What are the risks associated with esophageal endoscopy

Introduction

Esophageal endoscopy is a technique to view the inside of your esophagus. It uses an endoscope; a thin, flexible tube with camera and light. It’s used to identify symptoms such as swallowing difficulty, chest pain and acid reflux. Plus, it can also detect complications of digestive diseases, like gastritis and esophagitis.

Endoscopy is mostly safe with few risks. Here we will discuss the potential side effects and complications, so you can make an informed decision about the procedure:

Types of Esophageal Endoscopy

Esophageal Endoscopy is a medical procedure. A thin, flexible tube with a camera at the end is inserted into the esophagus. It is used to diagnose and treat gastrointestinal disorders. But, it also has some risks. The type of endoscopy will determine the risks.

In this article, we’ll focus on the different types of esophageal endoscopy and the risks involved:

Upper GI Endoscopy

Upper gastrointestinal (UGI) endoscopy is a procedure used to examine the inside of the esophagus, stomach and duodenum. It’s done by a gastroenterologist. It can be used to diagnose and treat medical conditions.

A thin tube called an endoscope is put into your mouth, down your throat and into your stomach and duodenum. This lets the doctor see inside your upper digestive system and take tissue samples if needed.

The advantages of UGI endoscopy are: it’s less invasive than surgery, with no incisions or major cutting of tissue. Depending on medical conditions or anxiety levels, some patients don’t need sedation or anesthesia. The procedure can also be used therapeutically, to do treatments without extra surgery.

You should discuss the risks of UGI endoscopy with your doctor before having it done. These may include:

• Bleeding
• Perforation of organs
• Breathing difficulties from sedation/anesthesia
• Chest pain/discomfort
• Aspiration of stomach contents into lungs
• Infection
• Allergic reaction to drugs
• Nausea/vomiting
• Difficulty swallowing
• Termination of pregnancy
• Delayed results

Lower GI Endoscopy

Lower GI endoscopy is a procedure that uses an endoscope. This is a thin, flexible tube with a light and camera. It looks at the lower parts of the gastrointestinal tract. The endoscopy can help discover and deal with illnesses in the intestines such as ulcers, swelling, polyps and cancer.

The main kind of lower GI endoscopy is a colonoscopy. This helps to see and take samples from any issues on the walls of the lower intestines. These areas include the colon, rectum, and appendix.

Other types of endoscopies are sigmoidoscopy, proctosigmoidoscopy, double balloon enteroscope and capsule endoscopic examinations. All of these have risks like infection, bleeding, or perforation. You should talk to your doctor about these risks before you decide to have the procedure.

Risks Associated with Esophageal Endoscopy

Esophageal endoscopy is a common medical practice. Generally safe, there are risks. From slight discomfort to life-threatening complications. Let’s take a peek at these risks:

• Slight discomfort
• Life-threatening complications

Bleeding

Bleeding is a typical danger connected with endoscopy. If the esophageal tissues are injured, light to serious bleeding may happen during or after the procedure. Usually this bleeding ceases on its own. However, if it’s extreme, a blood transfusion or extra procedure may be needed.

Bruising and infection are also rare, but can occur. Before any procedure, speak with your doctor about these potential risks.

Perforation

Esophageal endoscopy is a way to diagnose and treat conditions, such as ulcers or hernias, in the esophagus. Your doctor will insert a thin tube, called an endoscope, to look inside. While generally safe, there are risks like perforation. This happens when the endoscope punctures the tissue in the esophagus. Symptoms include chest pain, difficulty breathing and more. Infection, bleeding and vocal cord paralysis are additional complications. In rare cases, breathing problems can occur from obstruction of airways.

Your doctor may suggest preventative measures before the endoscopy. These could be:

• Giving yourself time to eat and drink;
• Taking antacids;
• Antibiotics; and
• Not smoking 8 hours before the procedure.

It is important to understand risks associated with the procedure so you can make an informed decision. Knowing about risks of esophageal endoscopy helps ensure you make a knowledgeable choice.

Infection

Esophageal endoscopy is usually rare, but there is a risk of infection. All instruments must be carefully sterilized between patient use. If they are not, infections such as bacteria or viruses can occur. Endoscopy centers take extra steps to ensure that all equipment and personnel involved are trained and have the right clothing.

Patients with weakened immune systems due to HIV/AIDS and cancer, or those who have taken certain drugs, like HIV inhibitors or steroids, are more at risk of infection. Before the procedure, these patients should ask their doctor if antibiotics are necessary. Also, many antibiotics cause complications if the patient is taking other medications. It is important that patients talk to their doctor about all medications before the procedure.

Allergic Reactions

Allergic reactions to meds used in an endoscopy are unusual, occurring in less than 1 in 10,000 cases. For example, rashes, itching, hives, swelling, shortness of breath, and difficulty breathing have been reported. If you experience any of these during an endoscopy, inform your doctor ASAP.

If you’ve had a previous allergic reaction to anesthesia, there’s a higher risk of another reaction. So, tell your doc about any prior reactions. Additionally, let them know about any food allergies before the procedure.

Esophageal Strictures

Strictures of the esophagus are a risk from Endoscopic procedures. Scar tissue builds up due to damage from the procedure or a condition such as GERD or Eosinophilic Esophagitis. This causes narrowing in the esophageal wall. Swallowing can be difficult and food can get stuck.

Treatment is often endoscopic dilation. An inflated balloon is used to open up the narrow area. This can be done multiple times if needed. Other long-term solutions may be considered if treatments are unsuccessful over time.

Medication may help symptoms, but only after consulting with a doctor.

Conclusion

At the end of an esophageal endoscopy, people may feel a bloating sensation and a lump in their throat. This normally passes within a couple of hours.

Esophageal endoscopy is safe. But, there are some risks. Bleeding, infection or a hole in the wall of the esophagus or other organs could happen. This is rare, though, and medical help is usually needed right away.

Because of the sedation, people could have vomiting or difficulty swallowing after the exam. This usually goes away soon. If chest pain or difficulty breathing happen, contact your doctor right away.

To reduce risks and make sure the exam is successful, follow your doctor’s instructions before and after the procedure:

• Take any medicines your doctor prescribes.
• Follow any dietary and other instructions your doctor gives you.
• Avoid taking aspirin, ibuprofen, or other blood-thinning medicines for several days before the exam.
