Endoscope control heads can become contaminated during procedures like gastroduodenoscopy and colonoscopy. A simple disinfection method using detergent, alcohol, and chlorhexidine effectively cleans these potential sources of cross-infection.
Area of Science:
- Gastroenterology
- Infection Control
- Medical Device Disinfection
Background:
- Endoscopic procedures like gastroduodenoscopy and colonoscopy are essential diagnostic tools.
- Contamination of medical equipment, particularly endoscopes, poses a significant risk for healthcare-associated infections.
- The control head of endoscopes is a frequently handled component, raising concerns about its potential role in pathogen transmission.
Purpose of the Study:
- To determine the incidence of contamination on endoscope control heads after gastroduodenoscopy and colonoscopy.
- To evaluate the effectiveness of a straightforward disinfection protocol for endoscope control heads.
Main Methods:
- Assessed contamination rates of endoscope control heads during 17 gastroduodenoscopy and colonoscopy procedures.
- Artificially contaminated control heads were subjected to a disinfection process involving scrubbing with detergent and wiping with 70% isopropyl alcohol and 2% chlorhexidine swabs.
Main Results:
- Contamination of endoscope control heads was observed in 4 out of the 17 examinations conducted.
- The disinfection technique proved effective in adequately disinfecting heavily contaminated control heads.
Conclusions:
- Endoscope control heads can become contaminated during routine endoscopic examinations.
- The evaluated disinfection method is effective in eliminating contamination from endoscope control heads.
- Endoscope control heads should be considered a potential source of cross-infection and must be included in all cleaning and disinfection protocols.

Cleaning, Sterilization, and Disinfection
Cleaning
The cleaning process usually involves using water with detergents or enzymatic cleaner and removing foreign material from objects and surfaces, including organic material such as body fluids or inorganic material like soil. Cleaning is performed before high-level disinfection and sterilization because foreign materials on the cover of the devices interfere with process...
