Mangement of major abdominal trauma

Clinical features of serious liver injury Hypovolaemic shock Hypotension Tachycardia Decreased urine outpu Low central venous pressure Abdominal distension

Criteria for non-operative management of liver injuries Haemodynamically stable following

resuscitation No persistent or increasing

abdominal pain or tenderness No other peritoneal injuries that

require laparotomy <4 units of blood transfusion

required

Indications for laparotomy Stab or gunshot wounds that have

penetrated the abdomen Signs of peritonitis Unexplained shock Evisceration Uncontrolled haemorrhage Clinical deterioration during

observation

Liver Trauma – Surgical management Stop haemorrhage (Pringle) Remove dead or devitalised liver

tissue Ligate or repair damaged blood

vessels and bile ducts



Stellate fracture of right lobe of the liver



Packing of bleeding liver

Postoperative Complications Rebleeding from injury Bile leaks Ischaemic segments of the liver Infected fluid collections



Large intrahepatic haematoma in patient with blunt trauma

Liver Trauma - Prognosis Overall mortality 10-15 % Mortality after blunt trauma > 20

% If three major organs are injured

mortality approaches 70 %

Pyogenic liver abscess – typical features Right upper quadrant pain and

tenderness Nocturnal fevers and sweats Anorexia and weight Raised right hemidiaphram in

chest radiograph Raised white cell count with mild

anaemia

Origins and causes of pyogenic liver abscess Biliary tract – Gall stones,

cholangiocarcinoma, strictures Portal vein – Appendicitis, diverticulitis,

Crohn‘s disease Direct extension of: Gallbladder empyema Trauma Iatrogenic – Liver biopsy, blocked biliary

stent

Microbiology E. coli, Klebsiella pneumoniae,

bacteroides, enterococci Fungal or opportunistic organisms

due to immunosuppression as a result of AIDS, intensive chemotherapy and transplantation

Treatment Antibiotics – Penicillin,

aminoglycoside (or cephalosporin), metronidazole

Treatment for two to four weeks depending on the clinical response

Drainage requirements for liver abscesses None – multiple small abscesses

that respond to antibiotics Percutaneous aspiration –

abscesses <6cm Percutaneous catheter drainage –

abscesses >6cm

Drainage requirements for liver abscesses – Open surgery Failed percutaneous drainage Very large or multilocular

abscesses Associated intra-abdominal

infection requiring surgery such as bile duct stones

Amoebic liver abscess - Epidemiology About 10 % of the world‘s

population is chronically infected with Entamoeba histolytica

Amoebiasis is the third commonest parasitic cause of death, surpassed only by malaria and schistosomiasis

Symptoms of amoebic liver abscess Pain Enlarged liver with maximal tenderness

over abscess Intermittent fever with night sweats Weight loss Nausea Vomiting Cough Dyspnoea

Amoebic liver abscess - Diagnosis Serological tests Stool may contain protozoal cysts Abscess usually solitary – right

lobe in 80% of cases Abscess contains sterile pus and

reddish-brown liquefied necrotic liver tissue

Amoebic abscess - Treatment 95 % resolve with metronidazole

alone (800 mg three times a day for five days)

After the abscess – diloxanide furate 500 mg, eight hourly for seven days to eliminate intestinal amoebae

Amoebic abscess - Surgery Surgical drainage is required only

if the abscess has ruptured causing amoebic peritonitis

Hydatid disease - Presentation Liver enlargement Right upper quadrant pain Rupture of the cyst into the

peritoneal cavity –urticaria, anaphylactic shock, eosinophilia

Erosion into bile duct – jaundice, cholangitis



Lifecycle of Echinococcus granulosus

Hydatid disease – Diagnosis Ultrasonography, computed

tomography Serological tests ERCP



Computed tomogram showing hydatid cyst: daughter cysts containing hydatid larvae are visible within the main cyst



