Black stomach is a condition that results from acute gastric necrosis. The tarry black colour is produced by the coagulative necrosis of mucosa resulting in intramucosal haemorrhage and acid hematin deposition. This condition was first described in a patient with acid poisoning. [1]
Gastrointestinal perforation is defined by a full-thickness injury to all layers of the gastrointestinal wall, resulting in a hole in the hollow GI tract (esophagus, stomach, small intestine, or large intestine). A hole can occur due to direct mechanical injury or progressive damage to the bowel wall due to various disease states.
However, not all stomach diseases are labeled with the word "gastropathy"; examples include peptic ulcer disease, gastroparesis, and dyspepsia. Many stomach diseases are associated with infections. In the past it was widely but incorrectly believed that the highly acidic environment of the stomach would keep the stomach immune from infection.
The stomach is a distensible organ and can normally expand to hold about one litre of food. [22] This expansion is enabled by a series of gastric folds in the inner walls of the stomach. The stomach of a newborn baby will only be able to expand to retain about 30 ml.
Helicobacter pylori colonizes the stomach for decades in most people, and induces chronic gastritis, a long-lasting inflammation of the stomach. In most cases symptoms are never experienced but about 10–20% of those infected will ultimately develop gastric and duodenal ulcers, and have a possible 1–2% lifetime risk of gastric cancer.
The abdominal cavity contains most organs of the digestive system, including the stomach, the small intestine, and the colon with its attached appendix.Other digestive organs are known as the accessory digestive organs and include the liver, its attached gallbladder, and the pancreas, and these communicate with the rest of the system via various ducts.

The human stomach has receptors responsive to sodium glutamate [38] and this information is passed to the lateral hypothalamus and limbic system in the brain as a palatability signal through the vagus nerve. [39] The stomach can also sense, independently of tongue and oral taste receptors, glucose, [40] carbohydrates, [41] proteins, [41] and ...
