Comprehensive Gastrointestinal Health specializes in the following procedures or tests. If you’re preparing for your procedure or would like to learn more about each one, click on the tab to get detailed information, helpful downloads, and preparation materials.
What is a colonoscopy?
A colonoscopy involves looking at the colon from inside the body using a long, thin, flexible tube with a tiny camera on the end, through which the doctor can view your whole colon and rectum. The colonoscope is inserted into the anus and advanced through the entire colon and possibly a short distance into the small intestine (called the terminal ileum).
The image on the TV monitor is magnified many times so the doctor can see small changes in tissue. The colonoscope contains channels that allow the doctor to obtain biopsies (small pieces of tissue), remove polyps, and to introduce or withdraw fluid or air. If the doctor sees areas of inflammation or needs a sample of tissue to look for microscopic changes, biopsies or samples of tissue can be obtained.
What is an endoscopy?
An endoscopy (also called an upper GI scope or EGD) is a procedure that uses a long, thin, flexible tube with a tiny camera on the end, through which the doctor can examine your esophagus (swallowing tube), stomach, and the duodenum (the first part of the small intestine).
The image on the TV monitor is magnified many times so the doctor can see small changes in tissue. If the doctor sees areas of inflammation, ulcers, polyps, or tumors or needs a sample of tissue to look for microscopic changes, biopsies or samples of tissue can be obtained.
How long does an endoscopy last?
The procedure is generally 5-15 minutes long. An anesthesiologist administers medications through the IV line. Most people have a deep sleep during the examination and are unaware that it was even performed.
No solid food after midnight the night before your procedure.
You may have clear liquids up until 3 hours before the procedure. This includes coffee and tea (no milk or cream), Gatorade/Propel, juice without pulp, soda, and water.
For the procedure to be thorough and safe, it is necessary for your stomach and duodenum to be empty. Three hours before your scheduled procedure time, absolutely nothing more to eat or drink!
Contact the physician who prescribes the medication to determine how to take it before and after your procedure.
Please do not assume that you can safely follow the same medication adjustments that have been made for your previous procedures.
These medications include:
If you are taking aspirin recommended by one of your doctors, please CONTINUE to take it.
If you do not have a heart, blood vessel, or clotting disorder and you are taking aspirin on your own without a doctor’s advice, please stop taking aspirin 5 days before the procedure.
Schedule your procedure for the morning if possible.
If you control your diabetes with ORAL medications alone, do NOT take any diabetes medications on the day of your procedure. You may resume your medications after the procedure is complete and you have eaten.
If you control your diabetes with INSULIN alone, do NOT take any insulin on the day of your procedure. You may resume your medications after the procedure is complete and you have eaten.
If you control your diabetes with BOTH INSULIN and ORAL medications. Follow both sets of instructions as above.
If you utilize an INSULIN PUMP, please contact your endocrinologist for specific instructions.
Check your blood sugar frequently the morning of your procedure.
If you take medications for HIGH BLOOD PRESSURE, IRREGULAR HEART BEAT, SEIZURES, ASTHMA, THYROID, or PREDNISONE, then please take your medication with a sip of water the morning of your procedure.
Other medications can wait until after the procedure is completed.
Check your blood sugar frequently the morning of your procedure.
The first and last names of all doctors you would like us to send a copy of procedure report.
Someone to drive you home.
Your insurance cards.
Your medication list.
Every effort will be made to keep your appointment at the scheduled time, but in medicine, unexpected delays and emergencies may occur and your wait time may be prolonged. Â We give each patient the attention needed for his or her procedure.
Typically we run on schedule and the duration from the time of drop off until you leave to go home runs approximately 2 hours.
After the administrative check in, a nurse will ask questions to ensure the patient understands the procedure and the reason it is planned.
The nurse will start an intravenous line (insert a needle into a vein in the hand or arm; feels similar to having blood drawn) to administer medications.
The vital signs (blood pressure, heart rate, and blood oxygen level) will be monitored before, during, and after the examination. The monitoring is not painful, though the first time the blood pressure cuff inflates it can be uncomfortable for 20-30 seconds.
Vital sign monitors will be placed and values checked again before starting the sedating medications.
All patients will be given oxygen during the examination through plastic tubing prongs aimed into their nostrils.
You will position yourself to be lying on your left side.
A plastic mouth guard will is placed between the teeth to prevent damage to the teeth and scope.
The anesthesiologist will administer medications through the IV line. Most people have a deep sleep during the examination and are unaware that it was even performed.
The procedure is generally about 5-15 minutes long.
