“…DRI is useful in the presence of a spurting hemorrhage from a duodenal ulcer; bleeding point is noted as deep yellow, leading to clear identification of the bleeding point. 4 A retrospective study by Yorita et al 5 showed that DRI improved the visibility of blood vessels and bleeding points, especially in the presence of oozing blood and pooling of blood during gastric ESD. Maehata et al 6 studied the usefulness of DRI in visualizing bleeding points and hemostasis time during ESD.…”

Endoscopy has been widely used in biomedical imaging and integrated with various optical and acoustic imaging modalities. Photoacoustic imaging (PAI), one of the fastest growing biomedical imaging modalities, is a noninvasive and nonionizing method that owns rich optical contrast, deep acoustic penetration depth, multiscale and multiparametric imaging capability. Hence, it is preferred to miniaturize the volume of PAI and develop an emerged endoscopic imaging modality referred to as photoacoustic endoscopy (PAE). It has been developed for more than one decade since the first report of PAE. Unfortunately, until now, there is no mature photoacoustic endoscopic technique recognized in clinic due to various technical limitations. To address this concern, recent development of new scanning mechanisms, adoption of novel optical/acoustic devices, utilization of superior computation methods and exploration of multimodality strategies have significantly promoted the progress of PAE toward clinic. In this review, we comprehensively reviewed recent progresses in single-and multimodality PAE with new physics, mechanisms and strategies to achieve practical devices for potential applicable scenarios including esophageal, gastrointestinal, urogenital and intravascular imaging. We ended this review with challenges and prospects for future development of PAE.

[1,2] Owning to the urgent need of imaging deep-located biological tissues/organs, biomedical endoscopy has been extensively applied in various fundamental and clinical studies.

“…RDI may reduce the stress experienced by endoscopists, allowing them to avoid vessels and treat bleeding quickly and effectively when it occurs. 3,4 Although it has been previously reported that RDI enables a shortened time to achieve hemostasis, 5,6 its usefulness in helping to prevent bleeding during all steps of ESD has yet to be clarified. In this ESD case, we demonstrated the benefits of full-time RDI, which included not only identifying bleeding points for quick and effective hemostasis but also preventing bleeding by avoiding deep vessels.…”

Endoscopic submucosal dissection of early-stage rectal cancer using full-time red dichromatic imaging to minimize and avoid significant bleeding

et al. 2021

Management of bleeding during endoscopic resections (and even more so in endoscopic submucosal dissection [ESD]) is a critical aspect of the procedure. The low rectum has a higher risk of bleeding because of a rich venous plexus; this can increase procedure time compared with the proximal rectum. 1 Red dichromatic imaging (RDI), a novel imageenhanced endoscopy technology, has been reported to improve the visibility of deep vessels and bleeding points compared with white-light imaging (WLI). 2-4 WLI can be switched to RDI instantly with the press of a single button on the endoscope. We present a case of ESD in the low rectum in which RDI was very useful and effective. An 84-year-old man presented with an 18-mm type 0-Is tumor in the low rectum with concomitant internal hemorrhoids. The anal margin of the lesion extended onto the
