Sean B. Orenstein MD, MMS, FACS

Dr. Sean Orenstein is an Associate Professor of Surgery, joining OHSU and the Division of Gastrointestinal and General Surgery in 2014. His research interests include outcomes and improvements for minimally invasive and open hernia repair techniques, evaluation of hernia mesh prosthetics, and further exploration of the fusion between endoscopic and surgical techniques to improve patient outcomes and medical care.

Dr. Orenstein's residency and fellowship training allowed him to explore his passion for hernia repair, with specialized training in abdominal wall reconstruction for complex and recurrent abdominal hernias. During his fellowship, he also focused on minimally invasive surgical techniques such as laparoscopic hernia repair, laparoscopic foregut surgery, and laparoscopic diaphragmatic pacemaker placement for Amyotrophic Lateral Sclerosis (ALS) or spinal cord injury. His fellowship was also an avenue to receive specialized training on advanced endoscopy, including peroral endoscopic myotomy (POEM) for achalasia, endoscopic retrograde cholangiopancreatography (ERCP), and endoscopic stenting.
