Ordinary colonoscopy takes about 15 minutes to do, but the exact time varies from person to person.
Ordinary colonoscopy takes about 15 minutes to perform and can be concluded in a short period of time if no adverse reaction is encountered or lesion is found during the examination; however, if adhesions or bleeding are found during the examination, the examination time may be extended in order to clarify the location or nature of the lesion.
In addition the examination time of colonoscopy is also related to the patient’s bowel preparation, age, underlying disease, tolerance level, and whether endoscopic treatment is performed. For example, when polyps are found during colonoscopy that require treatment such as colonoscopic polypectomy, or when older patients with many underlying diseases tend to be less tolerant, which may result in prolonged examination time.
You need to adjust your state of mind before doing general colonoscopy to avoid anxiety and tension, and too much emotional tension may also cause prolongation of time.
During the examination, the patient needs to lie on the left side, and then the colonoscope is inserted through the anus and the endoscope is used to observe the lesions in the intestines. The process of colonoscopy is relatively simple and requires advance preparation and emptying of the intestinal tract, which should be carried out according to the doctor’s instructions.
