No, you can’t.
There are a number of preparations that need to be made before a colonoscopy, such as an electrocardiogram (ECG) and related laboratory tests, and bowel preparation, which is the cleansing of the bowel.
Enteroscopy is a flexible tube with a miniature camera to enter the intestines for observation. Before the examination, it is necessary to complete the electrocardiogram, blood routine, blood biochemistry and other tests, in addition to a very important item is to complete the purging of the intestines, that is, to empty the intestinal tract through the means of dietary control and oral laxative, so as to be able to see the internal condition of the intestinal tract clearly.
To summarize, colonoscopy is not possible to go on the same day to improve the relevant preoperative preparation. Diet control should be started three days before, and bowel cleansing and fasting should be started the day before the colonoscopy is performed. It is recommended to make an appointment in advance and follow the doctor’s instructions to actively prepare.
