    Bacteremia, or bacteria in the bloodstream, is rare after gastrointestinal endoscopy. This study found positive blood cultures in 1% of gastroscopy and 4% of coloscopy patients, with no cases after ERCP.

    Area of Science:

    • Gastroenterology
    • Infectious Diseases
    • Medical Microbiology

    Background:

    • Endoscopy of the gastrointestinal tract is a common diagnostic and therapeutic procedure.
    • The risk of bacteremia following invasive procedures is a clinical concern.

    Purpose of the Study:

    • To prospectively investigate the incidence and frequency of bacteremia after various gastrointestinal endoscopic procedures.

    Main Methods:

    • A prospective study design was employed.
    • Blood cultures were obtained from patients undergoing gastroscopy, coloscopy, and endoscopic retrograde cholangiopancreatography (ERCP).
    • Positive blood cultures were analyzed for bacterial identification.

    Main Results:

    • Bacteremia was detected in 1 out of 100 patients (1%) following gastroscopy.

  • Bacteremia was detected in 1 out of 25 patients (4%) following coloscopy.
  • No bacteremia was observed in 25 patients undergoing ERCP.

    • Conclusions:

    • Bacteremia is an infrequent complication of gastroscopy and coloscopy.
    • Anaerobic lactobacilli were the identified organisms in positive blood cultures.
    • ERCP appears to carry no significant risk of bacteremia in this study cohort.
