Gastric mucosal prolapse

Gastric mucosal prolapse is caused by abnormally loose gastric antral mucosa that protrudes retrogradely into the esophagus or prolapses through the pyloric duct into the duodenal bulb. Mild patients may be asymptomatic or have nonspecific symptoms such as bloating and belching. Part of the gastric mucosa prolapsed into the pylorus and could not be immediately reset, may have mid-upper abdominal pain, burning pain and even colic, and may radiate to the back, often accompanied by nausea and vomiting. The occurrence of this disease is mainly related to inflammation of the stomach and duodenum, which can also occur with gastric mucosal infiltration of malignant cells.
