Instructions for Flexible Sigmoidoscopy (Flexi)

Please report to: Lincoln Surgery Endoscopy Services at 1730 S. 70th St   Ste 120 Entrance D

A sigmoidoscopy is the visual examination of the inside of the rectum and sigmoid colon, using a lighted, flexible video endoscope.  Unlike the colonoscopy that visualized the whole colon which is approximately 5-6 feet, this procedure usually only visualized the last part of the colon which is approximately 1-2 feet.

There are several reasons why a Flexi is performed. These could include but are not limited to; bleeding, diarrhea, colitis, abdominal pain, rectal pain, abnormal x-rays findings, and/or a follow up from a previous diagnosis (polyp, cancer, etc.)

 A nurse from Lincoln Surgery Endoscopy Services will be contacting you within a week before your scheduled procedure. Our preop phone calls are generally made in the afternoon, due to our nurses being involved with morning procedures.  Please plan on this call taking approximately 10-20 minutes depending on your medical information. This call is very important, so that we may obtain your information and answer any questions you have about your upcoming procedure.     

While we may have notified your insurance company, it is your responsibility to contact your insurance company regarding your benefits and how this procedure will be paid.


Preparing For Your Exam

Five days prior to your procedure:

  • STOP your medications that have blood thinning effects. Examples: Motrin, Ibuprofen, Aleve, Celebrex, and arthritis medications. Tylenol and Aspirin are okay.  (If you are on Coumadin, Plavix, Xarelto or any other anticoagulant/antiplatelet medication you must contact your Primary Care Physician for instructions.)                                                                                
  • Diabetics: If you are diabetic and take insulin, call your Primary Care Physician for instructions. Please check your blood sugar/glucose before leaving your home.

One day before your procedure:

  • NO FOOD all day!  Drink only CLEAR LIQUIDS (see below) starting when you wake up in the morning, throughout the entire day and up until 2 hours before your scheduled admit time.  The more clear liquids you drink, the better the prep solution will work and the better you will feel.  Below is a list of clear liquids that you may have.  Please note that no red dye is allowed (no red Jell-O, red drinks, etc.).  Please limit all dark beverages such as tea, soda, coffee, etc. to 2 cups daily.
