Professor Kazunaga Ishigaki's research lab specializes in gastrointestinal endoscopy and interventional radiology, with a focus on improving diagnostic accuracy and safety in pancreatic and solid organ lesions. The lab investigates advanced needle techniques, such as EUS-Fine Needle Biopsy (EUS-FNB) using 22-gauge Franseen needles, to enhance tissue acquisition and diagnostic yield. It also explores clinical complications like thromboembolism in patients with advanced pancreatic cancer, particularly in relation to liver metastasis and prognosis. The lab’s work bridges interventional endoscopy with oncological outcomes, aiming to optimize patient management through precise, minimally invasive diagnostics.
Figures are computed from collected data and may differ slightly.
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.
