Laparoscopic left lateral sectionectomy has been proven to be a safe and effective treatment for liver lesions. However, most of the literatures only reported this treatment method on benign lesion or colorectal metastases. The data on long-term outcome of laparoscopic left lateral section resection in patients with HCC and cirrhosis are still limited. The aim of this study is to analyze the survival outcome of laparoscopic left lateral sectionectomy when compared to open approach in patients with HCCs.Between January 2004 and September 2014, 967 patients had primary HCC with hepatectomy performed. Twenty-four patients had undergone pure laparoscopic left lateral sectionectomy for hepatocellular carcinoma (HCC). Twenty-nine patients with case-matched tumor characteristics and liver functions but received open left lateral sectionectomy for HCC were included for comparison.Comparing laparoscopic group to open resection group, the median operation time was 190.5 versus 195 min (P = 0.734); the median blood loss was 100 versus 300 ml (P0.001). Hospital stay was 5 days in laparoscopic group versus 6 days in the open group (P = 0.057). There was no difference between the two groups in terms of complications (P = 0.495). The median survival in laparoscopic group was115 months versus125 months in the open group (P = 0.853).Laparoscopic left lateral sectionectomy for HCC is a safe and simple procedure associated with less blood loss. The survival outcome is comparable with conventional open approach. It is becoming a more favorable treatment option even for patients with HCC and cirrhosis.

Repeated resection via an open approach is an effective treatment for post-operative recurrent hepatocellular carcinoma (HCC). However, there are limited data on the application of laparoscopic approach for recurrent HCC in patients with prior liver resections. The aim of this study was to review our experience of laparoscopic re-resection in patients with postoperative tumor recurrence.A total of 11 patients received laparoscopic re-resections for postoperative tumor recurrence in our center. Data were reviewed for demographics, tumor characteristics, and perioperative outcomes. Case-match analysis with the open approach was performed in a 1:2 ratio.Six patients had their first liver resection carried out via the open approach and the remaining five patients received the laparoscopic approach. The recurrent tumor size was 20 mm (12-50 mm) and ten patients had a solitary recurrence. Two patients had laparoscopic left lateral sectionectomy and the remaining nine patients had sub-segmentectomies. There was no significant difference in patient characteristics, preoperative liver function, and tumor features between the laparoscopic and open groups. Perioperative blood loss was significantly reduced in the laparoscopic group (100 vs. 314 mL; p = 0.014) but the morbidity rate (18.2 vs. 4.5 %; p = 0.199) and length of hospitalization were comparable (6 vs. 5 days; p = 0.831). The 3-year overall survival rates for the laparoscopic and open groups were 60.0 and 89.3 %, respectively (p = 0.279).Our study showed that laparoscopic re-resection for recurrent HCC was feasible with satisfactory postoperative and oncological outcomes, even in patients with previous major liver resections.

Different approaches to surgical treatment of portal vein tumor thrombosis (PVTT) have been advocated. This study investigated the outcomes of different surgical approaches in hepatocellular carcinoma (HCC) patients with PVTT. We reviewed prospectively collected data for all patients who underwent hepatectomy for HCC at our hospital between December 1989 and December 2010. Patients were excluded from analysis if they had extrahepatic disease, PVTT reaching the level of the superior mesenteric vein, or hepatectomy with a positive resection margin. The remaining patients were divided into three groups for comparison: group 1, with ipsilateral PVTT resected in a hepatectomy; group 2, with PVTT extending to or beyond the portal vein bifurcation, treated by en bloc resection followed by portal vein reconstruction; group 3, with PVTT extending to or beyond the portal vein bifurcation, treated by thrombectomy. A total of 88 patients, with a median age of 54 years, were included in the analysis. Group 2 patients were younger, with a median age of 43.5 years versus 57 in group 1 and 49 in group 3 (p = 0.017). Group 1 patients had higher preoperative serum alpha-fetoprotein levels, with a median of 8,493 ng/mL versus 63.25 in group 2 and 355 in group 3 (p = 0.004), and shorter operation time, with a median of 467.5 min versus 663.5 in group 2 and 753 in group 3 (p = 0.018). No patient had thrombus in the main portal vein. Two (2.8 %) hospital deaths occurred in group 1 and one (10 %) in group 2, but none in group 3 (p = 0.440). The rates of complication in groups 1, 2, and 3 were 31.9, 50.0, and 71.4 %, respectively (p = 0.079). The median overall survival durations were 10.91, 9.4, and 8.58 months, respectively (p = 0.962), and the median disease-free survival durations were 4.21, 3.78, and 1.51 months, respectively (p = 0.363). The groups also had similar patterns of disease recurrence (intrahepatic: 33.8 vs. 28.6 vs. 40.0 %; extrahepatic: 16.9 vs. 14.3 vs. 0 %; both: 28.2 vs. 42.9 vs. 40.0 %; no recurrence: 21.1 vs. 14.3 vs. 20.0 %; p = 0.836). The three approaches have similar outcomes in terms of survival, complication, and recurrence. Effective adjuvant treatments need to be developed to counteract the high incidence of recurrence.

