Gastroscopy is the useful examination to diagnose Gastro Esophageal Reflux Disease (GERD).

Many people experience acid reflux or heart burn from time to time, as the result of various degrees of hiatus hernia, which is partly associated with either aging or obesity. Some of them develop to actual mucosal injury at the lower esophagus, which can be diagnosed by gastroscopy. Recurrent mucosal injury at the esophagus sometimes results in mucosal degeneration called Barrett’s Esophagus, which is known to be a risk factor for Esophageal cancer.

Gastroscopy is also useful for diagnosing Helicobacter Pylori related gastritis. Since it is the definite risk factor for gastric cancer, it is important to find a various form of precancerous lesion which can frequently be found in H.Pylori related gastritis. H.Pylori related gastritis is also known to be associated with gastric ulcer, duodenal ulcer, and gastric mucosa associated lymphoid tissue (MALT) lymphoma.

An upper endoscopy is a procedure used to visually examine the upper digestive tract using a small camera attached to the end of a long, flexible tube. In this procedure, a gastroenterologist uses an endoscopy to diagnose and sometimes treat conditions that affect the esophagus, stomach, and the beginning of the small intestine (duodenum). Upper endoscopy can be performed in an outpatient surgical center or in a hospital.

A doctor can use an endoscopy to determine the causes of digestive system signs and symptoms, such as nausea, vomiting, abdominal pain, difficulty swallowing, and gastrointestinal bleeding.

The doctor may use endoscopy to collect tissue samples (biopsy) to look for specific diseases and conditions, such as anemia, bleeding, inflammation, diarrhea, or cancers of the digestive system.

Endoscope can also be used in treatment, as the specialist can pass special tools through an endoscope to treat problems in the digestive system, such as widening the narrow esophagus, getting rid of polyps, or removing a foreign body.

Modern endoscopes use an HD video camera to capture clearer images, as well as have a technique called narrow-band imaging (NBI), which uses a special light to help doctors better detect precancerous conditions in the digestive tract.

Although endoscopy is a very safe procedure, scientists report some rare complications. Among these complications is the risk of bleeding after the endoscopy, which increases if the operation involves removing a piece of tissue for testing (biopsy) or treating a digestive problem.

It should be noted that the risk of complications can be reduced by carefully following the instructions of the doctor who is following the case to prepare for the endoscopy, such as fasting and stopping certain medications. The patient must inform his doctor of all medications and dietary supplements that he is taking before the endoscopy. And if he is taking certain blood-thinning medications, the doctor may recommend that he stop taking them in the days leading up to the endoscopy. This is because blood-thinning medications may increase the risk of bleeding if certain procedures are performed during an endoscopy.

The endoscopy usually takes 10 to 15 minutes, depending on the patient’s condition.

When the doctor passes the endoscope down the esophagus, a small camera transmits the images to a video screen in the examination room. The doctor monitors this screen to look for problems within the upper digestive tract. If any anomalies are detected, the images are recorded for use in a subsequent examination.

Gentle air may be pumped into the esophagus to distend the digestive tract. This allows the doctor to more easily examine the folds of the digestive tract. The patient may feel pressure or full from the added air.

The doctor passes special surgical tools through the endoscope to take a tissue sample or remove any tumors and monitors the video screen to guide the tools.

The timing of the results also depends on the case. For example, if a doctor performs an endoscopy to discover an ulcer, the result may be recognized soon after the procedure. If the doctor takes a tissue sample (biopsy), the patient may have to wait several days to get results from the testing laboratory.

The recommendation of endoscopy for medical checkup is also noted. At present, the optimal screening strategy is reported to be every three years. Stomach cancer is likely to develop in a state before detection, with the intervals between examination, which are longer than three years, but screening less frequently than every three years does not seem to be more beneficial.

In the countries where gastric cancer is still prevalent such as Asia, South America, and Middle East as well, Helicobacter Pylori related gastritis is the most important and definite risk factor that is associated with the development of gastric cancer. Therefore, a patient who has a history of H.Pylori infection or has been diagnosed of H.Pylori related gastritis is recommended to be followed up by gastroscopy every 1 to 2 years depending on the state of gastritis, even after H.Pylori is successfully eradicated. In patients who have been diagnosed of no history of H.Pylori infection, a recommended interval of gastroscopy checkup can be extended to every 5 years.



胃内視鏡検査は、ヘリコバクターピロリ関連の胃炎の診断にも役立ちます。これは胃癌の明確な危険因子であるため、H.Pylori関連胃炎によく見られるさまざまな形態の前癌病変を見つけることが重要です。 H.Pyloriは、胃潰瘍、十二指腸潰瘍、および胃粘膜関連リンパ組織(MALT)リンパ腫に関連することも知られています。






内視鏡検査は非常に安全な手順ですが、いくつかのまれな合併症が報告されています。 これらの合併症の中には、内視鏡検査後の出血のリスクがあります。これは、手術が検査(生検)または消化器系の問題の治療のために組織片を取り除くことを伴う場合に増加します。

合併症のリスクは、特定の薬剤の絶食や中止など、医師の指示に注意深く従うことによって減らすことができることがあります。 患者は、内視鏡検査の前に服用しているすべての薬と栄養補助食品を医師に通知する必要があります。 また、特定の抗凝血薬を服用している場合、医師は内視鏡検査に至るまでの数日間は服用を中止することを勧める場合があります。 これは、内視鏡検査中に特定の手順を実行すると、抗凝血薬が出血のリスクを高める可能性があるためです。
