We sincerely welcome the submission of outstanding research that will contribute to defining the next generation of endoscopic imaging and to advancing the future of gastrointestinal endoscopy.

Upper/Lower2 Panel Discussion
Current status and future prospective of water/gel immersion endoscopy

Chair Hironori Yamamoto (Department of Endoscopic Research and International Education (Funded by FUJIFILM Medical Co., Ltd), Jichi Medical University)
Noriya Uedo (Osaka International Cancer Institute)

Introduction

In recent years, the clinical application of water/gel immersion endoscopy has expanded rapidly in both upper and lower gastrointestinal endoscopy. This technique is now used in a wide range of procedures, including diagnosis, treatment, and wound closure. The stable endoscopic view, buoyancy, and reduced luminal tension provided by underwater/gel environments have enabled novel diagnostic and therapeutic approaches that are difficult to achieve with conventional gas-insufflation endoscopy. However, important questions remain regarding its optimal indications, limitations, standardization of techniques, and device selection. In this panel discussion, experts from various fields will share their latest insights and practical experiences with water/gel immersion endoscopy. Together, we aim to clarify its current status and future prospective, and explore whether this technique represents a temporary boom or a true paradigm shift in endoscopy.

Upper/Lower3 Workshop
Frontiers of Endoscopic Full-Thickness Resection and Endoluminal Closure

Chair Yutaka Saito (Endoscopy Division, National Cancer Center Hospital)
Takashi Toyonaga (Division of Gastroenterology, Kobe University Graduate School of Medicine)

Introduction

Full-thickness resection of the gastrointestinal tract (EFTR), muscularis resection (EMD/PAEM/EID), and advanced endoluminal closure techniques are rapidly gaining popularity and evolving worldwide as a new paradigm in minimally invasive treatment.
For this workshop, we are seeking a wide range of contributions covering the latest insights in this field, including site-specific indications, strategies for managing complications, the utility of new devices, and long-term prognosis.
We plan to engage in lively discussions from an international perspective alongside our panel of commentators.
We sincerely look forward to receiving numerous enthusiastic abstract submissions from both Japan and abroad that will help standardize these procedures and pave the way for future advancements.

Upper3 Workshop
The Role of Endoscopy in Multidisciplinary Treatment for Head and Neck and Esophageal Cancers

Chair Yuichi Shimizu (Department of Gastroenterology, National Hospital Organization, Hokkaido Medical Center)
Ryu Ishihara (Osaka International Cancer Institute Gastrointestinal oncology)

Introduction

Multidisciplinary management incorporating chemotherapy, radiotherapy, surgery, and endoscopic therapy has become an integral component of treatment for head and neck and esophageal cancers. Within these treatment strategies, endoscopy plays important roles not only as a diagnostic tool for assessing responses to chemotherapy and radiotherapy, but also as a local therapeutic modality for managing residual or recurrent lesions after treatment. More recently, endoscopy has attracted attention as a potential means of delivering viral agents in oncolytic virus therapy. Despite these diverse applications, however, its benefits, limitations, and unresolved challenges in the multidisciplinary setting have yet to be fully elucidated. This session aims to discuss the diverse roles of endoscopy in the multidisciplinary management of head and neck and esophageal cancers. We welcome submissions from a broad range of perspectives, including diagnosis, treatment, and drug delivery and other related applications of endoscopy. Presentations describing innovative approaches to overcoming existing challenges are particularly encouraged, even when based on small case series or preliminary experiences.

IBD1 Symposium
Future-Oriented Endoscopy in Inflammatory Bowel Disease

Chair Hiroshi Nakase (Division of Gastroenterology and Hepatology, Department of Internal Medicine, Sapporo Medical University School of Medicine)
Ken Sugimoto (Hamamatsu University School of Medicine, First Department of Medicine)

IBD5 Workshop
Endoscopic Assessment and Biomarkers in IBD: Current Status, Challenges, and Future Perspectives

Chair Tadakazu Hisamatsu (Department of Gastroenterology, Kyorin University School of Medicine)
Makoto Naganuma (Third Department of Internal Medicine)

