肝细胞癌(HCC)根治切除后常见残余肝肿瘤早期复发。其原因之一可能是由于手术操作致瘤细胞经门脉系统多处播散的结果。为此作者设计,切除肝叶前,以淀粉微粒将门脉分支暂时栓塞,切断瘤细胞扩散的途径。此法共治疗8例 HCC 病人。男7例,女1例,平均年龄58岁。8例中有6例肝硬化,2例慢性肝炎。Child’s 肝功能不良分类:4例 A级,2例 B 级,2例 C 级。4例肿瘤位于后下次段,2例位于前下次段,2例位于前上次段。对所有病人均行肝次段切除。术中在超声导引下,以23号针穿刺荷瘤肝段门脉分支,将5～10ml 淀粉微粒混悬液(6百万微粒/ml)注入后行肝次段切除。
The early recurrence of residual liver tumors after radical resection of hepatocellular carcinoma (HCC). One of the reasons for this may be the result of multiple transmissions of tumor cells through the portal system due to surgical operations. To this end, the author designed the portal vein branch to be temporarily embolized with starch microparticles before cutting the hepatic lobe, and cut off the proliferation of tumor cells. This method treats 8 cases of HCC patients. There were 7 males and 1 female with an average age of 58 years. Of the 8 cases, 6 were cirrhosis and 2 were chronic hepatitis. Child’s liver dysfunction classification: 4 cases of A grade, 2 cases of B grade, 2 cases of C grade. Four tumors were located in the next segment, 2 were in the previous segment, and 2 were in the previous segment. All patients underwent secondary hepatectomy. Under ultrasound guidance, a 23-gauge needle was used to puncture the portal segment of the tumor-bearing liver segment and 5 to 10 ml of starch microparticle suspension (6 million microparticles/ml) was injected into the hepatic segment.
