Any additional procedures are performed at this stage. The air in the stomach is aspirated before removing the endoscope. Still photographs can be made during the procedure and later shown to the patient to help explain any findings. In its most basic use, the endoscope is used to inspect the internal anatomy of the digestive tract.
Endoscopy is essential in ruling out other causes of upper gastrointestinal bleeding and in rare cases; active bleeding can be seen from the duodenal ampulla. Even though endoscopy may be normal, it helps to rule out other causes of upper digestive bleeding (erosive gastritis, peptic ulcers, and oesophageal and gastric fundus varices, etc.).
Most patients with portal hypertensive gastropathy have either a stable or improving course in the appearance of the gastropathy on endoscopy.However, according to retrospective data, roughly one in seven patients with portal hypertensive gastropathy will develop bleeding (either acute or chronic) attributable to the gastropathy.

In the post-hoc analysis of subjects with and without gastric erosion at baseline endoscopy, ... (11.3% vs. 30.2%), erosive gastritis (11.5% vs. 26.3%), and gastritis (17.5% vs. 16.0% ...
There is erosive gastritis, for which the common causes are stress, alcohol, some drugs, such as aspirin and other nonsteroidal anti-inflammatory drugs , and Crohn's disease. And, there is non-erosive gastritis, for which the most common cause is a Helicobacter pylori infection. [15] [1]
The steps of management are similar as in erosive gastritis. [4] Endoscopic means of treating stress ulceration may be ineffective and operation required. [11] It is believed that shunting blood away from the mucosa makes the mucous membrane ischaemic and more susceptible to injury. [4] Treatment of stress ulceration usually begins with prevention.
Depending on the site in the body and type of procedure, an endoscopy may be performed by either a doctor or a surgeon. A patient may be fully conscious or anaesthetised during the procedure. Most often, the term endoscopy is used to refer to an examination of the upper part of the gastrointestinal tract, known as an esophagogastroduodenoscopy. [2]
Sometimes the lesions are found when endoscopy is done for other hernia symptoms than anemia such as heartburn, regurgitation, swallowing difficulty, pain or distention. [9] When a person with iron deficiency anemia is found to have a large hernia and Cameron lesions on endoscopy, this usually explains the blood loss.
