石垣一永教授の研究室では、超音波ガイド下生検（EUS-FNB）を用いた膵臓腫瘍の診断技術の高度化をめざしています。特に22ゲージのフランゼン針を用いた穿刺法の有効性や、診断精度の向上に寄与する技術的要因の解明が中心です。また、膵がん患者における血栓塞栓症の発生リスクや予後との関連についても臨床的疫学的アプローチをとっています。

The results of our retrospective analysis indicated that compared with a standard FNA needle, a 22-gauge Franseen FNB needle was associated with a higher first-pass tissue acquisition rate.
Thromboembolism was not uncommon in Japanese patients receiving chemotherapy for advanced pancreatic cancer and was associated with poor prognosis. Liver metastasis was the risk factor for TE.
The EUS-FNB using the 22-gauge Franseen needle for pancreatic solid lesions showed high per pass and overall diagnostic accuracy.