You will be recovering for approximately 30-40 minutes.
You may feel slightly bloated and belching will help to relieve this sensation.
You may have a sore throat. This usually lasts for less than 48 hours.
Due to the lingering effects from the sedation medication, you may not remember the physician speaking to you. If you gave permission prior to the procedure, the doctor will review the findings with your family member or responsible adult that accompanies you.
You will be able to eat and drink right after the procedure is completed.
You will NOT be able to drive or return to work for the remainder of the day. Although you will be awake by the time you are discharged, the sedative medications cause changes in reflexes and judgment that cause a person to feel well but can interfere with the ability to make decisions, similar to the effects of alcohol.
If your symptoms are mild and you have no fever, feel free to use Tylenol or other over the counter cold medications and proceed as scheduled.
If you have a fever, shortness of breath, severe cough or wheezing, please call and reschedule the procedure for when you are feeling better.
If you arrive the day of the procedure with these more concerning symptoms, the anesthesiologist may cancel the procedure in the interest of your safety.
No problem at all. Your doctor will confirm just prior to the procedure what you are comfortable with.
Although you may not remember the details of the procedure findings due to the sedation, all of the information is typed up and attached to the photos that were taken. If you have any questions later on when you are clear-headed, just call the office and we can review the details.
Endoscopy is a safe procedure and complications are rare, but they can occur.
Risks of endoscopy include:
What is a flexible sigmoidoscopy?
A flexible sigmoidoscopy (also called a “flex-sig” for short) allows the doctor to examine the end part of the colon and rectum.
A long, thin, flexible tube with a tiny camera on the end is inserted into the anus and advanced through the lower third of the colon and rectum. The scope blows air to inflate the colon to allow the doctor to more carefully examine the colon.
The doctor can insert instruments through the scope that can sample the colon tissue or remove polyps (abnormal growths from the wall of the colon).
Will I feel anything during the procedure?
Most individuals will be fully awake during the procedure because it is so short, approximately 10 minutes in duration.
If you are not sedated, then you will be able to feel the small tube being inserted and feel pressure, bloating, or slight cramping as the scope is advanced the short distance. Some individuals will receive sedating medications through an IV line and will not be likely to feel or remember any part of the procedure.
What is a capsule endoscopy?
Capsule endoscopy allows for examination of the small intestine. This middle portion of your gastrointestinal tract, which includes three portions of the small intestine (duodenum, jejunum, ileum), cannot be easily reached with standard endoscopy methods.
How is a capsule endoscopy performed?
You will be given a pill sized video camera for you to swallow. This camera has its own light source and takes pictures of your small intestine as it passes through. These pictures are sent to a small recording device you have to wear on your body.
Your doctor will be able to view these pictures after they are downloaded. This may provide information on structural changes in your small intestine.
Why is a capsule endoscopy done?
The most common reason for doing capsule endoscopy is to search for a cause of bleeding from the small intestine. It may also be useful for detecting polyps, Crohn’s disease, ulcers, and tumors of the small intestine.
What is it?
The Bravo pH monitoring system is a simple way to evaluate gastroesophageal reflux symptoms. The Bravo capsule
will continually measure the pH levels in your esophagus and will wirelessly transmit data to the Bravo pH recorder
that is worn on your belt.
How does it work?
Your physician will place the miniature pH capsule into your esophagus while under anesthesia. The capsule only
takes a moment to be placed and is temporarily attached to the wall of your esophagus. The capsule will monitor your
symptoms as you resume your regular activities. Once the test is completed, you will need to return the recording
device to our office. Your physician will be able to download your results for analysis and diagnosis.

ADENOMA DETECTION RATE
The detection goals that have been established are to find at least one adenomatous polyp in:
NOTE: for the most accurate methodology, values are calculated only for patients age >50 for their first-time screening or surveillance examinations after 10 years; surveillance examinations for a history of polyps or family history of colon cancer/polyps and other symptomatic indications are excluded.
Dr. Troy’s Adenoma Detection Rate:
Dr. Nathanson’s Adenoma Detection Rate:
Prior to his joining us at Comprehensive Gastrointestinal Health, Dr. Nathanson had calculated adenoma detection rates that also were significantly higher than standard quality goals. Because these numbers were calculated using a different methodology, Comprehensive Gastrointestinal Health has decided that, rather than publish these rates, it will measure Dr. Nathanson’s adenoma detection rate using the procedures he performs in our endoscopy suite by the same method that is used to calculate Dr. Troy’s rate. This data will be compiled and updated on our website.
