UNLABELLED Objectives. Radiofrequency ablation (RFA) has replaced photodynamic therapy for premalignant and malignant lesions of the esophagus. However, there is limited experience in the bile duct. The objective of this pilot study was to assess the safety and efficacy of RFA in malignant biliary strictures. METHODS Twenty patients with unresectable(More)
Backgrounds. Limited effective palliative treatments exist for pancreatic cancer which includes surgery or chemotherapy. Radiofrequency ablation (RFA) uses high frequency alternating current to ablate diseased tissue and has been used to treat various tumors. In this study, we evaluated a prototype probe adjusted to the EUS-needle to perform EUS-RFA to(More)
BACKGROUND/AIMS Photodynamic therapy (PDT) in unresectable cholangiocarcinoma has been associated with improved survival. We report a single tertiary care center experience over the past 6 years. METHODS Fifty-five patients with unresectable cholangiocarcinoma received PDT between 2004 and 2010. Plastic stents were placed after PDT to prevent cholangitis.(More)
Working with Profs. Henry Kapteyn and Margaret Murnane, I use femtoseond Ti:sapphire lasers to study the dynamics of molecules and nanomaterials on the femtosecond timescale. My thesis centers on extending Velocity Map Imaging (VMI) spectroscopy to nanomaterials and extreme-ultraviolet (EUV) wavelengths. I used NMR spectoscopy and computational chemistry to(More)
