Procedure and Risks of Endoscopy | Oncology


What is an endoscopy?

Endoscopy is that the insertion of a long, thin tube directly into the body to seem at an internal organ or tissue in detail. It can also be used to carry out other tasks including imaging and minor surgery. Endoscopes are minimal and may be inserted into openings within the body, like the mouth or anus.

Alternatively, they will be inserted into small incisions, for instance within the knee or abdomen. The surgery is completed through a little incision and is assisted by specialized equipment like an endoscope, called keyhole surgery.

Since modern endoscopy has only a few risks, provides detailed images, and works quickly, it’s proven to be very useful in many areas of drugs. Today, tens of many endoscopies are performed annually. In this article, we’ll describe some sorts of endoscopy, why and the way they’ve performed, the overall procedure, and therefore the possible risks.

Endoscopy may be a non-surgical procedure used to examine an individual’s gastrointestinal system. With a versatile hose connected to an endoscope, light, and camera, your doctor can view images of your gastrointestinal system on a colour television monitor.

During upper endoscopy, the scope easily passes through the mouth and throat into the esophagus, allowing the doctor to look at the upper esophagus, stomach, and little intestine. Similarly, endoscopes are often sent to the massive intestine (colon) through the rectum to look at this area of the intestine. This procedure is named a sigmoidoscopy or colonoscopy, counting on how far the colon has been examined.

The unique sort of endoscopy allows endoscopic retrograde cholangiopancreatography, or ERCP, to image the pancreas, gallbladder, and related structures. ERCP is additionally used for stenting and biopsy. Endoscopic ultrasound or EUS can combine upper endoscopy and ultrasound examinations to get images and knowledge about different parts of the alimentary canal.

Why endoscopy is performed?

Upper endoscopy is used to diagnose conditions that affect the upper part of your digestive tract and sometimes to treat the opening of the esophagus, stomach, and small intestine (duodenum).

Your doctor may recommend an endoscopy procedure to:

  • Investigate the symptoms: Endoscopy can help your doctor identify digestive signs and symptoms such as nausea, vomiting, abdominal pain, difficulty swallowing, and gastrointestinal bleeding.
  • Diagnosis: Your doctor may use endoscopy to gather tissue samples (biopsies) to detect diseases and conditions like anaemia, bleeding, inflammation, diarrhoea, or cancer of the alimentary canal.
  • Treatment: Your doctor may send special tools through the scope to treat problems in your gastrointestinal system, like burning the vessel to prevent bleeding, dilating the narrow esophagus, removing the polyp, or a foreign object.

Sometimes endoscopy is combined with other procedures such as ultrasound. An ultrasound probe can be attached to the endoscope to create unique images of the wall of your esophagus or stomach. Endoscopic ultrasound can help your doctor create images of difficult organs like your pancreas. The new endoscopes use high definition video to provide clear images.

Most endoscopes allow your doctor to use a technology called narrow-band imaging, which uses a special light to help better detect pre-existing conditions like Barrett’s esophagus.

When endoscopy is performed?

Doctors often recommend endoscopy to evaluate:

  • Abdominal pain
  • Ulcers, gastritis, or difficulty swallowing
  • Gastrointestinal bleeding
  • Changes in bowel habits (chronic constipation or diarrhea)
  • Polyps or enlargement in the colon

Also, your doctor may use an endoscope to take a biopsy (removal of tissue) to look for the presence of disease.

Endoscopy can also be used to treat a digestive problem. For example, an endoscope can not only detect active bleeding from an ulcer, it can also send devices that can stop bleeding through the endoscope. In the colon, polyps can be removed with an endoscope to prevent the development of colon cancer.

Also, with ERCP, gallstones that have left the gallbladder and entered the bile duct can often be removed.

Endoscopy procedure

This procedure depends to some extent on the explanation for the endoscopy. Abdominal pain, breathing disorders, stomach ulcers, difficulty swallowing, or gastrointestinal bleeding, for instance, an endoscope is often used to search for a cause.

The diagnosis: Endoscopy is often wont to perform a biopsy to diagnose cancer or other diseases.

Treatment: An endoscope is often wont to directly treat a disease; for instance, endoscopy is often wont to catheterize a bleeding vessel (to heat seal) or to get rid of a polyp. Sometimes endoscopy is combined with another procedure, like an ultrasound. It is often wont to place the ultrasound probe near organs that are difficult to image, like the pancreas. Modern endoscopes are sometimes equipped with sensitive lights that use narrow-band imaging. This sort of imaging uses specific blue and green wavelengths, allowing the physician to more easily identify pre-existing conditions. Often the patient is intoxicated.  and lips when the tube is inserted.

Risk factors

This rarely happens, but problems can arise. In all of the discussions leading up to your approach, your doctors will do their part to address possible risk factors based on your current situation and will take the necessary precautions to prevent problems (to the best of their ability).

Some risk factors:

  • Bleeding: This can occur during a biopsy or the treatment of problems found with any type of endoscopic procedure. Blood vessels are accidentally punctured during the bleeding procedure.
  • Infection: The risk of infection from the endoscope procedure is low, but increases when additional procedures are performed.  Your doctor may also prescribe preventive antibiotics before a procedure if she feels you are at risk for infection during the endoscope.
  • Rupture: Sometimes a tear can occur in the esophagus or another part of the upper digestive tract. A tear in the rectal wall or the colon and small intestine wall can also occur. If this happens, you will need to be hospitalized for treatment.
  • Nerve damage and blood clots
  • Stiffness of the knee, injury or damage to the tendons, cartilage, menisci, nerves, or blood vessels of the knee
  • Low blood oxygen level during bronchoscopy
  • Pneumothorax: Collapsed lungs due to increased pressure on the lungs as air escapes into the lining.
  • Allergic reactions to drugs and narcotics (narcotics): Symptoms include shortness of breath, excessive sweating, low blood pressure, slow heartbeat, or laryngitis.

Signs and symptoms that alert your doctor include fever, chest pain, shortness of breath, difficulty swallowing, severe or persistent abdominal pain, and vomiting (especially if there is blood or coffee-like). Plain), insertion of the scope at the incision site, redness and swelling, and persistent pain in the area of bloody, black, or very dark stools (stools). If you notice any of these changes in your body, it is strongly recommended that you see your doctor as soon as possible.
