Welcome To The Forefront At the University of Chicago Medicine Center for Endoscopic Research and Therapeutics (CERT), our experts annually perform thousands of specialized therapeutic endoscopy procedures. Our interventional endoscopy program attracts both patients and physicians from around the country and internationally due to our expertise, innovation, patient focus and strong partnerships. We use innovative endoscopic techniques to provide minimally invasive solutions for a range of gastrointestinal problems. Our physicians developed or perfected many of the techniques we use, and we strive to push the boundaries of endoscopic technology for the benefit of patient care and outcomes. As we continue to innovate and strive to provide the best care for patients, we also commit to expanding and strengthening our relationships with our referring physicians. We are grateful for your continued collaboration and invite you to learn more about our distinguished program.
