Research Interests:

Dr. Darwin’s clinical focus is endoscopy, allowing for both the diagnosis and therapy of GI disorders. I perform Endoscopic Retrograde CholangioPancreatography  (ERCP) and Endoscopic Ultrasound (EUS) for the diagnosis and treatment of bile duct stones, cancer of the pancreas and bile ducts, evaluation of jaundice, acute and chronic pancreatitis with complications and benign/inflammatory bile duct strictures. EUS is also utilized for staging of esophageal, gastric and rectal cancers, evaluation of submucosal lesions, fine needle aspiration to obtain tissue and EUS directed therapy. Dr. Darwin performs upper endoscopy and colonoscopy for removal of difficult polyps, control of bleeding and enteral stenting. Dr. Darwin also performs balloon enteroscopy, a new method employed to allow access and therapy to the distal small intestine.

Dr. Darwin’s  clinical research stems from my endoscopic focus. The most recent projects include a review of pancreatic duct stenting to facilitate bile duct cannulation, limiting radiation exposure during ERCP and evaluation of bile duct leaks.
