PHARM - Bowel Preps for Colonoscopy Questions
with Correct Answers
(Brief) Colorectal Cancer Correct Answer-*3rd most common* cancer
diagnosed in both men and women in the US.


*2nd leading* cancer *killer*


Lifetime risk: about 1 in 21 (4.7%) (which is down from 1 in 20 (a 5%
risk) from 2015).


This risk is slightly *lower in women* than in men.


Preventable? Correct Answer-*YES!*


*Polyp-related* colorectal cancer can be
prevented!


The disease develops from benign polyps (mushroom-
like growths on the lining of the colon and rectum).


*Removing these polyps* before they become cancerous
may prevent cancer from developing.

,Colorectal cancer can be cured in up to *90%* of people when it is
discovered in its *early stages*


COLONOSCOPY Correct Answer-is the *GOLD STANDARD* for
diagnosis.


Bowel Preparations Correct Answer-


Why are there so many options? Correct Answer-because there is no
gold standard


still haven't found the perfect one


Brief History of Bowel Preps Correct Answer-Early preps used dietary
limitations, cathartics and enemas


Were time consuming (48-72hrs), uncomfortable for patient, and
associated with fluid and electrolyte disturbances


1980: *Polyethylene Glycol* (PEG) was formulated, which heralded the
modern age of bowel cleansing --> quickly became the *gold standard*


Intense salty taste, bad smell of sulfates and large volume (4L) led to
poor patient compliance

, Preps continue to evolve --> no perfect one yet! But a good quality one
is essential!


Quality of Bowel Prep: Why Does It Matter? Correct Answer-Thorough
mechanical preparation of the colon is essential for efficient, safe and
complete endoscopic examination!


Bowel preparation is inadequate in up to 25% of patients undergoing
colonoscopy (US Multi-Society Task Force on Colorectal Cancer
(2013))


Consequences of inadequate prep:


- Increased *difficulty of colonoscopy*




- *Prolonged procedure time*


- *Reduced cecal intubation rates*


- *Repeat procedures and shorter surveillance intervals*


- *Reduced adenoma detection rates*


- Exposure to *higher malpractice risk*
