Prospective,single-center cohort study analyzing the efcacy of complete laparoscopic resection on recurrent hepatocellular carcinoma

Background: Laparoscopic hepatectomy is increasingly being used to treat hepatocellular carcinoma (HCC). How?ever, few studies have examined the treatment of recurrent HCC in patients who received a prior hepatectomy. The present prospective study compared the clinical efcacy of laparoscopic surgery with conventional open surgery in HCC patients with postoperative tumor recurrence. Methods: We conducted a prospective study of 64 patients, all of whom had undergone open surgery once before, who were diagnosed with recurrent HCC between June 2014 and November 2014. The laparoscopic group (n = 31)underwent laparoscopic hepatectomy, and the control group (n tion time, intraoperative blood loss, surgical margins, postoperative pain scores, postoperative time until the patient= 33) underwent conventional open surgery. Opera?could walk, anal exsufation time, length of hospital stay, and inpatient costs were compared between the two groups. The patients were followed up for 1 year after surgery, and relapse?free survival was compared between the two groups. Results: All surgeries were successfully completed. No conversion to open surgery occurred in the laparoscopic group, and no serious postoperative complications occurred in either group. No significant difference in inpatient costs was found between the laparoscopic group and the control group (P = 0.079), but significant differencesbetween the two groups were observed for operation time (116.7 ± 37.5 vs. 148.2 ± 46.7 min, P = 0.031), intraopera?tive blood loss (117.5 ± 35.5 vs. 265.9 ± 70.3 mL, P = 0.012), postoperative time until the patient could walk (1.6 ± 0.6vs. 2.2 ± 0.8 days, P < 0.05), anal exsufation time (2.1 ± 0.3 vs. 2.8 ± 0.7 days, P = 0.041), visual analogue scale pain score (P < 0.05), postoperative hepatic function (P < 0.05), and length of hospital stay (4.5 ± 1.3 vs. 6.0 ± 1.2 days,P= 0.014). During the 1?year postoperative follow?up period, 6 patients in each group had recurrent HCC on the side of the initial operation, but no significant difference between groups was observed in the recurrence rate or relapse?free survival. In the laparoscopic group, operation time, postoperative time until the patient could walk, anal exsufation time, and inpatient costs were not different (P > 0.05) between the patients with contralateral HCC recur?rence (n = 18) and those with ipsilateral HCC recurrence (n = 13). However, intraoperative blood loss was signifi?cantly less (97.7 ± 14.0 vs. 186.3 ± 125.6 mL, P = 0.012) and the hospital stay was significantly shorter (4.2 ± 0.7 vs. 6.1 ± 1.7 days, P = 0.021) for the patients with contralateral recurrence than for those with ipsilateral recurrence. Conclusions: For the patients who previously underwent conventional open surgical resection of HCC, complete laparoscopic resection was safe and effective for recurrent HCC and resulted in a shorter operation time, less intraop?erative blood loss, and a faster postoperative recovery than conventional open surgery. Laparoscopic resection was especially advantageous for the patients with contralateral HCC recurrence.

Selective continuous vascular occlusion and perioperative fluid restriction in partial hepatectomy. Outcomes in 101 consecutive patients.

BACKGROUND: This study documents patient outcomes with one department's approach to performing partial hepatectomy. METHODS: 101 consecutive patients underwent: preoperative dehydration; intraoperative CVP <5 cm H(2)O and selective continuous vascular occlusion. Outcome variables: pathology; type of hepatic resection; intraoperative blood loss and transfusion rate; 30 day morbidity and mortality; disease free and long term survival. Perioperative liver function was assessed by serial blood sampling. RESULTS: Of 101 resections: 90% malignant disease; 59% major resections and 35% synchronous procedures. Median estimated blood loss was 400 mL (mean 512 mL, range 50-3000 mL) with postoperative transfusions in 4%. Thirty day morbidity was 20% with no deaths. Median time to local recurrence after colorectal liver metastases resection was 17.1 months with 3 year survival of 51%. Distinct perioperative changes in hepatic function were seen. CONCLUSION: Selective continuous vascular occlusion and perioperative fluid restriction result in minimal blood loss, low morbidity and zero mortality in patients undergoing partial hepatectomy.

