Abstract

PURPOSE: Ceftriaxone has been associated with development of pseudolithiasis. In our institution, it is used for treatment of perforated appendicitis in children. This study evaluated the occurrence of ceftriaxone-related pseudolithiasis in this population.

METHODS: After obtaining IRB approval, we performed a retrospective chart review over 51 months. We included patients undergoing laparoscopic appendectomy for perforated appendicitis. All patients were treated with ceftriaxone post-operatively. Patients without initial or post-treatment gallbladder imaging available for review were excluded.

RESULTS: There were 71 patients who met inclusion criteria with a mean (±SD) age of 10.8 ± 3.8 years. Of these, 14 % (n = 10) developed stones or sludge in the gallbladder. The mean duration of ceftriaxone therapy was 8.7 ± 3.8 days. The average time to post-antibiotic imaging was 11.5 ± 10.3 days from initiation of antibiotics. There was no significant difference in duration of ceftriaxone therapy in the children that developed pseudolithiasis or sludge (10.0 ± 4.9 days) compared to those that did not (8.5 ± 3.6, p = 0.26). One child (10 %) with pseudolithiasis went on to become symptomatic, requiring a laparoscopic cholecystectomy.

CONCLUSIONS: In our experience, ceftriaxone use for perforated appendicitis is associated with a significant incidence of biliary pseudolithiasis, and is unrelated to duration of ceftriaxone therapy.
