Sa1695 Usefulness of the Demarcation Line in Magnified Endoscopy-Combined Narrow Band Imaging for Determining the Expanded Area of Early-Stage Differentiated Gastric Carcinoma

When detected early, uterine cervical cancer is one of the most successfully treatable forms of cancer. The diagnostic accuracy of the standard method, the Pap smear test followed by colposcopy, remains unsatisfactory. To improve detection of early-stage cervical cancer, new diagnostic tools for uterine cervical intraepithelial neoplasm (CIN) need to be developed. Magnifying endoscopy with narrow- band imaging (ME-NBI), which allows the visualization of the micro-structure as well as micro-vascularity of the mucosal surface, has excellent diagnostic ability for early gastrointestinal neoplasms. In our previous investigation, ME-NBI was efficacious for diagnosis of CIN. We herein report two notable cases of CIN3 that were diagnosed by ME-NBI that were not detected by colposcopy. These cases illustrate the usefulness of ME-NBI for diagnosis of early-stage uterine cervical neoplasms.

Mucosal Lesions

Background: Head and neck mucosal lesions are difficult to diagnose at early stage; therefore, they usually present at an advance phase. Narrow Band imaging (NBI) first came to use around 2005 and became one of the most used technologies for image enhanced endoscopy.Material and method: In order to identify best method for early detection of mucosal lesion of head and neck, we examined patients with suspected lesions first under white light endoscopy then under NBI endoscopy. Patients under-went biopsy thereafter, and results were compared. Our aim was to evaluate the role of NBI as a screening tool in the early detection of mucosal lesions of head and neck.Result: It was observed that NBI is useful tool in identifying mucosal lesions of head and neck early. 71 patients were included in our study and it was observed that NBI endoscopy shows 100% sensitivity, 96.36% specificity and 97.18% accuracy in identifying benign lesions. It shows 100% sensitivity, 94.74% specificity and 98.59% accuracy in identifying malignant lesions.Conclusion: In our study we came to conclusion that NBI is very promising tool for early screening purposes of mucosal lesions of head and neck which were missed in routine examination.
