Endoscopic ultrasound (EUS)-guided tissue acquisition has transformed the field by allowing access to pancreatic lesions through fine-needle and biopsy. However, diagnostic accuracy differs based on tumor characteristics and procedural factors. This narrative review explores the nuances of tissue acquisition methods for pancreatic tumors, including factors such as tumor location, size, histological characteristics, and needle selection. It assesses the efficacy of different needle designs and maneuvers, including suction techniques and needle passes. Moreover, the diverse tissue preparation methods, including cytological smear, cell block, and direct histology, are discussed, highlighting the importance of tailored approaches based on tumor characteristics. Additionally, the roles of macroscopic on-site evaluation and rapid on-site evaluation in optimizing specimen adequacy are investigated. Furthermore, percutaneous ultrasound-guided biopsy is considered an alternative approach, particularly in settings where EUS is impractical. Additionally, the review emphasizes the emerging trend of using tissue for genetic testing and molecular analysis, requiring high-quality sample acquisition. Future directions in tissue acquisition techniques and their integration into clinical practice are discussed, providing promising avenues for pancreatic disease diagnosis and treatment.</p>","PeriodicalId":72813,"journal":{"name":"Digestive endoscopy : official journal of the Japan Gastroenterological Endoscopy Society","volume":" ","pages":""},"PeriodicalIF":0.0,"publicationDate":"2024-12-25","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142900760","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}

The incidence rates range from 125 per 100,000 in northern China to 1-1.5 per 100,000 in the United States, driven by environmental and lifestyle factors such as tobacco and alcohol use, dietary habits, and pollution. Major modifiable risk factors include tobacco and alcohol consumption, with a synergistic risk increase when combined. Nonmodifiable risk factors include previous diagnoses of head and neck squamous cell carcinoma (H&N SCC), achalasia, and prior radiotherapy. Prevention strategies must be tailored to specific regional burdens to efficiently allocate medical and financial resources. Gastrointestinal endoscopy is crucial in reducing ESCC burden through early detection and characterization of neoplastic changes, such as high-grade dysplasia. Early diagnosis significantly improves survival rates, while endoscopic resection of noninvasive dysplasia can prevent ESCC onset, reducing treatment burden for advanced disease. Postresection surveillance can detect high-risk metachronous lesions. Despite these benefits, endoscopic prevention faces challenges, including the lack of high-level evidence supporting its efficacy, opportunity costs, the need for specialized training and techniques, and the requirement for advanced technology investments. This Position Statement from the World Endoscopy Organization (WEO) aims to address these challenges, supplying recommendations for the exploitation of endoscopic resources regarding the possible role of screening, quality, and training for the detection, characterization, resection, and surveillance of ESCC.</p>","PeriodicalId":72813,"journal":{"name":"Digestive endoscopy : official journal of the Japan Gastroenterological Endoscopy Society","volume":" ","pages":""},"PeriodicalIF":0.0,"publicationDate":"2024-12-25","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142900762","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}
