ABSTRACT
BACKGROUND: Our study aimed to compare the clinical outcomes and cost-efficiency of antibiotic management versus laparoscopic appendectomy for acute uncomplicated appendicitis (AUA) in children during the COVID-19 pandemic when resources were limited and transmission risks uncertain. METHOD: In this prospective comparative cohort study, we analyzed the data of 139 children diagnosed with AUA meeting the following inclusion criteria: 5-18 years of age, symptoms duration of ≤ 48 h, appendix diameter ≤ 11 mm and no appendicolith. Treatment outcomes between non-operative management group (78/139) and upfront laparoscopic appendectomy group (61/139) were compared. Antibiotic regimes were intravenous ceftriaxone/metronidazole or amoxicillin/clavulanic acid for 48 h, followed by oral antibiotics to complete total 10-days course. RESULTS: 8/78 (10.3%) children had early failure (within 48 h) requiring appendectomy. 17/70 (24.3%) patients experienced late recurrence within mean follow-up time of 16.2 ± 4.7 months. There were no statistical differences in peri-operative complications, negative appendicectomy rate, and incidence of perforation and hospitalization duration between antibiotic and surgical treatment groups. Cost per patient in upfront surgical group was significantly higher ($6208.5 ± 5284.0) than antibiotic group ($3588.6 ± 3829.8; p = 0.001). CONCLUSION: Despite 24.3% risk of recurrence of appendicitis in 16.2 ± 4.7 months, antibiotic therapy for AUA appears to be a safe and cost-effective alternative to upfront appendectomy.
