with a standard-resolution colonoscope for evaluation of rectal aberrant crypt foci.
According to the company, Optivista offers physicians digital and optical-based electronic chromoendoscopy
with new i-SCAN imaging and OE Optical Enhancement technology.
106) However, emerging evidence suggests that, using more advanced technology such as chromoendoscopy
or high-definition white-light colonoscopy, about 90% of dysplasia in IBD is indeed visible.
To increase the accuracy of endoscopic diagnosis, we carried out an additional chromoendoscopy
with methylene blue staining allowing the detection of foci of intestinal metaplasia (IM) of gastric mucosa which were unrecognized by routine endoscopy.
For lesions with poorly defined margins chromoendoscopy
with indigo carmine stain was used.
Endoscopic evaluation with or without chromoendoscopy
and random biopsies can diagnose a subset of patients in the early stages of ESCC, but the invasiveness of these diagnostic procedures and the potential for sampling error with random endoscopic biopsy limit their effectiveness.
In addition, the researchers only employed chromoendoscopy
to increase detection after a suspicious lesion was identified.
With numerous color clinical photographs and other illustrations, they describe the settings and staff, including disinfection and the role of the pediatric endoscopy nurse, equipment, including image resolution and troubleshooting, patient preparation, including pediatric-monitored sedation and anesthesia, postsedation care and specific sedation techniques, diagnostic upper endoscopy techniques including push endoscopy and jejunoscopy, therapeutic upper gastrointestinal endoscopy, pediatric colonoscopy, polypectomy, chromoendoscopy
, and wireless capsule endoscopy for children, including information on pacemaker safety and bowel preparations.
cap-assisted colonoscopy, wide-angle colonoscopy, and bioendoscopic techniques such as chromoendoscopy
The new HD+ technology in combination with virtual chromoendoscopy
therefore considerably enhances our diagnostic and therapeutic endoscopic options"
ACF are invisible during routine colonoscopy yet are well identifiable in chromoendoscopy
using methylene blue or indigo carmine.
A comparison of magnifying chromoendoscopy
versus histopathology of forceps biopsy specimen in the diagnosis of minute flat adenoma of the colon.
