Endoscopic injection sclerotherapy vs. endoscopic variceal ligation in arresting acute variceal bleeding for patients with advanced hepatocellular carcinoma

Treatment for bleeding oesophageal varices in people with decompensated liver cirrhosis: a network meta-analysis

BACKGROUND

Approximately 40% to 95% of people with liver cirrhosis have oesophageal varices. About 15% to 20% of oesophageal varices bleed within about one to three years after diagnosis. Several different treatments are available, including, among others, endoscopic sclerotherapy, variceal band ligation, somatostatin analogues, vasopressin analogues, and balloon tamponade. However, there is uncertainty surrounding the individual and relative benefits and harms of these treatments.

OBJECTIVES

To compare the benefits and harms of different initial treatments for variceal bleeding from oesophageal varices in adults with decompensated liver cirrhosis, through a network meta-analysis; and to generate rankings of the different treatments for acute bleeding oesophageal varices, according to their benefits and harms.

SEARCH METHODS

We searched CENTRAL, MEDLINE, Embase, Science Citation Index Expanded, World Health Organization International Clinical Trials Registry Platform, and trials registers until 17 December 2019, to identify randomised clinical trials (RCTs) in people with cirrhosis and acute bleeding from oesophageal varices.

SELECTION CRITERIA

We included only RCTs (irrespective of language, blinding, or status) in adults with cirrhosis and acutely bleeding oesophageal varices. We excluded RCTs in which participants had bleeding only from gastric varices, those who failed previous treatment (refractory bleeding), those in whom initial haemostasis was achieved before inclusion into the trial, and those who had previously undergone liver transplantation.

DATA COLLECTION AND ANALYSIS

We performed a network meta-analysis with OpenBUGS software, using Bayesian methods, and calculated the differences in treatments using odds ratios (OR) and rate ratios with 95% credible intervals (CrI) based on an available-case analysis, according to National Institute of Health and Care Excellence Decision Support Unit guidance. We performed also the direct comparisons from RCTs using the same codes and the same technical details.

MAIN RESULTS

We included a total of 52 RCTs (4580 participants) in the review. Forty-eight trials (4042 participants) were included in one or more comparisons in the review. The trials that provided the information included people with cirrhosis due to varied aetiologies and those with and without a previous history of bleeding. We included outcomes assessed up to six weeks. All trials were at high risk of bias. A total of 19 interventions were compared in the trials (sclerotherapy, somatostatin analogues, vasopressin analogues, sclerotherapy plus somatostatin analogues, variceal band ligation, balloon tamponade, somatostatin analogues plus variceal band ligation, nitrates plus vasopressin analogues, no active intervention, sclerotherapy plus variceal band ligation, balloon tamponade plus sclerotherapy, balloon tamponade plus somatostatin analogues, balloon tamponade plus vasopressin analogues, variceal band ligation plus vasopressin analogues, balloon tamponade plus nitrates plus vasopressin analogues, balloon tamponade plus variceal band ligation, portocaval shunt, sclerotherapy plus transjugular intrahepatic portosystemic shunt (TIPS), and sclerotherapy plus vasopressin analogues). We have reported the effect estimates for the primary and secondary outcomes when there was evidence of differences between the interventions against the reference treatment of sclerotherapy, but reported the other results of the primary and secondary outcomes versus the reference treatment of sclerotherapy without the effect estimates when there was no evidence of differences in order to provide a concise summary of the results. Overall, 15.8% of the trial participants who received the reference treatment of sclerotherapy (chosen because this was the commonest treatment compared in the trials) died during the follow-up periods, which ranged from three days to six weeks. Based on moderate-certainty evidence, somatostatin analogues alone had higher mortality than sclerotherapy (OR 1.57, 95% CrI 1.04 to 2.41; network estimate; direct comparison: 4 trials; 353 participants) and vasopressin analogues alone had higher mortality than sclerotherapy (OR 1.70, 95% CrI 1.13 to 2.62; network estimate; direct comparison: 2 trials; 438 participants). None of the trials reported health-related quality of life. Based on low-certainty evidence, a higher proportion of people receiving balloon tamponade plus sclerotherapy had more serious adverse events than those receiving only sclerotherapy (OR 4.23, 95% CrI 1.22 to 17.80; direct estimate; 1 RCT; 60 participants). Based on moderate-certainty evidence, people receiving vasopressin analogues alone and those receiving variceal band ligation had fewer adverse events than those receiving only sclerotherapy (rate ratio 0.59, 95% CrI 0.35 to 0.96; network estimate; direct comparison: 1 RCT; 219 participants; and rate ratio 0.40, 95% CrI 0.21 to 0.74; network estimate; direct comparison: 1 RCT; 77 participants; respectively). Based on low-certainty evidence, the proportion of people who developed symptomatic rebleed was smaller in people who received sclerotherapy plus somatostatin analogues than those receiving only sclerotherapy (OR 0.21, 95% CrI 0.03 to 0.94; direct estimate; 1 RCT; 105 participants). The evidence suggests considerable uncertainty about the effect of the interventions in the remaining comparisons where sclerotherapy was the control intervention.

