The upper endoscopy procedure takes only about 15-30 minutes. The colonoscopy procedure takes about 30-45 minutes on average.Because time before your endoscopy and a period of recovery, you and your escort should expect to spend 90-120 minutes at our facility.
1. Timing- We like to bring the patient’s driver/family member back as soon as the procedure is done so that this person can be present to hear what the doctor did during the procedure. This is very important as the patient is usually still under the influence of medication and will not remember this important conversation. The length of procedures can be unpredictable at times and we may be done sooner than we thought, if the driver is not here then the information on what happened will not be heard by someone else that is coherent.
2.Safety - If something happens we would want someone here to discuss what is going on with the patient.
3.Comfort - We like our patients to go home after their procedure to the comfort of their own homes. That way they can pass any extra air without feeling embarassed and can sleep for a few hours until the medication completely wears off. If we are finished before the driver arrives then due to space the patient may have to wait in the waiting room which is not the most comfortable place to be after a procedure.
The American Heart Association has developed guidelines for identifying need for antibiotics before endoscopic procedures. These may differ from your dentists requirement for antibiotics before dental work. Discuss your need for pre-procedure antibiotics with your doctor if you have any concerns. They are administered primarily for patients who have artificial heart valves.
You will NOT be given a general anesthetic as when a patient has major surgery. You will be given medication through an IV site that will cause relaxation. Many patients have no memory of their procedure when completed due to the medications’ effects.
Medicines are given in the vein through an IV port placed in your hand or arm. Medication dosage and type may vary depending on your individual needs. Generally, a narcotic medication such as Demerol or Fentanyl is used in addition to a drug called Versed, which has effects similar to Valium. For an upper endoscopy, a spray may be used to numb your throat and to help prevent gagging. It contains a medicine very similar to that used by your dentist for dental work.
Upper endoscopy is generally painless except for a feeling of mild transient fullness as the scope is passed through the mouth and throat. The majority of colonoscopy patients note no discomfort during the procedure. A few patients will remember some mild cramping and discomfort during the procedure. A small number of patients will experience significant discomfort during the exam. There is usually no pain after the procedure other than mild bloating in the first hour as gas passes out of the colon.
The medicines you are given have much the same effect on the brain function as alcohol. In addition, the effects of the medicine stay in the body for several hours and will affect judgment and reaction time long after the patient feels the medicine is gone. You may take a medical taxi home provided you have an escort to assure that you arrive safely at your destination.
In general, all the effects of your sedation will be gone by the morning after your procedure. You will have no restrictions at that time.
Seeds may remain in the bowel following the preparation for colonoscopy. During the procedure they may be suctioned into the endoscope and damage the instrument. Avoiding seeds for a week before the procedure will help prevent this problem.
Your doctor will talk to you after your procedure. He/she will tell you at that time what was seen. If biopsies are taken, or polyps removed, you will know the results in 2-3 weeks. You will be contacted by phone or letter about your results with instructions for follow-up, if necessary. You will receive results even if the pathology is normal. If you have not heard from us within four weeks, call the office to let us know. We will give you your results at that time.
One of the sedation medicines (Versed) you are given causes amnesia. After your procedure you may be alert, able to follow commands and ask questions, but you may not remember any events. Your doctor will talk with you after your exam. We encourage your escort to be with you at that time so they can hear the discussion in case you have any questions later. The day after your exam, one of our nurses will be calling to check how you are doing and can answer questions for you at that time or refer you to your physician if appropriate.
If you use the large volume preparation such as GoLyte, NuLyte, CoLyte, the following should be considered:
After mixing the solution at noon, place in the refrigerator. When you start the prep in the evening, take about 2 quarts out of the refrigerator and drink as scheduled. When the 2 quarts are gone, refill the container and continue this pattern until all the prep is taken. This will keep the solution cold enough to help keep the taste from getting too salty but not so cold that it will chill your body. Occasionally, you may feel chilled.
Ten percent of patients will have nausea and vomiting with the prep. If you are becoming nauseated, stop the liquid and wait 45-60 minutes. Restart the prep at one glass every 15-20 minutes until it is gone. If you continue to vomit, phone the doctor on call (979)776-4600.
The amount of time needed for the liquid to cause diarrhea varies, it can take up to 4 or more hours.
Some residual liquid in the colon is normal after preparation for colonoscopy. Since the body continues to produce bile even if you do not eat, this bile will color the liquid yellow. Small to moderate amounts of clear or cloudy yellow liquid eliminated from the rectum is normal the day of colonoscopy.
Colon polyps are small growths that develop on the inside wall of the colon. These start very small (1-2 millimeters, the size of a small ant) and slowly grow larger. Many are shaped like a mushroom or a cauliflower. It takes years for the average polyp to reach 1 cm in size (the size of a pea). The larger the polyp, the higher the cancer risk.
Most polyps cause no symptoms. Most polyps can be removed at the time of your colonoscopy. You will generally feel no pain or sensation when polyps are removed. There is a very small risk of bleeding in the colon at the polyp removal site, which could require hospitalization or blood transfusion. Rarely polyp site bleeding will require surgery.
All polyps that are removed are sent to the pathology lab for evaluation. Two types of polyps can be found. Hyperplastic polyps have no risk of recurrence or malignancy (formation of cancer). Adenomatous polyps are pre-cancerous and do tend to recur elsewhere in the colon and therefore require a follow-up exam. Your doctor cannot visually distinguish hyperplastic from adenomatous polyps, so microscopic examination is required. Your doctor will contact you by phone or letter about results if a polyp has been removed. If you have not heard from your doctor in 4 weeks, please call the office for results.
Most people are able to pass all the air out of their GI tract within 1-2 hours after the procedure. Walking about or lying on the left side may help to eliminate the air.
Unless instructed otherwise, you should wait 2 hours after your procedure to have a meal to be assured that all gas has passed out of the GI tract and you are alert enough to eat.
Unless instructed otherwise, you will have no dietary limitations after your procedure. You should drink no alcohol for 24 hours because of the sedation medicine you were given for your procedure.
You will be given a medicine by spray to the back of your throat to prevent gagging. Your throat will feel numb for 1-2 hours. You may have mild soreness for the rest of the day, especially if you underwent dilatation. Severe throat pain or pain that persists for more then 48 hours should be reported to your doctor.
Colon cancer rarely shows symptoms until much later in the disease. It is the second-leading cause of cancer deaths in the U.S., which is why screening has become so important.
