“…17,18 Tanaka et al reported that DRI was useful in maintaining clear visibility during colorectal ESD, especially with submucosal fatty tissue. 19 Thus, the usefulness of DRI is expected to be clarified in the near future.…”

Background/Aims: Dual red imaging (DRI) is a new, image-enhanced endoscopy technique. There are few reports about the usefulness of DRI during gastric endoscopic submucosal dissection (ESD). We aimed to examine the usefulness of DRI in endoscopic hemostasis during gastric ESD. Methods:We enrolled a total of 20 consecutive patients who underwent gastric ESD. Five endoscopists compared DRI with white light imaging (WLI) for the visibility of blood vessels and bleeding points while performing endoscopic hemostasis. Results: The visibility of blood vessels was increased in 56% (19/34) of the cases, and the visibility of bleeding points was improved in 55% (11/20) of the cases with the use of DRI compared with the use of WLI. Conclusions: DRI improved the visibility of blood vessels and bleeding points in cases with oozing bleeding, blood pooling around the bleeding points, and multiple bleeding points.

“…Thus, the submucosal fibrous tissue could be identified through the hematoma, and was dissected despite the presence of the hematoma. Another advantage of RDI is that it keeps the endoscopic view clearer during ESD with submucosal fatty tissue [5]. We believe that RDI is useful for dissecting submucosal fibrous tissue in the submu-E-Videos ▶ Fig.…”

“… 8 , 9 The usefulness of various devices and methods that compensate for poor scope operability has been reported. 11 , 12 , 13 , 14 , 15 , 16 , 17 Single‐balloon overtube (SBO) is one such assistive device. We previously reported that SBO can improve poor scope operability during ESD in the proximal colon, 18 and there are other reports on its clinical usefulness.…”

Objectives A single‐balloon overtube (SBO) can improve poor scope operability during colonic endoscopic submucosal dissection (ESD). We aimed to evaluate the clinical usefulness of SBO for ESD in the proximal colon and the predictive factors for cases in which SBO is useful. Methods A total of 88 tumors located in the proximal colon resected by balloon‐assisted ESD (BA‐ESD) using SBO and 461 tumors resected by conventional ESD (C‐ESD) between June 2015 and November 2020 were considered. Seventy‐eight tumors each in the BA‐ESD and C‐ESD groups were matched by propensity score matching. ESD outcomes were compared between the groups, and a decision tree analysis was performed to explore the predictive factors for cases in which SBO is useful. Results There were no significant differences between the groups in the major outcomes such as en bloc resection rate (95% vs. 99%, p = 0.17), R0 resection rate (92% vs. 96%, p = 0.30), mean dissection speed (16 mm 2 /min vs. 16 mm 2 /min, p = 0.53), and intraoperative perforation rate (5% vs. 6%, p = 0.73). Even when considering cases with poor preoperative scope operability, there were no significant differences between the groups. Comparison of tumors ≥40 mm in diameter between the groups confirmed that the intraoperative perforation rate was significantly lower in the BA‐ESD group than in the C‐ESD group (0% vs. 24%, p = 0.0188). Conclusion SBO is useful for ESD of tumors ≥40 mm in diameter in the proximal colon to prevent intraoperative perforation, which usually has a long procedure time.
