Sigmoidoscopy: Your Questions Answered - Gastroenterology and Hepatology

Sigmoidoscopy inquiry?

Hello Dr.
Su: Recently, my stools have been loose and I noticed that they were thinner yesterday (this has happened before).
However, I usually drink plenty of tea and have been eating green leafy vegetables daily.
Last night, I experienced mild pain in the lower left abdomen and the area where my thigh meets my pelvis, which lasted until morning.
I am concerned about potential issues with my colon and would like to undergo a sigmoidoscopy.
I have a few questions: Can I schedule a sigmoidoscopy at the outpatient clinic for an immediate examination? What are the steps involved in the procedure? How long does it take?

Dr. Su Baojia reply Gastroenterology and Hepatology

Your symptoms are more indicative of a problem with the colon.
Whether a sigmoidoscopy is necessary will be determined by a gastroenterologist.
If it is needed, the physician will typically schedule it for a later time during an outpatient visit.

More Info

Understanding sigmoidoscopy is crucial for anyone experiencing gastrointestinal symptoms, such as changes in bowel habits or abdominal pain. Sigmoidoscopy is a diagnostic procedure that allows a physician to examine the lower part of the colon (sigmoid colon and rectum) using a flexible tube with a camera, known as a sigmoidoscope. This procedure can help identify issues such as inflammation, polyps, or tumors.

When to Consider Sigmoidoscopy
Given your symptoms of unformed stools and intermittent abdominal pain, it is reasonable to consider a sigmoidoscopy. These symptoms can be indicative of various gastrointestinal conditions, including inflammatory bowel disease (IBD), infections, or even colorectal cancer, especially if they persist or worsen. The presence of pain in the left lower abdomen, particularly if it is localized and associated with changes in bowel habits, warrants further investigation.

Scheduling the Procedure
To answer your question about scheduling a sigmoidoscopy, it typically requires a referral from your primary care physician or a gastroenterologist. Depending on the healthcare facility, you may not be able to get an appointment for the procedure immediately. Some clinics may allow you to schedule the procedure directly, while others may require an initial consultation. It is advisable to contact your healthcare provider to discuss your symptoms and determine the best course of action.

Preparation for Sigmoidoscopy
Preparation for a sigmoidoscopy usually involves dietary modifications and bowel cleansing. You may be instructed to follow a clear liquid diet for 24 hours before the procedure and take a laxative or an enema to ensure that your colon is clear of stool. This preparation is crucial for obtaining clear views of the intestinal lining during the examination.

The Procedure
The sigmoidoscopy itself is generally a quick procedure, lasting about 15 to 30 minutes. You will be positioned on your side, and the doctor will gently insert the sigmoidoscope into your rectum and advance it into the sigmoid colon. The scope allows for visualization of the intestinal lining, and if necessary, small tissue samples (biopsies) can be taken for further analysis.

After the Procedure
Post-procedure, you may experience some mild cramping or bloating, which is normal. You will be monitored for a short time before being discharged. It is advisable to have someone accompany you home, especially if sedation is used during the procedure.

Follow-Up
After the sigmoidoscopy, your doctor will discuss the findings with you. If any abnormalities are detected, further testing or treatment may be necessary. It is essential to follow up with your healthcare provider to address any concerns and to discuss the next steps based on the results of the procedure.

Conclusion
In summary, sigmoidoscopy is a valuable tool for diagnosing gastrointestinal issues, especially when symptoms like yours are present. While you may not be able to schedule the procedure immediately, discussing your symptoms with your healthcare provider is the first step. Proper preparation and understanding of the procedure can help alleviate any anxiety you may have. If you have any further questions or concerns, do not hesitate to reach out to your healthcare provider for personalized advice and support.
