Colonoscopy with polypectomy (CWP) involves visually examining the colon using an endoscope and removing any polyps found. A colonoscopy allows the colonoscopist to identify polyps in the colon. Medical indications for CWP include removing polyps that were previously identified, as polyps have unpredictable behavior and could potentially lead to bowel cancer if not removed. The procedure involves cleaning out the colon the night before using a laxative. Then the colonoscopist guides the endoscope through the rectum and colon, visually examining it and removing any polyps found. After the procedure, the endoscope must be thoroughly cleaned and either chemically disinfected or undergo low temperature sterilization before being properly stored.

8. Medical Indications
• Polyps identified at colonoscopy
cause no harm to the client but it’s
behaviour is unpredictable and may
possibly lead to slow progressive
bowel cancer.
• Therefore, it is advisable to remove it
during colonoscopy.

9. Procedure
The night before, the
patient is given laxative
to remove yuckies.
Before the procedure,
the patient is informed
about CWP.

10. Colonoscopy Procedure
Undignified dignified

11. Procedure
Once inside the rectum, the
examiner uses the image
projected on the screen to guide
his/her way inside the colon.

13. Reprocessing of FE
Immediately after the
procedure, wiped
clean using water
and enzymatic
solution.
Insert scope in
suction valve to
aspirate enzymatic
solution and work
through it.

14. Perform Leak Test

15. Manual Cleaning & Rinsing
• Disassembled parts
as far as
practicable.
• Meticulously clean
and brush, etc.
• Flush-rinse after
this process.

16. Drying and LTS
• Drying following
cleaning.
• Chemical Disinfection
or Low Temperature
Sterilisation

17. Storage
