A perforated ulcer is a condition in which an untreated ulcer has burned through the mucosal wall in a segment of the gastrointestinal tract (e.g., the stomach or colon) allowing gastric contents to leak into the abdominal cavity.
Depending on the amount of the blood loss, symptoms may include shock. Upper gastrointestinal bleeding can be caused by peptic ulcers, gastric erosions, esophageal varices, and rarer causes such as gastric cancer. The initial assessment includes measurement of the blood pressure and heart rate, as well as blood tests to determine the hemoglobin.
The duodenal bulb is the site of duodenal ulcer occurrence. Duodenal ulcers are more common than gastric ulcers and - unlike gastric ulcers - are caused by increased gastric acid secretion. Duodenal ulcers are commonly located anteriorly, and rarely posteriorly. Anterior ulcers can be complicated by perforation, while the posterior ones bleed.
A peptic ulcer is a defect in the inner lining of the stomach or duodenum typically due to excessive stomach acid. Extension of the ulcer through the lining of the digestive tract results in spillage of the stomach or intestinal contents into the abdominal cavity, leading to an acute chemical peritonitis.

The gastroduodenal artery can be the source of a significant gastrointestinal bleed, which may arise as a complication of peptic ulcer disease.Because of its close relationship to the posteromedial wall of the second part of the duodenum, deeply penetrating ulcers or tumours of the duodenum may cause torrential bleeding from the gastroduodenal ‘artery of haemorrhage'.

[1] [7] An ulcer in the stomach is called a gastric ulcer, while one in the first part of the intestines is a duodenal ulcer. [1] The most common symptoms of a duodenal ulcer are waking at night with upper abdominal pain, and upper abdominal pain that improves with eating. [1] With a gastric ulcer, the pain may worsen with eating. [8]
Despite treatment, re-bleeding occurs in about 7–16% of those with upper GI bleeding. [3] In those with esophageal varices, bleeding occurs in about 5–15% a year and if they have bled once, there is a higher risk of further bleeding within six weeks. [13] Testing and treating H. pylori if found can prevent re-bleeding in those with peptic ...
Types of mesenteric ischemia are generally separated into acute and chronic processes, because this helps determine treatment and prognosis. [ 3 ] Bowel obstruction is most often caused by intestinal adhesions , which frequently form after abdominal surgeries, or by chronic infections such as diverticulitis , hepatitis , and inflammatory bowel ...
