Dr. Arvind Rengarajan joined the Department of Medicine in the Division of Gastroenterology as an Assistant Professor in July 2023. He attended Washington University in St. Louis for medical school, internal medicine residency, chief residency, and general gastroenterology fellowship. He then completed his additional therapeutic endoscopy training at Northwestern University. Dr. Rengarajan is an interventional gastroenterologist with specialized expertise in the diagnosis and treatment of pancreatic/biliary disorders and the management of gastrointestinal cancer. He is part of a multi-disciplinary team that incorporates state-of-the-art technology and the latest research and clinical knowledge into a comprehensive patient-centered care plan. He hopes to lead the initiative in third space endoscopy with techniques such as peroral endoscopic myotomy (POEM) and endoscopic submucosal dissection (ESD), both using a flexible endoscope as an alternative to invasive surgery in specific clinical situations.
Dr. Rengarajan is active in clinical research and has been invited to present his work at several national conferences. His research focuses on the use of high-resolution manometry in esophageal motor disorders, achalasia, and third space endoscopy (POEM/ESD). Specifically, he hopes to continue working on outcomes research allowing for further optimization of the management and treatment of achalasia with peroral endoscopic myotomy (POEM) and the removal of early cancers in the gastrointestinal tract using ESD. In addition to his clinical and research endeavors, he is passionate about mentorship and sponsorship of trainees. He also hopes to develop and refine a robust curriculum in endoscopic training for gastroenterology fellows. His clinical interest is pancreaticobiliary disorders and third space endoscopy. His research areas are achalasia and esophageal motility disorders outcomes research. Outside the hospital, Dr. Rengarajan enjoys spending time with his family, playing and watching basketball/football, reading mystery novels, and traveling to new locations.
