- For symptomatic polyps, they have to be removed.
- Polyps are removed to prevent them from advancing to cancers later on in life.
How is the procedure done
In advanced polyps, an endoscope containing a loose noose is inserted into the lumen of the
colon. Upon finding a polyp, the noose of an endoscope is used to strangulate the base of the
polyps until it cuts off. It is the electric current which is passed on the noose (diathermy)
which cuts it off and ensures that no bleeding occurs thereafter. The cut polyp is then sucked
into the endoscope out for pathological investigations.
The greatest risk is that of bleeding following removal of the polyps in polypectomy.
