Intervention(s)

Use water-slider method to retrieve resected polyps. 1. Resect the polyp using a snare. 2. Minimally draw the resected specimen toward the suction channel to avoid polyp loss. It is important not to fully push the suction button. 3. Using a water-jet channel, add enough water to a nearby site in the colon. 4. Push the suction button fully to suck the polyp in with the water.
Retrieve the resected specimen without adding water and without designating how to use the suction button (i.e., conventional suction retrieval).
