colorectal polyps
Introduction
Introduction to colorectal polyps CokicPolyp is a general term for all neoplasms that protrude into the intestine, including both neoplastic and non-neoplastic. The former is closely related to carcinogenesis and is a precancerous lesion. The latter has less relationship with cancer. Because these two polyps are not easy to distinguish in clinical practice, Changtong uses polyps as a preliminary diagnosis, and further classification after pathological examination is confirmed. Therefore, the so-called colorectal polyps in clinical practice do not indicate the pathological nature of polyps, usually clinicians. The polyps are mostly non-neoplastic polyps, and the tumor polyps are collectively called adenomas. basic knowledge The proportion of illness: the probability of illness over 50 years old is 0.06% Susceptible people: no specific people Mode of infection: non-infectious Complications: blood in the stool
Cause
Colorectal polyps
Cause (75%):
The disease may be caused by family genetic or inflammatory hyperplasia, plus other environmental and dietary factors. The specific cause is not clear.
Prevention
Colorectal polyps prevention
There are no effective preventive measures for this disease, which can minimize the stimulation of environmental and dietary factors.
Complication
Colorectal polyps complications Complications, blood in the stool
Some patients may have long-term blood in the stool or anemia.
Symptom
Colorectal polyps symptoms Common symptoms Defecation frequency abnormal diarrhea Abdominal pain Skin mucous membrane pigmentation Polypemia Blood in the large intestine Black bloating Fecal habit habits change Constipation
The clinical symptoms of colorectal polyps are often not obvious. Even some gastrointestinal symptoms such as bloating, diarrhea, constipation, etc. are neglected because of mildness and atypicality. Generally, blood, stool, blood, mucus and blood come to the clinic, often misdiagnosed as an anal disease or dysentery such as hemorrhoids and delay the necessary examination.
Examine
Colorectal polyps
1. X-ray barium enema can detect colorectal polyps sensitively through the filling defect of tincture, but the lesions are often not correctly classified and characterized.
2. Polyps found by endoscopy must be biopsied to understand the nature and type of polyps and whether or not they are cancerous. Small or pedicled polyps can be removed by biopsy forceps or snares, and large or broad-based polyps can only be clamped for biopsy. It is the most important means of detecting and confirming large intestine polyps.
3, due to the same adenoma, the amount of villus and the degree of atypical hyperplasia in different parts are often different, so the lesions taken at the biopsy can not fully represent the whole picture. There is no cancer in the biopsy. It is not certain that the adenoma is cancerous elsewhere. Therefore, the degree of atypical hyperplasia and non-cancerous changes of adenoma often require the removal of the entire tumor, which can be confirmed after careful biopsy. The results of biopsy pathology can be used for reference, but not the final conclusion.
Diagnosis
Diagnosis and identification of colorectal polyps
diagnosis:
Because colorectal polyps are often asymptomatic in clinical practice, even some gastrointestinal symptoms such as bloating, diarrhea, constipation, etc. are also mild and atypical, and are often overlooked. Generally, blood is used, blood is in the stool, and mucus blood comes to the doctor. Often misdiagnosed as anal disorders such as hemorrhoids or dysentery and delays the necessary examinations. Therefore, the diagnosis of colorectal polyps must first improve the doctor's understanding of the disease, for those who have unexplained blood in the stool or gastrointestinal symptoms, especially in the middle of 40 years old. Older men should pay attention to further examination and diagnosis, so the discovery rate and diagnosis rate of colorectal polyps are expected to be greatly improved.
Differential diagnosis:
It is differentiated from adenomatous polyps, papillary adenomas, melasma polyps, and inflammatory polyps.
