Background Information

Hepatocellular carcinoma is the 5th most common cancer in the world

Prevalent among Asian countries (hepatitis B and C endemic areas)

Common presentations: – hepatomegaly– detected during surveillance

3-15% of all HCC patients presented with rupture Locally most common cause of spontaneous

haemoperitoneum !

Llovet JM et al.. Lancet. 2003 Dec 6;362(9399):1907-17.


Ruptured HCC Common symptoms:

– shock 67%– abdominal pain 66%– abdominal distension 16%

Main cause of death: – hypovolaemia– liver failure

Management– Evolving trend– Advances in treatment modalities, improving technique

Miyamoto M et al. Am J Gastroenterol 1991; 16: 334-6


Prognostic factors

Bilirubin Portal vein invasion Shock upon presentation AFP level Child’s status

Tan FL et al. ANZ J Surg. 2006 Jun;76(6):448-52.


Treatments available

Conservative Open haemostatic surgery Emergency liver resection TAE (transcatheter arterial embolization)

New treatment– Radiofrequency ablation


Conservative Management

Supportive– Correct hypovolaemia

– Correction of coagulopathy

– close monitoring

conservative management indicated in:– Stable patient with radiological evidence of rupture

– Poor premorbid

– Advanced tumour stage

high mortality 90-100%

Leung KL et al. Arch Surg. 1999 Oct;134(10):1103-7.


Open haemostatic surgery

Options– Perihepatic packing

– Suture plication

– Hepatic artery ligation

– Alcohol injection

No larges scale studies comparing different modalities of treatment

High mortality up to 70% 3 months

Yoshida H et al. J Hepatobiliary Pancreat Surg. 2008;15(2):178-82. Epub 2008 Apr 6.


Emergency Hepatectomy

Benefits Both curative and bleeding control high mortality (operative mortality 28.5-54.5%) But elective hepatectomy: 0-10%

Tan FL et al. ANZ J Surg. 2006 Jun;76(6):448-52. Yoshida H et al. J Hepatobiliary Pancreat Surg. 2008;15(2):178-82. Epub 2008 Apr 6. Lai EC et al. Ann Surg. 1989 Jul;210(1):24-8.


Emergency Hepatectomy (2)

Pros– Single procedure with curative intent– No delay

Cons– Unstable patient– Coagulopathies– Unknown liver function reserve– Unknown tumour load– Compromised margins

Only considered in selective cases


The current treatment philosophy is…

Effective means of bleeding control Selective Less collateral damage

– preserving as much liver function as possible

Not aiming at cure in the emergency setting Minimal invasive Would not hinder subsequent definitive

treatment


How to achieve these goal?

Effective means of bleeding control Selective Less collateral damage

– preserving as much liver function as possible

Not aiming at cure in the emergency setting Minimal invasive Would not hinder subsequent definitive treatment


Transcatheter Arterial Embolization

First reported in early 80s Treatment of choice since early 90s Effective in bleeding control in >70% cases In-hospital mortality 0-30% Compared with hepatic artery ligation

– similar haemostasis success rate

– mortality ~ 70%

Availability of expert interventional radiologists !

Contraindications

Decrease portal blood flow– Main portal vein occlusion

– Marked cirrhosis with diminished portal blood flow

Severe hepatic dysfunction– Bilirubin cutoff: 50 micromol/l

– encephalopathy

Ngan H et al. Clin Radiol. 1998 May;53(5):338-41.


New Option: RFA

Introduced in late 90s Proven to be effective in tumour

ablation– size <= 5cm

– up to 3 nodules with size <=3cm

Less morbidity especially with percutaneous approach

RFA in bleeding control

Working mechanism: heat then necrosis

Proven to be effective in bleeding control– Less blood loss in RF assisted hepatectomy

compared with hepatectomy alone

– Efficient and safe method for grade III to IV hepatic traumas using dog models

Felokouras E et al. Am Surg. 2004 Nov;70(11):989-93. Mitsuo M et al. World J Surg. 2007 Nov;31(11):2208-12; discussion 2213-4.


Role of radiofrequency ablation in ruptured HCC

No large scale study for bleeding human cases yet Only less than 5 case reports so far

1 month post op


The next stage

Restage patient Baseline liver function after recovery Tumour load Patient’s premorbid

Elective definitive treatment– Hepatectomy

– Local ablative therapy


The next stage after bleeding controlled……

Ruptured = T4 disease, even if small size Recent study comparing ruptured group with

different stages of non ruptured patients, both receiving elective hepatectomy

Cumulative survival rate similar to that of stage 2/ 3 disease

Bring home message

TAE is the choice of haemostasis In case TAE contraindicated/ failure

– RFA as a potential new treatment modality
