Colonoscopy not only visualizes anal canal swellings, but also other lesions of the intestines as well as performing colonoscopic treatment.
Colonoscopy can observe diseases of the anal canal, rectum, sigmoid colon, descending colon, transverse colon, and ascending colon, and is used to examine and diagnose diseases such as ulcerative colitis, tuberculous bowel disease, inflammatory bowel disease, intestinal polyps, and intestinal tumors.
When doing colonoscopy, not only can we find the anal canal swelling, but also can find whether the anal canal intestinal wall is thickened and stiff, erosion, ulceration, etc. We can see the tumor as well as remove a little tumor tissue under the colonoscopy and do the pathological section examination, which is able to clarify the nature of the lesion, and at the same time, we can also treat some of the intestinal lesions.
In the clinic, enteroscopy is a better way to check anal canal swelling. Patients are advised to follow the doctor’s advice for specific examinations according to their personal situation.
