Is non-operative treatment of acute appendicitis possible: A narrative review

Abstract

Introduction: Acute appendicitis (AA) represents the most frequent surgical emergency. Perforation was long considered the ultimate outcome of AA, prompting appendectomy; which remains the standard treatment. New data have clarified the role of the appendix, justifying conservative treatment. This narrative review aims to summarize the evidence regarding the non-operative treatment (NOT) of AA in adults. Methods: The literature search was performed via the PubMed Medline database. Our criteria-based selection resulted in a total of 48 articles for review. Results: Recent trials and meta-analyses have assessed NOT, which support primary antibiotic treatment of uncomplicated AA. Although it has a significant recurrence and failure rate, NOT does not appear to increase the risk of appendicular perforation. Moreover, NOT compared with appendectomy, seems to be associated with less morbidity, lower cost of care and preserved quality of life. Conclusion: First-line NOT seems to be a reasonable approach for the treatment of uncomplicated CT-confirmed AA. Careful patient screening would definitely enhance the success rate.
