Hi and welcome. There are benign and malignant possible causes. Benign stricture is seen in some cases and may be caused by inflammation or stone while malignant are caused by tumors. If there is jaundice then you should do surgical procedure and have stent put in. If not, then it can be observed for longer period. Wish you good health. Regards
