Endoscopic Ultrasound Radiofrequency Ablation, Database Repository

Study Overview
=================
Brief Summary
-----------------
The purpose of having this database is to collect data related to endoscopic ultrasound RFA procedures performed by Indiana University EUS physicians for the treatment of tumors or adenopathy. This database is a repository database only, all information will be obtained in the electronic medical record. No additional clinical procedures will be performed outside current standard of care for endoscopic ultrasound. The patient will have already signed an informed consent for the endoscopic ultrasound. Subjects will be entered into the database for up to 10 years after the most recent procedure.

Detailed Description
-----------------
Radiofrequency ablation (RFA) is a well-established therapeutic option for ablation of dysplastic and neoplastic tissue by the use of local thermal coagulative necrosis. Options for administration include percutaneous or a surgical approach. Percutaneous RFA is effective and safe, but it is unfeasible in cases of lesions with interposition of organs and/or vessels. For lesions such as the pancreas, surgery-assisted RFA has been described but requires general anesthesia and is associated with a substantial risk of thermal injuries to major vessels or adjacent structures. EUS-guided RFA is a minimally invasive approach that offers high-quality real-time imaging guidance during selective ablation of benign (1-5) or malignant (6-7) pancreatic lesions. Treatment in small case series has shown to produce local necrosis with minimal adverse events. Other sites treated include the liver and metastatic adenopathy. This database will collect data related to endoscopic ultrasound RFA procedures performed by Indiana University EUS physicians for the treatment of tumors or adenopathy. No additional clinical procedures will be performed outside current standard of care for endoscopic ultrasound. The patient's information collected will be pre-procedure identification of the adenopathy, labs, the endoscopic ultrasound(s) and post procedure follow up and care related to the adenopathy. Patients will be contacted by phone at post-procedure 1 & 2 weeks and asked to report symptoms related to the procedure.
