How endoscope is done

An endoscope helps your doctor look inside your body without surgery. During an endoscopy, you are awake or a little sleepy. A thin, bendy tube with a camera checks places like your stomach or throat. Doctors do more than 50 million endoscopies each year in the U.S. You can feel safe because serious problems are very rare:

Modern flexible endoscopes from top companies make the process smoother and more comfortable for you:

Key Takeaways

• Endoscopy lets doctors look inside your body safely. You do not need surgery for this test. Serious problems almost never happen.
• Getting ready the right way is very important. You must follow rules about not eating and taking medicine. This helps keep you safe and gives clear results.
• You get medicine to help you relax during the test. Most endoscopies last between 7 and 23 minutes. You will recover fast after it is done.
• After the test, listen to your doctor’s care instructions. Tell your doctor right away if you feel pain or see bleeding.
• New endoscopes show very clear pictures. This helps doctors find and treat many health problems better.

Endoscope Preparation

Getting ready for your endoscopy matters a lot. Preparing well helps your doctor see better and keeps you safe. When you follow the steps, the endoscope works well. Good flexible endoscopes, like ones from Endowista, help your doctor see clearly. But you must prepare the right way.

Fasting and Food Rules

You have to follow special eating and drinking rules before your endoscopy. These rules keep your stomach and intestines empty. This helps your doctor look inside your body.

• Seven days before your test, stop taking NSAIDs like Motrin, Advil, and Aleve. If you use aspirin, take only 81mg each day. Talk to your doctor if you use blood thinners or diabetes medicine.
• The day before your test, eat normally until eight hours before your appointment.
• Eight hours before your endoscopy, stop eating solid foods. You can drink clear liquids like water, apple juice, clear broth, or plain tea. Do not drink anything red, orange, or purple.
• Three hours before your test, stop all food and drinks, even water. Make sure someone can take you to and from your appointment.

Tip: If you follow these steps, your doctor can use the endoscope safely and get good results.

Medication and Consent

Some medicines can change your endoscopy. You may need to stop or change some drugs before your test. Always talk to your doctor about your medicines.

Before your endoscopy, you will sign a consent form. This form tells you the risks and benefits of the test. Ask questions if you do not understand something. Giving your consent means you agree to the test and know what will happen. This step protects you and helps your doctor follow the rules.

Endoscopy Procedure Steps

Arrival and Getting Ready

When you get to your endoscopy, you do some steps to get ready. These steps help keep you safe and make sure the test works well.

1. Two weeks before your test, call your Anticoagulant Clinic if you use blood thinners.
2. Three days before, stop taking Vitamin E, fish oil, and any supplements your doctor says.
3. The day before, eat like normal and take your usual medicines unless your doctor says not to.
4. The night before, stop eating and drinking at midnight.
5. On the day of your endoscopy, take your morning medicines at least four hours before your appointment. Do not eat or drink anything for four hours before your test.

When you check in, a nurse will ask you about your health and medicines. You will change into a hospital gown. The nurse will check your blood pressure, heart rate, and oxygen level. You will meet your doctor and can ask any last questions.

Tip: Bring a list of your medicines and allergies to help your care team.

Sedation and Comfort

You might feel nervous before your endoscopy. The care team wants you to feel calm and safe. Most people get a sedative through an IV in their arm. This medicine helps you relax and may make you sleepy. Some people get a spray to numb their throat if the endoscope goes through the mouth.

Nurses give sedation that works well, even for people who are hard to sedate. Most tests finish in about 7 to 23 minutes, depending on the type. Recovery from sedation usually takes about 22 to 30 minutes. Serious problems from sedation almost never happen.

Note: You need someone to drive you home because you may feel sleepy after the test.

Using the Endoscope

Your doctor uses a flexible endoscope to look inside your body. This tool has a tiny camera and a bright light at the tip. The camera sends live pictures to a screen, so your doctor can see your organs clearly.

• High-definition imaging gives your doctor a sharp, clear view.
• Computer-aided detection helps find small or hidden problems.
• Special imaging uses different light to show blood vessels and tissue patterns.
• 4K Ultra-High Definition systems give even better pictures and depth.

Advanced endoscopes, like ones from Endowista, help your doctor see more details and make better choices. These tools can find tiny changes that older devices might miss. The flexible design lets the endoscope move gently through your body, which helps you feel more comfortable.

Biopsy and Treatment

During your endoscopy, your doctor may need to take a small tissue sample, called a biopsy. The endoscope has a channel for tiny tools, like forceps, to collect samples or treat problems.

• Your doctor can remove polyps, stop bleeding, or fix other issues right away.
• Most procedures work 95% to 100% of the time.
• The test is usually short, and recovery is quick.
• Problems are rare, and most people feel fine soon after.

Callout: You may not feel anything when your doctor takes a biopsy or treats a problem.

