The typical clinical manifestations are abdominal pain, abdominal masses and jam-like stools, which are usually treated with air enemas. The majority of adult intussusceptions occur due to tumors in the intestinal tract, including lymphoma, mesenchymal tumors or malignant tumors such as intestinal cancer, and the symptoms are mainly abdominal pain or complete or even incomplete intestinal obstruction. In adults, once intussusception occurs, it is usually cured by radical resection of intestinal cancer or local bowel resection due to tumor.
