Gastrointestinal function tests include routine fecal examination, gastroscopy, colonoscopy, Helicobacter pylori test and other tests.
1. Stool routine: This test can observe whether there is pus, blood, worm eggs, etc. in the stool, thus assisting in determining whether there are lesions in the gastrointestinal tract.
2. Gastroscopy: through gastroscopy, lesions in the esophagus, stomach and duodenum can be seen. Under the observation of gastroscopy, hemostatic treatment can be carried out, and endoscopic mucosal resection or stripping surgery can be carried out for benign tumors found.
3. Colonoscopy: colonoscopy can visualize the colorectal lesions from the anus to the ileocecal valve, and for the relatively small polyps can be treated with lancing and electrocoagulation.
4. Helicobacter pylori test: C13, C14 breath test and blood test for Helicobacter pylori, etc. This test is very helpful for the diagnosis of peptic ulcer, gastric cancer and other diseases.
