MO9-2 Usefulness of EUS-FNA for diagnosis of intraperitoneal tumors other than hepatobiliary and pancreatic cancer

Abstract

In primary or metastatic intraperitoneal tumors(PMIT), there is a limitation of percutaneous biopsy, especially for pancreatic or lymph node metastasis. Therefore, endoscopic ultrasound-guided fine-needle aspiration(EUS-FNA) is an option for biopsy. Diagnosis of pancreatic cancer by EUS-FNA has been reported to be high sensitivity (89-92%). However, the usefulness of EUS-FNA in the diagnosis of other organ tumors has not yet been fully investigated. In this study we investigated the diagnostic ability and safety of EUS-FNA for PMIT other than hepatobiliary and pancreatic cancer.
