NCT06688955

Brief Summary

A joint opinion of the SFED and the SF2H recommends to orient our colonoscopy practices towards the use of bacteriologically controlled water in reusable bottles for colonic irrigation. To date, no study exists to validate the proposed set-up. Our main objective is therefore to evaluate the microbiological safety of the use of bacteriologically controlled water, in particular the absence of retro contamination of the water in the wash bottle by the faecal flora of the patient undergoing colonoscopy, in order to be able to generalise this practice

Outcome Measures

Primary Outcomes (1)

  • Rate of back contamination

    Rate of back contamination after colonoscopy using the EBM procedure. The absence of retro-contamination is defined as the absence of fecal flora (enterobacteria and fecal streptococci) in the wash bottle during the bacteriological analysis of the EBM microbiological samples taken after each colonoscopy
