Summary: Traction techniques play an important role in endoscopic submucosal dissection, providing adequate visualization of submucosal tissue and vasculature for safe and efficient operations. These techniques can be categorized into internal and external traction, allowing personalized traction based on the location of the lesion. Mastering these techniques requires structured training and understanding of their advantages and disadvantages. Future research should focus on training pathways and curriculums, as well as the development of new traction modalities.

Summary: This study retrospectively analyzed 15 patients with gastric adenocarcinoma of the fundic gland type (GA-FG) and evaluated the efficacy and safety of endoscopic submucosal dissection (ESD) for GA-FGs. The results showed that ESD is effective and safe for the treatment of early-stage GA-FGs.

Summary: The study found that endoscopic findings of GA-FGM showed specific features under dye-spraying method which were not observed in GA-FG lesions. Magnifying endoscopy revealed that GA-FGM lesions met the diagnostic criteria for cancer, while GA-FG lesions did not, suggesting the potential usefulness of magnifying endoscopy with NBI for diagnosing GA-FGM.

Summary: This study aimed to elucidate the endoscopic causes and characteristics of missed gastric cancers (MGCs) after endoscopic submucosal dissection (ESD) for early gastric cancer (EGC). The results showed that the endoscopic causes of MGCs included perceptual errors, exposure errors, sampling errors, and inadequate preparation. Logistic regression analysis revealed the risk factors for perceptual errors and the sites of exposure errors.

Summary: This study compared the diagnostic performance of standard and M-NBI endoscopy for H. pylori gastritis and precancerous conditions. In 254 patients, M-NBI endoscopy showed slightly higher accuracy for diagnosing H. pylori gastritis and benign conditions compared to standard endoscopy.

Summary: The survey of ESD experts in the US showed that the majority work in university-based, community, or tertiary care hospitals, and most of them received formal supervised hands-on training before performing ESD independently. Many indicated that credentialing requirements should include attending weekend ESD courses, observing live procedures, practicing on explants, and advanced endoscopic training in interventional endoscopy.

Summary: Magnifying and nonmagnifying image-enhanced endoscopy (IEE) show comparable effectiveness in diagnosing gastric intestinal metaplasia (IM). Nonmagnifying IEE demonstrates similar performance as magnifying IEE in evaluating light-blue crest (LBC), white opaque substance (WOS), and endoscopic grading of gastric IM (EGGIM). The presence of high EGGIM score is correlated with gastric cancer (GC) in patients.

Summary: This study compared standard endoscopy and NBI-M in the diagnosis of H. pylori infections, atrophic gastritis, and intestinal metaplasia. Although NBI-M had better sensitivity, the diagnostic accuracy was similar between the modalities. Future studies may help guide endoscopists in choosing the most effective and cost-effective diagnostic modality for difficult cases of H. pylori-related gastritis and precancerous conditions.

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: Gastric adenocarcinoma of fundic gland (chief cell predominant type) is a rare variant characterized by mild nuclear atypia and specific immunohistochemical markers, often coexisting with well-differentiated tubular adenocarcinoma. It presents in the deep mucosal layer and muscularis mucosa, undetectable by endoscopy but discernible in pathology with mild nuclear atypia and special biomarkers.

Summary: Esophageal squamous cell carcinoma (ESCC) requires early detection and treatment for improved survival, but diagnosis can be challenging due to observer variation. Studies have shown significant dysregulation of miRNA expression in superficial ESCC, particularly with miR-21-5p, miR-146b-5p, and miR-210-3p. These miRNAs are associated with ESCC invasion depth and lymphovascular invasion.

Summary: The German ESD registry study evaluated the outcomes of ESD in early malignant lesions and found high en bloc resection rates but modest curative resection rates in Germany. High-volume centers had better outcomes compared to middle or low-volume centers, with factors like age, tumor size, and treatment location affecting non-curative ESD outcomes.

Summary: This study evaluated a new endoscopic platform called tissue retractor system (TRS) for use in endoscopic submucosal dissection (ESD). The results showed that TRS-assisted ESD is feasible and effective in the rectum, but there are still some technical limitations that need to be addressed.

Summary: Compared with ESD, ESD-ME achieved a higher histological complete resection rate, had a similar rate of complications, and required a similar procedure time for rectal NETs < 16 mm in diameter without metastasis.

Summary: This study examined the outcomes of salvage hybrid ESD (SH-ESD) and identified its indications for cases with remaining undissected submucosa less than 20mm in diameter. SH-ESD can be an alternative surgical method with shorter procedure time and comparable en bloc resection rate.

Summary: The study evaluated the efficacy of a novel fully covered self-expandable metal stent (SEMS) for the palliation of distal biliary obstruction (DBO) caused by unresectable pancreatic cancer (UPC). The results showed that the incidence of recurrent biliary obstruction (RBO) was lower and the time to RBO (TRBO) was longer in the HFS group compared to the other two groups. Additionally, the incidence of complications was lower in the HFS group. Therefore, the use of HFS stent is recommended for the palliation of DBO due to UPC.
