Surgical Treatments for Periodic Fever, Aphthous Stomatitis, Pharyngitis, and Adenitis Syndrome: Systematic Review and Network Meta-analysis.
To compare surgical versus medical treatment approaches for periodic fever, aphthous stomatitis, pharyngitis, and adenitis (PFAPA) syndrome. PubMed, Embase, Web of Science, and Cochrane. We followed the Preferred Reporting Items for Systematic Reviews and Meta-analyses-Network Meta-analyses checklist. Two authors independently reviewed the studies. Inclusion criteria comprised randomized controlled trials and cohort studies. Non-English studies, along with case series and review articles, were excluded. The primary outcome was the incidence of persistent symptoms following surgery, compared to medical treatment. Secondary outcomes included complications. The search identified 693 publications. After applying the inclusion and exclusion criteria, nine studies were included (three randomized controlled trials and six cohort studies), comprising a total of 691 patients (256 [37%] females, mean age: 2.97 years, and interquartile range: 2.3-3.3). Patients were treated with either tonsillectomy (n = 201), intracapsular tonsillectomy (IT, n = 24), or medical treatment (n = 466). Surgery was associated with a higher likelihood of symptom resolution compared to medical treatment (odds ratio [OR]: 11.7, 95% CI: 2.14-63.94). However, heterogeneity was observed across studies (I = 80.8%, P < .01). A sensitivity analysis was performed, including randomized controlled trials. Both tonsillectomy (OR: 34.15, 95% CI: 3.77-308.95) and IT (OR: 21, 95% CI: 1.5-293.25) were associated with a greater likelihood of symptom resolution. The pooled complication rate was 6.6%, with a higher incidence in patients who underwent tonsillectomy versus IT (46/201 vs 0/24, P = .008). The pooled rate of symptom recurrence was 13.6% in patients following tonsillectomy and 37.5% in IT. Surgical management of PFAPA with tonsillectomy was superior to medical treatment. Tonsillectomy resulted in a lower recurrence rate of symptoms compared to IT, with a comparable incidence of complications to existing literature. However, given the limited number of patients in the IT group, these findings should be interpreted with caution, and further randomized studies are warranted.
