作者在台湾对接受非手术治疗而获成功的25例单个性阿米巴肝脓肿和26例单个性细菌性肝脓肿病人进行前瞻性超声波追踪研究,以了解肝脓肿的消散情况。两组病人的性别、年龄、病程和起初脓肿的大小均无明显差异。脓肿的体积用下列公式计算:若脓肿呈圆形,其体积为4/3πr~3,r 是脓肿的半径;若脓脓不呈圆形,其体积为 In Taiwan, the authors performed prospective sonographic follow-up studies of 25 patients with single amoebic liver abscess and 26 patients with single bacterial liver abscess who underwent nonsurgical treatment in Taiwan to understand the dissipation of liver abscess. There was no significant difference in gender, age, course of disease and initial abscess between the two groups. Abscess volume is calculated using the following formula: If the abscess is circular, its volume is 4 / 3πr ~ 3, r is the radius of the abscess; if the abscess is not circular, its volume is
