Appendectomy remains the only curative treatment of appendicitis, but management of patients with an appendiceal mass can usually be divided into the following 3 treatment categories: Phlegmon or a small abscess: After IV antibiotic therapy, an interval appendectomy can be performed 4-6 weeks later, Larger well-defined abscess: After percutaneous drainage with IV antibiotics is performed, the patient can be discharged with the catheter in place; interval appendectomy can be performed after the fistula is closed, Multicompartmental abscess: These patients require early surgical drainage, Antibiotic prophylaxis should be administered before every appendectomy, Preoperative antibiotics should be administered in conjunction with the surgical consultant, Broad-spectrum gram-negative and anaerobic coverage is indicated, Cefotetan and cefoxitin seem to be the best choices of antibiotics, In penicillin-allergic patients, carbapenems are a good option, Pregnant patients should receive pregnancy category A or B antibiotics, Antibiotic treatment may be stopped when the patient becomes afebrile and the WBC count normalizes.
