ENHANCING EXAMINATION PRECISION
WITH NARROW BAND IMAGING (NBI)

After undergoing an examination of the patient’s digestive system,
the doctor observed a polyp measuring 2.5 centimetres. Dr.
Korn Lertpipopmetha, a gastroenterologist at Sukumvit Hospital,
explained that during the colonoscopy, white light is commonly
used to detect small polyps. However, this light may not offer a clear
view of very small or flat polyps. In the case of Mrs. Phaipattana
and other patients, Sukumvit Hospital utilized a technology called
Narrow Band Imaging (NBI), which involves a new type of light
wave. This technology enhances the visibility of the mucosa and
blood vessels in the colon, facilitating the detection of small or
flat polyps that may be challenging to identify with white light.
In the case of Mrs. Phaipattana, upon the initial examination,
multiple polyps were observed, varying in size. The use of NBI
assisted in identifying which polyps were at risk of developing
into cancer, those that appeared suspicious, and those with low
or minimal risk. This allowed for a targeted approach in deciding
which polyps to remove.
A subsequent examination incorporated NBI technology for
enhanced detection. The colonoscopy with NBI revealed that
the patient had several worrisome polyps, prompting the removal
and comprehensive testing of all polyps. The largest polyp detected DR. KORN LERTPIPOPMETHA
measured approximately 2.5 centimetres, indicating a significant
size.
“In the case of faecal occult blood tests, it is recommended to
undergo the examination annually. Other methods, such as

screening methods, Dr. Korn provides the following information: “Typically, individuals with no family history of colon cancer are
advised to undergo a colonoscopy around the age of 50. However,
in some countries, screening may start at the age of 45 for the
general population. For those at higher risk, such as those with
a family history of colon cancer or polyps, it is recommended to
start colonoscopy screenings as early as 40 years old.”

Colonoscopy is not as scary as you might think. You can prepare
in the morning and go back in the evening. Prompt screening is
crucial, as seen in Khun Phaipattana’s case – although she had no
symptoms, a significant polyp was discovered. Regular screenings
are better than waiting.
