Gastric ulcers are usually completely cured by conservative medical treatment and do not require surgical treatment. At present, surgical treatment of gastric ulcer is mainly limited to a small number of people with serious complications, including: 1. gastric ulcer with massive bleeding, if medical treatment is ineffective, surgical hemostasis is required. 2. gastric ulcer with acute perforation that cannot be repaired microscopically, surgical repair of the perforation is also required. 3. gastric ulcer with scarring pyloric obstruction requires surgical treatment to remove the obstruction. 4. gastric ulcer with suspected cancerous changes requires prophylactic surgical resection to avoid gastric cancer. 5. Surgery is also recommended for a small number of intractable gastric ulcers for which medical treatment has failed. Therefore, it is recommended that patients who clearly have gastric ulcer should be given active anti-ulcer treatment under the guidance of a gastroenterologist as soon as possible to avoid serious complications.
