Diverticulum of digestive tract refers to a bag protrusion formed by local outward bulging of gastrointestinal wall. It can occur in any part of the gastrointestinal tract, with the descending duodenum as the most common, followed by the esophagus and small intestine. Diverticulum of digestive tract is mostly asymptomatic, often found by chance in X-ray barium meal, barium enema or fiberoptic endoscopy. If the diverticulum is large or complicated with diverticulitis, local discomfort or dull pain may occur, sometimes bleeding. When Meckel's diverticulum contains heterotopic tissue of gastric mucosa, peptic ulcer may occur. Treatment support therapy includes blood transfusion. In patients with persistent bleeding, pituitrin was dripped through arterial catheter during mesenteric arteriography, and 50% of patients could effectively stop bleeding. Invalid patients may consider surgical treatment. What is your age, underlying disease, diverticulum location, size and amount of bleeding? Did you defecate? Whether defecation is black, whether it is formed large, how much stool. In this case, if your physical condition permits surgery, it is the best, if the body does not permit, you can only maintain treatment. Usually keep the anus clean and hygienic, eat more coarse grains, keep the stool unobstructed.
