The value of narrow band imaging combined with stroboscopy for the detection of applanate indiscernible early-stage vocal cord cancer

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.

TÓM TẮT Mục tiêu: Đánh giá kết quả ứng dụng nội soi dải ánh sáng hẹp kết hợp nội soi vi phẫu bằng Laser CO2 trong chẩn đoán và điều trị ung thư hạ họng và ung thư thanh quản giai đoạn sớm. Phương pháp nghiên cứu: Nghiên cứu tiến cứu, có can thiệp lâm sàng trên 18 bệnh nhân ung thư hạ họng, ung thư thanh quản ở giai đoạn sớm, được phát hiện tổn thương ác tính bằng nội soi dải ánh sáng hẹp, điều trị phẫu thuật nội soi vi phẫu bằng Laser CO2. Kết quả: Tuổi trung bình mắc bệnh là 63,8 ± 12,6; bệnh nhân có hút thuốc lá chiếm 61,1%; triệu chứng khàn tiếng chiếm 72%, ung thư giai đoạn T1a có tỷ lệ 72,2%; IPCL type V-1 là 72,2%; khả năng kiểm soát bờ rìa là 83,3%, không có tai biến trong phẫu thuật 17/18 trường hợp và di chứng sau phẫu thuật tháng thứ 1 là tăng sinh mô hạt (77,8%), tháng thứ 3 là dính mép trước dây thanh (27,8%). Kết luận: Nội soi dải ánh sáng hẹp có giá trị phát hiện sớm ung thư hạ họng, ung thư thanh quản. Phẫu thuật nội soi vi phẫu bằng Laser CO2 ung thư hạ họng, ung thư thanh quản ở giai đoạn sớm mang lại kết quả tốt, tỷ lệ tai biến và biến chứng sau phẫu thuật thấp, bảo tồn được tối đa chức năng phát âm, hô hấp và nuốt. ABSTRACT UTILITY OF NARROW - BAND IMAGING ENDOSCOPY COMBINED WITH CO2 LASER ENDOSCOPIC MICROSURGERY IN DIAGNOSIS AND TREATMENT OF EARLYSTAGE HYPOPHARYNGEAL AND LARYNGEAL CARCINOMA Objective: To evaluate the results of applying narrow band imaging endoscopy combined with CO2 laser endoscopic microsurgery to diagnose and treat early stage hypopharyngeal and laryngeal carcinoma. Methods: A prospective study was conducted on 18 patients with early stage hypopharyngeal and laryngeal carcinoma. Results: The mean age was 63.8 ± 12.6; smoker was 61.1%, the rate of hoarseness was 72%, T1a tumor stage was 72.2%, IPCL type V-1 was 72,2%, marginal tumor control was 83.3%. There were of 17/18 case with no complication during operation. The rate of extensive granuloma was 77.8% in the first month, and of anterior commissure adhesion was 27.8% in the third month post - surgery. Conclusion: Narrow band imaging endoscopy was a valuable tool in screening for early stage hypopharyngeal and laryngeal carcinoma. CO2 laser endoscopic microsurgery was an effective method. The rate of complication during and after surgery was low. This method restores the maximum function of speech, breathing and swallowing. Keywords: Early - stage pharyngeal cancer, early - stage laryngeal cancer, narrow - band imaging endoscopy, CO2 laser endoscopic microsurgery.
