肝炎后肝硬变时肝脏体积测量及其变化的研究

Ameasurement of liver volume and its changes in post-hepatitic cirrhosis

作者利用数字图象处理系统和“三维信息提取与三维图象重建”软件，成功地测量出活体肝脏体积，重建出活体肝脏三维图象。临床应用于有外科并发症的肝炎后肝硬变６２例，非肝硬变１５例。首次以具体量化的指标证明：国人肝炎后肝硬变时：（１）肝脏体积明显缩小，其均值为４７４．６４±１１５．２８ｃｍ￣３／ｍ￣２，与对照组的差异有显著性（Ｐ＜０．００１）；（２）肝体积与肝功能有关，肝功能Ⅰ级者的肝体积较大，但并非“肝功能越好，肝体积就越大”；（３）肝体积与手术耐受性有关，其手术风险判断界值为４００ｃｍ￣３／ｍ￣２；Ⅰ级肝功能时可达３００ｃｍ￣３／ｍ￣２；（４）分流加断流术后肝体积明显缩小，而断流术后肝体积变化不大。

AbstractBy use of the computerized digital image process-ing system,the liver volume in vivo was successfullymeasured and the three-dimensional image of the liverrebuilt in 62 cases of posthepatitic cirrhosis and 15noncirrhotics。It was found (1)The liver volume of474.64±115.28cm￣3/m￣2 in Chinese cirrhotics is signifi-cantly smaller than that of the control(P<0.001 ):(2)In most cases, patients in class Ⅰ of the liver func-tion have a larger liver volume;(3)Patients withsmaller liver volume have poor tolerance to surgerywith a critical value of 400cm￣3/m￣2;(4)the liver vol-ume considerably reduced after,hunt plus devascular-ization but did not change after devascularization only.
