A 1.0cm*0.8cm intestinal polyp is a polyp of 1.0cm*0.8cm in size (planar dimension) found in the patient’s intestines. Intestinal polyp refers to a bulging lesion that protrudes from the mucosal surface into the intestinal lumen. Pathologically, they can be divided into adenomatous polyps, inflammatory polyps, misshapen polyps, and other types. Intestinal polyps can occur anywhere in the intestinal tract, with a predominance in the colon and rectum. Small intestinal polyps are rare and often asymptomatic, and may present with recurrent abdominal pain and intestinal bleeding. Colorectal polyps are most common in the sigmoid colon and rectum, and most are adenomatous polyps in adults. About half of adenomatous polyps larger than 2cm in diameter become cancerous, while the cancer rate of other types of polyps is much smaller. Polyps are often detected by colonoscopy, and usually 1.0cm*0.8cm intestinal polyps are directly removed by common surgery with pathologic examination. If cancer is found, further treatment such as radiotherapy and chemotherapy (e.g. 5-FU, mitomycin) is needed. Therefore, patients with 1.0cm*0.8cm intestinal polyps should go to regular hospitals for relevant examinations to clarify the pathology of the polyps and then do relevant treatment.
