Duodenal adenomas are benign polypoid lesions with an adenomatous epithelial composition that occur in the duodenum.
Adenomas are more common, also known as adenomatous polyps, and are heterogeneous hyperplasia or intraepithelial neoplasia of the gastric mucosa. They may originate in the duodenum, but can also be found in the gastric sinus, gallbladder, pancreatic duct, bile duct and esophagus. Adenomas that occur in the duodenum are called duodenal adenomas.
Duodenal adenomas can be either benign adenomas, benign polyps or malignant tumors. Once a malignant tumor of the duodenum is diagnosed, surgical treatment is often required, and postoperative pathology further clarifies whether the tumor is malignant or cancerous. If it is a lipoma, liposarcoma, lymphoma, etc., a decision is made as to whether or not further chemotherapy or radiation therapy is needed.
The incidence of duodenal adenoma is not high, once the above situation occurs, the diagnosis should be clarified as soon as possible and treatment should be carried out, the treatment method is mostly endoscopic resection, if the lesion is extensive, it is necessary to choose open surgical resection and nearby lymph node dissection, and further chemotherapy and other treatments after the operation.
After surgery and other treatments for duodenal adenoma, regular review is needed.
