Polypectomy: ideal for colon polyps treatment (P3)

There are different types of polypectomy treatment for polyps in the colon.

Dr. Rafael Barreto Zúñiga

Other techniques that gastroenterology and endoscopy also use for the prevention of colorectal cancer or colon cancer and rectal cancer, as well as the diagnosis of polyps in the colon are:

Advanced polypectomy : In addition to large sessile polyps, laterally extended lesions also include polyps difficult to access and those requiring special maneuvers to be resected. An advanced polyp is defined as one that is in a range> 2 to 3 centimeters in diameter. Pedicled polyps occasionally require advanced techniques of polypectomy especially when the head is very large, making it difficult to see and position the handle to the base.

Endoscopic Resection of the Mucosa in the Colon. - It is useful in the resection of large sessile polyps (> 2 cm) and superficial neoplasms of the colon and rectum. Evaluating the macroscopic aspects of the polyp as the presence of granularity and vascular pattern are indicators of REM. This technique involves injecting the submucosa with a solution (saline, glycerol), which expands the submucosal layer by elevating the polyp, presenting a mucosal mattress and an extended resection plane (with a polypectomy loop).

Recommendations before and after a polypectomy

It is important to mention that before undergoing a polypectomy it is required that the patient undergoes a preparation for colonoscopy with polyethylene glycol, this allows an adequate cleaning and facilitates the evaluation of the polyp and polypectomy. Suspend anticoagulation (at least 3 days before) assessing risk benefit of the procedure and the reasons why it is anti-aggregate or anticoagulated. After the polypectomy procedure, anticoagulation should not be instituted immediately, at least 48 hours have to be spent, or a cardiologist should be contacted to set up restarting guidelines.

After the polypectomy, generally at 3 months, the patient requires revision in case of large polyps or incomplete polypectomy, to decide according to histopathological diagnosis the follow-up parameters.
