polyp

Examples of polyp in the following topics:

• Polyps in the Colon

  • If an adenomatous polyp is found with sigmoidoscopy or if a polyp is found with any other diagnostic modality, the patient must undergo colonoscopy for removal of the polyp(s).
  • Even though colon cancer is usually not found in polyps smaller than 2.5 cm, all polyps found are removed since the removal of polyps reduces the future likelihood of developing colon cancer.
  • Adenomatous polyps, or adenomas, are polyps that grow on the lining of the colon and which carry a high risk of cancer.
  • The other types of polyps that can occur in the colon are the hyperplastic and inflammatory polyps.
  • Polyps that are pedunculated (with a stalk) are usually less dangerous than sessile polyps (flat polyps).

• Sinusitis

  • Chronic sinusitis cases are subdivided into cases with polyps and cases without polyps.
  • When polyps are present, the condition is called chronic hyperplastic sinusitis.

• Colorectal Cancer

  • More than 80% colorectal cancers arise from adenomatous polyps making this cancer amenable to screening .
  • The interior surface of the colon shows an invasive colorectal carcinoma and two adenomatous polyps.

• Occult Blood

  • The common causes are cancer (colorectal cancer, gastric cancer, 2-10%), adenoma or polyps (20-30%), bleeding peptic ulcer, angiodysplasia of the colon, and sickle cell anemia.
  • In the event of a positive fecal occult blood test, the next step in the workup is a form of visualization of the gastrointestinal tract by one of several means: sigmoidoscopy, an examination of the rectum and lower colon with a lighted instrument to look for abnormalities, such as polyps; colonoscopy, a more thorough examination of the rectum and entire colon; virtual colonoscopy; endoscopy refers to upper gastrointestinal endoscopy sometimes performed with chromoendoscopy; and double contrast barium enema: a series of X-rays of the colon and rectum.

• Diverticular Disease

  • First time bleeding from the rectum, especially in individuals aged over age 40, could be due to colon cancer, colonic polyps, and inflammatory bowel disease rather than diverticulosis and requires clinical investigation.

• Anemia

  • In older men and women, the chances are higher that bleeding from the gastrointestinal tract could be due to colon polyp or colorectal cancer.

• Pharynx

  • Polyps or mucus can obstruct the nasopharynx, as can congestion due to an upper respiratory infection.
