What does the term "Polypectomy" refer to in endoscopy?

The term "Polypectomy" specifically refers to the surgical removal of polyps from the gastrointestinal tract. Polyps are abnormal tissue growths that can occur in various parts of the GI system, including the colon and stomach. Polypectomy is often performed during endoscopic procedures, such as colonoscopy, where the endoscope allows the physician to visualize the polyps and remove them safely.

This procedure is important because polyps can sometimes develop into cancer; thus, their removal is a preventative measure. The ability of the endoscopist to remove these growths using techniques such as snare polypectomy enhances patient outcomes by reducing cancer risk and facilitating early intervention.

Other terms in the choices refer to different procedures; for instance, biopsy pertains to taking tissue samples rather than removal, while dilation focuses on opening strictures rather than removing polyps.