Endoscope Removal and Aftercare

When the test is done, your doctor gently removes the endoscope. The care team watches you until you are fully awake. You may feel a little sore throat or bloating, but these symptoms go away quickly.

• Do not eat or drink for at least one hour if your throat was numbed.
• Have a driver with you because you may feel sleepy.
• For the first 24 hours, avoid alcohol, driving, and any medicine that makes you drowsy.
• You can eat your normal foods unless your doctor says not to.
• If you have fever, vomiting, or strong pain, call your doctor right away.
• After a colonoscopy, do not do hard exercise for the first day and have someone stay with you.

Advanced endoscopes focus on your safety and comfort. The care team gives you clear instructions for recovery and checks on you if needed. Most people return to normal activities quickly.

Note: Always follow your doctor’s aftercare instructions for the best recovery.

After Endoscopy

Recovery and Monitoring

After your endoscopy, you move to a recovery area. Nurses watch you closely as you wake up. They check your blood pressure, heart rate, and breathing. You may feel sleepy or a little confused at first. Most people stay in recovery for about 30 to 60 minutes.

Hospitals use several steps to keep you safe after your test:

• Nurses and doctors check on you often and write down your progress.
• Leaders walk around to see how patients feel and how staff work.
• Staff review records and look for ways to improve care.
• Teams share what they learn with each other to make care better.
• If they find problems, they work together to fix them.

You can help by telling your nurse if you feel pain, nausea, or anything unusual.

Side Effects

Most people feel fine after an endoscopy. You might have a sore throat, bloating, or mild cramps. These symptoms usually go away in a few hours. Serious problems are rare, but you should know what to watch for.

• About 1.9% of people who have a colonoscopy may have a serious problem.
• For upper endoscopy, only about 1 in 1,000 people have a complication.
• The chance of dying from these tests is very low, between 0.5 and 3 out of 10,000 cases.
• Heart and lung problems cause about half of all major issues, often because of sedation.

Call your doctor right away if you have chest pain, trouble breathing, fever, or heavy bleeding.

Getting Results

Your doctor usually talks to you about what they saw with the endoscope soon after the test. If your doctor took a biopsy, you may need to wait a few weeks for those results.

Patients typically receive immediate feedback from the endoscopist after the procedure. However, if a biopsy is taken, the results may take a few weeks.

Doctors use different ways to share your results. Here is a table that shows the most common methods:

If your results are normal, your doctor may tell you right away. If you had sedation or if there is something unusual, your doctor may call you later or send a written report. Always ask your care team when and how you will get your results.

Common Questions and Concerns

Many people have questions before their endoscopy. You might wonder what will happen, how to get ready, or what to expect after the test. Here are some of the most common questions patients ask:

• What is upper endoscopy?
• Why is upper endoscopy done?
• How do I prepare?
• What happens during the procedure?
• What happens after the procedure?

Is It Painful?

You may worry about pain during your endoscopy. Most people feel only mild discomfort. Newer tools, like the ultrathin endoscope, make the test easier for you. In recent studies, 66.9% of patients said they had a pain score of 5 or higher during older exams. When doctors used the ultrathin type, the median pain score dropped from 7 to 3. Over 91% of patients felt less pain than before. Almost all patients—97%—said they would do the test again with the ultrathin tool. You may feel pressure or a tickle, but most people do not feel strong pain.

Tip: Tell your nurse if you feel uncomfortable. They can help you relax or adjust the test.

Risks and Safety

Endoscopy is very safe, but every medical test has some risks. Hospitals and clinics work hard to keep you safe. They use several steps to lower risks:

1. Staff keep a detailed list of all their scopes.
2. They check and record any risks for each scope.
3. Teams review safety guidelines from expert groups.
4. They use special plans to make scopes safer.

Hospitals train staff to clean and check every endoscope carefully. They use tracking software to make sure each tool is ready and safe for you. Nurses and doctors follow strict rules to prevent infection and other problems.

Note: If you have questions about safety, ask your care team. They want you to feel safe and informed.

Procedure Time

You may wonder how long the test will take. Most endoscopies last between 7 and 23 minutes. You will spend extra time getting ready and waking up after sedation. The whole visit usually takes a few hours. Your doctor will talk to you before and after the test. You can ask questions at any time.

Remember: Your care team wants you to feel comfortable and know what to expect.

You have learned the main parts of an endoscopy. These are getting ready, having the test, and recovering. Modern flexible endoscopes help keep you safe and comfortable. New disposable endoscopes can make you feel better and help you heal faster. After your test, listen to your care team’s advice:

• Stay in the recovery area until you are fully awake.
• You might have mild bloating or a sore throat.
• Always follow the aftercare steps your doctor gives you.
• Tell your doctor if you have strong pain or bleeding.
• Go to your follow-up visits to talk about your results.

Endoscope technology keeps getting better and helps patients more each year.
