Gastroenteroscopy can be used to diagnose and treat gastrointestinal disorders. Gastroenteroscopy is generally recommended for people who fulfill the indications for gastroenteroscopy.
1. People who meet the indications for gastroscopy: people with unexplained upper gastrointestinal symptoms such as dysphagia, retrosternal pain, epigastric pain, discomfort, fullness, loss of appetite, etc.; people with unexplained upper gastrointestinal bleeding; people with upper gastrointestinal pathology that cannot be confirmed or explained by barium x-ray, especially mucous membrane pathology and suspected tumors;
Lesions requiring follow-up observation, such as peptic ulcer, atrophic gastritis, gastric surgery, reflux esophagitis, Barrett’s esophagus, etc.; comparative observation before and after medication or follow-up after surgery; endoscopic treatment, such as sclerosing agent injection and ligation of esophagogastric fundal varicose veins, dilatation of esophageal strictures and stent placement, and resection of upper gastrointestinal polyps.
2. Indications for colonoscopy: if there is blood in stool, abnormal defecation, abdominal discomfort and other lower gastrointestinal symptoms but the diagnosis is not clear; barium enema suspects that there are intestinal lesions and further diagnosis is needed; abdominal mass, especially lower abdominal mass, needs to be clearly diagnosed; and low-level intestinal obstruction of unknown cause;
Regular follow-up after colorectal cancer surgery and colorectal polypectomy; census of colorectal tumors; unexplained wasting and anemia; colonic polyps; intestinal torsion, intussusception repositioning and so on.
It is recommended to seek medical attention when gastrointestinal discomfort occurs. In addition, gastroscopy screening is recommended routinely for those over 40 years of age, and colonoscopy screening is recommended for those older than 45 years of age.
