Gastric perforation and gastric bleeding, with gastric perforation being more serious. Gastric perforation is a disruption of the integrity of the gastric mucosa due to various etiologies, leading to changes in the permeability of the gastric mucosa to the mucosal layer to the plasma layer, and finally to perforation. Gastric perforation can cause gastric contents to enter the peritoneal cavity, leading to acute diffuse peritonitis, which can cause infectious shock in severe cases and is an acute abdominal disease that requires immediate surgical treatment, otherwise it can be life-threatening at any time. Gastric bleeding is a variety of causes of bleeding in the stomach, the most common clinically include acute gastric mucosal lesions, gastric ulcers and ruptured esophagogastric fundic varices bleeding, the prognosis is better with active treatment, but there can also be acute bleeding leading to hemorrhagic shock, life-threatening, but relatively speaking, gastric perforation is more serious than gastric bleeding disease.
