Gastrointestinal endoscopes cleaned without detergent substance following an automated endoscope washer/disinfector dysfunction.
OBJECTIVE
To report cases of gastrointestinal endoscopies performed with endoscopes that were reprocessed without detergent substance during a period of dysfunction of the automated endoscope reprocessor (AER).


METHODS
A dysfunction of the AER for the cycles requiring detergent substance was reported at the Grenoble University Hospital on March 2005. During this period, 72 patients had potentially been exposed to a contaminated endoscope. A recall procedure was organized and serologic tests (HIV, HCV, HBV) were performed 3 and 6 months after the AER incident.


RESULTS
Within the 72 patients convened, 56 (77.8%) were seen in consultation and accepted the serologic screening. Finally, serologic screening was done for 59 patients (81.9%) and no seroconversion for HIV, HCV, or HBV was observed. The final attrition rate was 13 patients (18.1%).


CONCLUSIONS
No viral infection was transmitted during the AER dysfunction. After this AER incident, the monitoring of the endoscopic procedures and the traceability of the cleaning process were both improved to prevent further incidents.