BACKGROUND: High-intensity focused ultrasound (HIFU) ablation is a relatively new, noninvasive way of ablation for treating hepatocellular carcinoma (HCC). Emerging evidence has shown that it is effective for the treatment of HCC, even in patients with poor liver function. There is currently no data on the safety limit of HIFU ablation in patients with cirrhosis. However, this information is vital for the selection of appropriate patients for the procedure. We analyzed HCC patients who had undergone HIFU ablation and determined the lower limit of liver function and other patient factors with which HCC patients can tolerate this treatment modality. METHODS: Preoperative variables of 100 patients who underwent HIFU ablation for HCC were analyzed to identify the risk factors in HIFU intolerance in terms of stress-induced complications. Factors that may contribute to postablation complications were compared. RESULTS: Thirteen (13 %) patients developed a total of 18 complications. Morbidity was mainly due to skin and subcutaneous tissue injuries (n = 9). Five patients had first-degree skin burn, one had second-degree skin burn, and three had third-degree skin burn. Four complications were grade 3a in the Clavien classification and 14 were below this grade. Univariate analysis showed that age (p = 0.022) was the only independent factor in HIFU intolerance. CONCLUSIONS: HIFU ablation is generally well tolerated in HCC patients with cirrhosis. It is safe for Child-Pugh A and B patients and selected Child-Pugh C patients. With this new modality, HCC patients who were deemed unsalvageable by other surgical means in the past because of simultaneous Child-Pugh B or C disease now have a new hope., published_or_final_version

Background: Tumor recurrence after resection of hepatocellular carcinoma is a common phenomenon. Re-resection and radiofrequency ablation (RFA) are good options for treating recurrent HCC. This study compared the efficacy of these two modalities in the treatment of intrahepatic HCC recurrence after hepatectomy. Methods: From January 2001 to December 2008, a total of 179 patients developed intrahepatic HCC recurrence after hepatectomy. To treat the recurrence, 29 patients underwent re-resection and 45 patients had RFA. Patient characteristics, clinicopathologic data, and survival outcomes were reviewed. Results: Child-Pugh status, time to develop first recurrence (12.2 vs. 8.7 months), and recurrent tumor size (2.1 vs. 2.1 cm) were comparable for the two groups. Time to develop a second intrahepatic recurrence after re-resection and RFA was 5.9 and 4.0 months respectively. The 1-, 3-, and 5-year disease-free survival rates were 41.4%, 24.2%, and 24.2% after re-resection and 32.2%, 12.4%, and 9.3% after RFA (p = 0.14). The 1-, 3-, and 5-year overall survival rates were 89.7%, 56.5%, and 35.2% after re-resection and 83.7%, 43.1%, and 29.1% after RFA (p = 0.48). For the second recurrence, 33.3% of patients underwent a second round of RFA and 10.0% underwent a third resection. Conclusions: The two treatment modalities attained similar survival benefits in the management of recurrent HCC after hepatectomy. The high repeatability of RFA and that it can be delivered percutaneously render it a preferred treatment option for selected patients. © 2011 The Author(s)., published_or_final_version, Springer Open Choice, 21 Feb 2012

De novo hepatocellular carcinoma (HCC) complicated by pyogenic liver abscess is rare, and the standard of care for this disease has yet been defined. This study assesses whether liver resection can be recommended as its standard treatment. This retrospective study reviewed the prospectively collected data of the 1725 patients who underwent primary liver resection for HCC at our hospital during the period from December 1989 to December 2012. Outcomes were compared between patients with and without liver abscess. Twenty-two (1.28 %) patients had HCC and liver abscess. Fourteen of them received preoperative drainage. Patients with and without abscess had similar tumor characteristics, but patients with abscess had more operative blood loss (2.2 vs. 0.8 L; p

