A snare polypectomy kit is a set of endoscopic tools used to remove polyps from the digestive tract. The main device is a wire loop, or snare, that is placed around a polyp and tightened to cut it away. Some snares remove tissue without cautery, while others use electrosurgical current. The removed tissue is usually sent to a laboratory for pathology review.
read more about snare polypectomy kit ...A snare polypectomy kit is used during endoscopy or colonoscopy when a clinician needs to remove a polyp. It is commonly used for colon polyps, but snares can also be used in other parts of the gastrointestinal tract depending on the procedure. Removing polyps can help diagnose abnormal tissue and may reduce the risk of some polyps becoming cancerous. The technique depends on polyp size, shape, location, and bleeding risk.
Kit contents vary, but the main component is an endoscopic snare passed through the working channel of an endoscope. Some kits include a snare catheter, handle, electrosurgical connector, retrieval supplies, specimen container, or related accessories. Cold snare devices are used without electrical current, while hot snares connect to an electrosurgical unit. The clinician chooses the device based on the polyp and procedure plan.
The endoscope is guided to the polyp, and the snare loop is opened around the target tissue. The loop is tightened at the base or around the polyp, then the tissue is cut with mechanical force or electrocautery. The polyp is retrieved when possible so it can be examined by pathology. The site is checked for bleeding, incomplete removal, or other concerns before the procedure continues.
Possible risks include bleeding, perforation, post-polypectomy pain, infection, incomplete removal, or delayed bleeding after the procedure. Larger polyps and hot snare techniques can carry higher risk than small cold snare removal. Patients should follow instructions about diet, medications, activity, and follow-up colonoscopy timing. Severe abdominal pain, fever, dizziness, black stools, or heavy rectal bleeding should be reported urgently.
It is an endoscopic procedure rather than open surgery. The polyp is removed through an endoscope using a snare device.
Cold snare polypectomy cuts tissue without electrical current. Hot snare polypectomy uses electrocautery to cut tissue and help control bleeding.
Yes. Removed polyps are commonly sent to pathology so the tissue can be checked under a microscope.
New polyps can develop over time, and some removed areas may need follow-up. The clinician recommends the next exam based on pathology and polyp history.
