  • Progress of Comparison between Minimally Invasive Video Assisted Thoracic Surgery and Traditional Median Sternotomy for Mitral Valve Surgery

    Cardiac surgery has a gradual change from traditional median sternotomy to minimally invasive surgery due to the appearance and application of peripheral extracorporeal circulation. There are great differences in the clinical practice of two different surgical methods in mitral valve operation. Minimally invasive thoracic surgery has the advantages of less trauma, less bleeding, faster recovery, beauty and so on. However, such surgery also has its weaknesses, such as longer learning curve, narrow operation space and high requirements of equipment. To compare the differences of early and long-term results in mitral valve operation between traditional median sternotomy and minimally invasive thoracic surgery is to better summarize and operate minimally invasive thoracic surgery for mitral valve surgery.

  • Clinical Pathology Research on Perineural Invasion in Hilar Cholangiocarcinoma

    ObjectiveTo summarize the incidence, patterns and laws of perineural invasion, and explore the path and the influencing factors of perineural invasion in hilar cholangiocarcinoma. MethodsA clinicopathologic study was conducted on sections from 52 patients with hilar cholangiocarcinoma to summarize the incidence and patterns of perineural invasion. The relationship of perineural invasion to lymph node metastasis, serum CA19-9, CEA, total bilirubin (TBIL) level, Bismuth-Corllet classification, or tumor penetration depth of bile duct walls was analyzed by association analysis. ResultsThe overall incidence of perineural invasion was 90.38% (47/52). However, the incidences of perineural invasion had no significant differences among various differentiated adenocarcinoma groups (P > 0.05). The incidences of perineural invasion were not correlated with the lymph node metastasis, serum CA19-9, CEA, TBIL level, and Bismuth-Corlette classification (P > 0.05), which was correlated with the tumor penetration depth of bile duct walls (P < 0.01). There were four patterns of perineural invasion, sequenced them according their incidences from high to low as follows: typeⅡ> typeⅢ> typeⅣ> typeⅠ. The pattern of perineural invasion was correlated with the degree of tumor differentiation (χ2=31.04, P < 0.01). ConclusionsThe incidence of perineural invasion is very high in hilar cholangiocarcinoma. The patterns of perineural invasion are similar in the same patient, and a variety of invasion patterns might coexist. While the pattern of perineural invasion is correlated with the degree of tumor differentiation. The incidence of perineural invasion is correlated with the tumor penetration depth of bile duct walls.
