Because of the health risks of exposing children to radiation, ultrasound is the preferred first choice with CT scan being a legitimate follow-up if the ultrasound is inconclusive. [54] [55] [56] CT scan is more accurate than ultrasound for the diagnosis of appendicitis in adults and adolescents. CT scan has a sensitivity of 94%, specificity of 95%
It is also called appendicolith when it occurs in the appendix and is sometimes concurrent with appendicitis. [1] They can also obstruct diverticula. It can form secondary to fecal impaction. A fecaloma is a more severe form of fecal impaction, and a hardened fecaloma may be considered a giant fecalith. The term is from the Greek líthos=stone. [2]
CT scan has been shown to be more accurate, than ultrasound in detecting acute appendicitis, [9] but with children and pregnant women, ultrasound may be used to limit radiation exposure. [ 8 ] Treatment
Ultrasound scans show "an oval, non-compressible hyperechoic mass with a subtle hypoechoic rim directly under the site of maximum tenderness". [4] Normally, epiploic appendages cannot be seen on CT scan. [4] After cross-sectional imaging and the increased use of abdominal CT for evaluating lower abdominal pain, EA is increasingly diagnosed.
A CT scan or ultrasound of the abdomen and pelvis are the preferred imaging modalities in the evaluate of an acute abdomen. [8] The use of radiocontrast agents with CT scans improve diagnostic accuracy. [2] Some authors advocate for the use of CT angiography with contrast of the abdomen and pelvis as the preferred imaging modality. [2]
Guarding is a characteristic finding in the physical examination for an abruptly painful abdomen (an acute abdomen) with inflammation of the inner abdominal (peritoneal) surface due, for example, to appendicitis or diverticulitis. The tensed muscles of the abdominal wall automatically go into spasm to keep the tender underlying tissues from ...
The AIR score was developed to overcome some of the drawbacks of the Alvarado score, another diagnostic scoring system for identifying appendicitis. [2] The AIR score is one of the two scores (the other being the Adult Appendicitis Score , AAS) recommended by the 2020 World Society of Emergency Surgery clinical practice guidelines for the ...
Abdominal pain, also known as a stomach ache, is a symptom associated with both non-serious and serious medical issues. Since the abdomen contains most of the body's vital organs, it can be an indicator of a wide variety of diseases.
