肝脓肿经皮穿刺引流术的疗效及影响因素分析

目的 观察经皮穿刺引流对肝脓肿的治疗效果,分析影响疗效的因素,探讨降低病死率、并发症率,缩短住院时间的方法.方法 收集2011年1月至2016年1月收治的121例肝脓肿患者临床资料.对确诊肝脓肿患者,充分抗感染治疗的同时,CT评估病灶液化情况,在CT引导下行经皮肝穿刺引流,分析治疗后的病死率、并发症率、住院时间及其影响因素.结果 共有121例肝脓肿患者纳入研究.2例患者穿刺引流后死亡,病死率为1.6％,影响患者死亡率的因素为高龄、基础疾病,脓肿直径及实性成分;2例患者穿刺引流后出现肝周脓肿、腹壁脓肿,并发症率为1.6％,对并发症积极处理后达到临床治愈,影响并发症率的因素主要为手术操作欠妥;119例患者均达到临床治愈,治愈率为98.3％,平均住院时间为(15.1±6.0)d.影响住院时间的危险因素为:脓肿个数X6(r=0.232,P=0.021),脓肿大小X7(r=0.26,P=0.005),白细胞计数X8(r=0.238,P=0.009).进一步分析显示影响因素与住院时间相关性的多元线性回归方程有统计学意义(P＜0.05),多元回归方程为:Y=-3.438+3.055X6+0.527X7+0.297X8,F=5.819,R2=0.416.性别、年龄、糖尿病、致病原菌种类、脓肿位置对住院时间的影响无统计学差异(P＞0.05).结论 经皮穿刺肝脓肿引流术是治疗肝脓肿的有效方法,具有病死率低,并发症率低、住院时间短的特点.

Percutaneous puncturing drainage for the treatment of liver abscess: analysis of its curative effect and influence factors

Objective To evaluate the curative effect of percutaneous puncturing drainage in treating liver abscess,to analyze the factors affecting curative effect,and to discuss the methods ior reducing mortality and complication rate as well as for shortening hospitalization time.Methods Clinical data of 121 patients with liver abscess,who were admitted to authors' hospital during the period from January 2011 to January 2016,were retrospectively analyzed.For the patients with confirmed liver abscess,adequate antiinfective therapy was adopted,at the same time CT scan was performed to evaluate the liquefaction of lesion,and under CT guidance percutaneous puncturing drainage was carried out.The mortality,complication rate,hospitalization time and the factors affecting curative effect were analyzed.Results A total of 121 patients with liver abscess were enrolled in this study.Two patients died after percutaneous puncturing drainage,the mortality was 1.6％.The factors affecting mortality included old age,underlying disease,the diameter and solid components of abscess.Two patients developed peripheral hepatic abscess and abdominal wall abscess,the complication rate was 1.6％,and clinical cure was achieved after active treatment in these two patients.The main factor affecting complication rate was inappropriate surgical manipulation.Clinical cure was achieved in all 119 patients,with a cure rate of 98.3％,and the average hospitalization time was (15.1±6.0)days.The risk factors that affected hospitalization time included the number of abscess X6 (r=0.232,P=0.021),abscess size X7 (r=0.26,P=0.005) and white blood cell count X8 (r=0.238,P=0.009).Multiple linear regression equation analysis indicated that statistically significant correlation existed between the above influence factors and hospitalization time (P＜0.05).The multiple regression equation was as follows:Y=-3.438+3.055X6+0.527X7+0.297X8,F=5.819,R2=0.416.No statistically significant correlation existed between the hospitalization time and other factors,including gender,age,diabetes mellitus,pathogenic bacteria and location of abscess (P＞0.05).Conclusion Percutaneous puncturing drainage is an effective treatment for liver abscess,it carries lower mortality and lower complication rate,and its hospitalization time is short.(J Intervent Radiol,2017,
