Colonic polypectomy

Colonic Polypectomy is a medical procedure performed to remove polyps from the large intestine, also known as the colon. Polyps are abnormal growths that can develop in the lining of the colon, and while most are benign, some can develop into colorectal cancer.

Procedure

The procedure is typically performed during a colonoscopy, a diagnostic procedure that allows a gastroenterologist to examine the entire length of the colon. The polyps are removed using a wire loop that is passed through the colonoscope. This loop is used to either cut the polyp from the colon wall using an electric current or to remove it using a snare technique.

Types of Colonic Polypectomy

There are several types of colonic polypectomy procedures, including:

• Snare Polypectomy: This is the most common type of polypectomy. A wire loop is passed through the colonoscope to cut the polyp from the colon wall using an electric current.

• Cold Snare Polypectomy: This procedure is similar to a snare polypectomy, but it does not use an electric current. It is often used for smaller polyps.

• Endoscopic Mucosal Resection (EMR): This procedure is used for larger polyps. It involves injecting a solution under the polyp to lift it away from the underlying tissue and then removing it with a snare.

Risks and Complications

While colonic polypectomy is generally safe, it does carry some risks, including bleeding, perforation of the colon, and incomplete removal of the polyp. In rare cases, a condition known as post-polypectomy syndrome can occur, which is characterized by pain and fever following the procedure.

Aftercare

Following a colonic polypectomy, patients are typically monitored for a short period of time to ensure there are no immediate complications. They may experience some discomfort or bloating, but these symptoms usually resolve within a few hours.
