Colonic polypectomy is the removal of colorectal polyps in order to prevent them from turning cancerous. Method of removing a polyp with a snare Gastrointestinal polyps can be removed endoscopically through colonoscopy or esophagogastroduodenoscopy , or surgically if the polyp is too large to be removed endoscopically.
A colorectal polyp is a polyp (fleshy growth) occurring on the lining of the colon or rectum. [1] Untreated colorectal polyps can develop into colorectal cancer. [2] Colorectal polyps are often classified by their behaviour (i.e. benign vs. malignant) or cause (e.g. as a consequence of inflammatory bowel disease).
Although colon cancer is usually not found in polyps smaller than 2.5 cm, all polyps found are removed since their removal reduces the likelihood of future colon cancer. When adenomatous polyps are removed, a repeat colonoscopy is usually performed three to five years later. [citation needed] Most colon polyps can be categorized as sporadic.
Treatment consists of intravenous fluids, antibiotics, and avoiding oral intake of food, water, etc. until symptoms improve. Risk factors include right colon polypectomy, large polyp size (>2 cm), non-polypoid lesions (laterally spreading lesions), and hypertension. [47] Although rare, infections of the colon are a potential colonoscopy risk.
Traditional serrated adenoma seen under microscopy with H&E stain, showing serrated crypts. SPS may occur with one of two phenotypes: distal or proximal. [6] The distal phenotype may demonstrate numerous small polyps in the distal colon and rectum, whereas the proximal phenotype may be characterized by relatively fewer, but larger polyps in the proximal colon (cecum, ascending colon, etc.). [6]
1-5 days after polypectomy: Causes: Polypectomy during colonoscopy: Risk factors: Hypertension, right colon polypectomy, large polyp size (>2 cm), non-polypoid lesions (laterally spreading lesions) [1] Differential diagnosis: Perforation: Prevention: Antibiotic prophylaxis [2] Treatment: IV fluids, antibiotics, nothing by mouth: Prognosis ...
The serrated polyposis syndrome (SPS) is a relatively rare condition characterized by multiple and/or large serrated polyps of the colon. Serrated polyps include SSLs, hyperplastic polyps, and traditional serrated adenomas. Diagnosis of this disease is made by the fulfillment of any of the World Health Organization's (WHO) clinical criteria. [4]
In medicine, a polypectomy is the surgical removal of an abnormal growth of tissue called a polyp. Polypectomy can be performed by excision if the polyp is external (on the skin). [ 1 ] [ additional citation(s) needed ]
