Major liver resections for hepatocellular carcinoma on cirrhosis: Early and long-term outcomes

Lorenzo Capussotti
Since the lack of donors, liver resections continue to be the treatment of choice for cirrhotic patients with good liver function and resectable hepatocellular carcinoma (HCC). Moreover, over the past 2 decades, an increasing number of major hepatic resections have been performed. The aim of this study is to evaluate short- and long-term outcomes of 55 cirrhotic patients undergoing major hepatic resection with particular attention to the survival of the patients with gross portal vein invasion or large size tumors. Twenty-two patients (40%) required intra- or post-operative blood transfusion. Medium tumor size was 66.6±29.2 mm; 7 patients had large size (> 10 cm) HCCs. A single node was present in 38 cases (69.1%). There was a gross portal vein tumor thrombus (PVTT) in 13 patients (23.6%). Resection was non-curative in 4 cases. In-hospital mortality and morbidity rates were 5.5% and 30.9%, respectively. The overall and disease-free survival rates were 36.2% and 42.8%, respectively. Overall 5-year survival rates of patients with large size tumors was 17.1%. Ten patients with a gross PVTT had an R0 resection with a 26.6% 5-year survival rate. In conclusion, major hepatic resections for HCC can be performed with low mortality and morbidity rates. HCCs with PVTT or greater than 10 cm in size have very limited options of treatment; the favorable long-term results of our study suggest that they should undergo surgery if a radical resection can be achieved.

Cholangiocarcinoma: preoperative biliary drainage (Con)

HPB, Issue 2 2008
Aim. In patients with malignant hilar obstruction, liver resection is associated with an increased risk of postoperative liver failure attributed to the need for major liver resection in a context of obstructive jaundice. To overcome this issue, most authors recommend preoperative biliary drainage (PBD). However, PBD carries risks of its own, including, primarily, sepsis and, more rarely, tumor seeding, bile peritonitis, and hemobilia. We, unlike most authors, have not used routine PBD before liver resection in jaundiced patients. Material and methods. Our series includes 62 patients who underwent major liver resection for cholangiocarcinoma; 33 of these had elevated bilurubin (60,470 µmol/l) and were operated without PBD. There were 43 extended right hepatectomies and 18 extended left hepatectomies. Results. Hospital deaths occurred in 5 patients (8%) including 3 of 33 jaundiced patients (9%, ns). All deaths occurred after extended right hepatectomy (12%), including 3 patients with a serum bilirubin level above 300 µmol/l and 2 with normal bilirubin. There were no deaths after left-sided resections, whatever the level of bilirubin. Conclusions. PBD can be omitted in the following situations: recent onset jaundice (<2,3 weeks), total bilirubin <200 µmol/l, no previous endoscopic or transhepatic cholangiography, absence of sepsis, future liver remnant >40%. These criteria include most patients requiring left-sided resections and selected patients requiring right-sided resections. In other cases, PBD is required, associated with portal vein embolization in the event of a small future liver remnant. [source]

Complex liver resection for a large intrahepatic cholangiocarcinoma in a Jehovah's witness: A strategy to avoid transfusion

FRCS, Omar Barakat MD
Abstract Although morbidity and mortality after liver resection have improved over the last two decades, complex liver resections still require perioperative blood transfusions. In this report, we describe the use of a combined left trisegmentectomy and caudate lobectomy, along with resection of the inferior vena cava, to treat a large intrahepatic cholangiocarcinoma in a Jehovah's Witness. To our knowledge, this is the first report of major liver resection for a large malignant tumor in this patient population. We also discuss the perioperative strategy and surgical technique we used to minimize blood loss and avoid transfusion. This approach could be a safe alternative for use in all patients with complex liver tumor, regardless of their religious beliefs, to reduce the risks and cost associated with blood transfusion. J.

The small remnant liver after major liver resection: How common and how relevant?

