Yosuke Tsuji教授の研究室では、消化器内視鏡治療、特に内視鏡的粘膜下層剥離術（ESD）の安全性と技術習得に注力しています。特に初心者エンドスコピストのための教育訓練プログラムの構築とその有効性の検証が中心で、専門医の指導下での実地訓練と事前の集中学習を組み合わせた教育法が特徴です。また、ESD後の出血リスク要因の解明や、臨床的成績に影響を与える要因の同定も進めています。

Beginner coagulators, tumor in the antrum, and medicines were significant risk factors for post-ESD bleeding. Bleeding at the ulcer margin frequently occurred with beginner operators.
Endoscopic submucosal dissection (ESD) has become widely accepted as a standard method of treatment for superficial gastrointestinal neoplasms because it enables en block resection even for large lesions or fibrotic lesions with minimal invasiveness, and decreases the local recurrence rate. Moreover, specimens resected in an en block fashion enable accurate histological assessment. Taking these factors into consideration, ESD seems to be more advantageous than conventional endoscopic mucosal res
Our training system enabled novice operators to perform gastric ESD without a decline in clinical outcomes. Key features of this training are prior intensive learning and actual ESD during the learning period under expert supervision.
