[The long-term results of surgical treatment in 103 cases of hilar cholangiocarcinoma].

We studied characteristics including clinicopathology, operation style, late survival rate of 103 patients with hilar bile duct carcinomas treated surgically in our hospital between 1986 and 1996. The factors affecting surgical treatment and late result of hilar bile duct carcinoma were analyzed. Of the 103 patients, subjected to 66 (radical resection, 36; palliative resection, 30) were section, and 37 (internal drainage, 11; external drainage, 26) were not. The total resectional rate was 64.1%. Operative mortality was 2.9% for palliltive or noresctive groups. In the radical resection group, the 1, 3 and 5-year survival rates were 96.7%, 23.3% and 13.2%, and the longest survival time was more than 8 years, whereas in the palliative resection group, the 3-year survival rate was only 3.8% and no one survived for over 5 years. In the unresected group, the survival time of the patients with internal drainage was longer than that of the patients with external drainage, but their viability was not improved significantly. Most of them died within 12 months. We proposed the new clinical types for hilar bile duct carcinoma. The pathological type in all patients survived for over 5 years was welldifferatiated papillary or tubular adenocarcinomas. The secondary operative rate in these patients was high. This showed that the biological characteristic is very important for the long-term results of bile duct carcinoma after operation.
