High-intensity focused ultrasound (HIFU) is a novel advanced therapy for unresectable pancreatic cancer (PC). HIFU therapy with chemotherapy is being promoted as a novel method to control local advancement by tumor ablation. We evaluated the therapeutic effects of HIFU therapy in locally advanced and metastatic PC. PC patients were treated with HIFU as an optional local therapy and systemic chemotherapy. The FEP-BY02 (Yuande Bio-Medical Engineering) HIFU device was used under ultrasound guidance. Of ...

EUS-guided biliary drainage (EUS-BD) has recently been used for the treatment of not only malignant pancreaticobiliary diseases, but also for benign diseases. In most previous studies, EUS-BD was performed using a fully covered self-expandable metallic stent (SEMS), and data focusing on the usability of plastic stents for benign diseases are limited. We previously developed a plastic stent dedicated to EUS-guided hepaticoenterostomy (EUS-HES), and achieved favorable results in a feasibility study, ...

We herein report three cases of patients with an ampullary neuroendocrine tumor (NET), who underwent endoscopic papillectomy (EP). No tumor recurrence or metastasis was detected in the patients for more than two years after EP. Generally, surgical resection is recommended for ampullary NETs by the European Neuroendocrine Tumor Society. However, as EP is less invasive than surgical resection, there are some reports of low-grade small ampullary NETs curatively treated by EP with long-term follow-up. ...

Detection of pancreatic cancer (PC) at a resectable stage is still difficult because of the lack of accurate detection tests. The development of accurate biomarkers in low or non-invasive biofluids is essential to enable frequent tests, which would help increase the opportunity of PC detection in early stages.

Afferent loop syndrome is a complication that infrequently occurs after pancreaticoduodenectomy [1]. Complete obstruction occurs which leads to cholangitis, pancreatitis, perforation, and necrosis. In particular, patients with cancer recurrence cannot continue chemotherapy treatment, become debilitated, and may eventually die. Therefore, early and appropriate decompression treatment is needed.
