General Information
Flexible Sigmoidoscopy is a short procedure, usually performed in the office. It is used for commonly for evaluation of bleeding from the rectum, hemorrhoids, and screening for colon cancer.
Indications
This test is used to evaluate rectal bleeding, colonic masses, screen for colon cancer and look for changes in the lower colon in patients with ulcerative colitis or Crohn's Disease.
Risks
The risks associated with flexible sigmoidoscopy are few. This is due to the short length of colon examined and limited number of interventions with this procedure.
Other Methods of Evaluation
A barium enema can be used to assess most of the area that is inspected by a sigmoidoscopy. However, the rectum and parts of the sigmoid colon are not well seen with the barium enema. A rigid sigmoidoscopy can also be performed. This study does not examine the length of colon performed at sigmoidoscopy. This procedure is usually more uncomfortable. Anoscopy can also be performed, this is even more limited than a rigid scope but has the advantage of being easily done without much preparation.
Before the Procedure ( Preparation)
The preparation for this procedure is usually two fleet's enemas 1 hour before the procedure. The nurses will give specific instructions to you. These can also be found in the Procedure Preparation section of the website.
The Procedure
The procedure, when performed by an experienced physician, requires approximately 5-8 minutes. This study examines the last quarter to last third of the colon. Sedation is not required. If sedation is necessary, the procedure is usually performed in the hospital.
Most patients experience discomfort with the procedure. There is cramping and a bloated sensation after the procedure is completed.
After the Procedure
Most patients have cramps and bloating associated with air instilled in the colon during the procedure. Walking and passing flatus will improve these discomforts.
Immediately after the procedure, you will be informed of the findings. If biopsies were sent, this may take up to one week to return.
A copy of the endoscopic record is sent to all our referring physicians. Thus, your primary care physician will be aware of your procedure, the results and your gastroenterologist's recommendations.
