Polypectomy is a minimally invasive procedure in which abnormal growths of tissue, called Polyp removed endoscopically without any incision on body. In addition to being part of a therapeutic procedure, a polypectomy is also used as a means to assess whether a growth is cancerous, precancerous, or non-cancerous.
Two different types of polypectomies:
- Snare polypectomy is a technique in which the doctor loops a thin wire (snare) around the base of the polyp and uses heat to simultaneously cut off the growth and cauterize (stop bleeding) the wound.
- Piece-meal polypectomy is used to remove large growths that would otherwise be removed by surgery. If a person is unable to undergo bowel surgery, this technique removes the growth piece by piece during the course of a endoscopic procedure. It’s rare and reserved only for the biggest polyps, as most polyps are very tiny and can be removed quickly with a variety of techniques.