AUTHORS' CONCLUSIONS

Based on moderate-certainty evidence, somatostatin analogues alone and vasopressin analogues alone (with supportive therapy) probably result in increased mortality, compared to endoscopic sclerotherapy. Based on moderate-certainty evidence, vasopressin analogues alone and band ligation alone probably result in fewer adverse events compared to endoscopic sclerotherapy. Based on low-certainty evidence, balloon tamponade plus sclerotherapy may result in large increases in serious adverse events compared to sclerotherapy. Based on low-certainty evidence, sclerotherapy plus somatostatin analogues may result in large decreases in symptomatic rebleed compared to sclerotherapy. In the remaining comparisons, the evidence indicates considerable uncertainty about the effects of the interventions, compared to sclerotherapy.

Endoscopic ultrasound-guided cyanoacrylate injection to prevent rebleeding in hepatocellular carcinoma patients with variceal hemorrhage

BACKGROUND AND AIM

Secondary prophylaxis (SP) of variceal rebleeding was reported to improve outcomes of hepatocellular carcinoma (HCC) patients, but the optimal endoscopic approach is not well defined. We compared outcomes in HCC patients who underwent SP by endoscopic ultrasound-guided cyanoacrylate obturation (EUS-CYA) versus no SP.

METHODS

Between 2014 and 2018, 30 consecutive patients with inoperable HCC and recent endoscopically controlled variceal bleeding were prospectively recruited. Twenty-seven patients with persistent varices ≥ 3 mm on endoscopic ultrasound underwent EUS-CYA for SP. Thirty-three HCC patients treated by esophagogastroduodenoscopy-guided CYA obturation (EGD-CYA) alone for acute variceal bleeding between 2009 and 2013 were identified from a prospective gastrointestinal bleed registry as standard of care controls for comparison. Outcome measures were death-adjusted cumulative incidence of rebleeding, bleeding-free survival, technical success, and procedure-related adverse events of EUS-CYA.

RESULTS

The majority of patients in both groups had advanced HCC, portal vein thrombosis, and Child-Pugh B cirrhosis. EUS-CYA was successful in all 27 patients with no radiographic evidence of cyanoacrylate-lipiodol embolization. Significantly lower 30- and 90-day death-adjusted cumulative incidence of rebleeding (14.8% vs 42.4%, P = 0.023 and 18.5% vs 60.6%, P = 0.002, respectively) and significantly higher variceal bleeding-free survival at 3 and 6 months (51.9% vs 21.2%, P = 0.009, 40.7% vs 15.2%, P = 0.010, respectively) were observed in the EUS-CYA group when compared with standard of care group.

CONCLUSIONS

Secondary prophylaxis by EUS-CYA reduced rebleeding rate and improved variceal bleeding-free survival in patients with inoperable HCC and variceal bleeding when compared with no SP. Randomized studies are needed to confirm the benefits of EUS-CYA for this difficult-to-treat population.

