You need to take off your pants for a colonoscopy because the colonoscope, which is used for the examination, needs to be accessed through the anus to look at the intestines.
The examination is performed with the patient lying on the left side with both knees bent. The doctor inserts the scope through the anus into the patient’s large intestine and fills the intestine with air to dilate the intestine so that the structures in the intestinal lumen can be clearly seen on the monitor. During the examination, you need to cooperate with the doctor to change the position, from the left side of the lying position to the flat position or the right side of the lying position, may also need the doctor to press the patient’s abdomen, should be relaxed according to the doctor’s request to cooperate.
Enteroscopy can choose between painless enteroscopy and ordinary enteroscopy, and most patients can afford ordinary enteroscopy. For patients who are particularly nervous, it is easy to cause spasm of the intestines, which intensifies the discomfort and pain, and they even cannot cooperate to complete the examination, at this time, they can apply for painless colonoscopy, that is, the examination is carried out under anesthesia.
It is true that you need to take off your pants for the colonoscopy, but the colonoscopy is all done in a very private room where the patient’s privacy is very important, and no other patients will be present during the examination.
