●Theme Sessions

General 1 Symposium　　*English Session
Minimally Invasive Treatment in the Collaboration between GI Endoscopists and Surgeons

Moderators:
Ichiro Takemasa　（Osaka International Medical ＆ Science Center）
Kazuki Sumiyama　（Department of Endoscopy, The Jikei University School of Medicine）

>>Introduction

We are pleased to invite you to submit abstracts for the upcoming session on “Minimally Invasive Treatment in the Collaboration between GI Endoscopists and Surgeons” at the 109th JGES Meeting 2025 in Sapporo, Japan.
The session aims to explore the synergistic relationship between gastrointestinal endoscopists and surgeons, highlighting innovative techniques, collaborative approaches, and the latest advancements in the field. We welcome presentations that address clinical questions raised from available evidence, including: Whether LECS could be less invasive and safer than reduced port surgery or endoscopic tissue resection techniques; Whether EFTR could achieve better outcomes than LECS in selective cases or at selective hospitals; Challenges associated with collaboration among staff in other specialties or occupations; Innovative technologies to overcome existing challenges; Collaboration outside the GI field.

General 2 Symposium　　*English Session
Current status and future perspectives of AI in gastrointestinal endoscopy

Moderators:
Yutaka Saito（National Cancer Center Hospital, Endoscopy Division）
Masashi Misawa（Showa University Northern Yokohama Hospital, Digestive Disease Center）

>>Introduction

The advent of deep learning has significantly advanced AI technology, enabling its integration into clinical practice. In gastrointestinal endoscopy, several AI-based software, including EndoBRAIN, are commercially available for both upper and lower GI procedures. Recent studies have demonstrated the clinical utility of these technologies. In addition, advances in AI have promoted research into AI-based risk stratification for pathological images and the application of generative AI, thereby broadening the scope of AI research in endoscopy. This session invites presentations on various AI technologies related to endoscopic practice, whether currently available on the market or in development, to examine the current state and challenges of these technologies. Papers addressing the potential drawbacks of AI in clinical applications are also encouraged to stimulate discussion on the future prospects of AI.

Upper GI 1 Symposium　　*English Session
Pathological and endoscopic diagnosis of superficial neoplasias derived from long segment
Barrett’s esophagus “How to overcome the gap with the West”

Moderators:
Tsuneo Oyama（Endoscopy, Saku Central Hospital Advanced Care Center）
Hitomi Minami（Department of Gastroenterology and Hepatology,
Nagasaki University Hospital）
Hiroshi Kawachi（The Cancer Institute Hospital of JFCR）

Designated Speaker:
Michael Vieth　（Klinikum Bayreuth, Germany）

>>Introduction

Barrett's esophageal cancer has been increasing in Japan in recent years. Tumors that occur in Barrett's esophagus are classified as low-grade dysplasia, high-grade dysplasia, and adenocarcinoma in Western countries, but the Japanese guidelines only define adenocarcinoma and do not define dysplasia.
Meanwhile, random biopsies are recommended for endoscopic diagnosis in Western countries, whereas targeted biopsies based on endoscopic findings are more commonly performed in Japan. Discrepancies still exist in pathological and endoscopic diagnoses between Japan and the West.
For this symposium, we have invited Professor Michael Vieth, an outstanding German pathologist, to discuss the current state of pathological and endoscopic diagnosis of superficial tumors occurring in the long segment Barrett's esophagus, and to explore ways to overcome the gap with Western countries.

Lower GI 3　Symposium　　*English Session
Endoscopic evaluation of ulcerative colitis-scientific focusing on mucosal healing-

Moderators:
Hiroshi Nakase（Hiroshi Nakase, Sapporo Medical University School of Medicine ）
Motohiro Esaki（Department Faculty of Medicine, Medicine, Internal Medicine, Saga University）

Designated Speaker:
Raf Bisschops (Head of the clinic/Associate professor, Catholic University of Leuven (KU Leuven), Faculty of Medicine, Belgium)

>>Introduction

With the advances in medical management for ulcerative colitis (UC), there has been an increasing demand for sophisticated treatment strategies with the idea of improving long-term disease prognosis. Such therapeutic strategies, recently called treat-to-target strategies, have set mucosal healing as a long-term therapeutic goal generally assessed using the Mayo Endoscopic Subscore. However, mucosal healing still needs to be clearly defined, and some related issues, including endoscopic activity index to be used and interobserver variation, remain unsolved. Furthermore, because of the invasiveness and cost of endoscopic examination, the usefulness of biomarkers for predicting mucosal healing has been enthusiastically investigated. In this symposium, we would like to have a scientific discussion concerning recent evidence and problems of endoscopic evaluation of UC.

The poster presentation format will be announced in late February 2025.
