A painless gastroscopy does not necessarily need to be done in conjunction with a colonoscopy.
Painless gastroscopy can observe the stomach, esophagus, duodenal bulb and other parts of the stomach, esophagus and duodenal bulb through the hose with a camera at the head of the gastroscope, and finally can achieve the diagnosis and treatment of upper gastrointestinal system diseases, and for some patients can also be excised from the esophagus, stomach, duodenal and other parts of the esophagus, stomach, and duodenum under the painless gastroscope, such as tumors, polyps and other lesions.
Enteroscopy is the most direct and effective way to observe intestinal lesions, which can observe intestinal lesions in multiple directions and angles in the intestines as well as treat the lesions that appear in the intestines.
Therefore, for patients without intestinal lesions, only gastroscopy can be performed without colonoscopy, but for patients with gastrointestinal lesions, gastroscopy and colonoscopy need to be performed at the same time.
If you are not sure whether you need to undergo painless gastroscopy and colonoscopy, you can go to the hospital and ask the doctor to make a judgment.
