How to do painless electronic colonoscopy

Colonoscopy is quite painful because when inserting this thin tube into the intestine, there will naturally be some uncomfortable feeling of foreign objects entering the body. Therefore, many people choose to undergo painless electronic colonoscopy. This examination can greatly reduce the patient's pain, and it will not wear the surface or cause complications. What is this examination like and how can we make it easier for patients?

Overview

Electronic colonoscopy is a method of inserting a colonoscope through the anus into the ileocecal cavity and observing colon lesions from the mucosal side. It is currently the best choice for diagnosing colorectal mucosal lesions. It transmits the image of the colon mucosa to the electronic computer processing center through the electronic camera probe installed at the front end of the colonoscope, and then displays it on the monitor screen. It can observe subtle changes in the colorectal mucosa, such as cancer, polyps, ulcers, erosions, bleeding, pigmentation, varicose and dilated blood vessels, congestion, edema, etc., and the image is clear and realistic.

Electronic colonoscopes can also use the instrument channel of the colonoscope to insert biopsy forceps to obtain rice-grain-sized tissue for pathological section testing or other special staining, and conduct histological characterization of the nature of mucosal lesions, such as the degree of inflammation, the degree of differentiation of cancer, etc. Further grading is helpful in understanding the severity of the lesions, guiding the formulation of correct treatment plans or judging the effectiveness of treatment. Endoscopic treatment can also be performed on some colon diseases or lesions such as polyps, bleeding, foreign bodies, etc. through the colonoscope instrument channel.