Hemothorax following Uncomplicated Endoscopic Variceal Sclerotherapy and Ligation for Esophageal Varices

Endoscopic variceal sclerotherapy and ligation are standard treatment modalities used for the management of esophageal varices. Reportedly, sclerotherapy and ligation are associated with complications such as hematuria, pulmonary thrombus formation, pleural effusion, renal dysfunction, and esophageal stenosis. However, hemothorax following sclerotherapy and ligation has not yet been reported. We treated a patient who presented with liver cirrhosis and polycythemia vera and later developed hemothorax following the above-mentioned procedures. An 86-year-old man diagnosed with liver cirrhosis due to chronic hepatitis type B and alcohol abuse underwent variceal sclerotherapy using ethanolamine oleate to treat his esophageal varices. Oozing from the esophageal varices continued even after the sclerotherapy procedure; therefore, we performed endoscopic variceal ligation. The patient developed left-sided hemothorax within 24 h after treatment of his varices, and an emergency thoracotomy was performed. A pulmonary ligament of the left lung was bulging and ripping because of mediastinal hematoma, and oozing was noted. Cessation of bleeding was noted after the laceration of the left pulmonary ligament had been sutured. Ours is the first case of hemothorax reported in a patient following an uncomplicated procedure of sclerotherapy and ligation.

Endoscopic management of esophagogastric varices in Japan

Esophagogastric varices are the most common complication in patients with portal hypertension, and endoscopy plays an important role in their diagnosis and in the prevention of acute bleeding from these structures. Recently, new modalities such as endoscopic ultrasonography (EUS) and narrow-band imaging have been introduced for the diagnosis of esophagogastric varices. In Japan, endoscopic therapy has become the first choice for the treatment of acutely bleeding esophageal or gastric varices. The two principal methods used to treat esophageal varices are endoscopic injection sclerotherapy (EIS) and endoscopic variceal ligation (EVL). Recently, combinations of EIS plus EVL and EVL plus argon plasma coagulation were reported to be more effective than EVL or EIS alone. Additionally, endoscopic cyanoacrylate injection is superior to EIS and EVL for the treatment of acutely bleeding gastric varices.

Latin American Association for the Study of the Liver (LAASL) clinical practice guidelines: management of hepatocellular carcinoma

Hepatocellular carcinoma (HCC) is the fifth most common cancer in the world and the third most common cause of cancer death, and accounts for 5.6% of all cancers. Nearly 82% of the approximately 550,000 liver cancer deaths each year occur in Asia. In some regions, cancer-related death from HCC is second only to lung cancer. The incidence and mortality of HCC are increasing in America countries as a result of an ageing cohort infected with chronic hepatitis C, and are expected to continue to rise as a consequence of the obesity epidemic. Clinical care and survival for patients with HCC has advanced considerably during the last two decades, thanks to improvements in patient stratification, an enhanced understanding of the pathophysiology of the disease, and because of developments in diagnostic procedures and the introduction of novel therapies and strategies in prevention. Nevertheless, HCC remains the third most common cause of cancer-related deaths worldwide. These LAASL recommendations on treatment of hepatocellular carcinoma are intended to assist physicians and other healthcare providers, as well as patients and other interested individuals, in the clinical decision-making process by describing the optimal management of patients with liver cancer.

Predictors of in-hospital mortality after acute variceal bleeding in patients with hepatocellular carcinoma and concurrent main portal vein thrombosis

BACKGROUND AND AIM

Risk factors for acute variceal bleeding in patients with hepatocellular carcinoma (HCC) and concurrent main portal vein thrombosis (PVT) remain unclear. We aimed to determine risk factors of in-hospital mortality after acute variceal bleeding for HCC patients with concurrent main PVT.

METHODS

We conducted a retrospective analysis of 102 HCC patients (83% men and 17% women) with concurrent main PVT and acute variceal bleeding. All patients received emergent endoscopy to define the bleeding source. Multivariable Cox proportional hazard regression analysis consisting of clinical, laboratory, and endoscopic parameters was performed to identify predictive factors for intrahospital mortality.

RESULTS

Twenty-eight (27.5%) patients died within admission. The median survival of all patients was 56 days. Multivariable Cox proportional hazard regression analyses revealed Child-Pugh score (adjusted hazard ratio [aHR]: 1.29 for each point; 95% confidence interval [CI]: 1.11-1.50), active bleeding on index endoscopy (aHR: 7.50; 95% CI: 3.05-18.4), esophageal varices as the bleeder (compared with gastric varices, aHR: 14.3; 95% CI: 3.12-66.1), failure to control bleeding (aHR: 38.0; 95% CI: 7.44-194), and serum creatinine (aHR: 1.28 for each increase of 1 mg/dL; 95% CI: 1.09-1.50) independently predicted in-hospital mortality.

