Two-stage optical system for colorectal polyp assessement.

Miroslaw Szura, PhD, Krzysztof Bucki, PhD, Artur Pasternak, PhD, Andrzej Matyja, PhD, Jan Kulig, PhD. Jagiellonian University.

Macroscopic evaluation of the degree of invasion of colorectal polyps allows to choose the most adequate method of endoscopic treatment. Narrow Band Imaging is a new image enhancement system employing optic digital methods to enhance images of blood vessels on mucosal surfaces, allowing improved visualization of mucosal surface structures. However, the superiority of such an imaging over a standard one has not been reported until now.

The aim of this study is to determine if two-stage optical system in new generation of endoscopes will increase diagnostic accuracy in colorectal polyp typing.
Materials and methods:

The study comprised 270 patients, in which 386 colorectal polyps were diagnosed and removed. Polyps were assessed in white light and NBI with use of one and two-stage optical system respectively. Polyps were classified according to pit pattern scheme developed by Kudo and subsequently verified histopathologically. Evaluation was performed during colonoscopic examination as well as retrospectively on the basis of recorded images by 3 experienced endoscopists.ClinicalTrials.gov number, NCT01688557

Results:
There was no difference in the evaluation of polyps regarding the group of non-neoplastic polyps (Kudo I and II). The diagnostic accuracy was 91.6% with application of near focus function vs 89.7% with use of a standard optical system. The diagnostic accuracy of non-invasive adenomas has also risen (Kudo IIIL, IIIS, IV) (91.5% vs 87.2) P<0,05. The same observation concerned invasive lesions (Kudo V) (94.1% vs 91.7%). There were no differences in the evaluation of polyps during colonoscopy in comparison to the retrospective group.

Conclusions:
Two-stage optical system with electronic colorization of the mucosa (NBI) increases diagnostic accuracy for the differentiation of neoplastic colorectal polyps. Preliminary evaluation of a polyp type and character remains the same precise during endoscopic examination as in retrospective analysis.

Respuesta de SAGES al Estudio NordICC sobre el beneficio de las colonoscopias de detección

SAGES desea aclarar los resultados del estudio NordICC y colocarlos en contexto de los esfuerzos de varias agencias nacionales para reducir el riesgo de cáncer colorrectal – la segunda causa de muerte por cáncer más frecuente en los Estados Unidos-, mediante la promoción de la detección y tratamiento oportuno de las lesiones.

SAGES Response to NordICC Study Regarding Benefit of Screening Colonoscopies

The NordICC Study recently published in The New England Journal of Medicine and widely reported on by media outlets has raised questions regarding the benefit of screening colonoscopy in lowering the risk of colorectal cancer and cancer-related deaths among otherwise healthy and symptom-free men and women aged 55 to 64. Provocative headlines and commentaries have […]
