How can you minimize contact between healthy tissues and a polyp when cauterizing with a snare?

To minimize contact between healthy tissues and a polyp when cauterizing with a snare, positioning the polyp for broad contact is effective as it allows for better treatment while protecting adjacent healthy tissues. When the polyp is adequately positioned and the snare is placed around it, it can be resected more precisely. This helps to ensure that the cauterization is directed primarily at the polyp itself and minimizes the chances of thermal injury to surrounding healthy tissues.

By establishing broad contact, the cautery effect is contained to the targeted area, reducing the risk of complications such as perforation or unintended damage to healthy structures. Additionally, the use of a correctly sized snare, preparation of the site, and technique all contribute, but the primary focus should remain on how the positioning of tissues influences the cautery process and protects normal anatomy.
