acute perforation of peptic ulcer

Acute perforation is a serious complication of gastroduodenal ulcers and a common surgical acute abdomen. It has a sudden onset, severe condition, and rapid changes, requiring emergency management; improper diagnosis and treatment can be life-threatening. Duodenal ulcer perforation is more common in male patients, while gastric ulcer perforation is more often seen in elderly women. The vast majority of duodenal ulcer perforations occur on the anterior wall of the bulb, and 60% of gastric ulcer perforations occur on the lesser curvature of the stomach. In China, the incidence is higher in the south than in the north, and higher in urban areas than in rural areas. This may be related to factors such as diet and working environment. The transition periods between autumn and winter and between winter and spring are high-incidence seasons.
