Study shows antibiotics may be viable treatment option for appendicitis

A new study published in the New England Journal of Medicine found that seven in ten patients who received antibiotics avoided surgery within 90 days, while four in ten with an appendicolith required surgery. Patients treated with antibiotics reported fewer workdays missed and hospital visits compared to those who underwent surgery.
