The Colon Prep:

On the Day Prior to our Colonoscopy Procedure

At 3 pm or Later – Begin drinking your Colon Prep:

  1. Take your mixed Colon Prep out of the refrigerator and drink an 8 oz glass every 15 minutes until finished
  2. Do Your Best – Everyone has a different system – The Colon Prep may work quickly or may take several hours to have an effect. Stay near a restroom for the evening
  3. Having Problems – Sometimes patient have problems with nausea or pain while taking the prep. Call our center early in the day if having problems. We frequently call in medications to help calm your stomach and reduce cramping and nausea.
  4. If you already know that drinking the colon prep is difficult, we can call in medications to make prevent nausea and discomfort.

Important Considerations

Prior to a colonoscopy, it is important to know if the patient has any unusual anatomy due to a prior colon surgery, prior abdominal pelvic surgeries, and abdominal hernias or if the patient has a colostomy.

It is also important to understand if the patient has any other medical conditions that may make colonoscopy higher risk.

Examples of high risk colonoscopy patients include:

  • A history of implanted cardiac defibrillator
  • Underlying diabetes
  • Hypertension
  • Coronary artery disease
  • Lung disease
  • A history of difficult intubation for general anesthesia   
  • Patients taking anticoagulation medications prior to colonoscopy (this needs to be discussed with the medical team prior to scheduling a colonoscopy procedure)

The Procedure

Generally speaking a colonoscopy is a very safe and effective procedure for reducing the likelihood of colon cancer, while also being a very useful tool in diagnosing a wide variety of medical conditions involving the lower intestines.

Checking In to the Hospital or Endoscopy Center:

On the day of the procedure, patients should arrive 1.5 hours before their scheduled appointment time.  Most centers want to meet your driver at the time of check in to confirm that patients will have a ride home.  Health centers often cancel your procedure, if the person giving the patient a ride home is not present.  After your check In at the procedure center, you will be escorted to a pre-operative room and meet the nurses, anesthesia, and physician team performing the procedure.  An IV will usually be placed in the hand or arm. After you have been examined, and if no unusual problems are identified, you will be asked to consent to the procedure. This is a good time to ask any additional questions and review the risk and benefits of the colonoscopy.

Prior to the Procedure:

After signing consent forms, you will be transported to the procedure room.  Once in the procedure room, typically patients are placed on their left side and when comfortable, IV sedation is given.  Most centers are using Propofol as their sedation drug of choice. Patients can expect to be asleep through their entire exam.

Colonoscopy Procedure:

While the patient is asleep, the physician will place the flexible colonoscope into the lower colon thru the rectum and carefully advance the scope until reaching the small intestines. Our landmark is the cecum and terminal ileum. Once we have reached these locations, the scope will be slowly withdrawn and mild insufflation of air and water rinse are used to improve the view of the colon lining.  As the colonoscope is withdrawn through the colon, we carefully evaluating for any evidence of polyp, cancer, diverticulosis, inflammation or any other visible abnormality.  It is very common to obtain biopsies or remove a polyp during the procedure.  Lastly, a careful inspection of the rectum is performed to evaluate for internal and external hemorrhoids.  The endoscope is removed and the patient is taken to the recovery area for further monitoring.  Most colonoscopies take no longer than 30 minutes in total.

Colonoscopy Recovery:

After completing the colonoscopy, patients are taken to a recovery room and monitored by the nursing staff.  Most patients wake up fairly quickly and after approximately 30 minutes, and will be discharged from the center.  Before discharge, the doctor will give a brief review of the procedure findings and a plan for follow up.

Diet After Procedure:

We recommend going slow with food following the colonoscopy procedure.  We recommend that patient’s do not eat until they are sure their system is ready. A liquid diet would be best, for example: soup, shakes and/or smoothies, being careful to avoid rich, heavy foods.  As the day progresses and if you are not feeling any pain, nausea, or discomfort, you may return to eating a normal diet.


Fortunately, the risk of a serious complication following colonoscopy is very low.  Multiple studies have shown a complication rate of approximately .5 – 2.8 per 1000 procedures and 85% of the complications were related to polyp removal.  The mortality rate of colonoscopy varies but has been estimated at 0.007%.  Patients over the age of 80 appear to have a higher rate of serious complication when compared to individuals aged 66-69.  Having additional medical problems such as stroke, lung disease, atrial fibrillation or heart failure also raise risk.

Other potential complications can be related to sedation including; drug reaction and over sedation, complications related to the prep and bleeding related to polypectomy, which may occur immediately or even 5-7 days later.  Delayed bleeding from colonoscopy has been reported as late as 29 days following procedure.  Perforation rates of the colon varies in different studies, but has been estimated to occur 0.01 -2.1% of cases during a screening exam.

“Post polypectomy syndrome” has been described and is characterized as patients experiencing low level fever, abdominal tenderness, and elevated white blood cell count for 1-5 days following a colonoscopy with polyp removal. Symptoms are caused by the burning and removal of polyps during the procedure and local irritation and inflammation of the colon wall, which is not due to a perforation.  This syndrome does not require surgical intervention and is generally treated with hydration, antibiotics, and bowel rest with close observation.

Patients are encouraged to call the doctor’s office at any time for any problems related to a procedure.

Call your medical team if you are experiencing any of the following symptoms:

  1. Bleeding
  2. Abdominal pain
  3. Abdominal tenderness
  4. Fever or chills
  5. Nausea or vomiting

Quick identification of the problem is the most important factor in managing complications following your procedure.
