The Mayo Clinic Upper Digestive Disease Survey has been created in order to have a consistent evaluation tools for patients undergoing esophageal reconstruction or treatment  or patients that are experiencing an upper digestive disease in order to standardize and validate outcome measures.  Data will be used to establish the validation of the questionnaires/survey.  Data will also lead to the establishment of “normal” or expected scores for patients undergoing each type of esophagectomy procedure and for upper digestive diseases.  Data will contribute to creating treatment algorithms for symptom management for upper digestive diseases and for post-operative complications and symptoms as well as contribute to pre-operative education.  

The purpose of this study is to characterize post-surgical drain fluid, pleural fluid, collected from the drainage device placed during surgery, as a biomarker for molecular residual disease in patients with non small cell lung cancer.

The purpose of this study is to collect blood and tumor tissue from esophageal cancer patients in order to identify specific esophageal cancer mutations that can be measured in the blood (cell free DNA) during the course of treatment as a marker of response and recurrence.
