Colonoscopy
Hello Doctor: Previously, I experienced rectal bleeding, so I underwent a colonoscopy this week.
The results showed internal hemorrhoids, and there were no polyps in the intestines.
I did take a laxative before the examination.
During the procedure, I observed my intestinal condition on the colonoscopy screen; most of it appeared pink with no foreign objects, but in a small portion of the intestine, there was some residual yellow, stool-like liquid.
However, after consulting with the doctor, they believed the bowel preparation was sufficiently clean and there were no issues.
I would like to ask, during a colonoscopy, should the entire intestine be completely clear and appear pink? Is it normal to have residual yellow liquid in a small part of the intestine? Is it necessary to repeat the procedure?

It is not necessary to completely clear the intestines; having some residual liquid stool is normal.
Additionally, the physician will address this and ensure a clear view, so there is no need for excessive concern.

During a colonoscopy, the goal is to have a clear view of the colon's lining to identify any abnormalities such as polyps, inflammation, or other issues. The preparation for this procedure typically involves a bowel cleansing regimen, which usually includes a prescribed laxative to ensure that the intestines are as clear as possible. However, it is not uncommon for some residual fluid or stool to remain in the colon even after thorough preparation.
In your case, the presence of some yellowish, liquid-like residue in a small portion of the colon is generally considered normal. The colon is a complex organ, and complete evacuation may not always be achievable, especially in the distal parts of the colon where the anatomy can make it more challenging to clear all contents. The fact that the majority of your colon appeared pink and free of abnormalities is a positive sign and suggests that the preparation was largely effective.
It's important to understand that the colon can retain some fluid or stool, particularly if the bowel prep was not entirely complete or if there are anatomical variations. The presence of residual fluid does not necessarily indicate a problem, especially if the physician performing the colonoscopy assessed the situation and deemed it acceptable. Medical professionals are trained to interpret these findings in the context of the overall examination, and if they felt that the colon was adequately prepared for the procedure, then there is likely no cause for concern.
Regarding your question about whether the colon should appear entirely clear and pink during a colonoscopy, the answer is that while a clean colon is ideal, some residual material can be normal. The key is that the physician can still visualize the colon's lining effectively to identify any potential issues. If the physician has indicated that the examination was satisfactory and there were no concerning findings, then there is no need for a repeat colonoscopy solely based on the presence of some residual fluid.
In summary, while the goal of bowel preparation is to achieve a clear view of the colon, some residual fluid can be normal and does not typically warrant a repeat procedure unless there are other concerning symptoms or findings. If you have ongoing concerns about your bowel health or experience symptoms such as persistent bleeding, changes in bowel habits, or abdominal pain, it is essential to discuss these with your healthcare provider for further evaluation and management. Regular follow-up and communication with your physician are crucial for maintaining gastrointestinal health, especially after experiencing symptoms like rectal bleeding.