CONCLUSIONS

Hepatic reserve, active bleeding on index endoscopy, failure to control bleeding, esophageal varices as the bleeder when compared with gastric varices, and renal function were independent predictive factors for in-hospital mortality in HCC patients with acute variceal bleeding and concurrent main PVT.

MELD score can predict early mortality in patients with rebleeding after band ligation for variceal bleeding

AIM: To investigate the outcomes, as well as risk factors for 6-wk mortality, in patients with early rebleeding after endoscopic variceal band ligation (EVL) for esophageal variceal hemorrhage (EVH).

METHODS: Among 817 EVL procedures performed for EVH between January 2007 and December 2008, 128 patients with early rebleeding, defined as rebleeding within 6 wk after EVL, were enrolled for analysis.

RESULT: The rate of early rebleeding after EVL for acute EVH was 15.6% (128/817). The 5-d, 6-wk, 3-mo, and 6-mo mortality rates were 7.8%, 38.3%, 55.5%, and 58.6%, respectively, in these early rebleeding patients. The use of beta-blockers, occurrence of hypovolemic shock, and higher model for end-stage liver disease (MELD) score at the time of rebleeding were independent predictors for 6-wk mortality. A cut-off value of 21.5 for the MELD score was found with an area under ROC curve of 0.862 (P < 0.001). The sensitivity, specificity, positive predictive value, and negative predictive value were 77.6%, 81%, 71.7%, and 85.3%, respectively. As for the 6-mo survival rate, patients with a MELD score ≥ 21.5 had a significantly lower survival rate than patients with a MELD score < 21.5 (P < 0.001).

CONCLUSION: This study demonstrated that the MELD score is an easy and powerful predictor for 6-wk mortality and outcomes of patients with early rebleeding after EVL for EVH.

Acute variceal hemorrhage

Variceal bleeding is a frequent and life-threatening complication of portal hypertension. The first episode of variceal bleeding is associated not only with a high mortality, but also with a high recurrence rate in those who survive. Therefore, management should focus on different therapeutic strategies aiming to prevent the first episode of variceal bleeding (primary prophylaxis), to control hemorrhage during the acute bleeding episode (emergency treatment), and to prevent rebleeding (secondary prophylaxis). These strategies involve pharmacological, endoscopic, surgical, and interventional radiological modalities. This article reviews management of acute variceal bleeding.

MELD score and hepatocellular carcinoma identify patients at different risk of short-term mortality among cirrhotics bleeding from esophageal varices

BACKGROUND/AIMS

The role of model for end stage liver disease (MELD) and the presence of hepatocellular carcinoma (HCC) as risk factors of short-term mortality in patients bleeding from oesophageal varices were evaluated.

METHODS

From February 2002 to August 2003, 172 cirrhotic patients admitted for the first episode of bleeding from oesophageal varices received vasoactive and endoscopic therapy. Patients' survival was evaluated at 6 weeks and 3 months. The role of MELD and HCC as independent risk factors of mortality was evaluated.

RESULTS

In the 172 patients, the overall mortality was 21.5% at 6 weeks and 30.2% at 3 months. MELD score resulted a good predictor of mortality either at 6 weeks or 3 months. Fifty-four patients (31.3%) had HCC. The presence of advanced HCC was an independent risk factor of mortality at 3 months. Patients with MELD score>15 and advanced HCC had a significantly worse survival than patients with MELD<or=15 and without HCC or with early HCC either at 6 weeks or 3 months

CONCLUSIONS

MELD score and the presence of HCC allow to identify patients at different risk of short-term mortality among cirrhotic patients at first episode of bleeding from oesophageal varices.

Endoscopic injection sclerotherapy for esophageal varices in cirrhotic patients with hepatocellular carcinoma: risk factors for survival

GOALS

We previously showed that endoscopic injection sclerotherapy (EIS) prolonged survival in patients with esophageal varices complicated by hepatocellular carcinoma (HCC) and liver cirrhosis. Here, we evaluated risk factors that affect EIS outcomes. Among factors, the difference between prophylactic and emergency EIS was of interest, and we analyzed precisely.

STUDY

Subjects were 134 patients with esophageal varices complicated by HCC and liver cirrhosis: 38 underwent emergent therapy for bleeding varices and 96 underwent prophylactic sclerotherapy.

