MELENDEZ NEGRETTE, Fernando  y  ACOSTA REYES, Jorge. Is ultrasound useful in the diagnosis of acute appendicitis in patients suffering overweight/obesity?. Rev Chil Cir [online]. 2016, vol.68, n.4, pp.333-336. ISSN 0718-4026.

Acute appendicitis is the most frequent cause of surgical acute abdomen. Although the diagnosis is made by clinical signs and symptoms, images play an important role especially in borderline cases or suspected another abdominal pathology. Ultrasound is the first diagnostic tool, although not the gold standard, is widely available in medical centers, it is cheap, has no ionizing radiation and does not require the administration of iodinated contrast media. However, there are technical factors that limit this study: the absence of fasting, marked interposition of bowel loops and the presence of abundant adipose tissue, it attenuates the ultrasound, making the viewing of the appendix is inaccessible for proper diagnosis. Because of this, ultrasound, should not be considered diagnostic as a quick tool first line for diagnosis in patients with overweight and obesity. Tomography, the opposite occurs, in whom an increase in visceral fat content displays the appendix more effectively by the contrast it provides with intestinal adjacent structures.
