[Usefulness of sequential isotopic cholangiography in biliary surgery follow-up]

Personal experience in the follow-up of 39 patients subjected to bile duct surgery is reported. The results indicated that sequential isotopic cholangiography is less effective as a supplementary examination in the postoperative period by comparison with its use in preoperative diagnosis. It does, in fact, constitute the only possibility of visualising the main biliary pathway in subjects who have been operated for biliodigestive anastomosis, with the exception of invasive methods, such as PTC, itself out of the question in the execution of periodic postoperative controls.
