At PromiseCare Medical Group in Hemet, California, the flexible sigmoidoscopy procedure is utilized to visually examine the lower colon and rectum.
The 15-20 minute procedure involves a patient lying on their left side with their knees drawn toward their chest, and mild relaxation medication may be administered to ensure relaxation.
A flexible tube with a light and camera is then inserted to allow the doctor to inspect for polyps, cancer, or other abnormalities that may be causing symptoms such as bleeding, diarrhea, or abdominal pain.
Overview
Understanding the purpose and process of flexible sigmoidoscopy can help alleviate anxiety and make the experience less intimidating. This diagnostic procedure examines the rectum and lower colon using a flexible tube with a light and camera to investigate unexplained gastrointestinal symptoms such as rectal bleeding, diarrhea, abdominal pain, or weight loss.
The procedure also screens for colorectal cancer and polyps, which can be removed during the exam if detected. Before the procedure, a clear liquid diet and bowel cleansing are required to guarantee clear visualization. This preparation is vital for a successful exam.
The procedure typically lasts 15 to 20 minutes, during which the patient is awake, although mild relaxation medication may be offered. The flexible tube is inserted, and the camera captures images of the lower colon, allowing for the identification of any abnormalities.
Understanding the purpose and process of flexible sigmoidoscopy can help manage anxiety and make the patient feel more comfortable during the screening.
Types
Deep within the domain of gastrointestinal diagnostics, two primary types of sigmoidoscopy emerge: flexible sigmoidoscopy and rigid sigmoidoscopy.
Flexible sigmoidoscopy is the more commonly performed procedure because it utilizes a flexible tube to examine the sigmoid and part of the descending colon, offering a broader visualization scope. Typically, sedation isn’t required, making it a more accessible option.
Rigid sigmoidoscopy, on the other hand, employs a non-flexible tube primarily for examining the rectum. Its limitations in diagnostic capability make it less frequently used.
Flexible sigmoidoscopy is often performed in outpatient settings, allowing for greater convenience and comfort. Within the space of flexible sigmoidoscopy, there’s also the option of high-definition sigmoidoscopy. This advanced imaging technology provides improved visualization of the colonic mucosa, further enhancing diagnostic capabilities.
Understanding the distinctions between these types of sigmoidoscopy can empower individuals to make informed decisions about their gastrointestinal health. The nuances of each type can guide individuals toward the best course of action.
Why it’s done
Flexible sigmoidoscopy is a procedure used to investigate unexplained gastrointestinal symptoms, such as rectal bleeding, abdominal pain, or changes in bowel habits.
It’s a tool for detecting polyps or cancer in the lower part of the colon and is often used as part of colorectal cancer screening.
Routine screening is essential, especially for individuals 45 or older. Those with a family history of colorectal issues may require more frequent screenings.
Flexible sigmoidoscopy can identify and address gastrointestinal symptoms, providing a deeper understanding of the body’s inner workings. It may also be used as a follow-up to abnormal test results, allowing for a direct examination of the lower colon.
Undergoing a flexible sigmoidoscopy is an essential step toward early detection and intervention, enabling individuals to take control of their well-being.
This procedure plays a significant role in maintaining good health and addressing potential issues before they become severe.
Who it’s for
Flexible sigmoidoscopy is typically recommended based on age, medical history, and risk factors. For those 45 or older, this procedure is a crucial part of routine colorectal cancer screening, as current guidelines recommend.
However, it’s not just about age – unexplained gastrointestinal symptoms like rectal bleeding, abdominal pain, or changes in bowel habits may also prompt a flexible sigmoidoscopy to uncover the cause.
A family history of colorectal cancer or a personal history of inflammatory bowel disease may lead to a recommendation for this procedure earlier and more frequently. Abnormal results from stool tests or imaging studies may also require a flexible sigmoidoscopy for a closer look.
As individuals age, their health status and risk factors are assessed to determine if continued screening is necessary, especially after 75. By staying on top of screenings, individuals can take control of their health and reduce their risk of colorectal cancer.
A flexible sigmoidoscopy may be recommended based on individual health needs.
Risks
Beneath the surface of this highly effective screening tool, flexible sigmoidoscopy carries inherent risks that, although rare, warrant careful consideration. Weighing the benefits of this procedure also requires awareness of the potential complications that may arise.
One of the most significant risks is perforating the intestinal wall, which occurs in approximately 1 in 1,000 cases; this may require surgical intervention. It’s vital to be aware of the signs of severe symptoms, such as persistent abdominal pain, fever, or ongoing bleeding, which may indicate complications that require medical attention.
Additionally, minor bleeding can occur, especially if polyps are removed. While most cases are self-limiting and don’t require additional treatment, it’s essential to monitor for any unusual symptoms.
Mild discomfort, such as cramping, bloating, or gas pain, may also be experienced following the procedure. Adverse reactions to anesthesia are possible, although sedation is typically not necessary for flexible sigmoidoscopy.
Understanding these risks can help navigate the process and ensure necessary medical attention is received if complications arise. Being aware of the potential dangers enables informed decisions about health.
How you prepare
Preparation for a flexible sigmoidoscopy is crucial to ensure a successful procedure. The bowel prep process begins with a clear liquid diet at least 24 hours before the exam, allowing the colon to empty.
A bowel preparation regimen, which may include laxatives or enemas the night before, follows to facilitate complete colon cleansing.
Inform your healthcare provider about any medications you’re taking, especially blood thinners or medications for diabetes, to determine if any adjustments are necessary.
To prepare for a flexible sigmoidoscopy, take the following steps:
- Arrange for post-procedure transportation, as you may experience mild discomfort and won’t be able to drive immediately.
- Follow bowel prep instructions carefully to make sure results are precise.
- Disclose your medications to avoid any complications.
- Adhere to a clear liquid diet to guarantee a successful colon cancer screening.
Proper preparation is critical to a smooth and effective procedure.
What you can expect
During a flexible sigmoidoscopy, the exam room becomes a flurry of activity as medical professionals prepare you for the procedure.
The procedure is performed as you lie on your left side, knees drawn toward your chest. The sigmoidoscope is gently inserted into your rectum. The goal is to examine the lower colon, and you may feel mild discomfort, bloating, or gas as air is introduced to inflate the colon for better visibility. The procedure usually takes about 15 to 20 minutes, possibly longer if biopsies are taken.
If a biopsy is required, you might feel a slight pinch as the sigmoidoscope is navigated. The air used to inflate your colon may cause some discomfort, but this typically subsides once the procedure is complete.
After the exam, preliminary findings may be shared, but biopsy results will take several days to return. Most patients can resume normal activities and diet immediately, although it’s crucial to monitor for unusual symptoms, such as prolonged bleeding or severe abdominal pain.
Results
Receiving the results of a flexible sigmoidoscopy can be both enlightening and unsettling. As one awaits the findings, the mind may wander to the what-ifs.
But what does it mean if the results reveal something abnormal?
The following outcomes may occur:
- Polyps or lesions are found: A follow-up colonoscopy may be recommended to evaluate further and possibly remove those growths.
- Biopsy results are pending: It may take several days to process, leaving one waiting for answers.
- Bleeding occurs post-procedure: Light bleeding may happen if tissue is removed, but this is generally considered normal and should resolve within a few days.
- Regular surveillance is necessary: Depending on the findings and individual risk factors, regular screenings may be required to maintain a healthy gastrointestinal system.
Flexible sigmoidoscopy results can be a turning point in one’s journey toward a healthier state.
