Ultrasound may unlock appendicitis treatment options

By Erik L. Ridley, AuntMinnie staff writer
February 2, 2017 -- Ultrasound may be able to differentiate between complicated and uncomplicated appendicitis, potentially helping physicians decide whether to proceed directly to an appendectomy or try antibiotics first, according to research published in the February issue of the Journal of Ultrasound in Medicine.
In a retrospective study of more than 100 patients, researchers from Stanford University found that one ultrasound finding -- the loss of the submucosal layer of the appendix -- produced 100% sensitivity and 92% specificity for complicated appendicitis.
"When ultrasound shows loss of the submucosal layer, complicated appendicitis is likely present and, therefore, surgery is likely to be necessary," senior author Dr. Eric Olcott told AuntMinnie.com. "On the other hand, when ultrasound does not show loss of the submucosal layer, antibiotics-first therapy can be considered.
