Colorectal polyps refer to the sum of all vegetations that protrude into the intestinal lumen, including neoplastic organisms and nonneoplastic vegetations, the former is a precancerous lesion and is closely related to carcinogenesis, and the latter is less related to carcinogenesis.

The disease may be caused by a combination of familial, hereditary, inflammatory, other environmental and dietary factors.
Clinical manifestations:
The clinical symptoms of colorectal polyps are often subtle, and even some gastrointestinal symptoms, such as bloating, diarrhea, and constipation, are overlooked because they are mild and atypical. Generally, it is often misdiagnosed as hemorrhoids and other ** diseases or "dysentery" and delays its necessary examinations. Patients with unexplained blood in the stool or gastrointestinal symptoms, especially middle-aged and elderly men over 40 years old, should be further examined.

Diagnosis:
Most polyps have an insidious onset and may be asymptomatic clinically. Some larger polyps can cause intestinal symptoms, mainly changes in stool habits, increased frequency, mucus or mucus blood in the stool, occasional abdominal pain, and a rare number of stools with a mass from the ** prolapse. Some patients may have long-standing hematochezia or anemia. Patients with a family history often have a hint about the diagnosis of polyps. Patients with polyposis should be routinely colonoscopic to rule out the syndrome.

Do intestinal polyps have to be removed?
It is necessary to see the pathological results, if the pathology is an adenoma, it must be cut, which is a precancerous lesion with a carcinogenic rate of 95%, if it is an inflammatory polyp or a polyp, it can be cut and rechecked regularly.

However, if inflammatory polyps continue to be stimulated by inflammation, they may continue to grow and develop into adenomatous polyps, and to a certain extent, they will also cause symptoms such as long-term blood in the stool, diarrhea, intussusception and even intestinal obstruction, which should also be removed.
So in clinical work,Endoscopic resection of all polyps is recommended except for tiny (5 mm) rectal polyps, or rectosigmoid polyps with high suspicion of hyperplastic polyps.
If the doctor judges that the endoscopic** can be cleanly removed, he will choose endoscopic minimally invasive excision, and the commonly used option is endoscopic mucosal dissection (ESD); If the doctor determines that the endoscopic minimally invasive surgery is not clean, then the patient needs surgery**.
Just because a polyp is removed doesn't mean you can rest easy. Due to the complexity of intestinal polyps, it is easy to make intestinal polyps, and there may be missed diagnosis during colonoscopy, so it is necessary to recheck the colonoscopy regularly, and the interval between reviews is determined according to the results of pathological examination, the integrity of resection, bowel preparation, health status, family history of bowel cancer and past medical history. Only regular follow-up colonoscopy can achieve true peace of mind.
