Endoscopic Polypectomy

A polyp refers to a protuberance into the lumen above the surrounding colonic mucosa, and the Paris classification of superficial neoplastic lesions of the gastrointestinal tract can be used to classify adenomas into polypoid and nonpolypoid lesions.

Endoscopic polypectomy is sufficient treatment for leiomyomas, which are uniformly clinically benign. From: Surgical Pathology of the GI Tract, Liver, Biliary Tract, and Pancreas.

How is polypectomy done?

If your doctor discovers polyps during your colonoscopy, they'll usually perform apolypectomy at the same time. ... Larger polyps (up to 2 centimeters in diameter) can be removed using a snare. In snare polypectomy, your doctor will loop a thin wire around the bottom of the polyp and use heat to cut the growth off.

Polypectomy is a fundamental skill utilized by all endoscopists who perform colonoscopy. Mastery of polypectomy is difficult and requires both significant experience and study. It is clear that polypectomy is efficacious in reducing the risk of colon cancer development by interrupting the adenoma to carcinoma progression. ecision making about how to perform polypectomy is often made during colonoscopy when a polyp is detected. A general rule is that all potential adenomas should be removed. The endoscopic appearance of a polyp is often not necessarily a good indicator of its histologic nature.

The method chosen for polypectomy is often related to the appearance and size of the polyp. Polyps are usually described as being pedunculated, sessile or flat.

Cold forceps polypectomy:

Cold forceps polypectomy was the technique of choice for small polyps, particularly polyps 1 to 3 mm in size.  Cold forceps can easily grasp small polyps that otherwise might be too small to snare.

Hot forceps polypectomy:

Hot forceps polypectomy is another option for small polyps. Hot forceps polypectomy is similar to cold forceps except it uses electrocautery to try to destroy residual polyp tissue intentionally left behind.  In hot forceps polypectomy, only the tip of the polyp is grabbed in the forceps. The small polyp is pulled into the colon lumen to create a tent-like effect and electrocautery is applied to destroy the polyp base while preserving the polyp tissue inside the forceps as a histological specimen.

Snare polypectomy:

It is the preferred method for removal of polyps 1 cm or greater in size. A snare is a self-contained metal ring that is opened over the polyp and then closed entrapping polyp tissue for resection by closing the ring. Before pulling the snare out of the scope, the polyp should be brought to the six o’clock position. The polyp is pulled away from its base into the lumen tenting the colon wall to avoid burning the adjacent deep colon layers.

Large polyps:

In the past, large polyps often required surgery for removal, but now many can be managed endoscopically. Endoscopic Mucosal Resection (EMR) can be performed on sessile polyps 2 cm in size or larger. colonoscopic polypectomy is a continuously evolving therapy that has been remarkable at reducing the risk of colorectal cancer. Gastroenterologists must be thoughtful and proficient in techniques such as snaring, injection, tattooing, and all other tools related to polypectomy for endoscopic success.
