Bile duct stones are typically removed using endoscopic retrograde cholangiopancreatography (ERCP), a minimally invasive procedure that combines x-ray and upper endoscopyâan exam of the upper gastrointestinal tract, consisting of the esophagus, stomach and duodenum (the first part of the small intestine)âusing an endoscope, which is a lighted, flexible tube, about the thickness of a finger.
Removal of a thyroglossal duct cyst or sinus tract, also known as the âSistrunk procedureâ after Dr. Sistrunk, involves a neck incision with dissection up to a small bone in the upper neck called the hyoid bone.he hyoid bone is closely connected to the thyroglossal duct tract as it runs up to the deep substance of the tongue; therefore, the mid-portion of the hyoid bone is removed with a small amount of tongue tissue.
