What is a high digestive endoscopy?

Upper gastrointestinal endoscopy explores the esophagus, the stomach and the duodenum by means of a gastroscope, which is a flexible instrument finished in a lens and a camera, which is introduced across the mouth, allowing to visualize all the upper gastrointestinal tract. In addition, biopsy samples can be taken, and several treatments, such as polypectomy, stent placement, dilation or bleeding therapy,among others can be performed. In our clinic, upper gastrointestinal endoscopy is always performed with the patient sedated, monitored by a medical specialist, allowing to perform a neither annoying nor painful procedure.

An upper gastrointestinal endoscopy is indicated when a doctor wants to rule out the presence of diseases at the esophagus, stomach or duodenum, as well as when biopsy samples for microbiological or patholoic analysis is needed.

Test preparation

  • The patient have to fast (neither food nor liquids) for at least 8 hours before upper gastrointestinal endoscopy.

  • The patient must also report the medication usually taken, as well as diseases, allergies or any other  medical condition.

  • It is mandatory to be accompanied to the Hospital, since after the procedure, the patient is not suitable to do any  dangerous activity such as driving or any other activity with attention needed.
  • Upper gastrointestinal endoscopy is a very safe diagnostic tool. Complications may occur in less than 1 each 1000 diagnostic precedures. The possibility of complications is higher when upper gastrointestinal endoscopy is used for therapeutic procedures, such as dilations, polipectomy of schlerosis.

  • Among these complications we can mention perforation (hardly ever in case of diagnostic endoscopy), bleeding, drug reactions, cardiopulmonar alterations or transmission of infections. Other less frequent complications are dental fractures, bites, jaw luxation or dysphony.

  • In any case, your doctor will inform you with more details, and will clarify all doubts the patient may have.
