Abstract

Patients with complicated appendicitis have an increased risk for postoperative infections. Potential risk factors for postoperative infections through a meta-analysis and retrospective chart review are discussed. A meta-analysis consisting of 35 studies analyzing complicated appendicitis treated with an appendectomy noting at least 1 postoperative infection was performed. A retrospective review was then conducted in patients diagnosed with complicated appendicitis after appendectomy. Of 5326 patients in total, 15.4% developed postoperative infections. Laparoscopic surgery and perioperative hyperoxygenation were found to be protective factors for the development of infection. Retrospectively, 53.2% of patients presented with complicated appendicitis. Patients with complicated appendicitis were more likely to be older in age and have an increased length of stay. Patient demographics, operative time, and comorbid status had no effect on postoperative infection or readmission rate. Physicians should strongly consider minimally invasive techniques to treat all cases of complicated appendicitis irrespective of comorbidities, age, sex, or body mass index.
