Many techniques have been developed to reduce the number of missed lesions during colonoscopy screening. Autofluorescence imaging (AFI) is one of the newly developed image-enhanced endoscopy (IEE) techniques, which functions similar to narrow band imaging (NBI) and flexible spectral imaging color enhancement (FICE), that can improve the detection and characterization of both polypoid and non-polypoid colonic neoplasms by enhancing their macroscopic features. We have previously reported that AFI, when used in combination with a transparent hood mounted on the tip of the endoscope to maintain distance from the colonic mucosa, results in the detection of approximately 1.6 times more colorectal neoplasms than conventional white light (WLI) colonoscopy. We have also revealed that AFI results in a higher flat neoplasm detection rate than WLI. Because the images of colorectal lesions visualized using AFI differ between histological lesion types, AFI also offers the possibility of differentiating neoplastic from non-neoplastic lesions. However, the difference between neoplastic and non-neoplastic lesions in the images generated using AFI relies on the density of the magenta coloring of the image and is therefore somewhat subjective. Recent studies suggest that NBI with magnification may be a superior modality for characterizing the neoplastic status of small colonic polyps. Although further developments are needed, the recent development of IEEs allows us to efficiently detect and differentiate colorectal neoplasms during colonoscopy screening. This article reviews the use of AFI in the diagnosis of colorectal neoplasms and discusses its advantages and limitations. (Intest Res 2012;10:142-151)

Background/Aims: The etiology of superficial non-ampullary duodenal epithelial tumors (SNADETs) remains unclear. Recent studieshave reported conflicting associations between duodenal tumor development and Helicobacter pylori infection or endoscopic gastricmucosal atrophy. As such, the present study aimed to clarify the relationship between SNADETs and H. pylori infection and/or endoscopicgastric mucosal atrophy. Methods: This retrospective case-control study reviewed data from 177 consecutive patients with SNADETs who underwent endoscopicor surgical resection at seven institutions in Japan over a three-year period. The prevalence of endoscopic gastric mucosal atrophyand the status of H. pylori infection were compared in 531 sex- and age-matched controls selected from screening endoscopies attwo of the seven participating institutions. Results: For H. pylori infection, 85 of 177 (48.0%) patients exhibited SNADETs and 112 of 531 (21.1%) control patients were non-infected(p<0.001). Non-atrophic mucosa (C0 to C1) was observed in 96 of 177 (54.2%) patients with SNADETs and 112 of 531 (21.1%)control patients (p<0.001). Conditional logistic regression analysis revealed that non-atrophic gastric mucosa was an independent riskfactor for SNADETs (odds ratio, 5.10; 95% confidence interval, 2.44–8.40; p<0.001). Conclusions: Non-atrophic gastric mucosa, regardless of H. pylori infection status, was a factor independently associated with SNADETs.

E-learning system to improve the endoscopic diagnosis of early gastric cancer

We developed three e-learning systems for endoscopists to acquire the necessary skills to improve the diagnosis of early gastric cancer (EGC) and demonstrated their usefulness using randomized controlled trials. The subjects of the three e-learning systems were “detection”, “characterization”, and “preoperative assessment”. The contents of each e-learning system included “technique”, “knowledge”, and “obtaining experience”. All e-learning systems proved useful for endoscopists to learn how to diagnose EGC. Lecture videos describing “the technique” and “the knowledge” can be beneficial. In addition, repeating 100 self-study cases allows learners to gain “experience” and improve their diagnostic skills further. Web-based e-learning systems have more advantages than other teaching methods because the number of participants is unlimited. Histopathological diagnosis is the gold standard for the diagnosis of gastric cancer. Therefore, we developed a comprehensive diagnostic algorithm to standardize the histopathological diagnosis of gastric cancer. Once we have successfully shown that this algorithm is helpful for the accurate histopathological diagnosis of cancer, we will complete a series of e-learning systems designed to assess EGC accurately.