Cengizhan Yigitler
The maximum extent of hepatic resection compatible with a safe postoperative outcome is unknown. The study goal was to determine the incidence and impact of a small remnant liver volume after major liver resection in patients with normal liver parenchyma. Among 265 major hepatectomies performed at our institution (1998 to 2000), 138 patients with normal liver and a remnant liver volume (RLV) systematically calculated from the ratio of RLV to functional liver volume (FLV) were studied. Patients were divided into five groups based on RLV-FLV ratio from ,30% to ,60%. Kinetics of postoperative liver function tests were correlated with RLV. Postoperative complications were stratified by RLV-FLV ratios. Ninety patients (65%) underwent resection of up to four Couinaud segments. The RLV-FLV ratio was ,60% in 94 patients (68%) including only 13 (9%) with RLV-FLV ,30%. There was no linear correlation between the number of resected segments and the RLV-FLV. Postoperative serum bilirubin but not prothrombin time correlated with extent of resection. The incidence of complications including liver failure was not different among groups. Analysis of the four groups with a RLV-FLV ratio <60% showed a trend toward more complications and a longer intensive care unit stay in patients with the smallest RLVs. After major hepatectomy in patients with normal livers, the proportion of patients with a small remnant liver is low and not directly related to the number of segments resected. Although the rate of postoperative complications, including liver failure, did not directly correlate with the volume of remaining liver, the postoperative course was more difficult for patients with smaller remnants. Therefore preoperative portal vein embolization should be considered in patients who will undergo extended liver resection who have (1) injured liver or (2) normal liver when the planned procedure will be complex or when the anticipated RLV-FLV will be <30%.

Major hepatectomy in patients with synchronous colorectal liver metastases: whether or not a contraindication to simultaneous colorectal and liver resection?

E. Jovine
Abstract Objective, Synchronous hepatic lesions account for 15,25% of newly diagnosed colorectal cancer and its optimal timing to surgery is not completely defined, but simultaneous colorectal and liver resection is recently gaining acceptance, at least in patients with a right colonic primary and liver metastases that need a minor hepatectomy to be fully resected. Method, From September 2002 to December 2004, 16 patients underwent simultaneous resection as treatment of synchronous colorectal liver resection; in 10 patients (62.5%) a major hepatectomy was performed. Results, The mean duration of intervention was 322.5 ± 59.5 min, operative mortality and morbidity rates was 0% and 25% respectively; the hospitalization was 14.4 (range 8,60) days on average. Mean follow-up was 14 months and actuarial survival was 76.5% at 1 year and 63.5% at 2 years. Conclusion, We concluded that simultaneous colonic and liver resection should be undertaken in selected patients with synchronous colorectal liver resection regardless of the extent of hepatectomy; major liver resection, in fact, seems capable of providing better oncological results, allowing resection of liver micrometastases that, in almost one-third of the patients, are located in the same liver lobe of macroscopic lesions, without increased morbidity rates.

Radiofrequency ablation-assisted liver resection: review of the literature and our experience

HPB, Issue 4 2006
Peng Yao
Abstract Background: Surgical resection is the best established treatment known to provide long-term survival and possibility of cure for liver malignancy. Intraoperative blood loss has been the major concern during major liver resections, and mortality and morbidity of surgery are clearly associated with the amount of blood loss. Different techniques have been developed to minimize intraoperative blood loss during liver resection. The radiofrequency ablation (RFA) technique has been used widely in the treatment of unresectable liver tumors. This review concentrates on the use of RFA to provide an avascular liver resection plane. Methods and results: The following review is based on two types of RFA device during liver resection: single needle probe RFA and the In-Line RFA device. Conclusion: Liver resection assisted by RFA is safe and is associated with very limited blood loss. [source]

Liver failure following partial hepatectomy

HPB, Issue 3 2006
Thomas S. Helling
Abstract While major liver resections have become increasingly safe due to better understanding of anatomy and refinement of operative techniques, liver failure following partial hepatectomy still occurs from time to time and remains incompletely understood. Observationally, certain high-risk circumstances exist, namely, massive resection with small liver remnants, preexisting liver disease, and advancing age, where liver failure is more likely to happen. Upon review of available clinical and experimental studies, an interplay of factors such as impaired regeneration, oxidative stress, preferential triggering of apoptotic pathways, decreased oxygen availability, heightened energy-dependent metabolic demands, and energy-consuming inflammatory stimuli work to produce failing hepatocellular functions.
