“…Although no reports on the use of magnifying endoscopy combined with acetic acid application were included in the analysis, the usefulness of this combination has been demonstrated in other studies . When limited to reports from Japan, the diagnostic performances of NBI combined with magnifying observation and acetic acid combined with magnifying observation were also favorite suggesting that the concurrent use of magnifying endoscopy can improve the qualitative diagnosis (cancer/noncancer differential diagnosis) of lesions (Table ).…”

The Japan Gastroenterological Endoscopy Society has developed endoscopic submucosal dissection/endoscopic mucosal resection guidelines. These guidelines present recommendations in response to 18 clinical questions concerning the preoperative diagnosis, indications, resection methods, curability assessment, and surveillance of patients undergoing endoscopic resection for esophageal cancers based on a systematic review of the scientific literature.

“…In recent years, the efficacy of the target biopsies using acetic acid [ 32 , 33 ] or Narrow Band Imaging (NBI) [ 34 , 35 ] has been reported. In addition, several classifications of EAC using magnified NBI have been reported [ 36 – 38 ]. These classifications are very useful in clinical practice.…”

Background. The present study aimed to evaluate the efficacy of linked color imaging (LCI) in diagnosing Barrett’s esophagus (BE) and esophageal adenocarcinoma (EAC). Methods. A total of 112 and 12 consecutive patients with BE and EAC were analyzed. The visibility scores of BE and EAC ranging from 4 (excellent visibility) to 0 (not detectable) were evaluated by three trainees and three experts using white light imaging (WLI), LCI mode, and blue laser imaging bright (BLI-b) mode. In addition, L ∗ a ∗ b ∗ color values and color differences ( Δ E ∗ ) were evaluated using the CIELAB color space system. Results. The visibility score of the BE in LCI mode ( 2.94 ± 1.32 ) was significantly higher than those in WLI ( 2.46 ± 1.48 ) and BLI-b mode ( 2.35 ± 1.46 ) ( p < 0.01 ). The color difference ( Δ E ∗ ) from the adjacent gastric mucosa in LCI mode ( 17.11 ± 8.53 ) was significantly higher than those in other modes ( 12.52 ± 9.37 in WLI and 11.96 ± 6.59 in BLI-b mode, p < 0.01 ). The visibility scores of EAC in LCI mode ( 2.56 ± 1.47 ) and BLI-b mode ( 2.51 ± 1.28 ) were significantly higher than that in WLI ( 1.64 ± 1.46 ) ( p < 0.01 ). The color difference ( Δ E ∗ ) from the adjacent normal Barrett’s mucosa in LCI mode ( 19.96 ± 7.97 ) was significantly higher than that in WLI ( 12.95 ± 11.86 ) ( p = 0.03 ). Conclusion. The present findings suggest that LCI increases the visibility of BE and EAC and contributes to the improvement of the detection of these lesions.

“…Mucosal pattern classifications based on CV chromoendoscopy are considered to be similar to the newly developed magnifying NBI endoscopic classification presented by the Japan Esophageal Society for BE (JES-BE) to diagnose dysplastic Barrett’s lesion easier [ 77 ]. This JES-BE classification also has divided non-dysplastic BE into pit or non-pit type by the character of mucosal pattern.…”

Given that endoscopic findings can be used to predict the potential of neoplastic progression in Barrett’s esophagus (BE) cases, the detection rate of dysplastic Barrett’s lesions may become higher even in laborious endoscopic surveillance because a special attention is consequently paid. However, endoscopic findings for effective detection of the risk of neoplastic progression to esophageal adenocarcinoma (EAC) have not been confirmed, though some typical appearances are suggestive. In the present review, endoscopic findings that can be used predict malignant potential to EAC in BE cases are discussed. Conventional results obtained with white light endoscopy, such as length of BE, presence of esophagitis, ulceration, hiatal hernia, and nodularity, are used as indicators of a higher risk of neoplastic progression. However, there are controversies in some of those findings. Absence of palisade vessels may be also a new candidate predictor, as that reveals degree of intense inflammation and of cyclooxygenase-2 protein expression with accelerated cellular proliferation. Furthermore, an open type of mucosal pattern and enriched stromal blood vessels, which can be observed by image-enhanced endoscopy, including narrow band imaging, have been confirmed as factors useful for prediction of neoplastic progression of BE because they indicate more frequent cyclooxygenase-2 protein expression along with accelerated cellular proliferation. Should the malignant potential of BE be shown predictable by these endoscopic findings, that would simplify methods used for an effective surveillance, because patients requiring careful monitoring would be more easily identified. Development in the near future of a comprehensive scoring system for BE based on clinical factors, biomarkers and endoscopic predictors is required.