Introduction

Endoscopy remains the cornerstone of disease assessment in ulcerative colitis and Crohn’s disease, providing essential information on disease activity, extent, therapeutic response, mucosal and histological healing, and surveillance for colitis-associated neoplasia. At the same time, the widespread adoption of treat-to-target strategies has increased the need for reliable and less invasive tools for longitudinal disease monitoring. Biomarkers such as fecal calprotectin (FC), leucine-rich alpha-2 glycoprotein (LRG), PGE-MUM, and other emerging blood- and stool-based markers have demonstrated associations with endoscopic inflammation and clinical outcomes, and are increasingly being incorporated into routine disease monitoring.
Recent advances in magnifying and image-enhanced endoscopy, ultra-high magnification imaging, and artificial intelligence (AI)-assisted image analysis have further improved the assessment of mucosal inflammation and neoplastic lesions. In addition, therapeutic endoscopy has expanded its role in the management of IBD-related complications, including strictures and colitis-associated neoplasia. Furthermore, translational research utilizing endoscopic biopsy specimens has accelerated the discovery of novel biomarkers and molecular pathways, paving the way toward precision medicine in IBD.
This session invites submissions focusing on endoscopic diagnosis and therapy, biomarkers for disease monitoring, correlations between biomarkers and endoscopic outcomes, AI-assisted technologies, and translational research utilizing endoscopic specimens. We particularly welcome studies addressing how endoscopy and biomarkers can be integrated to optimize treat-to-target strategies and improve patient outcomes. Through this session, we aim to discuss the current strengths and limitations of these approaches and explore future directions in precision monitoring and management of IBD.

Pancreatobiliary3 Panel Discussion
New Standards in the Management of Walled-Off Necrosis: Toward Optimized and Individualized Treatment Strategies

Chair Yousuke Nakai (Tokyo Women's Medical University, Department of Gastroenterology)
Hideyuki Shiomi (Division of Hepatobiliary and Pancreatic Diseases, Department of Gastroenterology, Hyogo Medical University)

Introduction

Management of WON has evolved toward a minimally invasive step-up approach combining endoscopic, percutaneous, and surgical interventions. EUS-guided drainage, particularly using LAMS, has become a treatment cornerstone. However, LAMS alone is not sufficient for all patients, and additional interventions including endoscopic necrosectomy is often necessary. Optimal management depends on various factors, including the size and morphology of WON, necrotic burden, infection, bleeding risk, patient condition, and local expertise. In this session, the "New Standard" in WON management, focusing on the entire treatment strategy, is to be discussed. Topics include timing and indication of intervention, stent selection, adverse event management, multidisciplinary collaboration, imaging-based assessment, follow-up strategies, and referral of complex cases.

Pancreatobiliary8 Workshop
The Trans-ESCR Approach: Current Status and Future Perspectives

Chair Hiroyuki Isayama (Department of Gastroenterology, Graduate School of Medicine, Juntendo University)
Kazuyuki Matsumoto (Department of Endoscopy, Okayama University Hospital)

Introduction

ESCR (Endosonography-/EUS-guided Created Route) is a newly proposed general term created by EUS-guided procedures for drainage or anastomosis. In recent years, the Trans-ESCR approach, encompassing endoscopic necrosectomy, EUS-guided antegrade interventions, EUS-directed transgastric ERCP (EDGE), and the rendezvous technique, has become an important therapeutic strategy in pancreatobiliary endoscopy. However, these procedures remain technically demanding and require appropriate route selection, optimal device selection, and careful management of procedure-related adverse events.
This workshop will focus on pancreatobiliary endoscopic interventions performed via Trans-ESCR. We welcome presentations on stone extraction, the treatment of benign and malignant strictures, and other therapeutic applications of the Trans-ESCR approach. Although endoscopic necrosectomy is included within the concept of Trans-ESCR, it will not be covered in this workshop. Presentations highlighting procedural strategies, device selection, technical innovations, and the management of challenging cases are particularly encouraged.
Through active discussion, we aim to clarify the current role of the Trans-ESCR approach, explore future directions, and promote its safe and effective integration into clinical practice.
