Bio


Dr. Eldika received his medical education at the American University of Beirut. He completed his General Gastroenterology Fellowship at the State University of New York in Buffalo and Advanced Endoscopy Fellowship at the University of Virginia. At Ohio State University, he served as the Director of Interventional Endoscopy and Endoscopic Quality. His time at Ohio State University contributed to the growth and maturity of his experience and skills in interventional endoscopy. During his tenure there, he played a major role in building the program of interventional endoscopy in general, as well as interventional endoscopy for the pediatric age group, and the endoscopic quality program. Over the years, he was involved in training several gastroenterology fellows and interventional endoscopists. He recently joined Stanford University where he continues to practice interventional endoscopy and train fellows.
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.

Clinical Trials


  • Confocal Laser Endomicroscopy as an Imaging Biomarker for the Diagnosis of Pancreatic Cystic Lesions Recruiting

    The study schema is shown in Figure 4. (A) All patients referred to one of the participating academic centers for EUS evaluation of the PCL will be enrolled in the protocol if they satisfy inclusion criteria. Patient consent will be obtained during the clinic visit or prior to their EUS. EUS-guided nCLE imaging is first performed (B) followed by EUS-guided FNA and aspiration of cyst fluid. The cyst fluid is analyzed for CEA and cytology. As per institutional standard of care, the cyst fluid is also sent for molecular analysis. The results of the cyst fluid molecular analysis (B) will be utilized for the most likely diagnosis. Based on institutional multidisciplinary tumor board meetings, surgery is performed as indicated (C). Surgical histopathology serves as "gold standard" for diagnosis. It is anticipated that the majority of patients will undergo surgical resection after their EUS.