RESULTS

During 2-year observation, 22 of the 38 (57.9%) and 38 of the 96 (39.6%) died. Analysis by univariate Cox's proportional hazard model indicated that prognosis of patients receiving emergency EIS was inferior to those with prophylactic EIS. However, multivariate Cox's analysis showed that emergency EIS itself extended survivals of those with esophageal varices complicated by HCC and liver cirrhosis. Patients' hepatic function (Child-Pugh classes) and tumor sizes were also statistically significant factors for survival. Neither prophylactic nor emergency EIS prolonged survival of patients with Child C hepatic function or those with HCCs larger than 5 cm.

CONCLUSIONS

The prophylactic sclerotherapy for esophageal varices prolongs long-term survival of patients with liver cirrhosis and HCC, better than emergency therapy. However, EIS itself had no beneficial effect on patients with poor disease status.

Management of portal hypertension after variceal hemorrhage

Each variceal bleed is associated with 20% to 30% risk of dying. Management of portal hypertension after a bleed consists of (1) control of bleeding and (2) prevention of rebleeding. Effective control of bleeding can be achieved either pharmacologically by administering somatostatin or octreotide or endoscopically via sclerotherapy or variceal band ligation. In practice, both pharmacologic and endoscopic therapy are used concomitantly. Rebleeding can be prevented by endoscopic obliteration of varices. In this setting, variceal ligation is the preferred endoscopic modality. B-blockade is as effective as endoscopic therapy and, in combination, the two modalities may be additive.

Feasibility and potential benefit of maintenance endoscopic variceal ligation in patients with unresectable hepatocellular carcinoma and acute esophageal variceal hemorrhage: a controlled trial

BACKGROUND

Patients with unresectable hepatoma and acute esophageal variceal bleeding have extremely high rates of recurrent bleeding and mortality. This controlled study evaluates the feasibility and potential benefit of maintenance endoscopic variceal ligation in these patients.

METHODS

Patients with unresectable hepatoma and acute esophageal variceal bleeding underwent emergent endoscopic variceal ligation. After hemostasis, patients were randomized to undergo maintenance or esophageal variceal ligation (EVL) as necessary (demand ligation).

RESULTS

Fifty-four patients underwent maintenance EVL and 55 demanded EVL. One or more subsequent EVL session could be performed in only 30 patients (55.6%) in the maintenance group (actual maintenance ligation). Logistic regression analysis found that hepatic function determines the feasibility of maintenance ligation (Child-Pugh's A+B vs. C, OR 23.00: 95% CI [5.26, 100.66]). The survival and recurrent bleeding rates were similar in both groups. A subgroup analysis of patients with Child-Pugh's A and B hepatic reserve in both the maintenance EVL group (n = 24) and demand EVL group (n = 25) was performed to assess the potential benefit of maintenance ligation. Maintenance ligation reduced the rate of recurrent bleeding compared with demand ligation (p = 0.043). Cox regression showed that portal vein thrombosis and tumors in both hepatic lobes were also factors together with EVL that determined recurrence of bleeding. Survival was similar in both groups.

CONCLUSIONS

Maintenance ligation is feasible in patients with unresectable hepatoma and variceal hemorrhage if they have a good hepatic reserve. Maintenance ligation might lower the rate of recurrent bleeding in this subgroup of patients.

Esophageal varices. I. Clinical presentation, medical therapy, and endoscopic therapy

The last half century has witnessed great advances in the understanding of the pathogenesis and natural history of portal hypertension in cirrhotics. Several pharmacologic and endoscopic techniques have been developed for the treatment of portal hypertension. The use of these agents in a given patient must be based on an understanding of the stage in the natural history of the disease and the relative efficacy and safety of the available treatment options.

Endoscopic injection sclerotherapy for esophageal varices prolonged survival of patients with hepatocellular carcinoma complicating liver cirrhosis

BACKGROUND

A prospective controlled study was performed between 1982 and 1991 to evaluate the efficacy of endoscopic injection sclerotherapy (EIS) in patients with esophageal varices complicated by hepatocellular carcinoma and liver cirrhosis.

METHODS

The study included 83 patients with esophageal varices, hepatocellular carcinoma, and liver cirrhosis. Forty-three patients (group 1) underwent prophylactic EIS or emergent EIS for bleeding varices. EIS was performed weekly 4 to 6 times until the varices disappeared. The remaining 40 patients (group 2) underwent conservative therapy and did not undergo EIS. Survival rates were compared between the 2 groups.

