Summary: This study aimed to develop a diagnostic score system for sessile serrated lesions (SSLs). The research found that tumor size, mucus cap, and indistinct borders were significant endoscopic features for the diagnosis of SSLs, and serrated polyps with these features should be removed during colonoscopy.

Summary: Endoscopic resection (ER) of large non-pedunculated colorectal polyps Gastric Emptying (GE) 20 mm (LNPCPs) is safe, effective and preferred over surgery. Predicting the histopathology of LNPCPs based on various factors is crucial for choosing the appropriate resection technique. Adjuvant techniques, such as thermal ablation, reduce recurrence rates, and endoscopic surveillance is important for detecting and managing recurrence.

Summary: The Japan Gastroenterological Endoscopy Society published the second edition of the guidelines for colorectal endoscopic submucosal dissection/endoscopic mucosal resection to ensure safe and effective endoscopic treatment. Supplementary guidelines for cold polypectomy were also established.

Summary: This cross-sectional study examined the relationship between common abnormalities of the upper digestive tract and colorectal polyps. It found that gastric polyps, Helicobacter pylori infection, and atrophic gastritis were independent risk factors for colorectal polyps.

Summary: Thermal ablation of the defect margin after endoscopic mucosal resection (EMR-T) has been shown to significantly reduce residual or recurrent adenoma (RRA) at first surveillance colonoscopy. In an international multi-center prospective trial, EMR-T was found to be a simple, inexpensive, and highly effective auxiliary technique for managing large nonpedunculated colorectal polyps.

Summary: Most colorectal cancers originate from adenomatous polyps and sessile serrated lesions. Screening colonoscopy combined with therapeutic polypectomy is an effective approach to decrease colorectal cancer incidence and mortality by detecting and removing these polyps at an early stage. Although the majority of polyps can be detected and removed by routine colonoscopy, complex polyps require advanced endoscopic techniques for management.

Summary: This study presented successful outcomes of colorectal ESD at a US tertiary center, with a lower en bloc resection rate compared to other cohorts, but a demonstrated learning curve. R0 resection, lesion recurrence, and adverse event rates were similar to non-Asian experiences, but less favorable than in Asia. Increased ESD training in the US can help optimize utilization and outcomes.

Summary: This study aimed to determine the impact of different definitions of margin involvement on clinical outcomes in endoscopically removed malignant polyps. The results suggest that a definition based on tumor at the margin or within coagulation artifact at the polyp base is more accurate than a 1-mm clearance.

Summary: Tip-in endoscopic mucosal resection (EMR) is a potential alternative for treating large colorectal sessile polyps of >= 20 mm, showing a high en bloc resection rate in polyps of < 30 mm.

Summary: The virtual scale endoscope (VSE) allows real-time size measurements of colorectal polyps by projecting a virtual scale onto them. In this study, the relative accuracy of VSE compared to visual assessment (VA) was evaluated for measuring simulated polyps of different sizes and morphologies. The results showed that VSE had significantly higher relative accuracies than VA for all size groups larger than 5mm, and for all morphology groups.

Summary: This randomized controlled trial aimed to evaluate the short-term outcomes of underwater endoscopic mucosal resection (UEMR) and endoscopic submucosal dissection (ESD) for 21-30 mm colonic polyps. The results showed that ESD had a significantly higher R0 resection rate compared to UEMR, while the en bloc resection rate was similar between the two techniques. The UEMR group had a significantly shorter treatment time than the ESD group.

Summary: This study conducted a systematic review and meta-analysis to analyze the local recurrence rates (LRRs) of large colonic polyps. The results showed that endoscopic submucosal dissection (ESD) and endoscopic mucosal resection (EMR) with routine margin ablation significantly reduced LRR compared to standard EMR. These techniques should be considered as the standard for endoscopic removal of large colorectal polyps.

Summary: The purpose of this study was to develop a quantitative approach for accurately measuring the size and location of polyps using a combination of electromagnetic tracking sensor and endoscopic images. The results demonstrated the accuracy of this method in determining polyp size and location, with clinically acceptable levels of error.

Summary: This study found that the only factor significantly associated with recurrence in histologically incomplete resection of large colorectal polyps was the number of piecemeal resections, with most recurrences occurring after 12 months post-resection. Therefore, patients with <= 2 piecemeal resections and no findings of suspected submucosal cancer may undergo surveillance colonoscopy after 1-2 years.
