Dr. Sedarat joined UCLA in 2013 as a member of the interventional endoscopy within the Vatche and Tamar Manoukian Division of Digestive Diseases. His clinical interests encompass the development and application of advanced endoscopic techniques and interventions to diagnose, stage, treat and palliate a range of benign and malignant gastrointestinal disorders. He is proficient in the application of advanced endoscopic techniques including therapeutic ERCP, EUS with fine needle aspiration and biopsy, ERCP in surgically altered anatomy, interventional EUS (such as biliary drainage or rendezvous procedures, pancreas pseudocyst drainage, pancreas necrosectomy, fiducial placement and abscess drainage), pancreatic and biliary endotherapy, endoluminal stenting, endoscopic mucosal resection (EMR), endoscopic submucosal dissection (ESD), complex polypectomy, tumor ablation, deep (device assisted) enteroscopy, endoscopic fistula and leak closure, complex stricture dilation and endotherapy, endoscopic treatment of Barrett’s esophagus with mucosal resection and radiofrequency ablation, endoscopic antireflux procedures, Zenkers’ diverticulum myotomy, endoscopic management of surgical complications, and chromoendoscopy. Dr. Sedarat also performs bariatric endoscopy, including primary endoscopic therapies for obesity, endoscopic treatment of weight regain following bariatric surgery, and treatment of post-surgical complications.

He started the program at UCLA to offer the POEM procedure (peroral endoscopic myotomy) as treatment option for patients with achalasia and spastic disorders of the esophagus.  His research interests include endoscopic device development and application as well as evaluation of existing and emerging endoscopic technologies with a focus on improving patient outcomes. He is interested in the application of the emerging fields of submucosal and transluminal endoscopy, including endoscopic submucosal dissection (ESD) for early tumor resection, POEM, and application of devices and techniques to treat gastrointestinal disorders that traditionally were managed surgically. 

Dr. Sedarat completed his residency in internal medicine at the University of Pennsylvania. He completed his fellowship in gastroenterology here at UCLA and returned to UPenn to complete an advanced endoscopy fellowship. He is board certified in gastroenterology and is a member of the American Society of Gastrointestinal Endoscopy.
