I recently had an ultrsound and a polyp was found by my bile duct. should i have the polyp removed?

Rare: It would be rare and unusual to find a polyp in the bile duct. Polyps are sometimes found in the gallbladder itself, and can usually be observed unless they are more than 1 cm in size. Polypoid tumors of the bile duct would be rare, and may need gastroenterology evaluation with ercp.

Rare, but...: Can be premalignant. I would advise excision, which can be difficult with ERCP and often requires open surgery. If malignant, radical excision is indicated.
