Petros Benias MD

Dr. Petros C. Benias is an interventional gastroenterologist whose practice centers on complex, minimally invasive endoscopic therapies for pancreaticobiliary and early gastrointestinal tumors. He has extensive experience with third‑space endoscopy—including endoscopic submucosal dissection (ESD) for early neoplasia and per‑oral endoscopic myotomy (POEM) for achalasia, gastroparesis, and Zenker’s diverticulum.

Dr. Benias also advances care through research, mentoring, and protocol development, including same‑day discharge pathways and novel endoscopic therapies for GERD. A pioneer in advanced imaging, he helped introduce confocal endomicroscopy during EUS to characterize lymph nodes and pancreatic cysts, and his work describing gastrointestinal microanatomy has received national recognition.
