Abstract

Abstract: The clinical data of 15 cases that planned to receive totally laparoscopic associating liver partition and portal vein ligation for staged hepatectomy were retrospectively collected. Before the stage 1 operation, the size and number of the tumors in future liver remnant (FLR) and the presence of cancer embolus in the portal vein were assessed using contrast-enhanced ultrasound (CEUS) and contrast-enhanced computed tomography (CECT). Before the stage 2 operation, CEUS was performed to assess the presence of traffic blood flow between the diseased liver and FLR after round-the-liver ligation. Before the stage 1 operation, 5 cases with tumors in FLR were found by CEUS and 6 cases were found by CECT ( P > 0.05). Similarly, CEUS found 5 cases with cancer thrombus in portal vein, and CECT found 7 cases ( P = 0.500). The consistency between the 2 modalities was good (κ = 0.857, P < 0.05, κ = 0.727, P < 0.05, respectively). Before the stage 2 operation, CEUS confirmed that there were 7 cases without traffic blood flow between the diseased liver and FLR, and 3 cases with residual traffic blood flow. The daily growth rate of FLR in the group without traffic blood flow (mean rank = 7.00) was higher than that in the group with traffic blood flow (2.00) significantly ( P < 0.05). Contrast-enhanced ultrasound is a promising application in the preoperative evaluation of totally laparoscopic associating liver partition and portal vein ligation for staged hepatectomy.

术前超声造影在全腹腔镜联合肝分区门静脉结扎在肝肿瘤分期肝切除术中的应用价值初探

摘要:回顾性收集15例拟行全腹腔镜联合肝分区门静脉结扎行分期肝切除术的临床资料。在一期手术前，使用超声造影(CEUS)和计算机断层造影(CECT)评估未来肝残体(FLR)肿瘤的大小和数量以及门静脉是否存在癌栓。2期手术前，行超声造影评估围肝结扎后病变肝脏与FLR之间是否存在交通血流。一期术前超声造影发现FLR肿瘤5例，CECT发现6例(P > 0.05)。同样，CEUS发现门静脉癌栓5例，CECT发现门静脉癌栓7例(P = 0.500)。两种模式的一致性较好(κ = 0.857, P < 0.05， κ = 0.727, P < 0.05)。二期手术前超声造影证实病变肝与FLR间无交通血流7例，交通血流残余3例。无交通血流组FLR日生长率(平均rank = 7.00)显著高于有交通血流组(平均rank = 2.00) (P < 0.05)。超声造影在全腹腔镜联合肝分区及门静脉结扎术分期肝切除术的术前评价中有很好的应用前景。
