肝癌肝切除手术方式的理论基础及临床价值

治愈性肝切除治疗肝癌的主要目的是切除有足够切缘的肿瘤,同时亦保留足够的余肝体积和功能以支持病人快速康复。近年来,肝脏外科发展迅速,新的切肝技术涌现。概括而言,肝切除手术仅有5个操作步骤,即：（1）分离韧带和游离肝脏。（2）阻断第一肝门的有关分支,即阻断有关切除肝脏部分的入肝血流及胆管。（3）阻断第三肝门的肝短静脉。（4）阻断第二肝门的有关肝静脉。（3）+（4）等同于阻断有关切除肝脏部分的出肝血流。（5）离断肝实质。此外,在关腹前须彻底止血清洗。不同肝切除方法以不同的顺序联合上述5个步骤。部分肝切除可分为解剖性与非解剖性肝切除。理论上,解剖性肝切除比非解剖性肝切除的优点多。因此,非解剖性肝切除只应施行在肿瘤位于数个肝段的交界处,或肿瘤较小并且位于肝脏周边的病人。解剖性肝切除是基于肝内解剖,将肝脏分为两个半肝,4个肝区（或扇区）和8个肝段。解剖性肝切除是根据肝内解剖平面进行,故出血较少且余肝功能较好。手术可在术前或术中计划,而且手术可遵循肿瘤学的原则进行。解剖性肝切除可采取以下方法进行：（1）基于肝脏表面解剖学标志和使用术中超声引导。（2）首先控制Glisson肝蒂供应准备切除的肝段。（3）术中超声引导穿刺供应将要切除肝段的门静脉分支,并注入染料。（4）使用球囊导管通过肠系膜上静脉的属支进行性阻断门静脉或注入染料。最新的三维可视化技术在肝脏领域的应用,使解剖性肝切除手术在术前可进行更好地规划。

The Clinical Study of Precise Hemihepatectomy Guided by Middle Hepatic Vein

Objective

This study was designed to analyze the feasibility of classification for hepatic veins preoperatively and to evaluate the safety and therapeutic efficacy of precise hemihepatectomy guided by middle hepatic vein.

Methods

Thirty patients who underwent precise hemihepatectomy (PH group) were subjected to multi-slice helical CT hepatic venography preoperatively to achieve Nakamura’s and Kawasaki’s classification of hepatic veins. The hemihepatectomy was performed precisely by the guidance of middle hepatic vein, which was revealed by the hepatic venography and confirmed with intraoperative ultrasound. The clinical data of these patients were compared with other 38 traditional hemihepatectomy patients (control group). The amount of intraoperative bleeding and blood transfusion, liver function recovery, postoperative complications, and 1-year follow-up data were compared between two groups.

Results

The ratios of Nakamura’s classification type I, II, and III of hepatic veins were 56.7?% (17/30), 26.7?% (8/30), and 16.7?% (5/30), respectively; The percentages of Kawasaki’s classification type I and II of hepatic veins were 36.7?% (11/30) and 63.3?% (19/30), respectively. The total 30 cases of precise hemihepatectomies were performed successfully, including 13 cases of right hemihepatectomy without MHV, 15 cases of left hemihepatectomy without MHV, 1 case of right hemihepatectomy with MHV, and 1 case of left hemihepatectomy with MHV. There was no significant difference in operation-related mortality, the amount of intraoperative bleeding and blood transfusion, as well as serum alanine aminotransferase, total bilirubin, and cholinesterase of the third postoperative day between the two groups. However, negative resection margin and albumin level were more favorable in precise hemihepatectomy group than control group. In addition, the incidence of postoperative pleural effusion and seroperitoneum was decreased significantly in precise hemihepatectomy group. The 1-year, tumor-free survival rate was 79?% (15/19) In PH group, which is 48?% in control group.

Conclusions

Preoperative evaluation of hepatic veins is of great value for individual operative program via determination of anatomical type of hepatic veins. Precise hemihepatectomy could preserve functional liver tissue with complete venous return to a great extent, resulting in fewer incidences of postoperative pleural effusion and seroperitoneum. Precise hemihepatectomy also has the potential to achieve more adequate tumor-free resection margin, which may result in higher tumor-free survival rate.

Disruption of the Middle Hepatic Vein is not Crucial for Liver Regeneration of the Remnant Liver After Right Hemihepatectomy for Hepatic Tumors

Background To clarify the role of the middle hepatic vein (MHV) in liver regeneration of the remnant liver after right hemihepatectomy for hepatic tumors, we reviewed 29 patients to evaluate liver regeneration for up to 12 postoperative months.Methods Volume regeneration of the remnant liver was investigated by computed tomography at 3, 6, and 12 postoperative months. The remnant liver was divided into the following three areas: the medial section (segment IV), the lateral section (segments II and III), and segment I. The patients were divided into two groups: group A (n = 17), in which the MHV was preserved in the remnant liver, and group B (n = 12), in which the MHV was removed.Results Volume regeneration of each area continued until 6 postoperative months but did not increase thereafter. On univariate analysis, differences in the volume regeneration of each area between the groups were not significant at any measured time point. Furthermore, disruption of the MHV was determined to not be crucial to the volume regeneration of any liver area on multivariate analysis. Only the resection volume (percentage) significantly affected liver regeneration of the remnant liver.Conclusions Disruption of the MHV does not decisively affect liver regeneration of remnant liver after right hemihepatectomy for hepatic tumors.     

