For participants assigned into the experimental group, colon lumen is washed and the debris is suctioned as the colonoscopy is slowly inserted from rectum to cecum. Deliberate and systematic inspection of the mucosa is performed with adequate insufflation during both the insertion and withdrawal phases. Colon polyps with size \<10 mm are removed as they are identified on insertion and withdrawal. Polyps with size \>10 mm are removed only during withdrawal. For participants assigned into the control group, deliberate inspection and polyp removal are performed exclusively on colonoscopy withdrawal.During insertion, minimal mucosal inspection and insufflation are applied to efficiently advance the instrument into cecum.