Selective hepatic vascular exclusion and Pringle maneuver: A comparative study in liver resection

Objective

Most liver resections require champing of the hepatic pedicle (Pringle maneuver) to avoid excessive blood loss. But Pringle maneuver cannot control backflow bleeding of the hepatic vein. Resection of liver tumors involving hepatic veins may cause massive hemorrhage or air embolism from injuries of the hepatic vein. Although total hepatic vascular exclusion (THVE) can prevent bleeding of the hepatic vein effectively, it also may result in systemic hemodynamic disturbance because of the clamped inferior vena cava (IVC). SHVE, a new technique, can control the inflow and outflow of the liver without clamping the vena cava. We compared the effects of selective hepatic vascular exclusion (SHVE) and Pringle maneuver in resection of liver tumors involving the junction of the hepatic vein.

Methods

From January 2000 to October 2005, 2100 patients with liver tumors had undergone liver resections in our department. Among them, tumors of 235 cases adhered to or were close to the junction of one or more hepatic veins. Both SHVE and Pringle maneuver were used to control blood loss during hepatectomy. These 235 cases were divided into two groups: Pringle maneuver group (110) from January 2000 to December 2002 and SHVE group (125) from January 2003 to October 2005. Data were analyzed regarding the intraoperative and postoperative courses of the patients. In the SHVE group, total SHVE (clamping the porta hepatis and all major hepatic veins) was used in 69 cases and partial SHVE (clamping the porta hepatic and one or two hepatic veins) in 56 cases. There were three methods in hepatic veins occlusion: ligating with suture, encircling and occluding with tourniquets and clamping with Satinsky clamps.

Results

There was no difference between the two groups regarding the age, gender, tumor size, cirrhosis and HBsAg rate, ischemia time and operating time. Intraoperative blood loss and transfusion requirements were significantly decreased in the SHVE group. Hepatic veins rupture with massive blood loss occurred in 14 and air embolism in three during the tumor resection, but there was no massive blood loss and air embolism in the SHVE group due to hepatic vein occlusion. Postoperative bleeding, reoperation, liver failure and mortality rate were higher, and ICU stay and hospital stay were longer in the Pringle group than those in the SHVE group.

Conclusion

SHVE is much more effective than Pringle maneuver in controlling intraoperative bleeding. It can prevent massive blood loss and air embolism from hepatic veins rupture and can reduce the postoperative complication rate and mortality rate. Clamping the hepatic veins with Satinsky clamps is much safer and easier than ligating with suture and occluding with tourniquets.     

Radio-frequency ablation (RFA) assisted endoscopic hepatectomy for hepatocellular carcinoma

We introduced a new therapeutic approach for hepatocellular carcinoma (HCC); Radio-frequency ablation (RFA) assisted endoscopic hepatectomy (RFA-assisted EH). Seven patients with HCC, smaller than 3 cm and located on the surface of the liver, were entered into this study. RFA on the hepatic cutting line was achieved with a 2 cm Cool-tip needle at a 1-cm interval. RFA power was gradually increased to 100 W in a minute and ablation was stopped once an impedance-out state was attained of RFA power. Hepatic resection was achieved with various items in a coagulative hepatic parenchyma. If necessary, additional RFA could be performed during the hepatectomy. Patients' characteristics were described as follows; average age: 64 years, 5 males and 2 females, liver damage A: 5, B: 2, average tumor size: 27 mm, and average tumor number: 1.3 Two thoracoscopic and 5 laparoscopic approaches were selected. One application of RFA could make an elliptical coagulative area (2 cm x 1 cm). RFA was achieved eleven times on the hepatic cutting line and three times during the hepatectomy. The average operating time and blood loss was 256 minutes and 96 g, respectively. No blood product was needed. The average postoperative hospital stay was 11 days and no operative complication was encountered. All of the patients were well and without recurrence during the observation period (average: 6 months). We positively recommend RFA-assisted EH for HCC due to its perfect radicality and safety.     

