Examples of appendicitis in the following topics:
-
- Ultrasonography provides a useful means to detect appendicitis, especially in children.
- The histological findings of appendicitis are neutrophils in the muscularis propria.
- Acute appendicitis is typically managed by surgery to remove the appendix.
- Acute appendicitis has been shown to occur antecedent to cancer in the colon and rectum.
- Several studies offer evidence that a low fiber intake is involved in the pathogenesis of appendicitis.
-
- Peritonitis may be localized or generalized, and may result from infection (often due to rupture of a hollow organ as may occur in abdominal trauma or appendicitis) or from a non-infectious process.
- Examples include perforation of the distal esophagus, of the stomach by a peptic ulcer or gastric carcinoma, of the duodenum, of the remaining intestine by appendicitis, diverticulitis, inflammatory bowel disease (IBD), intestinal infarction, intestinal strangulation, colorectal carcinoma, or of the gallbladder.
- If properly treated, typical cases of surgically correctable peritonitis (e.g., perforated peptic ulcer, appendicitis, and diverticulitis) have a mortality rate of <10% in otherwise healthy patients, which rises to about 40% in the elderly, and/or in those with significant underlying illness, as well as in cases that present late (after 48 hours).
