[Clinical value of "Kou mode of hepatic hilar anastomosis" in resection of type III or IV hepatic hilar cholangiocarcinoma].
OBJECTIVE
To evaluate the surgical technique of "Kou mode of hepatic hilar anastomosis" in the treatment for type III or IV hilar cholangiocarcinoma.


METHODS
The clinical data of 89 patients with type III or IV hilar cholangiocarcinoma surgically treated in our department between Jan. 1990 and Jan. 2008 were retrospectively analyzed. Since January 2000, "Kou mode of hepatic hilar anastomosis" was performed for some patients with advanced hilar cholangiocarcinoma. The patients were divided into two groups: group A treated between 1990 and 1999, group B between 2000 and 2008. The rate of resection, therapeutic efficacy and complications in these two groups were compared, respectively.


RESULTS
Of the 37 cases with hilar cholangiocarcinoma in group A, 4 were surgically treated (10.8%), with 1 (2.7%) radical resection and 3 (8.1%) palliative resection. Among the 52 cases with hilar cholangiocarcinoma in the group B, 35 (67.3%) received surgical resection, of them 15 (28.8%) underwent radical resection and 20 (38.5%) had palliative resection. Twenty-eight of these 35 cases underwent the "Kou mode of hepatic hilar anastomosis". The resection rate of advanced hilar cholangiocarcinoma in the group B was significantly higher than that in group A (P < 0.05). The complications in the 89 cases included ascites (3 cases), hemobilia (1 case), heart failure (1 case), and wound infection (2 cases). All the patients who were treated with the "Kou mode of hepatic hilar anastomosis" developed bile leakage to a varying degree and recovered after drainage and symptomatic treatment.


CONCLUSIONS
The resection rate of type III or IV advanced hilar cholangiocarcinoma can be remarkably improved by using a novel alternative surgical technique called "Kou mode of hepatic hilar anastomosis". However, the long-term outcome still needs to be determined by close follow-up and further observation.
