Upper endoscopy (esophagogastroscopy)

Mainly to rule out reflux, hiatal hernias, polyps, gastric, or other alterations before modifying

the stomach and be sure which is the best surgery for the patient,

if something additional needs to be done besides bariatric surgery.

Endoscopy  It is an examination that allows direct visualization of the upper part of the digestive tract (esophagus, stomach and duodenum), using a thin flexible tube.

Gastroscopy has an important therapeutic aspect.

Through the endoscope channel, we can pass a wide variety of instruments, which allows us to act on various activities: dilation of stenotic (narrow) areas, removal of polyps, extraction of foreign bodies, treatment of hemorrhage sources, etc.

Endoscopy is frequently performed in order to evaluate the cause of abdominal discomfort:  pain, nausea, difficulty swallowing, heartburn, burning, etc. in the upper digestive tube

Using this technique, the results can be detected in the early stage.  By removing small samples from the mucosa, which are then studied under a microscope, a distinction can be made between benign and malignant lesions.

In what diseases is this test performed?

  • Stomach cancer

  • Chronic gastritis.

  • Peptic ulcer


What happens after the scan?

After the scan, you should wait a few minutes before trying to eat or drink fluids.  Once the effect has worn off, you can continue your usual diet.

The result of the gastroscopy is known once it is finished.  If biopsies and / or cytology have been taken, it will take several days to have the definitive diagnosis.

Endoscopy has also been used for gastric decompression or for terminal diseases, such as unresectable carcinoma of the antrum, and for postsurgical edema in a jejunum-gastroanastomosis or a pyloroplasty; it has also been used for the reintroduction of bile in patients with external biliary fistula. In pediatric patients, the procedure has been used with excellent results, in children with critical or debilitating illnesses that prevent adequate suction or swallowing.
