Gastroscopy is a medical procedure used to examine the interior of the stomach and the esophagus. This procedure is performed using a thin, flexible tube (endoscope) called an endoscope. Gastroscopy is commonly used to diagnose or treat digestive system problems such as stomach ulcers, gastrointestinal bleeding, esophagitis, and stomach cancer.
It is essential to meticulously follow the instructions given by the specialist before the procedure. Following the specialist's recommendations during the preparation stage helps the procedure to be performed more efficiently and safely.
How is a Gastroscopy Performed?
The gastroscopy procedure is performed in an environment where the patient is under sedation or light anesthesia. A thin, flexible tube called an endoscope is guided through the patient's mouth into the esophagus and stomach. During this time, the doctor views the internal surface of the internal organs and evaluates potential problems. After the procedure, the patient can usually return to normal after a short observation period.
What is a Gastroscopy Used For?
Gastroscopy is a medical procedure used to examine the inside of the stomach and esophagus and to diagnose or treat various digestive system problems. The purposes of using a gastroscopy procedure are as follows:
Stomach Ulcers: It is used for the diagnosis and follow-up of gastric ulcers or duodenal ulcers.
Stomach Bleeding: It can be performed to identify problems causing bleeding inside the stomach or in the esophagus.
Reflux Disease: It is used in the diagnosis and monitoring of reflux disease problems such as inflammation of the esophagus (esophagitis) or stomach acid reflux.
Stomach Cancer: It can be an important tool for the early diagnosis of stomach cancer.
Difficulty Swallowing: It can be used to evaluate the condition of patients experiencing difficulty swallowing (dysphagia).
Pain or Discomfort: It may be required for the examination of patients with specific pain or discomfort complaints related to the digestive system.
Treatment: Samples can be taken or therapeutic procedures can be applied during the procedure. For example, interventional treatments such as removing polyps, stopping bleeding, or opening strictures can be performed.
What are the Risks of a Gastroscopy?
The gastroscopy procedure is generally a safe procedure, but it carries certain risks like any medical intervention. Potential risks that may arise during or after the procedure can be as follows:
Infections: There is a risk of infection if the endoscopy instrument or the equipment used during the procedure is infected. Therefore, sterilization and hygiene rules must be strictly followed.
Bleeding: During the application, small cuts or injuries that may damage the internal surface of the stomach or esophagus may occur. In this case, there is a risk of bleeding.
Swallowing Issues: In rare cases, difficulty swallowing (dysphagia) may be experienced due to the air introduced into the esophagus or stomach during the procedure.
Allergic Reactions: Rare allergic reactions to the medications used during the procedure or to the anesthesia may occur.
Low Oxygen Levels: A drop in the patient's oxygen levels during sedation or anesthesia is rarely seen.
Complications: In rare cases, serious complications may occur, such as perforation of the esophagus or stomach. These serious complications may require emergency surgical intervention.
What Should Be Considered After a Gastroscopy?
Some important points that patients should consider after the gastroscopy procedure are as follows:
Observation and Monitoring: After the procedure, patients are usually kept under observation for a period. During this process, it is checked whether consciousness has fully returned and vital signs are normal.
Fluid Intake: Patients who have fasted during the procedure should gradually start fluid intake. Initially, consuming water or liquid foods in small sips may be appropriate.
Eating: After the application, patients can gradually start solid foods in accordance with the diet recommended by the doctor. Light and easily digestible foods should be preferred.
Pain or Discomfort: Mild stomach ache or a feeling of discomfort is normal after the procedure. Pain relievers or medications recommended by the doctor can be used. However, in case of severe or continuous pain, a healthcare professional should be consulted immediately.
Rest: It is important to rest for a while after the procedure and avoid heavy physical activities. Rest is necessary due to the sedation or anesthesia used during the procedure.
Alcohol and Driving: Consuming alcoholic beverages or driving is not recommended after the procedure, as reactions after sedation or anesthesia may be affected.
Doctor Check-ups: It is important to regularly attend the follow-up appointments recommended by the doctor. These check-ups are necessary to monitor post-procedure recovery and receive additional recommendations when needed.
