Evaluation of Outcomes from Treatment of Benign or Malignant Gastroesophageal Diseases

Overview

This study will be a retrospective chart review of patients who have been diagnosed with benign or malignant pancreatic disease under the practice of Dr. Rohan Jeyarajah, M.D., Dr. Houssam Osman M.D., and Dr. Edward Cho M.D., Sc.M. at Methodist Health System Hospital in Richardson, TX. The Investigators plan to conduct an analysis of patients meeting the inclusion criteria from 2005 to present. Study will also be conducted by the PI, Sub-Is, surgery fellows, office staff and clinical research coordinator who are delegated to do by the PI. Data will be obtained by looking through either the investigator's patients from their practice or through a national database. Data will be analyzed primarily by the study conductors.

1\. INTRODUCTION 1.1. Background It is reported in the literature that the treatment of any gastroesophageal disease process, whether benign or malignant, continues to be a huge challenge. For example, patients with esophageal cancer continue to be diagnosed at an advanced stage with medical and surgical options that are improving in terms of outcome measurements but with much more room for improvement. The Primary investigtor goal is to continue to review patient treatment outcomes to further improve overall survival, overall symptom control, mortality and morbidity. 1.2. Aim(s)/Objective(s) The main aim of this study is to evaluate and compare the outcomes from the investigator's treatment of benign or gastroesophageal diseases. 1.3. Rationale for the study There is a need to understand and improve the current diagnosis and treatment algorithm for gastroesophageal pathologies. Continued evaluation and study is imperative to ensure that national guidelines are improving to enhance patient cure and/or recovery. 2\. OBJECTIVES AND STUDY OUTCOME MEASURES 2.1.

Categorical outcomes will be analyzed using chi-square test or Fisher's exact test for smaller samples. 6\. ETHICS/PROTECTION OF HUMAN SUBJECTS 6.1. Ethical Standard 6.1.1. The following safeguard will be employed to protect confidentiality of data * Limitation of access to data * Minimal HIPAA identifiers on data collection tools * Password protected share drive database on computer * Use of locked file cabinets for physical records (if any collected) * Restricted access to share drive database on computers * Appropriate training of personnel accessing share drive database * At close of this study, all identifiers will be removed from the data collection tools 6.2. Institutional Review Board The protocol and all study related materials will be submitted to the IRB for review and approval. Approval of both the protocol and study related material will be obtained before any clinical data is collected. Any amendment to the protocol will require review and approval by the IRB before the changes are implemented in the study. 6.3. Informed Consent Process 6.3.1. Details to waive consent for this retrospective chart review • This research is not regulated by the FDA * The research involves no more than minimal risk to the subjects * The waiver or alternation will not adversely affect the rights or welfare of the subjects * The research could not practicably be carried out without the waiver * It is not feasible to provide subjects with pertinent information after participation 6.4. Participant Confidentiality * All data collection will be kept in password protected hospital server * Only authorized personal will have access share drive * Patient confidentiality will be maintained at all times, complying with HIPAA guidelines. 7\.
