Dr. Darwin’s clinical focus is endoscopy, allowing for both the diagnosis and therapy of GI disorders. He performs Endoscopic Retrograde CholangioPancreatography  (ERCP), Spyglass cholangioscopy 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 method employed to allow access and therapy to the distal small intestine.

Dr. Darwin’s research stems from his endoscopic focus. The most recent projects include evaluation of different needle types for liver biopsy, limiting radiation exposure during ERCP and evaluation of neuroendocrine tumors of the pancreas. Additional projects and clinical efforts are done in conjunction with the UMMS multi-disciplinary GI oncology board for both GI and liver cancers.
