The Japan Gastroenterological Endoscopy Society (JGES) hosted four symposia from 2021 to 2022, focusing on advanced diagnostic endoscopy for upper gastrointestinal issues.
Each session included multiple studies addressing challenges, diagnostic advancements, and the incorporation of artificial intelligence in endoscopy.
The discussions aim to enhance understanding of current practices and inspire future developments for effective clinical endoscopic diagnostic systems.
This study investigates long-term surveillance for gastric cancer, particularly focusing on cases diagnosed 10 or more years after initial treatment.
It analyzes 377 patients across 14 institutions, revealing that invasive cancers diagnosed after 10 years tend to be more aggressive and have a higher pathological stage compared to those diagnosed sooner.
The findings emphasize the importance of ongoing surveillance for all patients, regardless of mucosal atrophy, especially after 10 years post-eradication.
The study focused on differentiating between undifferentiated-type and differentiated-type early gastric cancers (EGC) to guide endoscopic resection decisions.
It tested the effectiveness of white-light endoscopy (WLE) and magnifying narrow-band imaging (M-NBI) in diagnosing these types of EGCs, with M-NBI using specific patterns to identify undifferentiated tumors.
Although both methods showed similar overall accuracy, M-NBI was found to have significantly higher specificity, which could help in minimizing unnecessary surgeries by preventing misdiagnosis.
