Analysis of therapeutic efficacy and treatment model of interventional treatment in hepatic hemangiomas with poor blood supply / 中华消化杂志

ABSTRACT

Objective To analyze the efficacy and complications of interventional treatment in hepatic hemangiomas with poor blood supply,and to explore the mode of treatment.Methods From May 2013 to October 2016,at Tianjin Third Central Hospital,82 patients with hepatic hemangiomas with poor blood supply were enrolled and divided into intervention group,puncture group and combination group.Conventional hepatic artery intubation was performed in intervention group,using a microcatheter to superselect to hemangioma and injecting pingyangmycin-lipiodol emulsion into the tumor of hemangioma.Patients of puncture group underwent the ultrasound-guided percutaneous liver puncture,and the pingyangmycin-lipiodol emulsion was injected into the tumor.The patients of combination group first received intervention treatment,and the pingyangmycin-lipiodol emulsion were injected again into the tumor area lacking of iodized oil deposition through percutaneous transhepatic puncture.After treatment,the complications and clinical efficacy of patients in three groups were evaluated and the reasons of patients lost to follow-up were analyzed.The analysis of variance,Chi-square test and Fisher's exact test were performed for statistical analysis.For patients lost to follow up,intention-to-treat (ITT) analysis and per protocol (PP) analysis were used.Results Among 82 patients with hepatic hemangiomas with poor blood supply,there were 27 in intervention group,24 in puncture group and 31 in combination group.Seven patients developed serious complications such as liver failure.At three months after the treatment,the overall efficacy of combination group (20.9％,9/31) was higher than that of intervention group (7.4％,2/27) and puncture group (4.2 ％,1/24),and the differences were statistically significant (x2 =6.296,P =0.014;x2 =5.622,P =0.031).At six months after the treatment,the overall efficacy of combination group (ITT analysis 70.3 ％,26/37;PP analysis 71.0 ％,22/31) was still higher than that of intervention group (40.9％,9/22) and puncture group (7/18),and the differences were statistically significant (ITT analysis x2 =4.929 and 4.969,PP analysis x2 =4.789 and 4.851;all P＜0.05).At twelve months after the treatment,a total of 41 patients of three group were lost.Among them,the patients with ineffective treatment by clinical effect evaluation accounted for 63.4％ (26/41),which was higher than those with significantly effective treatment (12.2 ％,5/41) and those with effective treatment (24.4 ％,10/41),and the differences were statistically significant (x2=22.873 and 12.676,both P＜0.01).Conclusions The efficacy of the interventional treatment alone for hepatic hemangiomas with poor blood supply is poor and the complications should be considered when selecting the appropriate treatment methods.
