ABSTRACT

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,

ABSTRACT

Objective To summarize the risk factors, the diagnostic and therapeutic approaches, and the outcomes of the ruptured primary hepatocellular carcinoma (PHC) occurred after transcatheter arterial chemoembolization (TACE) in order to make a further understanding of this complication. Methods The clinical data of 8 patients with ruptured PHC after TACE, who were encountered at the First Affiliated Hospital of Suzhou University during the period from Sep. 2007 to Sep. 2013, were retrospectively analyzed. Results A total of 1379 times of TACE were performed in 678 patients with PHC. Among the 678 patients, 8 developed rupture of PHC with bleeding after TACE. The overall incidence was 1.2%. The mean diameter of the tumors in the 8 patients was (11.5 ± 2.6) cm, ranging from 7.6 cm to 15.9 cm. All the lesions were located at the peripheral region close to the liver capsule, and most of them protruded outward. Five cases had coexisting portal hypertension. The average dosage of Lipiodol used in TACE was (14.9 ± 4.5) ml with a range of (8 - 20) ml. Of the 8 patients, emergency transcatheter embolization was carried out in 4 and medical management was employed in other 4. Seven patients died as all active emergency treatments failed. Only one patient, who had received emergency transcatheter embolization, survived the ruptured PHC. Conclusion Rupture of primary hepatocellular carcinoma after TACE is a rare, but very serious complication. Its occurrence may be related to lesion’s characteristics, such as large tumor size, superficial location and protrusion from the liver surface, etc. Besides, interventional management, e.g. without use of solid embolic material to enhance the embolization effect, may also be responsible for the rupture.
