A colonoscopy involves pulling your pants down to the base of your thighs or wearing colonoscopy pants that expose your anus in order to perform the exam.
Colonoscopy is a diagnostic modality mainly used to examine lesions in the intestines by accessing the intestines through the anus. Therefore, to perform a colonoscopy, you need to remove your pants to the base of your thighs or wear colonoscopy pants and expose your anus. Corresponding precautions should be taken before the operation, such as eating less crumbly diet for 3 days before the operation, fasting for 6 hours before the operation, and the need for repeated walking to facilitate defecation after oral laxatives.
Contraindications to colonoscopy include severe cardiac and cerebral disorders, such as severe cardiac arrhythmia, severe respiratory diseases, such as asthma, respiratory failure, CT suggestive of gastrointestinal perforation patients, patients with complete or incomplete obstruction of the colon, pregnant women, a large number of people with ascites, and so on.
