Abstract
BackgroundInfections 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. ObjectiveWe 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 methodsEpidemiological, clinical, and microbiological data were collected in consecutive NSMBT procedures performed in paediatric patients (<18 years) in our centre (2010–2019). Results113 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. ConclusionsNSMBT 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.
