What are the alternatives to gastroscopy and colonoscopy for gastrointestinal examinations?

In addition to gastroenterology endoscopy, there are several other methods for examining the gastrointestinal tract. Gastrointestinal barium meal is a diagnostic procedure using X-rays to observe the structure and function of organs such as the esophagus, stomach, and duodenum. Abdominal color ultrasound uses ultrasound waves to visualize the wall of the gastrointestinal tract and surrounding tissues, making it suitable for preliminary screening of gastrointestinal diseases. In addition, Helicobacter pylori testing can detect the presence of H. pylori infection in the stomach through various methods, helping to identify the cause of gastric discomfort. Other commonly used gastrointestinal diagnostic techniques include barium enema, stool examination, and gastrointestinal tissue biopsy. Each of these methods has its own characteristics, and selection should be based on the specific medical condition and physician recommendations.
