Chronic recurrent abdominal symptoms and chronic recurrent gastric disease are usually benign. There is no need to repeatedly check the gastroscopy because the symptoms are not treated well, which results in excessive worry and worsening of symptoms. So what are the conditions in which the doctor will recommend a repeat gastroscopy? In the following cases, the doctor will recommend a repeat gastroscopy because he or she is concerned about the chance of a malignant condition Gastric ulcers over 2cm, gastroscopy after 2 months of treatment Esophageal ulcers after 3 months of treatment Gastroscopy must be repeated within a shorter period of time for very large ulcers with high suspicion of cancerous ulcers on the first gastroscopy, and repeated biopsies must be taken. Gastroscopy for atrophic gastritis with mild heterogeneous hyperplasia is repeated in 6 months to 1 year Gastroscopy for atrophic gastritis with moderate to severe heterogeneous hyperplasia is repeated in 3-6 months Gastroscopy for gastric or duodenal polyps over 1 cm is generally recommended for gastroscopic removal and gastroscopy is repeated in 1 year. Duodenal ulcers or very small polyp-like bulges are hardly cancerous and therefore do not require repeat gastroscopy. For people with superficial gastritis, bile reflux gastritis, erosive gastritis, hemorrhagic gastritis, and augmented erosive gastritis, routine gastroscopy review is not required in the absence of other alarming symptoms. For those who need to review HP, a 13C breath test (referred to as a blow test) is really all that is needed.
