Since its inception, NOTES has faced challenges such as technical complexity and securing safe access closure, which initially limited its widespread adoption. However, advancements in endoscopic techniques and technology, closure devices, and hybrid approaches may revitalize its clinical utility. Hybrid NOTES, particularly transvaginal techniques, has demonstrated significant benefits, including reduced postoperative pain, faster recovery, and improved cosmesis, without compromising safety or efficacy. Innovations such as flexible endoscopic platforms, robotic assistance, and novel suturing techniques address previous limitations and enable broader applications across various gastrointestinal indications. Comparative studies have shown comparable outcomes between NOTES and traditional laparoscopy, with specific advantages in terms of patient comfort and recovery time. As technology evolves, NOTES continues to expand its clinical indications, and its future holds promise with the integration of robotics and artificial intelligence. Further research and structured training programs are crucial to overcome existing barriers and ensure safe and effective implementation in diverse clinical settings.","PeriodicalId":10351,"journal":{"name":"Clinical Endoscopy","volume":" ","pages":""},"PeriodicalIF":2.1,"publicationDate":"2025-07-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144526655","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Beginners focus on basic tasks, such as cecal intubation, while advanced trainees refine efficiency and complex techniques. Training prioritizes conscious competence through deliberate practice, reflection, and verbalizing actions; this enhances mindfulness and procedural expertise. Clear communication, standardized terminology, and constructive feedback ensure safety, confidence, and skill retention. SMART objectives-specific, measurable, achievable, relevant, and timely-help structure sessions for skill development and mastery. Simulation-based models support training at all the levels. Beginners benefit from cost-effective low-fidelity bench models and virtual reality (VR) simulators, which offer realistic tactile feedback and customizable scenarios. Studies have shown that both low- and high-fidelity models can effectively teach basic skills, although VR is preferred for foundational training. Advanced trainees utilize animal-based models for therapeutic interventions, three-dimensional printed models for pathology-specific practice, and hybrid models that combine VR and physical elements for enhanced realism. Augmented reality and haptic feedback systems refine advanced skills, but face developmental and cost challenges. Mentored live patient models excel in real-world decision-making, but raise ethical concerns. Training is tailored to individual needs, and competency-based training ensures mastery at each stage, from beginners to advanced practitioners.","PeriodicalId":10351,"journal":{"name":"Clinical Endoscopy","volume":" ","pages":""},"PeriodicalIF":2.1,"publicationDate":"2025-06-09","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144246761","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Traditional measurement techniques, including visual estimation and biopsy forceps, have significant interobserver variability and procedural inefficiencies. Recent advancements in digital measurement technologies, including virtual scale endoscopy (VSE) and artificial intelligence (AI)-assisted virtual rulers, have addressed these limitations. VSE projects a virtual scale onto endoscopic images, enhancing measurement precision and reducing variability. Several studies have demonstrated its superior accuracy compared with conventional methods; however, limitations such as increased procedure time and operator training requirements persist. AI-assisted virtual rulers utilize deep learning algorithms to automate lesion size estimation, significantly improving reproducibility and diagnostic reliability. Although these technologies offer promising improvements, challenges remain, including real-time integration, standardization, and regulatory approval. Future research should focus on refining AI models, expanding validation studies, and optimizing their usability in routine practice. A hybrid approach that combines AI automation with real-time digital tools may enhance the precision and efficiency of endoscopic lesion assessment, ultimately improving patient outcomes.","PeriodicalId":10351,"journal":{"name":"Clinical Endoscopy","volume":" ","pages":""},"PeriodicalIF":2.1,"publicationDate":"2025-05-23","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144126941","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Stent placement and exchange via endoscopic retrograde cholangiopancreatography biliary drainage risk traversing the HCC, a hypervascular tumor and causing bleeding. Endoscopic ultrasound-guided hepaticogastrostomy (EUS-HGS) potentially prevents procedure-related bleeding. Therefore, we evaluated the efficacy and safety of EUS-HGS as an alternative treatment for biliary obstruction in patients with HCC.Methods: This was a retrospective study of all EUS-HGS procedures performed in patients with HCC at the Aichi Cancer Center Hospital, Japan, from February 2017 to August 2023.Results: A total of 14 EUS-HGS procedures (42.9% primary) were attempted in 10 HCC patients (mean age 71.5 years, 80.0% male). Clinical and technical success rates were 92.9% and 90.9%, respectively. The observed procedure details in the 13 successful procedures included B3 puncture (53.8%), 22-G needle (53.8%), fully covered self-expandable metal stent (100%), and mean procedure time (32.7 minutes). There was no bleeding. Mild complications occurred in 27.3%.

This meta-analysis examines the prevalence of Barrett's esophagus, dysplasia, and EAC in patients with an irregular Z-line.Methods: We searched Medline, Embase, and Scopus databases up to October 2023 for studies on the prevalence of Barrett's esophagus, dysplasia, and EAC in these patients. A random-effects model was used for meta-analysis, and heterogeneity was assessed using I2 statistics.Results: Nine studies involving 17,637 patients were analyzed. Among those with an irregular Z-line, the prevalence of intestinal metaplasia was 29.4%. In patients with intestinal metaplasia, dysplasia was found in 6.2%, low-grade dysplasia in 5.9%, high-grade dysplasia in 1.6%, and EAC in 1.5%.
