Association between white opaque substance under magnifying colonoscopy and lipid droplets in colorectal epithelial neoplasms
AIM To examine the association between white opaque substance (WOS) and histologically verified lipid droplets in colorectal epithelial neoplasms. METHODS We reviewed colonoscopy records at our institution from 2014 to 2016 and identified cases of endoscopically or surgically resected colorectal epithelial neoplasms observed by magnifying narrow-band imaging (M-NBI) colonoscopy. Immunohistoch...
متن کاملThe nature of the white opaque substance within colorectal neoplastic epithelium as visualized by magnifying endoscopy with narrow-band imaging
Background and study aims: We previously reported our discovery of a white opaque substance (WOS) that is opaque to endoscopic light inside the epithelium while using magnifying endoscopy (ME) to examine gastric epithelial neoplasia. Histopathologic analysis revealed that the WOS comprises minute lipid droplets (LDs) accumulated within the neoplastic epithelium. In addition, the WOS was found i...
متن کاملSimplified criteria for diagnosing superficial esophageal squamous neoplasms using Narrow Band Imaging magnifying endoscopy
AIM To simplify the diagnostic criteria for superficial esophageal squamous cell carcinoma (SESCC) on Narrow Band Imaging combined with magnifying endoscopy (NBI-ME). METHODS This study was based on the post-hoc analysis of a randomized controlled trial. We performed NBI-ME for 147 patients with present or a history of squamous cell carcinoma in the head and neck, or esophagus between January...
متن کاملUsefulness of magnifying endoscopy for diagnosing tumorous lesions of the colorectum.
The usefulness of magnifying endoscopy was assessed by examining the extent to which a magnifying endoscope can provide images of pits and by analyzing the consistency of the pit patterns visualized by magnifying endoscopy with the pit patterns visible under a stereomicroscope. Study materials consisted of 83 cases of tumorous colorectal lesions. Under a magnifying endoscope, pits were visible ...
متن کاملClinical Usefulness of Magnifying Chromoendoscopy and Magnifying Narrow Band Imaging Endoscopy for Predicting the Submucosal Invasion of Early Colorectal Cancers
both clinical and economic standpoints, preopera-tive diagnosis is of overriding importance, as it may result in avoidance of unnecessary treatment. Determination of the depth of invasion of submucosal (SM) colorectal cancer (CRC) prior to endoscopic mucosal resection or surgery with lymph node dissection is important. As a part of this, a thorough en-doscopic examination is considered necessar...
