Anterior pyloric ulcer

A chronic ulcer located between the cardia and the pylorus is called a gastric ulcer (GU) and is a type of peptic ulcer. Peptic ulcer can occur in the stomach, duodenum, or the lower esophagus, near the anastomosis of the stomach and jejunum, and on ectopic gastric mucosa in the Meckel diverticulum. The formation of these ulcers is related to the digestion of gastric acid and pepsin, so it is called peptic ulcer. The vast majority of this disease is located in the stomach and duodenum (98% to 99%). About 10% of the population may suffer from this disease in their lifetime, so it is a frequently-occurring and common disease and occupies an important position in digestive surgery.
