 [ Symptoms ] had gallbladder surgery – feel i still have it – surgeon says encountered problems… [ Disease ] hi filling defect on a cholangiogram is definitely abnormal and it indicates that there was a obstruction in the path of bile duct you should have been informed about this for sure i dont see any reason why they must have hidden this fact from you at present the obstruction or the sphincter of oddi per se wont cause you any symptoms i personally feel that there might be some remnant remaining inside or a adhesion not removed other possibility is any intra operative trauma to the surrounding structures will cause such pain as this is quite common in such complicated cases thanks
