BACKGROUND: Infections related to non-surgical manipulation of the biliary tract (NSMBT) are common events despite periprocedural antibiotic prophylaxis (PAP). Since June 2017, our local protocol has indicated a 24-h regimen of intravenous piperacillin-tazobactam for this purpose.
OBJECTIVE: We aimed to describe the incidence and characteristics of NSMBT-related paediatric infections, define risk factors for their development, and analyse adherence to our PAP protocol.
MATERIALS AND METHODS: Epidemiological, clinical, and microbiological data were collected in consecutive NSMBT procedures performed in paediatric patients (<18 years) in our centre (2010-2019).
RESULTS: 113 procedures in 37 patients, median age 4 years (IQR 1-8), were included. Main underlying diseases were biliary atresia (32%) and cancer (14%). Sixty-eight percent had undergone liver transplant and 70% hepaticojejunostomy. In 44 procedures (39%), the intervention was performed during the course of infection and previously prescribed antibiotic treatment was maintained. In the other 69, PAP was specifically indicated for NSMBT; antibiotic adequacy increased from 35% to 100% after June 2017. In total, 32 NSMBT-related infections (28%) occurred, mainly in the first 24h post-procedure (72%); no deaths happened. Causative pathogens were Gram-negative rods (64%), Gram-positive cocci (28%), and Candida spp. (8%). Main related risk factors were hepaticojejunostomy, biliary obstruction, and liver transplant.
CONCLUSIONS: NSMBT in children entails a significant infection risk, even under antibiotic prophylaxis, being hepaticojejunostomy the main risk factor. Infectious complications mainly occurred immediately after the procedure. After establishing a PAP protocol, 100% of interventions received appropriate prophylaxis, decreasing antibiotic exposure time and potentially, the length of hospital stay.
