Abstract Background Underwater endoscopic mucosal resection (UEMR) is a promising strategy for nonpedunculated colorectal polyp removal. However, the efficacy and safety of the technique for the treatment of ≥ 10-mm colorectal polyps remain unclear. We aimed to comprehensively assess the efficacy and safety of UEMR for polyps sized 10–19 mm and ≥ 20 mm. Methods PubMed, EMBASE, and the Cochrane Library databases were searched for relevant articles from January 2012 to November 2019. Primary outcomes were the rates of adverse events and residual polyps. Secondary outcomes were the complete resection, en bloc resection, and R0 resection rates. Results 18 articles including 1142 polyps from 1093 patients met our inclusion criteria. The overall adverse event and residual polyp rates were slightly lower for UEMR when removing colorectal polyps of 10–19 mm vs. ≥ 20 mm (3.5 % vs. 4.3 % and 1.2 % vs. 2.6 %, respectively). The UEMR-related complete resection rate was slightly higher for colorectal polyps of 10–19 mm vs. ≥ 20 mm (97.9 % vs. 92.0 %). However, the en bloc and R0 resection rates were dramatically higher for UEMR removal of polyps of 10–19 mm vs. ≥ 20 mm (83.4 % vs. 36.1 % and 73.0 % vs. 40.0 %, respectively). In addition, univariate meta-regression revealed that polyp size was an independent predictor for complete resection rate (P = 0.03) and en bloc resection (P = 0.01). Conclusions UEMR was an effective and safe technique for the removal of ≥ 10-mm nonpedunculated colorectal polyps. However, UEMR exhibited low en bloc and R0 resection rates for the treatment of ≥ 20-mm polyps.

<b><i>Introduction:</i></b> Endoscopic mucosal resection for small superficial nonampullary duodenal epithelial tumors is a noninvasive treatment; however, perforations can occur. Bipolar snares can reduce the risk of perforation due to small tissue damage. Currently, only few studies have reported endoscopic mucosal resection for small superficial nonampullary duodenal epithelial tumors using a bipolar snare and the effect of preoperative findings. <b><i>Objective:</i></b> To investigate (1) resectability and adverse events of endoscopic mucosal resection using a bipolar snare for small superficial nonampullary duodenal epithelial tumors and (2) the predictions of piecemeal resection. <b><i>Methods:</i></b> Between 2007 and 2017, 89 patients with 107 lesions underwent endoscopic mucosal resection using a bipolar snare. Among them, 88 lesions of 77 patients were evaluated. The primary outcome was the incidence of en bloc resection and R0 resection and adverse events. Risk factors associated with piecemeal resection, including preoperative lesion findings, were also examined. <b><i>Results:</i></b> The incidence rates of en bloc and R0 resections were 85.2 and 48.9%, respectively. Neither intraoperative or delayed perforations nor procedure-related mortality was noted. The nonlifting sign after submucosal injection was associated with an increase in piecemeal resection (odds ratio: 20.3, 95% confidence interval: 2.53–162; <i>p</i> = 0.005). <b><i>Conclusion:</i></b> Endoscopic resection for small superficial nonampullary duodenal epithelial tumors can cause perforation; however, endoscopic mucosal resection using a bipolar snare can be a safe treatment option as it does not cause perforations. The nonlifting sign after submucosal injection is a predictive factor for piecemeal resection.

Abstract Background and study aims Rectal neuroendocrine tumors grade 1 (NET G1; carcinoid) ≤ 10 mm in diameter often extend into the submucosa, making their complete histological resection difficult using endoscopic techniques. Endoscopic submucosal resection with a ligation device (ESMR-L) and endoscopic submucosal dissection (ESD) are commonly used to overcome these difficulties. We also previously reported that underwater endoscopic mucosal resection (UEMR) could facilitate resection of rectal NET G1. This study aimed to evaluate the safety and efficacy of UEMR for removing rectal NET G1 ≤ 10 mm in diameter. 6 consecutive patients with rectal NET G1 ≤ 10 mm in diameter underwent UEMR at our hospital. The rate of en bloc resection was 100 %, and the rate of R0 resection was 83 %. The median procedure time was 8 min (range 5 – 12 min). No perforations or delayed bleeding occurred in this study. In conclusion, UEMR allows the safe and reliable resection of rectal NET G1 ≤ 10 mm in diameter with comparable results to ESMR-L or ESD, including high en bloc and R0 resection rates with no increase in significant adverse events. A multicenter trial is required to confirm the validity of the present results.
