[Multivariate analysis of the effect of two liver resection methods on the survival outcome of patients with intrahepatic cholangiocarcinoma].

To investigate the effect of anatomical hepatectomy and non-anatomic hepatectomy in the treatment of elderly patients with intrahepatic cholangiocarcinoma (IHCC) and their impact on survival outcomes. In this study, a retrospective method was used to select elderly patients with IHCC who were surgically treated in Shangqiu First People's Hospital from April 2014 to April 2018, and were divided into anatomic resection group and non-anatomical resection group according to the surgical methods they received.The factors affecting the survival outcome of IHCC in the two liver resection methods were analyzed and compared, as well as the effects of liver cirrhosis rate, TNM stage, ascites rate, lymph node metastasis rate, and vascular invasion rate on survival. A total of 181 cases were included in this study, including 87 cases in the anatomical resection group, with 54 males and 33 females, aged (71.4±5.2) years old;There were 94 cases in the non-anatomical resection group, including 49 males and 45 females, aged (70.8±4.8) years.The 3-year survival rate of the anatomical resection group was 41.4% (36/87), which was higher than that of the non-anatomical resection group (25.5% (24/94), the difference was statistically significant (<0.05);The median survival time of the anatomic resection group was longer than that of the non-anatomical resection group, and the difference was statistically significant <0.05;The patient's TNM stage was stage III [ (95%): 2.168 (1.245-3.776)], lymph node metastasis [1.664 (1.087-2.545)], and vascular invasion [1.883 (1.167-3.038)] was an independent risk factor for death 3 years after surgery (<0.05), The patient's anatomical liver resection was a protective factor for the 3-year follow-up survival (<0.05). The postoperative survival of elderly patients with IHCC is affected by many factors, but anatomic liver resection is beneficial to prolong the survival time of patients.
