Inadequacy of manual cleaning for reprocessing single-use, triple-lumen sphinctertomes: simulated-use testing comparing manual with automated cleaning methods.
Despite widespread reuse of single-use sphinctertomes, publications regarding the adequacy of reprocessing are conflicting and the cautery wire channel is seldom evaluated. Our objective was to use thickened artificial test soil containing microorganisms to perform simulated-use tests combined with in-situ and destructive testing to evaluate cleaning efficacy and ethylene oxide sterilization of single-use triple lumen sphinctertomes. ⋯ Only retro-flushing done within 24 hours of use provided adequate cleaning for multi-lumen, single-use sphinctertomes. Our data validate the efficacy of reprocessing sphinctertomes once with SI-Auto retro-flush cleaning followed by 2 hours of ethylene oxide sterilization.