Operative specimen of opened hydatid cyst showing multiple daughter cysts

Hydatid disease – Treatment I Surgery – 1. Aspiration of cysts and

replacement by a scolicidal agent such as 0.5% sodium hypochlorite

Surgery - 2. The cysts are carefully shelled out by peeling the endocyst off the host ectocyst layer along ist cleavage plane

Hydatid disease –Treatment II Bile leakages are sutured The cavity is drained and filled

with omentum Liver resection seldom necessary Albendazole is given for two weeks

postoperatively

Liver tumours Cysts Benign tumours – Haemagiomas,

liver cell adenoma, focal nodular hyperplasia

Malignant tumours – Hepatocellular carcinoma, metastatic tumours

Characteristics of simple cysts Thin walled Contain clear fluid Contain no septa or debris Surrounded by normal liver tissue Usually asymptomatic Present in 1 % of population

Liver cysts Treatment only when symptomatic –

usually laparoscopic cyst fenestration NOTE - Thick walled cysts and those

containing septa, nodules or echogenic fluid may be cystic tumours

Cystic dilatations of the bile ducts (Caroli‘s disease) are premalignant (cholangiocarcinoma)



Polycystic liver disease

Haemangiomas Incidence 3 % Malignant transformation and

spontaneous rupture are rare Diagnosis by contrast enhanced

computed tomography Resection is indicated only for

large symptomatic tumours

Liver cell adenoma Predominantly in women of

childbearing age Risk of rupture 10 % Risk of malignant transformation

10 % Liver resection necessary

Focal nodular hyperplasia Usually asymptomatic Not premalignant It does not require treatment

unless symptomatic Sometimes diagnosis difficult to

establish – histology should be determined by surgical resection

Hepatocellular carcinoma Commonest malignant tumour

worldwide One million new cases a year

worldwide 80 % occur with cirrhotic livers Established viral infection – 10 years

to develop chronic hepatitis – 20 years to develop cirrhosis – 30 years to develop carcinoma



Distribution of hepatocellular carcinoma

Hepatocellular carcinoma Ultrasonography Alpha fetoprotein >500 ng/ml Surgical resection feasible in less

than 20 % of patients Average operative mortality is 12

% in cirrhotic patients 5-year survival 15 %

Hepatocellular carcinoma <5 cm tumours – LTX Contraindication to LTX – alcohol

injection, radiofrequency ablation Larger tumours – transarterial

embolisation with lipiodol and cytotoxic drugs (cisplatin or doxorubicin)



Large hepatocellular carcinoma

Colorectal liver metastasis 8-10 % of patients undergoing

curative resection of colorectal tumours have isolated liver metastasis suitable for liver resection

5-year survival after resection 30 %



Solitary liver metastasis in segment IV



Inoperable extensive liver metastasis

Liver resection A fit patient with a healthy liver will

regenerate a 75 % resection within three months

Segmental anatomy with each of the eight segments supplied by ist own branch of the hepatic artery, portal vein and bile ducts (Couinaud 1957)

Mortality 5 %



Couinaud’s segmental anatomy of the liver



Intraoperative view after left hepatectomy – raw surfaces of liver are coated with fibrin glue after resection to aid hemostasis and

prevent small bile leaks

Liver transplantation - Indications Primary biliary cirrhosis Primary sclerosing cholangitis Cryptogenic cirrhosis Chronic active hepatitis (Hep B and

C) Alcoholic liver disease (after a

period of abstinence)

Timing of LTX – Signs of decompensations Tiredness, Ascites, Encephalopathy Peripheral oedema Jaundice Spontaneous bacterial peritonitis Bleeding oesophageal varices Low albumin concentration Raised prothrombin time

Acute liver failure – Paracetamol overdose Renal failure develops as a

hepatorenal syndrome Early deaths result from raised

intracranial pressure Death in later stages – multiorgan

failure and systemic sepsis Mortality from fulminant liver

failure can be as high as 90 %
