Dr. Vedant H. Karvir - Gasteroenterologist in Boisar

An upper GI endoscopy is a problems in procedure to diagnose and treat your upper GI (Gastrointestinal) tract. The upper GI tract includes your food pipe (esophagus), stomach, and the first part of your small intestine (the duodenum).
This procedure is done using a long, flexible tube called an endoscope. The tube has a tiny light and video camera on one end. The tube is put into your mouth and throat. Then it is slowly pushed through your esophagus and stomach, and into your duodenum. Video images from the tube are seen on a monitor.

The most common reasons for upper Endoscopy include:

• Unexplained discomfort or pain in the upper abdomen.
• GERD or gastroesophageal reflux disease (often called heartburn).
• Persistent nausea and vomiting.
• Upper gastrointestinal (GI) bleeding (vomiting blood or blood found in the stool that originated from the upper part of the GI tract). Bleeding can be treated during the endoscopy.
• Iron deficiency anemia (low blood count associated with a low iron level in the blood) in someone who has had no visible bleeding.
• Difficulty swallowing; food/liquids getting stuck in the esophagus during swallowing.

You may be asked not to eat or drink anything for up to eight hours before the test. This usually means no food or drink after mid night. It is important for your stomach to be empty to allow the doctor to visualize the entire area.

You should arrange for a friend or family member to escort you home after the examination. Although you will be awake by the time you are discharged, the medications used for sedation may cause temporary changes in your reflexes and judgment and interfere with your ability to drive or make decisions.

You will be asked to lie on your left side. This provides the best view of the stomach.

• Your blood pressure, pulse, breathing, and blood oxygen levels will be monitired during the test. An intravenous (IV) needle will be placed in your arm to provide a sedative. Sedatives help you stay relaxed and comfortable during the procedure. In some cases, the procedure can be performed without sedation. You will be given a liquid anesthetic to gargle or spray anesthetic on the back of your throat.
• The doctor will carefully feed the endoscope down your esophagus and into your stomach and duodenum. A small camera mounted on the endoscope will send a video image to a monitor, allowing close examination of the lining of your upper GI tract.
• Air or carbon dioxide gas is gently introduced through the endoscope to open the esophagus, stomach, and intestine, allowing the endoscope to be passed through these areas and improving the doctor's ability to see completely. The air may give you some discomfort or pressure. This is not harmful, this feeling is normal and should go away soon after the test. The procedure typically takes 15 to 30 minutes, depending on your situation.

After the endoscopy, you will be observed for a period of time, generally, less than one hour, while the sedative medication wears off. Some of the medicines commonly used cause some people to temporarily feel tired or have difficulty concentrating. You typically will be instructed not to drive and not to return to work for the balance of the day of the procedure.

The most common discomfort after the examination is a feeling of bloating as a result of the air introduced during the examination. This usually resolves quickly. Some patients also have a mild sore throats. Most patients are able to eat shortly after the examination.

An upper endoscopy takes approximately 10 to 30 minutes.

The medication you receive during the procedure impairs your judgment, perception, and coordination for the rest of the day. Therefore, you will need a responsible adult to escort you from our facility to your home to assure your personal safety.

You should have little or no pain following your procedure. You may have a slight sore throat that can be relieved with warm liquids, and throat lozenges.

A colonoscopy is an exam used to detect changes or abnormalities in the large intestine (colon) and rectum. During a colonoscopy, a long, flexible tube (colonoscope) is inserted into the rectum.

A tiny video camera at the tip of the tube allows the doctor to view the inside of the entire colon. If necessary, polyps or other types of abnormal tissue can be removed through the scope during a colonoscopy. Tissue samples (biopsies) can be taken during a colonoscopy as well.

Investigate intestinal signs and symptoms.
A colonoscopy can help your doctor to explore possible causes of abdominal pain, rectal bleeding, chronic constipation, chronic diarrhea and other intestinal problems.

• Screen for colon cancer.
• Look for polyps.
• Colon

You can have only clear liquids the day before your test. Avoid red liquids, which can be confused with blood during the colonoscopy. Do not eat or drink anything after midnight the night before your test.

For better results, the colon must be clean and free of stool. To do so, you will be given a laxative to drink. This cleans out your colon and gives the doctor a better view during your test. Your doctor will decide which preparation is best for you. Follow instruction to take laxative.

Arrange for a responsible adult to drive you home and stay with you after your test.

You will lie on your side with your knees drawn toward your chest so you are more comfortable.

Your blood pressure, pulse, breathing, and blood oxygen levels will be monitired during the test.

You will receive a medication through IV to help you relax.

The doctor will insert a long tube called a colonoscope into your rectum and move it through your colon. Dr. will fill your colon with air. This will help the doctor get a better view. The air may give you some discomfort or pressure. This feeling is normal and should go away soon after the test.

A colonoscopy typically takes about 20 minutes to an hour.

After the exam, it takes about an hour to begin to recover from the sedative. You'll need someone to take you home because it can take up to a day for the full effects of the sedative to wear off. Don't drive or go back to work for the rest of the day.

If your doctor removed a polyp during your colonoscopy, you may be advised to eat a special diet temporarily.

You may feel bloated or pass gas for a few hours after the exam, as you clear the air from your colon. Walking may help relieve any discomfort.

You may also notice a small amount of blood with your first bowel movement after the exam. Usually this isn't cause for alarm. Consult your doctor if you continue to pass blood or blood clots or if you have persistent abdominal pain or a fever of 100 F (37.8 C) or higher.

No, colonoscopy is usually not painful! Almost all colonoscopies can be performed using "intravenous sedation" in which you are very drowsy, but comfortable and still breathing on your own.

Bloating and distension typically occur for about an hour after the exam until the air is expelled. Serious risks with colonoscopy, however, are very uncommon. One such risk is excessive bleeding, especially with the removal of a large polyp. In rare instances, a tear in the lining of the colon can occur. These complications may require hospitalization and, rarely, surgery. Quite uncommonly a diagnostic error or oversight may occur.

Due to the mild sedation, the patient should not drive or operate machinery following the exam. For this reason, someone should be available to drive the patient home.
