Malignancy
NO
To evaluate the efficacy of the non-extension sign in assessing the optical diagnosis of colorectal epitherial neoplasm.
Efficacy
The sensitivity, specificity, positive predictive value, negative predictive value, and accuracy of each modality in diagnosing SM-deep cancer in adenoma and early colorectal caner with non-extension sign as an index for the diagnosis of SM-deep cancer.
1.Comparing the accuracy of conventional endoscopy using non-extension sign, magnifying narrow-band imaging, and magnifying chromoendoscopy for optical diagnosis.
2.Others, evaluate all the various result.
Observational
20 | years-old | <= |
Not applicable |
Male and Female
1. Patients performed endoscopic or surgical resection for colorectal epithelial neoplasm (adenoma and early colorectal cancer)
2. ECOG-performance status is 0 or 1 point.
3. Over 20 years old
4. Written informed consent
1. Pedunculated-type lesion
2. Serrated lesion
3. Lesions that are difficult to assess because observation conditions are poor.
4. Impossible pathological evaluation
5. Cases are inflammatory bowel disease, colitis-associated colorectal cancer, advanced cancer, after colon resection, familial adenomatous polyposis.
6. Patients with serious complication.
7. Patients who were judged inappropriate by their physicians.

non-extension sign;
Indigo carmine is sprayed and the colonic wall is strongly extended by endoscopic insufflation of a large volume of air. The area of intramucosal cancer become flattened and extended. On the other hand, the area of SM-deep cancer can be seen as an elevation of the surrounding mucusa due to localized thickening and hardening.
We observe the lesion from the lesion from the front and oblique or tangential directions. Lesions are assessed as positive for non-extension sign if any of the following 3 findings are seen.
1. Rigidity against a background circular arc
2. Trapezoid elevation
3. Converging mucosal folds
