コメント

専門は消化器内視鏡で、特に食道疾患の内視鏡診断・治療を主たる研究テーマとしています。
今まで多くのクリニカルエビデンスを創出してきたと自負しており、例として、第二版の食道癌診断・治療ガイドラインに初めて記載された食道癌内視鏡的切除の絶対適応、 相対適応の基準は、我々が報告した長期成績の論文を主たる根拠としていました。
最新の2017年版のガイドラインでも引き続き、適応の根拠となる主要三論文のひとつとして引用されております。
また、ヨード染色PCサイン所見は日常臨床に広く浸透する早期食道癌診断基準となりました。さらに消化器からは少しはずれますが、頭頸部癌の診断治療に関する臨床研究も行っています。
我々が報告した下咽頭癌内視鏡的粘膜下層剥離術（ESD）の論文は世界初の頭頸部癌ESDの報告となり、以後、全国で頭頸部癌が早期発見され、低侵襲に根治されるきっかけになったと考えています。

趣味

B級アクション映画鑑賞、読書（主に青年マンガ）、飲酒、オーディオ（主にジャズ）、カメラ、ドライブ（ひらべったいアウディ）、スキューバダイビング、クレー射撃、等々、広く、極めて浅く。