不同肝血流阻断方法对可手术小肝癌预后的影响

目的 比较可手术小肝癌选择性适时半肝血流阻断法与肝十二指肠韧带阻断法（Pringle法）对患者中长期生存的影响。方法 根据肝血流阻断不同方式,将我院腹部外科222例小肝癌手术患者分为无肝门阻断、选择性适时半肝血流阻断与Pringle法3组,对以上患者进行随访,收集生存资料进行分析比较。结果 选择性适时半肝血流阻断组与无肝门阻断和Pringle法组患者之间中位生存时间差异有统计学意义（P值分别为0.02、0.04）。无肝门阻断、选择性适时半肝血流阻断和Pringle法组患者3年生存率分别为81.3%、93.3%和76.0%,三者间差异有统计学意义（P=0.008）;5年生存率分别为70.6%、90.8%和50.7%,三者间差异有统计学意义（P<0.001）。选择性适时半肝血流阻断组3年生存率与5年生存率均优于其他两组。结论 在小肝癌可手术患者中应用选择性适时半肝血流阻断较Pringle法能显著延长患者的生存时间,提高患者生存率。     

微波固化针在不规则肝脏切除治疗肝癌中的应用

目的:探讨微波固化针在不规则肝脏切除术中的应用价值.方法:回顾性分析我科2011年9月至2013年9月联合微波固化针所施行的68例不规则性肝切除患者的临床资料(微波固化+不规则性肝切除组,A组),与肝切除数据库中同样行不规则肝切除患者进行配对(单纯不规则切除组,B组),并对两组对比分析.结果:两组围手术期均无死亡病例.微波固化在不规则肝脏切除术中无需行肝门阻断,手术时间、出血量、补血量、术后住院时间明显少于单纯行不规则性肝切除术,术后并发症少,恢复快(P＜0.05).而术后肝功能恢复情况两组并无显著差异(P＞0.05).结论:微波固化针在不规则性肝切除术中的应用是安全有效的.在掌握传统方法阻断肝门切肝的基础上,使用微波固化针沿预切除线行微波固化带,可显著减少手术出血量,缩短肝门部阻断及总体时间,且患者术后康复较快.     

控制性低中心静脉压对肝切除术患者肾功能的影响

Objective： To investigate the effects of low central venous pressure （LVCP） on blood loss and evaluate its influence on renal function in patients undergoing hepatectomy. Methods： Forty-six patients, ASA classification Ⅰ-Ⅲ, undergoing liver resection were randomized into LCVP group （n = 23） and control group （n = 23）. In LCVP group, CVP was maintained at 2-4 mmHg and MBP above 60 mmHg during hepatectomy, while in control group hepatectomy was performed routinely without lowering CVP. Volume of blood loss during hepatectomy, volume of blood transfusion, and changes of renal functions were compared between the two groups. Results： There were no significant differences in demographics, ASA score, type of hepatectomy, duration of inflow occlusion, operation time, weight of resected liver tissues, and renal functions between the two groups. LCVP group had a significantly lower volume of total intraoperative blood loss （P 〈 0.01） and RBC transfusion （P 〈 0.05）. Conclusion： Lowering the CVP to less than 5 mmHg is a simple and effective technique to reduce blood loss and blood infusion during liver resection, and has no detrimental effects on renal functions.     

Postoperative morbidity adversely impacts long-term oncologic prognosis following hepatectomy for hepatocellular carcinoma: A multicenter observational study

