Flexible Sigmoidoscopy
Flexible sigmoidoscopy is a procedure used to examine the lower part of the colon (sigmoid colon) and rectum. This test helps detect early signs of colorectal cancer, polyps, and inflammatory bowel disease, offering a less invasive alternative to a full colonoscopy.
Overview
Flexible sigmoidoscopy involves inserting a flexible, lighted tube through the rectum to examine the lower part of the colon (sigmoid colon). The procedure allows the detection of polyps, inflammation, and cancer in the rectum and sigmoid colon. Unlike a full colonoscopy, this test focuses on the lower bowel and typically takes 10 to 20 minutes.
Purpose of the Procedure
Flexible sigmoidoscopy examines the lower part of the colon and rectum, detecting polyps, cancer, and signs of inflammatory bowel disease, allowing for early intervention and diagnosis.
How to Prepare
For flexible sigmoidoscopy, patients are required to fast before the procedure. An enema or laxative may be prescribed to cleanse the lower bowel. Patients are encouraged to inform their doctor about any history of diverticulitis or recent abdominal surgery.
What to expect after
Flexible sigmoidoscopy may result in slight cramping or bloating, which resolves within a few hours. Patients can return to regular activities immediately unless sedation was used. Minor bleeding may occur if biopsies or polyps were removed.
Complications & Risk
Flexible sigmoidoscopy is a low-risk procedure. However, minor bleeding can occur if biopsies are taken or polyps are removed. Perforation of the colon is rare but can lead to more severe complications requiring surgical intervention. Cramping or bloating is common but temporary.
Results and Follow-up
Flexible sigmoidoscopy results are often shared right after the procedure. If polyps are removed or biopsies are taken, pathology results are typically available within a week. Depending on the findings, the doctor may recommend routine screenings or a full colonoscopy if abnormalities are detected in the sigmoid colon.
