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

Treatments available
Conservative
Open haemostatic surgery
Emergency liver resection
TAE (transcatheter arterial embolization)
New treatment
– Radiofrequency ablation
© 2008 IBM Corporation11
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

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

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%

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

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

Role of radiofrequency ablation in ruptured HCC
No large scale study for bleeding human cases yet
Only less than 5 case reports so far

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
