chronic peptic ulcer

Peptic ulcer mainly refers to chronic ulcers occurring in the stomach and duodenum, and is a common and frequently occurring disease. Various factors contribute to ulcer formation, among which the digestive effect of acidic gastric juice on the mucosa is the basic factor, hence the name. Any site contacted by acidic gastric juice, such as the lower esophagus, anastomotic site after gastrointestinal anastomosis, jejunum, and Meckel's diverticulum with ectopic gastric mucosa, can be affected. The vast majority of ulcers occur in the duodenum and stomach, hence they are also called gastric and duodenal ulcers. Chronic gastritis and peptic ulcer are common diseases of the digestive system, with a tendency to recur. They are generally treated with medical drug therapy, with symptom improvement or cure, but most patients experience multiple recurrences.
