The common clinical symptoms of gastric stone are upper abdominal pain, fullness, nausea, vomiting, anorexia, weight loss and upper gastrointestinal bleeding. Hawthorn gastric stone mostly develops within a few days to 2 weeks after eating hawthorn and mostly presents as acute upper abdominal pain and gastrointestinal bleeding. In addition to pressure pain in the gastric region, in some cases, a hard, smooth and movable mass can be palpated in the gastric region. The diagnosis of gastric stone is based on the medical history, clinical manifestations, combined with X-ray and gastroscopic findings.

Treatment of gastric stone In the past, most of the treatment of gastric persistent stone was done by herbal lithotripsy or surgical lithotripsy. Chinese herbal treatment takes a long time, and surgical lithotripsy is more painful for patients and has the potential for complications. With the development of fiberoptic endoscopic therapeutics and various therapeutic accessories, mechanical lithotripsy of large persimmon stones and transoral removal of small persimmon stones have been carried out under gastroscopy. Generally, experienced endoscopists have a 100% success rate in removing gastric stones up to 2 cm at a time or cutting them into fragments, while very few patients require surgical extraction. Once the stone is removed, the disease is cured, which not only prevents further growth of the stone, but also eliminates the economic expense of long-term medication and reduces the trouble and mental burden caused by repeated consultations.
