Introducing Liver Surgery to the MID NORTH COAST NSW Dr George Petrou FRACS 69Lake Rd, Port Macquarie NSW Hepatobiliary Surgery, Laparoscopic Surgery, Obesity Surgery, Hernia surgery, Endosurgery
Indications for liver surgery Colorectal metastases Hepatocellular carcinoma Cholangiocarcinoma Neuroendocrine tumours Hepatic sarcomas Some benign lesions Select metastases- breast, gastric, pancreatic, melanoma
Colorectal Cancer 2 nd most common cancer in Australia 2 nd cancer killer 50% patients with colorectal cancer have or will develop liver metastases 15% patients have liver metastases at time of diagnoses of primary 120 colorectal cancer resections performed in Port Macquarie per year
Selecting patients for liver surgery Fit for major abdominal surgery. 30% normal functioning liver remnant. Size and number of tumours in the liver does not determine operability. Site of the tumour is more relevant. Patients eligible for surgery – 40-50%
Patient work up to determine operability Routine blood tests. Triple phase CT abdomen and CT chest. Liver directed MRI. CT PET used in selective cases (suspected extrahepatic disease or recurrent colorectal cancer). Multidisciplinary team discussion. Anaesthetic work up.
New Chemotherapy FOLFOX- median survival 24 months New agents are pushing this 2 year hurdle successfully FOLFIRI, FOLFOXFIRI +/- VEG inhibitors Now chemo alone med survival > 2 years 5 year hurdle is only a matter of time
Synchronous Resection with bowel Rule: safe if minor liver resection is planned (2 or less liver segments to be removed)
Survival: Synchronous vs Metachronous
Number of lesions Rule: Doesn’t matter provided a clear margin and adequate remnant liver volume can be achieved.
Survival: No. of lesions
Portal Vein Embolisation Increases operability and safety with extended resection.
Small L Lateral Inoperable as not enough remnant liver left to make surgery safe
Right portal vein is radiologically embolised as a day procedure
The remnant liver grows after 4-6 weeks
RESECTION The tumour is now operable as surgery is now safe
Is it safe?
Literature Morbidity Morbidity 20-30% Bleeding 1-3% Bile leaks 10-30% Infection 10-30% Liver failure < 5% Wound problems 20% PE DVT 1-3%
Morbidity and Mortality Australia 30 day mortality 1-5% (3%) AUSTRALIA Only 3 centres have reported data 90% St George Hospital 10% Adelaide and Melbourne ANZHPBA consensus- centre should be doing 10 major resections per year
Mid North Coast NSW Established GIT MDT (Cancer Care Centre) Easily accessible high definition CT and MRI PET- important for recurrent colon cancer Established interventional radiology with experience in percutaneous drain placement Theatre team with experience in major vascular and GIT surgery Anaesthetic and ICU experience in major vascular and GIT surgery Established GIT medical oncology

Laparoscopic US George Petrou FRACS The liver tumour is easily seen at operation with US
Summary Introducing Liver Surgery to a Regional Hospital Challenging but exciting time Enthusiastic and supportive colleagues Preliminary results encouraging Volume increasing Prometheus stole the secret of fire and gave it to man