Background & aimsPostoperative morbidity following hepatectomy for hepatocellular carcinoma (HCC) is common and its impact on long-term oncological outcome remains unclear. This study aimed to investigate if postoperative morbidity impacts long-term survival and recurrence following hepatectomy for HCC.MethodsThe data from a multicenter Chinese database of curative-intent hepatectomy for HCC were analyzed, and independent risks of postoperative 30-day morbidity were identified. After excluding patients with postoperative early deaths (≤90 days), early (≤2 years) and late (>2 years) recurrence rates, overall survival (OS), and time-to-recurrence (TTR) were compared between patients with and without postoperative morbidity.ResultsAmong 2,161 patients eligible for the study, 758 (35.1%) had postoperative 30-day morbidity. Multivariable logistic regression analysis showed that diabetes mellitus, obesity, Child-Pugh grade B, cirrhosis, and intraoperative blood transfusion were independent risks of postoperative morbidity. The rates of early and late recurrence among patients with postoperative morbidity were higher than those without (50.7% vs. 38.8%, P < 0.001; and 41.7% vs. 34.1%, P = 0.017). Postoperative morbidity was associated with decreased OS (median: 48.1 vs. 91.6 months, P < 0.001) and TTR (median: 19.8 vs. 46.1 months; P < 0.001). After adjustment of confounding factors, multivariable Cox-regression analyses revealed that postoperative morbidity was associated with a 27.8% and 18.7% greater likelihood of mortality (hazard ratio 1.278; 95% confidence interval: 1.126–1.451; P < 0.001) and recurrence (1.187; 1.058–1.331; P = 0.004).ConclusionThis large multicenter study provides strong evidence that postoperative morbidity adversely impacts long-term oncologic prognosis after hepatectomy for HCC. The prevention and management of postoperative morbidity may be oncologically important.     

肝癌首发部位对患者术后复发的影响

目的探讨肝癌首发部位及联合血清甲胎蛋白(AFP)表达对于预测肝癌患者术后复发及预后的意义。方法回顾性分析2005年3月-2009年10月行肝癌手术并长期随访的256例患者,运用Kaplan-Meier生存曲线分析总体生存率及术后复发率,Logrank检验P值,Cox比例风险模型进行单因素及多因素分析术后复发高危因素。结果肝癌首发部位不同,其术后总体生存率差异有统计学意义(P=0.022),且肝癌首发于全肝或肝左叶组患者较肝右叶组患者具有更高的术后复发风险(P=0.002)。分层分析发现,在AFP阴性(AFP<25 ng/ml)亚组中两者术后复发率差异有统计学意义(P<0.001)。Cox单因素及多因素分析显示远处转移(P=0.016)、血清AFP(P=0.002)及门脉癌栓(P<0.001)可以作为预测肝癌术后复发的独立危险因素,而肝癌首发部位不能作为一个独立的危险因素(P=0.088)。结论肝癌首发部位可以作为一个预测患者术后复发的危险因素。     

Continuous improvements in short and long-term outcomes after partial hepatectomy for hepatocellular carcinoma in the 21st century: Single institution experience with 1300 resections over 18 years

IntroductionTo investigate the changing trends in short- and long-term outcomes after partial hepatectomy(PH) for hepatocellular carcinoma(HCC) performed in the 21st century.MethodsA retrospective review was conducted on 1300 consecutive patients who underwent PH for HCC. The study cohort was divided into 3 time periods(P): P1(2000–2005), P2(2006–2011) and P3(20012-2017).ResultsComparison between the patients’ baseline demographic features across the 3 periods demonstrated that patients were significantly older, had decreasing frequency of hepatitis B, increasing non-alcoholic fatty liver disease, lower alpha-feto protein(AFP) level, lower creatinine levels, less likely to undergo emergency surgery, less likely to undergo major hepatectomy, more likely to undergo repeat resection and minimally-invasive surgery. There was also an increase in operation time, decrease in blood loss, increase frequency in the use of Pringles manoeuvre, decrease liver failure, decrease length of stay and decrease postoperative mortality. HCC resected were of smaller size, less likely to demonstrate microvascular invasion and less likely to have close margins. This was associated with significant improvement in overall survival and recurrence free interval over time. Period of resection was an independent predictor of 90-day mortality and OS on multivariate analysis.ConclusionWe observed a continuous improvement in postoperative outcomes including postoperative mortality and long-term survival after PH for HCC over the past 18 years.     

