olonoscopy is the endoscopic examination of the large bowel and the distal part of the small bowel with a camera on a flexible
tube passed through the anus. It can provide a visual diagnosis (e.g. ulceration, polyps) and grants the opportunity for biopsy or
removal of suspected colorectal cancer lesions. Complications of colonoscopy are rare. These complications are perforation, bleeding,
anaesthesia related bowel preparation and infection. The rate of infection was found as 1/1.8 million. The risk of infection development
differs depending on gastrointestinal system region in which the endoscopic procedure is performed, and on type of procedure, and
on patient’s underlying disease. The incidence of bacteremia after colonoscopy whether with or without biopsy and polypectomy
varies between 0 and 25%. Bacteremia developing in immuno competent patients during or after colonoscopy is generally transient
or asymptomatic. The incidence of transient bacteremia in flexible endoscopes varies between 0 and 1%. Colonoscopy related
infections are of two forms: 1) Endogenous infection: The spread of patients own microbial flora in gastrointestinal system to other
organs or prosthesis via the bloodstream during colonoscopy. Endoscopic procedures most often result in endogenous infections
(i.e., infections resulting from the patient's own microbial flora), and
E. coli, Klebsiella
spp.,
Enterobacter
spp., and
Enterococci
are
the species most frequently isolated. 2) Exogenous infections: The spread of microorganisms from one patient to other patient by a
contaminated endoscope (opportunistic pathogens such as bacteria, HBV, HCV, fungi, parasites etc.). The important risk factors of
exogenous infections in colonoscopy are the number of microorganisms present inside the endoscope or biofilm production, invasive
procedure which is resulting tissue damage, immuno compromised status of the patients (malignancy, solid organ transplantations,
immunosuppressive treatment, human immunodeficiency virus, etc.) and presence of infectious focus during colonoscopy. Such
infections are preventable with strict adherence to accepted reprocessing guidelines.
