Bleeding in the stomach and intestines, edema, dilated blood vessels Gastric antral vascular ectasia ( GAVE ) is an uncommon cause of chronic gastrointestinal bleeding or iron deficiency anemia . [ 1 ] [ 2 ] The condition is associated with dilated small blood vessels in the gastric antrum , which is a distal part of the stomach . [ 1 ]
A tracheo-esophageal puncture (or tracheoesophageal puncture) is a surgically created hole between the trachea (windpipe) and the esophagus (food pipe) in a person who has had a total laryngectomy, a surgery where the larynx (voice box) is removed. The purpose of the puncture is to restore a person’s ability to speak after the vocal cords ...
Portal hypertensive gastropathy can also be treated with endoscopic treatment delivered through a fibre-optic camera into the stomach. Argon plasma coagulation and electrocautery have both been used to stop bleeding from ectatic vessels, and to attempt to obliterate the vessels, but have limited utility if the disease is diffuse.

Esophageal rupture, also known as Boerhaave syndrome, is a rupture of the esophageal wall. Iatrogenic causes account for approximately 56% of esophageal perforations, usually due to medical instrumentation such as an endoscopy or paraesophageal surgery. [1]

The gastric glands are glands in the lining of the stomach that play an essential role in the process of digestion. All of the glands have mucus-secreting foveolar cells (also known as surface mucous cells) that line the stomach and partly line the gastric pits, and mucus-secreting mucous neck cells in the necks of the gastric glands. [1]
It is the innermost layer of the stomach. [5] It is affected by the hormone histamine, which signals it to release hydrochloric acid (HCl). Sub-mucosal layer – This layer consists of different vessels and nerves, ganglion neurons, and adipose tissue. It is the second layer of the stomach and supports the mucosa. [6]
Diagram of the alkaline mucous layer in the stomach with mucosal defense mechanisms. The gastric mucosa is the mucous membrane layer of the stomach, which contains the gastric pits, to which the gastric glands empty. In humans, it is about one mm thick, and its surface is smooth, soft, and velvety.
