To the Editor We read with the great interest the systematic review and meta-analysis by de Almeida Leite and colleagues, 1 who suggest that nonoperative management of acute uncomplicated appendicitis (AUA) is comparable with surgery without an increase in major complications, albeit with a longer hospital stay and a cumulative appendicitis recurrence rate of 18%, highlighted by the authors as 2 major limitations of this treatment approach.The efficacy of antibiotic therapy in adults with AUA ranges from 63% to 85%. 2,3 Appendicitis is often a consequence of obstruction by an appendicolith or appendiceal lumen narrowing, which creates a milieu for microbial proliferation. In such a setting, antibiotics alone cannot achieve source control, which may explain the high recurrence rate seen with nonoperative management of AUA.A 5-year follow-up of the Appendicitis Acuta (APPAC) trial 3 showed a 39% probability of late recurrence in patients initially treated with antibiotics. Beyond recurrent appendicitis, there remains the risk of abscess formation and perforation. The notable inconsistency in the studies included in the current systematic review and meta-analysis is also worth highlighting, which undoubtedly impacts the certainty of the findings supporting the adoption of antibiotic therapy. Consequently, the population of patients with AUA that can truly benefit from antibiotics alone may be limited.Endoscopic retrograde appendicitis therapy (ERAT) is a promising noninvasive treatment modality for AUA. 4 The pooled technical and clinical success of ERAT for AUA from 7 studies (298 patients) was as high as 99%, with a 6% (range, 2.9%-9.9%) recurrence rate. This is likely a projection of achieving source control, either by repeated flushing of the appendiceal lumen or by stent deployment. 5 In our experience, recurrent appendicitis had been noted in patients who did not undergo stent placement with ERAT, highlighting the need for standardization of indications for appendiceal stent deployment. 4 Furthermore, ERAT can be extended to perform appendicoscopy, which allows direct visualization of the appendiceal mucosa and carries diagnostic and therapeutic implications.It is pivotal to follow established principles of achieving source control in addition to antibiotic therapy for obstructive pathologies such as appendicitis. ERAT should be considered an efficacious and safe modality while approaching management of AUA as a therapeutic alternative and for diagnostic evaluation of the appendix as part of a noninvasive management strategy. With appropriate patient selection, ERAT can be performed as an outpatient procedure, which should incentivize training and adoption of this approach in the US Western countries.
