Introduction
Colonoscopy is a procedure in which a colonoscope is inserted through the anus into the terminal ileum, allowing direct visualization of colonic lesions from the mucosal side. If this examination is required, it is recommended to go to a正规 hospital and have the procedure performed under the guidance of a qualified physician to avoid potential injury caused by improper operation. If any discomfort occurs during the examination, it is advisable to inform the doctor promptly.
Generally, colonoscopy is a procedure in which a colonoscope is inserted through the anus and advanced along the intestinal lumen into the terminal ileum, allowing direct mucosal observation of the colon for detecting lesions. The specific steps are as follows:
1. Prior to the examination, the patient takes prescribed laxatives to completely empty the bowel.
2. The patient lies on their left side with knees bent, exposing the anus.
3. The physician performs a digital rectal examination using one or two fingers to check for conditions such as hemorrhoids or anal fissures.
4. The physician inserts the lubricated tip of the colonoscope at an angle into the anus using the right hand.
5. Using the left hand to control the scope, the physician slowly advances the colonoscope along the intestinal lumen while observing the interior of the colon and its mucosa, continuing until reaching the terminal ileum.
If this examination is needed, it is recommended to visit a reputable medical facility and undergo the procedure under the guidance of a qualified physician to avoid potential injury due to improper operation. If any discomfort occurs during the procedure, inform the doctor promptly. Maintaining healthy lifestyle habits in daily life contributes to overall health.
