Endoscopic excision is usually the preferred method, and trap electrocautery is also feasible, which is relatively less damaging, less reactive, and more effective. Tubular adenoma is the most common type of colorectal adenoma, which is an abnormal proliferation of glands, mostly round or oval, smooth or lobulated, pink or dark red in color, and soft in texture. As the tumor increases in size, the texture can become solid and can have a tip or a broad-based non-tip, and the size of the tumor can reach several millimeters or even centimeters. The clinical features are more common in elderly people over 60 years old, no gender difference, slow growth of tumor, no pain and other conscious symptoms, small size, mostly within 2cm in diameter.
