The hepatic flexure should be the hepatic flexure of the colon, which refers to the segment of the ascending colon and transverse colon that migrates close to the liver. Intramucosal carcinoma of the hepatic flexure of the colon means that the tumor is confined within the intestinal mucosa and belongs to carcinoma in situ, which is usually called early stage of cancer.
The wall structure of colon can be divided into mucosa, submucosa, muscularis propria and plasma membrane from inside to outside. Colon cancer usually originates from mucosa and gradually invades and infiltrates outward. Usually, the deeper the infiltration depth is, the more serious the condition is. Clinically, cancers confined to the mucosa and submucosa are called carcinoma in situ, that is, the early stage of cancer. Tumors in this stage rarely metastasize and thus have a good prognosis.
Colon cancer confined to mucosa or submucosa can usually be treated endoscopically, such as endoscopic mucosal resection, endoscopic dissection, etc. If postoperative pathology shows that the tumor has not invaded the basal layer of the mucosa, no further treatment is needed for subsequent treatment, and no surgical treatment is required.
Intramucosal cancer of the hepatic flexure of the colon belongs to the early stage of the tumor, and it seldom metastasizes after reasonable treatment, so patients do not need to worry too much, and regular follow-up can be enough. It is recommended that the patient should communicate with the supervising physician to determine the follow-up treatment and follow-up plan.
