Pneumoperitoneum is pneumatosis (abnormal presence of air or other gas) in the peritoneal cavity, a potential space within the abdominal cavity.The most common cause is a perforated abdominal organ, generally from a perforated peptic ulcer, although any part of the bowel may perforate from a benign ulcer, tumor or abdominal trauma.
Based on evidence from people with other health problems crystalloid and colloids are believed to be equivalent for peptic ulcer bleeding. [15] In people with a confirmed peptic ulcer, proton pump inhibitors do not reduce death rates, later bleeding events, or need for surgery. [18] They may decrease signs of bleeding at endoscopy however. [18]
A Cushing ulcer, named after Harvey Cushing, [1] [2] is a gastric ulcer associated with elevated intracranial pressure. It is also called von Rokitansky –Cushing syndrome. [ 2 ] Apart from the stomach , ulcers may also develop in the proximal duodenum and distal esophagus .
Dissolved oxygen levels required by various species in the Chesapeake Bay (US). In aquatic environments, oxygen saturation is a ratio of the concentration of "dissolved oxygen" (DO, O 2), to the maximum amount of oxygen that will dissolve in that water body, at the temperature and pressure which constitute stable equilibrium conditions.
Peptic ulcer disease is when the inner part of the stomach's gastric mucosa (lining of the stomach), the first part of the small intestine, or sometimes the lower esophagus, gets damaged. An ulcer in the stomach is called a gastric ulcer, while one in the first part of the intestines is a duodenal ulcer. [1]
[4] [5] An ulcer in the stomach is called a gastric ulcer, while one in the first part of the intestines is a duodenal ulcer. The most common symptoms of a duodenal ulcer are waking at night with upper abdominal pain, and upper abdominal pain that improves with eating. [4] With a gastric ulcer, the pain may worsen with eating. [6]
Dieulafoy lesions are characterized by a single abnormally large blood vessel beneath the gastrointestinal mucosa that bleeds, [8] in the absence of any ulcer, erosion, or other abnormality in the mucosa. The size of these blood vessels varies from 1–5 mm (more than 10 times the normal diameter of mucosal capillaries).
Pressure ulcers can trigger other ailments, cause considerable suffering, and can be expensive to treat. Some complications include autonomic dysreflexia, bladder distension, bone infection, pyarthrosis, sepsis, amyloidosis, anemia, urethral fistula, gangrene and very rarely malignant transformation (Marjolin's ulcer – secondary carcinomas in chronic wounds).
