Minoda教授の研究室は、消化器内視鏡診断と治療の高度化を目的として、特に消化管腫瘍や胃腸間質腫瘍（GIST）の正確な診断に向けたエンドスコープ・超音波診断技術の革新を進めています。特に、EUS-FNAやEUS-AIを用いた胃・腸管における小巣病変の診断精度向上や、人工潰瘍の内視鏡的閉鎖技術（SCCT）の応用に注力しています。また、難易度の高い胆道・十二指腸エンドスコープ下切除（ESD）の安全性と有効性の検証も重要な研究テーマです。

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.
