Abstract:
This study shows a patient who presented with intermittent biliary tract obstruction caused by ampullary hamartoma. Endoscopic retrograde cholangiopancreatography showed a large ulcerated papilla and dilated biliary ducts. Tissue diagnosis was established by a large particle biopsy obtained with a snare. The patient underwent a successful endoscopic sphincterotomy and has remained symptom free for 4 years.
