Abstract
In spite of recent advances in various techniques of biliary endoprosthesis in patients with malignant biliary obstruction, there still remain some problems such as insufficient relieving of jaundice, cholangitis, colgging of stent limitation to the patient's daily life, etc. Intraoperative retrograde transtumoral biliary endoprosthesis with 10 Fr. or 7.2 Fr. polyethylene tube was attempted in 6 cases of unresectable hilar bile duct carcinoma. In all of 5 cases with icterus, it's relief was achieved within a month. In the remaining nonicteric case, the procedure prevented the development of jaundice. In 3 cases who survived longer than 12 months (15,28,45 months), the tube maintained its patency for 12,21 and 41 months respectively. Except of one case who developed clogging of the 7.2 Fr. endoprosthesis, all the other patients enjoyed their life without any limitations.
Thus we conclude that our method of intraoperative retrograde transtumoral biliary drainage is an effective palliative treatment against unresectable hilar bile carcinomas.