Tissue preserving hepatectomy by a vessel sealing device

BACKGROUND: The intraoperative blood loss and the biliary leak constitute the major causes of postoperative morbidity following liver resection. We describe a new technique for liver parenchyma transection using the Atlas modification of the ligasure vessel sealing system. The gradual closure of the instrument may cause crushing of the hepatic tissue and heat sealing of the vessels and bile ducts at the same time. MATERIALS AND METHODS: Ten cirrhotic patients (group A) underwent minor liver resections due to hepatocellular carcinoma (HCC). In four of these patients a bisegmentectomy was carried out, whereas in the remaining six the resection involved one segment. In addition, twelve patients with localized metastatic liver disease (group B) underwent tissue preserving hepatectomy also. Six of these patients underwent a bisegmentectomy and six had a local resection involving one segment. RESULTS: The blood loss in the first group varied from 120 to 350 ml, whereas in the second group varied from 80 to 280 ml. No postoperative biliary leakage was mentioned. CONCLUSION: This alternative technique of dividing the hepatic parenchyma seems to be simple and efficacious in preventing significant blood loss and bile leak in minor liver resections.     

Management of spontaneous rupture of hepatocellular carcinoma: single-center experience.

PURPOSE: To report the management of patients with spontaneous rupture of hepatocellular carcinoma (HCC) in a single center over a 10-year period and to evaluate a two-stage therapeutic approach. PATIENTS AND METHODS: A retrospective study was performed on all 1,716 patients with HCC who presented from 1989 to 1998. The two-stage therapeutic approach to manage ruptured HCC consisted of initial management by conservative method, hemostasis by transarterial embolization (TAE) or surgical means, followed by second-stage hepatic resection or transarterial oily chemoembolization (TOCE). Results of definitive treatment were compared with patients with no history of rupture during the same study period. RESULTS: During the study period, 154 patients (9%) had spontaneous HCC rupture. Initial intervention to control bleeding included TAE in 42 patients, surgical hemostasis in 35 patients, and conservative management only in 53 patients. The 30-day mortality rate was 38%. Independent factors on presentation affecting 30-day mortality were shock on admission, hemoglobin, serum total bilirubin, and known diagnosis of inoperable tumor. After initial stabilization and clinical evaluation, 33 patients underwent hepatic resection and 30 patients received TOCE. Median survival of the hepatectomy patients was 25.7 months; that of the TOCE patients was 9.7 months. Compared with patients with no rupture, survival after hepatectomy (25.7 months v 49.2 months, P =.003) was inferior but still substantially long, whereas survival after TOCE was comparable (9.7 months v 8.7 months, P =.904). CONCLUSION: Early mortality of spontaneous rupture of HCC was dependent on prerupture disease state, liver function, and severity of bleeding. Although it was a catastrophic presentation, prolonged survival could be achieved in selected patients with second-stage hepatic resection or TOCE.

Left jackknife position: a novel position for laparoscopic hepatectomy

Background:Laparoscopic hepatectomy for hepatocellular carcinoma (HCC) located in segment Ⅵ,Ⅶ,or Ⅷ of the liver is usually difficult because of poor operative exposure,due to the unique anatomical structure.In this study,we evaluated the practice of laparoscopic hepatectomy with the left jackknife position for patients with HCC located in segment Ⅵ,Ⅶ,or Ⅷ.Methods:A total of 10 patients were enrolled to undergo laparoscopic hepatectomy with the left jackknife position.Tumors located in segment Ⅵ,Ⅶ,or Ⅷ were assessed by preoperative dynamic computed tomography or magnetic resonance imaging.Operation time,intraoperative blood loss,postoperative fasting time,postoperative drainage time,major postoperative complications,and duration of postoperative hospital stay were recorded.Results:All surgeries were successfully completed.None of the patients required conversion to open surgery during the procedure,and no serious postoperative complications were observed.The median tumor size was 31 mm (range 23-41 mm) in diameter,the mean operation time was 166 ± 38 min,the mean intraoperative blood loss was 220 ± 135 mL,and the median postoperative hospital stay was 4 days (range 2-7 days).Conclusions:For HCC located in segment Ⅵ,Ⅶ,or Ⅷ,laparoscopic hepatectomy with this novel position—the left jackknife position—is safe and effective during tumor resection by exposing a sufficient operating field.
