Gastric perforation is a condition in which a persistently worsening gastrointestinal ulcer lesion erodes the stomach wall, causing it to perforate and allowing the stomach contents to enter the abdominal cavity. Most patients with gastric perforation have some gastrointestinal lesion, such as a gastrointestinal ulcer. Patients with poor daily care, overeating, heavy drinking; or taking certain medications, such as aspirin, may aggravate the ulcer and cause gastric perforation. Gastric perforation usually has an acute onset, causing severe abdominal pain, nausea and vomiting, cold sweats, and cold extremities, and in severe cases, it may cause the patient to go into shock, or even endanger his or her life. Therefore, patients with gastric ulcer lesions should be treated reasonably under the guidance of a doctor, and after the symptoms of gastric perforation appear, they should also seek urgent medical treatment to avoid serious complications.
