Biography
He is a board-certified Gastroenterologist with clinical interests in pancreaticobiliary diseases, gastrointestinal neoplasia, and related interventional endoscopic procedures. As an endoscopist, he has extensive experience in performing a variety of interventional endoscopic procedures. These procedures include endoscopic ultrasound (EUS)-guided procedures like fine needle aspiration/biopsy, injections, fiducial placement, pseudocyst drainage/necrosectomy, biliary drainage, gastrojejunostomy, transgastric ERCP, and needle-based confocal endomicroscopy for the evaluation of pancreatic cystic lesions. He also performs endoscopic retrograde cholangiopancreatography (ERCP), endoscopic mucosal resection, enteral and stenting, enteral feeding tube placement, as well as deep enteroscopy.
His research interest evolves around interventional endoscopy, more specifically in the evaluation of pancreatic cystic lesions. Dr. Eldika has received multiple awards in his career, his most recent one being the “Reviewer Award, April 2020,” for his superior contributions to the journal of Gastrointestinal Endoscopy, both through completing high numbers of reviews and for submitting the highest quality of work.
Dr. Eldika is a fellow of the American Society of Gastrointestinal Endoscopy. He is a member of the American Gastroenterological Association, American College of Gastroenterology, and American Pancreatic Association.
When not working Dr. Eldika enjoys reading, listening to music, watching sports and walking in nature.
