Acute Appendicitis Management

Preoperative Care

The American College of Surgeons recommends using clinical scoring systems, such as the AIR score or Adult Appendicitis Score, to stratify patients into low, intermediate, or high-risk categories, as these tools accurately exclude appendicitis and identify which patients need imaging 3, 4
The World Journal of Emergency Surgery suggests documenting disease severity using a standardized intra-operative grading system, such as the WSES 2015 or sometime referred to as the AAST EGS grading score, based on clinical, imaging, and operative findings 3, 2
Administer a single preoperative dose of broad-spectrum antibiotics 0-60 minutes before surgical incision for all patients undergoing appendectomy, as recommended by the World Journal of Emergency Surgery 3, 2

The American College of Surgeons recommends performing appendectomy within 24 hours of admission for uncomplicated appendicitis to minimize complications 1, 2
For complicated appendicitis with perforation or abscess, perform surgery within 8 hours when possible, as suggested by the Praxis Medical Insights 1, 5
Use conventional three-port laparoscopic appendectomy rather than single-incision technique, as it results in shorter operative times, less postoperative pain, and lower wound infection rates, according to the Praxis Medical Insights 1, 2

The World Journal of Emergency Surgery recommends discontinuing antibiotics after the single preoperative dose for uncomplicated appendicitis 3, 2
For complicated appendicitis, continue postoperative antibiotics with metronidazole 500 mg every 6 hours plus vancomycin 25-30 mg/kg loading dose, then 15-20 mg/kg every 8 hours, as suggested by the Praxis Medical Insights 5
Do not place abdominal drains following appendectomy for complicated appendicitis in adults or children, as they do not improve outcomes, according to the Praxis Medical Insights 1, 2

When advanced laparoscopic expertise is available, proceed directly with laparoscopic appendectomy for appendiceal abscess or phlegmon, as this approach results in fewer readmissions and additional interventions compared to conservative management, as recommended by the World Journal of Emergency Surgery 3, 2
Reserve interval appendectomy only for patients with recurrent symptoms, as suggested by the World Journal of Emergency Surgery 3
For patients ≥40 years old treated non-operatively, perform colonoscopy and interval contrast-enhanced CT scan to exclude appendiceal neoplasms, which occur in 3-17% of this population, according to the World Journal of Emergency Surgery 3
