“…Novel modalities, including NBI-ME, and minimally invasive endoscopic treatments, including ESD, may have multiple benefits compared with conventional procedures. For example, NBI-ME is able to detect early pharyngeal carcinomas (17), and ESD endoscopists are able to perform curative resection of pharyngeal epithelial carcinomas (18). The collaboration of gastro-endoscopists and physicians in other fields is now an option for overcoming conventional issues.…”

Flexible magnifying endoscopy with narrow band imaging for the diagnosis of uterine cervical tumors: A cooperative study among gastrointestinal endoscopists and gynecologists to explore a novel microvascular classification system

Abstract. Narrow band imaging with magnifying endoscopy (NBI-ME), which is useful for the assessment of micro-vessels, has excellent diagnostic potential for early gastrointestinal epithelial neoplasia. Conventional diagnostic tools for uterine cervical epithelial tumors are still unsatisfactory. An accurate diagnostic tool for uterine cervical epithelial tumors is required to preserve the reproductive ability of young women with uterine cervical tumors. Flexible NBI-ME was performed in patients with cervical squamous cell lesions that required further examinations based on their Pap smear results (cytology ≥ low-grade squamous intraepithelial lesion) at Kagawa University Hospital between April 2014 and April 2015. NBI-ME results concordant with the punch biopsy sites were compared with the histological results. A retrospective review of the NBI-ME images identified abnormal NBI-ME results regarding micro-vascular patterns. All images were categorized as having abnormal features. NBI-ME revealed the following vascular pattern differences of different stage tumors: Dot-like vessels without irregular arrangements and high density in cervical intraepithelial neoplasia (CIN) CIN1-CIN2; dot-like vessels with irregular arrangements and high density in CIN3-carcinoma in situ; crawling vessels in minimum invasive cancer; and willow branch vessels and new tumor vessels in invasive cancer. NBI-ME may be an effective diagnostic tool for uterine cervical epithelial tumors, which may lead to the establishment of a novel classification system.

“…NBI refers to an imaging technique for endoscopic diagnostic medical tests, where light of specific blue and green wavelengths is used to enhance the details of certain aspects of the mucosa surface (21). ME-NBI has been revealed to enhance visualization of the micromucosal and microcirculatory structure for a detailed assessment of the early lesions, and may be used to differentiate digestive tract lesions more accurately compared with conventional endoscopy (22,23). However, there are a limited number of studies where ME-NBI has been used in association with SNADT.…”

Abstract. Early superficial non-ampullary duodenal tumors are particularly rare, the clinical manifestations, including typical endoscopic or imaging features, and treatment methods are not well-characterized. The present case report describes a case of an asymptomatic 74-year-old male who presented to the Taizhou People's Hospital (Taizhou, China) for a regular health screening, where a primary superficial non-ampullary duodenal tumor was identified. Upper endoscopy revealed ~1.2 cm lesion in the second portion of the duodenum. Chromoscopy and magnification endoscopy indicated an early cancer characteristic. Subsequent endoscopic submucosal dissection was performed to remove the lesion. Histopathology validated that the lesion was a high-grade intro-epithelial neoplasm without lymph node or blood vessel invasion. IntroductionSuperficial non-ampullary duodenal tumor (SNADT), adenoma or carcinoma, is a rare type of gastrointestinal tract epithelial tumor and can be defined as a lesion limited to the mucosa, and/or submucosa which is not arising from the papilla of Vater (1,2). Typically, the likelihood of developing duodenal adenoma in patients with familial adenomatous polyposis (FAP) is high and this type of adenoma may progress to carcinoma (3). In contrast, sporadic NADT may develop de novo or through the adenoma-carcinoma pathway, as observed in patients with FAP (4). The prognosis of patients with advanced stage carcinoma is poor (5). However, if the duodenal tumor is diagnosed at an early stage and the patient undergoes complete resection, using an endoscopic method, the patient may experience a markedly improved outcome. Therefore, early detection and treatment of lesions are required (6).As the incidence of sporadic SNADT is rare, endoscopic markers suggestive of early stage SNADT have not been established. In addition, although endoscopic approaches, including endoscopic mucosa resection (EMR) and endoscopic submucosal dissection (ESD), are minimally invasive, and localized treatments in comparison to conventional surgery, there are a number of high risk complications (including bleeding and perforation) which may occur during the endoscopic resection (ER) (7-9). Therefore, the relatively rare incidence, and the presence of a thin duodenal wall and rich vascularity make it difficult to detect and treat SNADT lesions.The present case report describes an elderly patient presented to the Taizhou People's Hospital (Taizhou, China) for esophagogastroduodenoscopy and was identified to exhibit a superficial lesion (~1.2 cm) in the second portion of the duodenum. Chromoscopy and magnification endoscopy with narrow band imaging (ME-NBI) indicated an early stage lesion. Subsequently, ESD was performed to remove the lesion. Histopathology validated the high-grade intro-epithelial tumor diagnosis with negative margins, and without lymph or blood vessel involvement.

“…There is growing evidence and interest that the detection and resection of early pharyngeal and hypopharyngeal dysplasia and cancers can be achieved with flexible endoscopy under digital chromoendoscopic guidance. 71 If a cancer extends to or arises in the cervical esophagus, laryngopharyngectomy and esophagectomy may be required. A gastric pull-up procedure may be needed.…”
