title: A single dose of prophylactic antibiotic may be sufficient to prevent postprocedural infection in upper endosonography guided fiducial marker placement.
abstract: OBJECTIVE
  Prophylactic antibiotic after endosonographic ultrasound (EUS) guided fiducial marker placement is common practice to prevent infection. Duration of using prophylaxis antibiotic is unknown. The aim of this paper was to assess whether one time intraprocedural administration of a prophylactic antibiotic is sufficient to prevent infection after EUS guided fiducial marker placement.
  
  
  METHODS
  Retrospective study was performed included all adult patients who underwent EUS guided fiducial markers over 18 month period. Procedure related infection was defined as any infection not directly attributable to any other cause within 30 days of the procedure. The patients followed up with the Gastroenterology clinic in one week and with Radiation Oncology clinic weekly after undergoing EUS guided fiducial marker placement.
  
  
  RESULTS
  A total of 35 upper EUS-guided fiducial markers were placed during 20 procedures on 18 patients. The average age of patients was 59 years. There were 10 females and 8 males.. All patients received one dose of cephalosporin, amoxicillin, clindamycin or levoflocaxin. The fiducial markers were deployed in different organs. None of the patients developed any infections due to the procedure.
  
  
  CONCLUSIONS
  This study suggests that one dose of intravenous antibiotic administered intraprocedurally is sufficient to prevent infection related to upper EUS guided fiducial marker placement.
