About me

Stanley J. Pietrak, MD, is a board-certified gastroenterologist at MedStar Washington Hospital center. In addition to his dedication to general gastroenterology care, Dr. Pietrak diagnoses and treats both benign and malignant diseases of the bile ducts, pancreas, and the pancreatic ducts, with a focus on therapeutic endoscopy.

Dr. Pietrak utilizes endoscopic retrograde cholangiopancreatography (ERCP) and endoscopic ultrasound (EUS) to provide minimally invasive treatment of the bile and pancreatic ducts. His clinical interests include malignant and benign disorders of the bile ducts, malignant and benign disorders of the pancreas, advanced polypectomy removal, staging of luminal gastrointestinal cancer, and endoscopic luminal stenting. His research interests include pancreatic cancer screening and endoscopy training proficiency for gastrointestinal fellows.

Dr. Pietrak received his medical degree from Albany Medical College, where he was elected to the Alpha Omega Alpha Medical Honor Society. He completed a three-year residency in internal medicine at MedStar Georgetown University Hospital. He then joined Drexel University College of Medicine for a three-year fellowship in gastroenterology, where he was Chief Fellow. Before joining MedStar Washington Hospital Center, Dr. Pietrak completed a specialty fellowship in advanced gastroenterology therapeutics with MedStar Georgetown University Hospital. He is a member of the American College of Gastroenterology (ACG), the American Gastroenterological Association (AGA), and the American Society for Gastrointestinal Endoscopy (ASGE).

Dr. Pietrak is passionate about the early detection and management of patients with pancreatic cysts.

Philosophy of Care
“In order to maximize the quality and effectiveness of the care I provide, I strive to practice evidence-based medicine with a patient-centered focus. While we must acknowledge the recommendations of national guidelines and landmark clinical research trials, each patient presents us with a unique situation or condition. As a result, we must not only focus on treating their medical issues, but also their individual concerns and needs.”
