Gastroscopy is the examination of the internal parts of the organs of the upper digestive system (esophagus-stomach and intestine) with a special instrument called gastroscopy. Gastroscope; It is a system with a working channel and a light and image recording camera at the end. Thanks to this working channel, the removal of parts from these diseases, stopping the bleeding and endoscopic surgical procedures (inserting a feeding tube into the stomach, removing cancer-leading polyps, treating early cancers, expanding stenosis, opening stenosis through stenting and stenting balloons) are performed.
Which diseases are used in the treatment and diagnosis of endoscopy?
Abdominal pains, burning and souring in this region
Eating food and stomach contents asleep in mouth
Investigation of swallowing difficulties
Investigation of recurrent hoarseness
Follow-up after gastric surgery
Cancers of the upper digestive system
Screening of these organs if there is a family history of cancer
Investigation of the cause of anemia
Investigation of the cause of bleeding in case of bleeding from the mouth
Ulcers of the duodenum and stomach
Inflammation of the gastric mucosa
Diagnosis of stomach bacteria
Treatment of early gastric cancers
Removal of cancer precursor polyps
Removal of foreign bodies escaping from the esophagus and stomach
Dilatation of the esophagus, gastric outlet stenosis, and stents (expandable metal stent)
Stopping ulcer bleeding
Slimming balloon placement
Which preparations should be performed for patients who need to undergo gastroscopy?
A fasting period of 6-8 hours is sufficient before endoscopy. The endoscopist must have knowledge of the patient's complaints before the procedure. The physician should be informed about the blood thinners of the patients who will be considered for serious endoscopic intervention. Gastroscopy is performed by washing the stomach before the procedure in patients with closed stomach and severe bleeding.
How is Endoscopy performed?
Detailed information is given about the procedure, risks and complications. Consent of patients and their relatives is obtained. Before the procedure, the patient who has an open vascular access is able to perform the procedure easily, and the vomiting and secretions do not escape to the airway. Blood oxygen level is continuously measured from the fingertip of the patient and oxygen support is provided if necessary. If the patient's dentures are removed. The endoscope is advanced through the mouthpiece placed in the mouth and the procedure is started. After the procedure, if necessary, drugs are given to enable the patient to wake up. The patient and their relatives who are rested for 15-20 minutes are explained with the result of the procedure.
Can a definitive diagnosis be made by gastroscopy alone?
Gastroscopy can detect the visible diseases of the mucosal surfaces of the organs of the digestive system (the innermost surface of the digestive system). Histopathological examination of the removed parts and polyps is one of the most important steps in the diagnosis. Further investigations are performed to investigate how much these diseases involve the digestive tract and how they spread out of the digestive tract.
Who Can't Have Endoscopy?
Gastroscopy is not performed on patients who completely refuse this procedure. The patient is unconscious and connected to the breathing apparatus does not affect this procedure. We are able to attach endoscopic feeding tubes to patients who cannot be fed for a long time. In order to perform endoscopy, the pathway of the digestive system must be clear. Patients with obstructed digestive tract can also be operated by expanding the narrowed and closed intestine parts with an endoscope or by opening narrow parts with tubes called stents.
What complications (unwanted side effects) can occur in patients undergoing gastroscopy?
Some drugs are given to patients who have undergone endoscopy before and during the procedure. You may develop an allergic reaction to these drugs. Therefore, patients with allergy risk should indicate this condition. In the endoscopy unit of our hospital, necessary measures are taken to prevent such situations, and endoscopy can be performed with the anesthesia team if necessary. Although short-term swallowing difficulty and abdominal distention may sometimes occur after gastroscopy, these complications are very rare and temporary. Bleeding (oral or rectal bleeding) is a very rare condition after gastroscopy. It usually occurs after removal of formations called polyps. Perforation of the esophagus or stomach during the procedure is very rare but the most serious complication.
In which situations should gastroscopy be repeated?
In some cases it may be necessary to repeat the gastroscopy procedure. The frequency of the procedure should be decided after the initial diagnosis of the disease or according to the histopathological examination results. However, it may be necessary to repeat the gastroscopic procedure in the following cases;
In the treatment of drug-treated stomach and duodenal ulcer
Follow-up of stomach polyps
Family history of gastric cancer
In patients with atrophic gastritis and Barret's esophagus at risk of developing cancer
Recurrence of patient complaints despite medical treatment
Follow-up of operated esophageal and gastric cancers
