Background and aim: Olympus Corporation released the texture and color enhancement imaging (TXI) technology as a novel image-enhancing endoscopic technique. We investigated the effectiveness of TXI in the imaging of serrated colorectal polyps, including sessile serrated lesions (SSLs). Methods: Serrated colorectal polyps were observed using white light imaging (WLI), TXI, narrow-band imaging (NBI), and chromoendoscopy with and without magnification. Serrated polyps were histologically confirmed. TXI was compared with WLI, NBI, and chromoendoscopy for the visibility of the lesions without magnification and for that of the vessel and surface patterns with magnification. Three expert endoscopists evaluated the visibility scores, which were classified from 1 to 4. Results: Twenty-nine consecutive serrated polyps were evaluated. In the visibility score without magnification, TXI was significantly superior to WLI but inferior to chromoendoscopy in the imaging of serrated polyps and the sub-analysis of SSLs. In the visibility score for vessel patterns with magnification, TXI was significantly superior to WLI and chromoendoscopy in the imaging of serrated polyps and the sub-analysis of SSLs. In the visibility score for surface patterns with magnification, TXI was significantly superior to WLI but inferior to NBI in serrated polyps and in the sub-analysis of SSLs and hyperplastic polyps. Conclusions: TXI provided higher visibility than did WLI for serrated, colorectal polyps, including SSLs.

“…Endoscopic submucosal dissection (ESD) is an effective technique in early rectal tumors [1], achieving high en bloc and complete resection rates [2]. According to the European Society of Gastrointestinal Endoscopy (ESGE) guidelines, this technique should be considered in rectal lesions with high suspicion of limited submucosal invasion that is based on two main criteria of depressed morphology and irregular or nongranular surface pattern, particularly if the lesions are larger than 20 mm [3].…”

Endoscopic submucosal dissection (ESD) is a validated treatment for early rectal tumors, but whether this therapy is efficient or not for rectal tumors extending to the dentate line (RTDL) remains unclear. We performed a systematic review and meta-analysis to assess the effectiveness and safety of ESD in RTDL compared to non-RTDL. A search in PubMed, Scopus and the Cochrane library up to April 2020 was conducted to identify studies that compared ESD in both localizations (RTDL and non-RTDL), reporting at least one main outcome (en bloc, complete resection, recurrence). Secondary outcomes were adverse event occurrence. Five observational studies including 739 patients with a total of 201 RTDL and 538 non-RTDL were considered. The proportion of female sex (66% vs. 36.9%, P < 0.001) and tumor size [mean difference = 7.75, 95% confidence interval (CI): 3.01-12.49, P = 0.001] were higher in the RTDL group. There were no differences in en bloc resection rates between RTDL and non-RTDL groups [odds ratio (OR): 0.95, 95% CI: 0.50-1.79, P = 0.087]. The complete resection rate was significantly higher in the non-RTDL group (OR: 1.72, 95% CI: 1.18-2.53, P = 0.005, I 2 = 0%). However, recurrence rates were comparable (RD: -0.04, 95% CI: -0.07 to 0.00, P = 0.06, I 2 = 0%). Concerning adverse events, there were no differences in terms of perforation (OR: 0.9, 95% CI: 0.26-3.08, P = 0.86, I 2 = 0%) or delayed bleeding (OR: 0.64, 95% CI: 0.17-2.42, P = 0.51, I 2 = 35%). Anal pain rate was 28% (95% CI: 21.4-35.8%). ESD is an effective and safe therapeutic approach for RTDL with comparable recurrence rate to non-RTDL. The lower complete resection rate in RTDL needs to be clarified in studies.
