title: Effect evaluation of vascular resection for patients with hilar cholangiocarcinoma: original data and meta-analysis.
abstract: To evaluate the effect of vascular resection (VR) in surgical management of hilar cholangiocarcinoma (HCCA), this report is used in a clinical analysis and conducted a systematic review, combined other studies, based on meta-analysis. 238 HCCA patients underwent hepatectomy in the Eastern Hepatobiliary Surgery Hospital. Binary logistic regression analysis was performed to investigate the potentially complicated associated factors. Kaplan-Meier test was employed to compare the long-term survival of patients in four groups (R0+PVR-free, R0+PVR, R1, and R2). Meta-analysis was performed using RevMan 4.3.2 software. The results suggested that hepatectomy and HAR were important negative factors from complications (p < 0.01). Compared with patients in other groups, survival of patients in R0+PVR group was worse than R0+PVR-free group, better than R2 group, and similar to R1group with p = 0.001, 0.047, and 0.606, respectively. The results of meta-analysis suggested patients who underwent VR had higher complications rate and mortality rate than patients who did not. Moreover, patients with vascular resection had lower long-term survival rate. VR used to be considered effective to the patients with vascular invasion. However, our study suggests that the surgical decision of undergoing VR should be made cautiously, since VR could diminish the survival time in some cases.
