Drainage of Appendicular Abscess


An appendicular abscess is the collection of pus that is a result of necrosis of the tissue superimposed with infection in an inflamed appendix. It is a life-threatening complication of acute appendicitis (preoperatively) or appendectomy (postoperatively). The aim of treatment is to drain the abscess along with empiric antibiotics. Percutaneous drainage is performed under ultrasound or CT guidance, using either the Seldinger or trocar technique. When an abscess is present deep in the pelvis region, depending on the specific location of the fluid collection, access is gained via transgluteal, transvaginal, or transrectal approach.
