Endoscopy (upper GI System Endoscopy) operation is examination procedure of various parts of digestive channel with the help of fiber optical cables and this has been a very useful diagnosis method in the service of the human for approximately 40 years. Thanks to this procedure, early diagnosis of diseases of the stomach and intestines can be performed and treatments can be implemented on the same session with interventional procedures.
In endoscopy technology, diagnosis of early lesions that are the pioneer of cancer on the stomach and intestine wall has become more likely thanks to advancement and innovations recorded in image sharpness. Lesions detected in this way can be removed with again endoscopic methods and an important contribution has been made to the patient's life. Such lesions can also be removed in this way with combustion treatment methods such as argon plasma laser applied with again endoscopy.
Endoscopy examination of esophagus, stomach and duodenum by directly looking inside the body. This examination can be performed when deemed necessary by the doctor in several cases such as difficulty in swallowing, reflux disease, stomach and abdominal pain, nausea, vomiting, anemia, bleeding in digestive system, B12 vitamin deficiency.
All vital signs of the patient are followed up before, during and after the endoscopy procedure. Examination is conducted by using tipped light, thin (10-12 mm diameter) tubular flexible device called "endoscope". Prior to procedure, the said area is anesthetized by applying a local anesthetic drug with the help of a spray to the throat of the patient. In this way, faucial reflex is repressed and swallowing of the device is facilitated. The patient is lied on his/her left side. During the procedure, some sedatives are administered intravenously to patients for them not to feel any pain or discomfort and any excitement. Through this examination, esophagus, stomach and duodenum are examined in detail extremely precisely. Air is supplied to the stomach during the procedure and in this way, all folds of the stomach can be visible. For this reason, there can be a feeling of swelling during the procedure.
If there is cancer, erosion or ulcer shaped wounds in esophagus, stomach or duodenum cancer when he screams or duodenum during endoscopic examination, these can be directly monitored. Besides, in terms of esophageal reflux disease (esophagitis), whether there is a damage in esophagus or cavity in stomach valve or gastric hernia can be precisely monitored. Reason of bleeding and severity of bleeding can be understood in stomach bleeding thanks to endoscopy operation. Evaluation whether the bacteria considered as the fundamental factors facilitating gastritis and ulcer formation in the stomach is "Helicobacter pylori" bacteria or not can be performed with endoscopy.
If abnormal signs are detected in esophagus, stomach or duodenum, these can be diagnosed visually and in some conditions, conducting a biopsy for histopathological diagnosis can be possible. In addition, bleeding lesion can be also intervened in bleeding conditions. Operations such as drug injection, burning the vein with the help of electrocautery or covering the wound by using special tools called endoclips can be implemented for the bleeding vein for bleeding control.
Endoscopic treatment lasts for 5-10 minutes. However, the patient is kept under observation by taking him/her rest in resting room until the patient becomes conscious again, understands what is spoken and can walk without aid (approximately 1-1.5 hours). Totally losing effect of the drug administered intravenously generally lasts for 4-5 hours. For this reason, the patients should leave endoscopy unit with a companion after the operation. During this time, thoughtfulness, attention deficit, reflex slowing and drowsiness may occur.
