About Our Program
The Michigan Medicine Interventional Endoscopy Program strives to provide state-of-the-art clinical care, education, and research.
Our program includes five interventional endoscopists and three mid-level providers. Our faculty have contributed to the development of national guidelines on standard endoscopic practices, are part of journal editorial boards, and are often invited as speakers at national conferences.
We care for patients referred from all over the state of Michigan by cancer specialists, gastroenterologists, surgeons, and primary care providers. Our team offers expertise in pancreatobiliary endoscopy, third-space endoscopy, and bariatric endoscopy. Using a multidisciplinary approach and cutting-edge technologies, we provide care to patients with benign and malignant pancreatic disorders, gallbladder and bile duct diseases, cancers of the entire GI tract, Barrett’s esophagus, achalasia, obesity, post-surgical complications, and complex GI polyps.
We perform approximately 1,300 endoscopic retrograde cholangiopancreatography (ERCP) and 1,200 endoscopic ultrasound (EUS) procedures annually, in addition to a wide variety of other interventions. These advanced procedures are performed in the University of Michigan Health Medical Procedure Unit. Our three interventional rooms are equipped with the most advanced medical technology.
The program actively conducts clinical research in pancreatic and biliary disorders, early detection of pancreatic cancer, advanced imaging modalities, bariatric endoscopy, and novel endoscopic devices. In addition, our program is committed to the training of GI fellows and two fourth-year advanced endoscopy fellows per year.

Education and Training
The Interventional Endoscopy Program is committed to training the next generation of physicians in the field. We offer a one-year Interventional Endoscopy Fellowship for candidates who have completed an ABIM-certified three-year Gastroenterology Fellowship. Two positions are offered per year to qualified candidates.
The purposes of this training program are to provide fellows with the cognitive and technical skills to perform endoscopic retrograde cholangiopancreatography (ERCP), endoscopic ultrasound (EUS), and related endoscopic procedures at the expert level. The program seeks to train the future leaders of academic endoscopy in the United States as well as internationally.

Research and Clinical Studies
Our group is involved in a variety of research studies. Some of our research efforts are funded by the National Institute of Health, as well as philanthropic, industry, and University of Michigan sources. We conduct research in early detection of pancreatic cancer, pancreatic cysts, pancreatitis, advanced imaging modalities, bariatric endoscopy, and novel endoscopic devices. Our faculty publishes an average of 25 articles in peer-reviewed journals annually. Below is a non-exhaustive list of the current clinical studies that our group is involved:
