Acute appendicitis

Last edited: 4/14/2026

Overview

Acute appendicitis is an inflammatory condition of the vermiform appendix, often requiring surgical intervention in the form of appendectomy to prevent complications such as perforation and peritonitis.

Diagnosis

  • Clinical Presentation: Right lower quadrant pain, nausea, vomiting, fever 14.
  • Diagnostic Tests:
  • - Ultrasonography (US): Effective when performed by experienced practitioners; novice accuracy improves rapidly after initial 20 cases 2. - Computed Tomography (CT): High accuracy for severity grading using CT severity index 3.
  • Grading: CT severity index ranges from 0 (normal appendix) to 3 (perforated appendix) 3.
  • Management

  • Surgical Intervention:
  • - Laparoscopic Appendectomy: Preferred technique, associated with shorter hospital stays, less analgesic use, and fewer complications compared to open appendectomy 4.
  • Antibiotics:
  • - Carbapenems: Shorter hospital stay and fewer complications compared to ciprofloxacin/metronidazole in complicated cases 1. - Ciprofloxacin/Metronidazole: Alternative regimen, but may require antibiotic therapy rotation more frequently 1.

    Special Populations

  • Pediatrics: Tele-mentored ultrasonography can aid in accurate diagnosis of acute appendicitis 5.
  • Elderly and Comorbidities: Specific management adjustments not detailed in provided abstracts.
  • Key Recommendations

  • Use Laparoscopic Appendectomy for both simple and complicated acute appendicitis due to better outcomes and safety profile (Evidence: Strong 4).
  • Consider Carbapenems over ciprofloxacin/metronidazole for complicated appendicitis to reduce hospital stay and complications (Evidence: Moderate 1).
  • Utilize CT for Severity Assessment in acute appendicitis to guide management decisions (Evidence: Moderate 3).
  • Implement Tele-Ultrasonography Mentoring for pediatric patients to enhance diagnostic accuracy in emergency settings (Evidence: Moderate 5).
