Experts pointed out that intestinal polyps is a general term for elevated lesions of the colon and rectum, and is a clinical diagnosis based on palpation, colonoscopic observation or barium enema X-ray examination. The clinical manifestations of intestinal polyps vary, and there may be no symptoms in the early stage, but the general clinical manifestations may include abdominal pain, diarrhea, blood in stool, mucus in stool, or with urgency.
What are the main symptoms of intestinal polyps?
Abnormal stool shape: normal stool should be cylindrical, but if the polyp is in the lumen of the colon and presses the stool, it will often be thinner or flattened, sometimes with blood traces attached.
Changes in stool habits: including changes in the timing and frequency of stools, as well as constipation or unexplained diarrhea. It is especially important to be alert when constipation and diarrhea occur repeatedly and alternately, or cause abdominal pain.
Blood in the stool: Patients with intestinal polyps are most likely to have blood in the stool, but many will mistake the bleeding stool for the symptoms of hemorrhoids, resulting in a delay in the best treatment. Experts say that the bleeding caused by hemorrhoids is often dripping blood after the stool, bright red, and in the usual way does not bleed. But bleeding caused by intestinal polyps is often mixed in the middle of the stool.
What is the likelihood of intestinal polyp lesions?
Multiple adenomas larger than 2.5 cm in diameter, or hard to the touch of fingers or instruments, or obvious congestion, or ulcers on the surface, should be considered the possibility of malignant transformation, and the possibility of malignant transformation should be different depending on the nature and size of the adenoma.
Familial polyposis, a rare hereditary polyposis. The colon and rectum are covered with polypoid adenomas, and malignancy is only sooner or later, and malignant changes are often not limited to one place, but are multicentric, in fact, some patients are already colorectal malignant when they seek medical attention.
Inflammatory polyps, hyperplastic polyps, except for inflammatory polyps may be malignant, it is difficult to determine or there is a possibility, hyperplastic polyps are clinically asymptomatic, mostly found occasionally during colonoscopy, due to its small body, mostly around 0.5cm, often does not cause discomfort.
The possibility of malignant transformation of papillary adenoma is quite high, and it is considered as pre-malignant lesion, and its malignant transformation rate is generally considered to be around 30%. The clinical manifestations of papilloma are mucus discharge or even large amount of mucus discharge or large amount of mucus diarrhea, which can be more than 3000ml per day, leading to severe dehydration, electrolyte disorders, circulatory failure, acidosis and other metabolic disorders. If supplemental treatment is not given in time and adenoma is not treated, it can cause life threatening.
