Colon polyp: It is a protruding and bulging lesion in the colon due to inflammatory stimulation, heredity and other factors. They can appear in the hepatic flexure area, causing elevated lesions in the hepatic flexure. 2. Colonic cysts: due to the appearance of cysts under the mucosa or plasma membrane of the colon, which can be manifested in the hepatic flexure area, resulting in the bulging of the hepatic flexure. 3. Tubular adenoma of the colon: it is a bulging lesion on the mucosal surface of the colon protruding into the intestinal lumen, and when it occurs in the area of hepatic flexure, it will cause bulging lesions of the hepatic flexure. 4. Colorectal cancer: it is a malignant tumor that appears in the colon, and when the tumor appears in the hepatic flexure of the colon, it will lead to bulging lesions in the hepatic flexure. If you find elevated lesions in hepatic flexure, you should go to the hospital for relevant examination in time, so as to clarify the specific cause of the disease and carry out treatment as soon as possible.
