Professor Yosuke Minoda's research lab specializes in advanced endoscopic diagnostics and interventional gastroenterology, with a focus on improving the accuracy of subepithelial lesion (SEL) diagnosis using endoscopic ultrasound (EUS) and artificial intelligence. The lab investigates innovative techniques such as EUS-FNAB, EUS-AI systems, and novel endoscopic therapies like the SCCT for artificial ulcer closure. A key research direction involves optimizing endoscopic treatment of gastrointestinal stromal tumors (GISTs) and rare tumors such as glomus tumors, particularly in challenging anatomical sites like the duodenum. The lab also emphasizes clinical training and standardization of classification systems, such as the JNET classification, to enhance diagnostic consistency among endoscopists.

Although MIAB required longer procedural time, it outperformed EUS-FNAB when diagnosing gastric SELs smaller than 20-mm diameter.
The JNET classification system is a practical approach for the diagnosis of colorectal polyps. Training is required even for experienced colonoscopists to adopt the system properly. Common pitfalls must be shared among colonoscopists to improve the accuracy of the diagnosis.
Gastrointestinal stromal tumors (GISTs) are common subepithelial lesions (SELs) and require treatment considering their malignant potential. We recently developed an endoscopic ultrasound-based artificial intelligence (EUS-AI) system to differentiate GISTs from non-GISTs in gastric SELs, which were used to train the system. We assessed whether the EUS-AI system designed for diagnosing gastric GISTs could be applied to non-gastric GISTs. Between January 2015 and January 2021, 52 patients with non
The SCCT could be applied in the treatment of artificial ulcers in several parts of the GI tract with a high clinical success rate and no complications. The SCCT appears to be a good option for closing artificial mucosal ulcers.
A glomus tumor of the stomach is rare. It is difficult to diagnose the tumor before surgery by only endoscopic biopsy and radiography, and there is no established method of diagnosis before surgical treatment. Esophagogastroduodenoscopy (EGD) on a 50-year-old Japanese woman revealed a 10 mm submucosal tumor in the anterior wall of the gastric angle. Follow-up EGD revealed an increase in the size of the tumor to 15mm. Endoscopic ultrasonography (EUS) demonstrated a 15mm subepithelial hypoechoic s
Endoscopic submucosal dissection (ESD) is a minimally invasive method of treating early-stage tumors of the digestive tract. However, duodenal ESD is technically difficult, with high complication rates resulting from poor control of the endoscope, the thin duodenal wall, and the potential for exposure to pancreatic juices [1] [2]. This study evaluated the safety of ESD using the short-type Clutch Cutter for the removal of early duodenal tumors.