RESULTS

During the 5-year observational period, all patients who did not undergo EIS died. Sixteen in group 2 (40.0%) died of gastrointestinal bleeding including ruptured esophageal varices. In contrast, patients treated with EIS survived significantly longer (p<0.001). Nine patients (20.9%) treated with EIS experienced gastrointestinal bleeding as a result of which 5 (11.6%) died. EIS prolonged survival in patients classified as Child's A or B but did not affect survival in patients with Child's C hepatic function. EIS was effective in prolonging survival in patients with hepatocellular carcinomas smaller than 5 cm. However, EIS had no effect in patients with hepatocellular carcinomas that were larger than 5 cm. EIS prolonged survival only for patients with nodular hepatocellular carcinoma and had no effect in patients with massive and diffuse hepatocellular carcinoma. Further, EIS prolonged survival only for patients who did not have portal vein thrombosis.

CONCLUSION

Based on this prospective study, we concluded that EIS was effective in prolonging the survival period of a select subset of patients with hepatocellular carcinoma.

Characteristics of hepatocellular carcinoma presenting with variceal bleeding

Patients with hepatocellular carcinoma may present with variceal bleeding as the initial symptoms. The aims of this study is to investigate the characteristics of such patients. A total of 1046 hepatocellular carcinoma cases were retrospectively retrieved from our computer records between 1980 and 1993. The medical records and image studies were reviewed. The status of each patient was assessed at the time of presentation. A total of 14 (about 1 %) patients with hepatocellular carcinoma presented with variceal bleeding. Five (36%) did not have past history of liver disease. The tumour size ranged from 2.5 to 11.3 cm. Compared with hepatocellular carcinoma patients not presenting with variceal bleeding, these patients had a higher percentage of portal vein thrombosis (57.1 vs 19.4%). In two patients, the hepatic tumours were missed in the initial abdominal sonography. The average survival time was 71 days. Seven patients died within 2 months mainly due to variceal bleeding (41.6%). Variceal bleeding might be a clue to the presence of hepatocellular carcinoma with portal vein thrombosis even in patients without a previous history of liver disease. The tumours in such patients might be the infiltrative type, and thus the portal vein should be carefully worked-up. Overall, these patients have an extremely poor prognosis. In the management of patients with variceal bleeding, the possibility of hepatocellular carcinoma with portal vein thrombosis should not be overlooked, especially in areas where this cancer is prevalent.

Therapeutic results of endoscopic variceal ligation for acute bleeding of oesophageal and gastric varices

Endoscopic variceal ligation (EVL) using 'O' rings is widely accepted as a treatment of oesophageal varices that is at least as effective as endoscopic injection sclerotherapy but which produces fewer complications. Endoscopic variceal ligation using detachable snares has attracted attention as a safe and easy method of endoscopic treatment for gastric varices. Nineteen patients with acute bleeding from oesophageal or gastric varices were treated in the present study. Of these, 14 patients were treated with EVL using 'O' rings and five patients were treated with EVL using detachable snares and the treatment results were evaluated. Haemostasis was achieved in all patients. No serious complications of the procedures were observed. However, recurrences and rebleeding were observed in some patients during the maximum follow-up period of 24 months. Endoscopic variceal ligation using 'O' rings and detachable snares is useful for achieving haemostasis in cases of acute bleeding from oesophageal or gastric varices. However, additional endoscopic sclerotherapy may be needed to eliminate the variceal feeding vessels to further improve the long-term prognosis of these patients.

Surgical treatment for hepatocellular carcinoma and concomitant esophagogastric varices

Preventing a rupture of esophagogastric varices (EGV) is very important in aggressively treating hepatocellular carcinoma (HCC) in cirrhotic patients. We therefore performed simultaneous partial hepatic resection and direct interruption procedure on nine patients with HCC and concomitant EGV. Patients were selected on the basis of their stages of HCC and hepatic functional reserve. Postoperative hospital courses of all patients were uneventful. Six patients had recurrence of HCC and received non-surgical anti-tumor treatments. Only one patient had upper gastrointestinal bleeding at 18 months after operation, and the other eight patients have had no episodes of upper gastrointestinal bleeding during the follow-up period. The 5-year survival rate of these patients was 48%. This operative procedure is quite effective and is one of the treatments of choice for patients with less advanced HCC and concomitant risk of EGV.
