There is no clear relationship between intestinal diverticula and intestinal cancer. 1. Diverticulum is a localized cystic expansion of the digestive tract, there are two kinds of diverticula: true (whole layer expansion) and false (only mucosa and submucosa expansion), the vast majority of diverticula are expanded outside the lumen of the digestive tract, and a very small number of diverticula are expanded inside the lumen, which is called diverticula in the lumen. Multiple diverticula at the same time called diverticulosis (diverticulosis), this disease is most common in the colon, duodenum, followed by stomach diverticula least common. 2. Asymptomatic diverticula do not need to be treated. When symptomatic diverticula coexist with other abdominal disorders, the latter should be treated first. If the symptoms are caused by diverticula, comprehensive internal medicine treatment should be adopted, including dietary regulation, acid-suppressing and antispasmodic, anti-inflammatory and gastrointestinal decompression, etc. Unless there is cancer, which is difficult to control, the diverticula should be treated first. Surgery is usually not considered unless there are cancerous, uncontrollable complications (bleeding, obstruction, inflammation or perforation). It is recommended that patients who are not feeling well should go to the hospital in time to improve the examination, so as not to delay the condition.
