A gastroscopy is a very safe procedure and the risks of serious complications are small.
If it'sused to diagnose a condition,ithas less than a 1 in 1,000 chance of causing complications.
A gastroscopy used to treat a condition is more invasive and has a higher risk of complications. However,the riskis still relatively small, at around 1 in 100.
Some of the possible complications of agastroscopyinclude:
These are described below.
Sedation is usually safe, but it can occasionally cause problems, such as:
Very rarely, complications from sedation canresultina stroke or heart attack .
Sometimes, during a gastroscopy, the endoscope can accidentally damage a blood vessel, causing it to bleed. However,significant bleeding is very rare.
Signs of bleeding can include vomiting blood and passing black or "tar-like" stools.
The site of the bleeding can usually be repairedduring a further gastroscopy. A blood transfusion may also be required to replace lost blood.
During a gastroscopy, there's a very small risk of the endoscope tearing the lining of your oesophagus, stomach or the first section of your small intestine (duodenum). This is known as perforation.
Signs of perforation can include:
If the perforation isn't severe, it can usually be left to heal by itself. You may be given antibiotics to prevent an infection occurring at the site of the tear.Surgery may be needed to repair more serous perforations.
A gastroscopy is a procedure where a thin, flexible tube called an endoscope is used to look inside the oesophagus (gullet), stomach and first part of the small intestine (duodenum).
A gastroscopy can be used to check symptoms or confirm a diagnosis, or it can be used to treat a condition.