肝中静脉导向肝切除术治疗肝细胞癌临床研究

目的 探讨以肝中静脉为导向的肝切除术治疗肝细胞癌的临床疗效。方法 回顾性分析2006年6月至2015年6月南京医科大学第一附属医院肝移植中心收治的91例行肝切除获得根治的肝癌病人的临床及随访资料。以肝中静脉的完全显露区分手术方式,分为肝中静脉导向组（30例）和传统组（61例）。早期复发定义为术后1年内肿瘤复发。采用倾向性评分匹配法进行组间1:1配对,分析不同手术方式的临床效果。结果 91例病人中,左半肝和右半肝切除分别为30例和61例,肿瘤直径为9.9（1.5～20.0）cm。病人术后生存时间为48（2～127）个月,1、3、5年的总体存活率为80.1%、58.0%、41.8%,1、3、5年无瘤存活率分别为 57.7%、37.4%、30.3%。肝中静脉导向组与传统组之间的总体存活率和无瘤存活率差异无统计学意义（P>0.05）,但传统组的肿瘤早期复发率显著高于肝中静脉导向组（P<0.05）。该结果经倾向性评分匹配分析进一步证实。对所有病人资料进行多因素分析显示,大血管侵犯和卫星灶是术后总体生存的独立预后因素,大血管侵犯是术后无瘤生存的独立预后因素,年龄、甲胎蛋白、手术方式是术后肿瘤早期复发的独立危险因素。结论 肝中静脉导向肝切除术可减少肝细胞癌根治性切除术后早期复发,但总体预后主要取决于肿瘤本身的生物学因素。

Abstract Objective To explore the clinical efficacy of middle hepatic vein (MHV)-oriented hepatectomy for treatment of hepatocellular carcinoma (HCC). Methods A retrospective analysis of the clinical and follow-up data of 91 patients??who received radical treatment by hemihepatectomy at Liver Transplantation Center??the First Affiliated Hospital of Nanjing Medical University between June 2006 and June 2015 was conducted. Surgical approaches were divided into MHV-oriented group and conventional group according to full exposure of the MHV on the dissection plane. Early recurrence was defined as tumor recurrence within the first year after surgery. One-to-one propensity score matching (PSM) analysis of the two groups was performed to investigate the clinical efficacy of different surgical approaches. Results Among the 91 patients??left and right hemihepatectomy was performed in 30 and 61 patients. Mean tumor size was 9.9 cm (1.5 to 20.0 cm). Median survival time was 48 months (2 to 127 months). The 1-??3- and 5-year overall survival (OS) rates were 80.1%??58.0%??and 41.8%??respectively. Corresponding disease-free survival (DFS) rates were 57.7%??37.4%??and 30.3%. There was no statistic difference between MHV-oriented group and conventional group in terms of OS and DFS; However??early recurrence rate in conventional group was significantly higher than that in MHV-oriented group. The result was further confirmed by PSM. Multivariate analysis of all patients showed that macrovascular invasion and satellite focus were independent prognostic factors for OS??macrovascular invasion was the independent prognostic factor for DFS??and surgical approach was an independent risk factor for early recurrence after surgery. Conclusion MHV-oriented hepatectomy is associated with decreased early recurrence after radical resection of HCC??However??tumor biology remains the main determinant of overall prognosis.

Arantius’ Ligament Approach to Middle Hepatic Vein in Laparoscopic Extended Medial Segmentectomy (with Video)

Background

Under laparoscopy-specific caudal and lateral view, Aranitius’ ligament could be the landmark for the root of the venous trunks in the left hepatic lobe.1,2,3 We performed laparoscopic hepatic extended medial segmentectomy including the middle hepatic vein (MHV) using the Arantius’ approach.

Methods

An 86-year-old man was referred to our hospital for hepatocellular carcinoma, 4.5 cm in size, located in the medial hepatic segment (Video 1). After pneumoperitoneum and placement of four working ports, the Arantius’ ligament was exposed, isolated, and divided. The liver parenchyma underneath the Arantius’ ligament was opened to widely expose the root of the MHV, umbilical fissure vein (UFV), and left hepatic vein (LHV). After dividing the Glissonean branches for segment 4 (G4), the parenchymal tissue between MHV and LHV was divided. The trunk of the MHV was fully exposed and was divided using the endo-stapling device. Parenchymal resection was further proceeded along the dorsal side of the MHV, and the planned hepatectomy was completed.

Results

The operation time was 337 min, and the estimated blood loss was 400 g. His postoperative course was uneventful, and he was discharged on postoperative day 10.

Conclusions

The significance of Arantius’ ligament approach is short-cut exposure of the MHV as the anatomical landmark during the initial process of the surgery under laparoscopy-specific caudal and lateral view, and is a reasonable technique in extended medial segmentectomy including the MHV.