Right hepatectomy (RH) instead of right posterior sectionectomy (RPS) is commonly performed for hepatocellular carcinoma (HCC) in cirrhotic livers located lateral to the right hepatic vein in order to ensure adequate resection margin. This potentially increased the risk of postoperative liver failure. This study aims to compare survival outcomes and surgical morbidities between RH and RPS. All patients between 2003 and 2013 with resection for solitary HCC in cirrhotic livers at segment 6/7 were reviewed. Baseline demographics, liver function, perioperative outcomes, and overall (OS) and disease-free survival (DFS) were compared between RH and RPS. Eighty-one patients were included in this study. Thirty-two patients had RH and forty-nine with RPS were selected as controls. Majority of the HCC patients (91.4 %) suffered from chronic hepatitis B. There was no significant difference in age, gender and Child-Pugh grade between the two groups. The median tumour size of RH group was 6 vs. 4 cm in the RPS group (p

At our center, living donor liver transplantation (LDLT) is the main workload supported by a strong, mature service. Deceased donor liver transplantation (DDLT) is performed but in small volume. This study aimed to review the results of a low-volume DDLT service alongside a strong LDLT service. Consecutive DDLTs for adults performed from 1991 to 2009 were reviewed. The 1st to the 50th DDLTs were categorized as Era I cases, and the rest were Era II cases. The outcomes of the DDLTs were analyzed and compared with those achieved overseas. Eras I and II consisted of 59 and 183 DDLTs, respectively. All donors were brain-dead and heart-beating with a median age of 49 years (range 7–76 years). Among the 242 DDLTS, 30.2 % were on a high-urgency basis and 15.3 % were for hepatocellular carcinoma. The patients had a median model for end-stage liver disease score of 21 (range 6–40), and most (67.8 %) were hepatitis B virus carriers. Before transplantation, 16.1 % of the patients were in the intensive care unit and 30.2 % were in the hospital. The hospital mortality rate dropped from 13.6 % (8/59) during Era I to 3.8 % (7/183) during Era II (p = 0.012). For Era I, the 1-, 3-, and 5-year survival rates were 84.7, 79.7, and 76.3 %, respectively, which improved to 92.9, 89.0 and 87.2 % for Era II (p = 0.026). The recipient survival of this series compares favorably with contemporary series. It is shown that a low-volume DDLT service alongside a strong LDLT service can have excellent results.

Background Liver regeneration that occurs after portal vein embolization (PVE) may have adverse effects on the microscopic tumor foci in the residual liver mass in patients with hepatocellular carcinoma (HCC). Methods Fifty-four HCC patients with inadequate functional residual liver volume were offered PVE during a seven-year period. Among them, 34 (63%) patients underwent curative resection. They were compared with a matched control group (n = 102) who underwent surgery without PVE. Postoperative complications, pattern of recurrence, and survival were compared between groups. Results In the PVE group, a pre-embolization functional residual liver volume of 23% (12–33.5%) improved to 34% (20–54%) (p = 0.005) at the time of surgery. When the two groups were compared, minor (PVE, 24%; control, 29%; p = 0.651) and major (PVE, 18%; control, 15%; p = 0.784) complications were similar. After a follow-up period of 35 months (standard deviation 25 months), extrahepatic recurrences were detected in 10 PVE patients (29%) and 41 control patients (40%) (p = 0.310). Intrahepatic recurrences were seen in 10 (29%) and 47 (46%) cases (p = 0.109) in the PVE and control groups, respectively. In the PVE group, 41% (n = 14) of the recurrences were detected before one year, compared with 42% (n = 43) in the control group (p = 1). Disease-free survival rates at 1, 3, and 5 years were 57, 29, and 26% in the control group and 60, 42, and 42% in the PVE group (log-rank, p = 0.335). On multivariate analysis, PVE was not a factor affecting survival (p = 0.821). Conclusions Portal vein embolization increases the resectability of initially unresectable HCC due to inadequate functional residual liver volume, and it has no deleterious oncological effect after major resection of HCC.
