Causes of Abdo Pain

Case Study Mr C, 35 year old man, presents to his GP with mild abdominal pain and yellowing of the whites of his eyes (noticed by his girlfriend who is a nurse). What other symptoms would you want to ask about?

Signs and Symptoms of Liver pathology Abdominal pain (RUQ) Jaundice Nausea, vomiting Weight loss Abdo distension Haematemesis and malaena Breast swelling, tesicular atrophy Confusion Spider naevi Palmar erythema Dupuytrens contracture Hepatomegaly, Spenomegaly

Case study cont: Has recently has ‘flu’ – has felt generally unwell, tired and vaguely nauseated. He is unsure but thinks he may have had a mild fever. What risk factors would you ask about?

Risk factors for liver disease High Alcohol intake Blood-to-blood contact (IVDU, Tattoos, infected transfusions, needlestick injuries) Unprotected sex Drugs (prescribed, OTC, herbal) Travel Family history of liver disease (autoimmune hepatitis, Wilson’s disease) Mr C is in monogamous sexual relationship with girlfriend for 2 months– she is on OCP. No barrier contraception. Drinks approximately 30 units alcohol / week. Denies any other risk factors. What first line investigations would you like to do?

Liver Function Tests Viral hepatitis: Alcoholic hepatitis ALT greatly raised (10 -100 x upper limit of normal) ALT moderately raised (2 -10 x upper limit of normal) Drug induced hepatitis Mixed picture: raised hepatic (AST, ALT) and Cholestatic (Alk Phos and GGT) markers Abnormal clotting (prolonged PT or INR) may indicate acute liver failure

Drugs commonly associated with Hepatitis Acute hepatocellular damage: Paracetamol (dose related) Alcohol (dose related) TB drugs Anticonvulsants Azathioprine Methotrexate Chronic active hepatitis Nitrofurantoin Isoniazide Intrahepatic cholestasis Azathioprine Oestrogens erythromycin

Hep A Hep B Hep C Hep D Hep E Route of transmissio n Faecal-oral Blood products, (contaminate body fluids, d water/food, sexual contacts oro-anal sex) Blood products As for Hep B Contaminated water People at risk Childcare workers, MSM vertical transmission, sexual partners, healthcare workers, Tattoos, body piercings, blood transfusions, IVDU, tattoos Those at risk of Hep B or with chronic Hep B Travel to endemic areas, and sporadic outbreaks associated with poor sanitation eg refugee camps Less commonly: vertical transmission, sexual transmission Potential for chronic infection none Common in infants (90%), rarer in adults (10%) 80% develop chronic infection Co-infection with Hep B none Incubation period 3 weeks (range 2 -7) 10 weeks 7 weeks 5 weeks (range 4 -26) (range 2 -21) (range 3 -7) (range 3 -8) Other causes: EBV, CMV, paravirus B 19, dengue, yellow fever.

Hepatitis E endemic areas

Mr C and his girlfriend are both tested for viral hepatitis Girlfriend Mr C

Hepatitis B Serological Markers

65 year old man who hasn’t been to his GP in years comes into A+E with an uncomfortable swollen abdomen What are the differential diagnoses?

5 Fs of distended abdomen Fat Faeces Fluid Foetus Flatus How would you examine for fluid (ascites)?

Shifting Dullness Does the presence of ascites prove that this patient has liver disease?

What are the possible causes of ascites?

Cirrhosis: common end point of many disease processes Alcohol excess Hepatitis B Hepatitis C Non-alcoholic Fatty Liver disease / Non-alcoholic Steatohepatitis Haemachromatosis Primary Biliary Cirrhosis Primary Scelosis Cholangitis Autoimmune hepatitis Wilson’s disease and other inherited metabolic disorders

How would you investigate decompensated liver disease? Bloods: likely increased biliruben, AST, ALT, alk phos, GGT; Decreased albumin, increased PT/INR (reduced synthetic Decreased WCC and platelets (hypersplenism); Look for the cause: serology, autoantibodies, iron studies Imaging: liver US and doppler, MRI Ascitic tap: Biopsy: confirm clinical diagnosis function);

US liver “fibrotic, structurally abnormal nodules in liver …. Compatible with cirrhosis. Doppler shows signs of portal hypertension. ”

Complications of Cirrhosis Anaemia (folate deficiency, hypersplenism) Thrombocytopenia (hypersplenism) Coagulopathy (reduced production of clotting factors) – can lead to DIC Oesophageal varices Spontaneous Bacterial Peritonitis Hepatic encephalopathy Hepatocellular carcinoma

How would you manage this patient? Patient education and support Treat underlying cause Adequate nutrition (calorie and protein intake) Careful prescribing Therapeutic ascetic tap Alcohol abstinence (also important in nonalcohol induced cirrhosis) Monitoring for further complications: Alcohol dependent individuals will require: Chlordiazepoxide, Thiamine, Vitamin B oesophageal varicies or HCC ? transplant

Case Study “A 17 year old girl presents to the GP with a 8 week history of fatigue. She also reports frequent episodes of pyrexia and intermittent episodes of diarrhoea over this period. Over the last 48 hours she has had 14 episodes of watery diarrhoea” What other questions would you ask her? ? ?

She denies. . . She reports. . . . Fatigue – low energy levels SOBOE Palpitations Frequent Pyrexia Abdominal pain – generalised cramps Diarrhoea – no blood or mucus Weight Loss jaundice, dyspepsia, vomiting, malena, constipation, ulcers Changes in appetite Changes in mensustral cycle urinary symptoms No recent travel No changes / alterations to her diet

What are you going to do next? ? Clinical Examination Investigations Urine Dip and MSU Bloods : FBC, U&E's , CRP, ESR, LFT's, TFT's, Electrolytes, Anti -TTG, Blood Cultures? ? Stool culture Imaging

CASE STUDY A 25 year old girl presents with a 8 week history of generalised abdominal cramps and diarrhoea. They are loose stool, no blood or mucus and can occur 8 -10 times a day. She also reports that she is frequently tired and stressed. What else do you want to know? ? ?

Irritable bowel Syndrome Incidence: common (female 20 -40) ; 40 % people attending secondary care 6 months of symptoms before diagnosis Can be predominantly constipation or predominantly diahorrea. Abdominal pain/ Bloating Anxiety / depression Incomplete emptying/ incontinence/ urgency Constitunal symptoms : tiredness, lethargy, arthalgia, urinary symptoms, dyspurunina. RED FLAG SYMPTOMS: Bleeding, Nocturnal symptoms, weight loss, Age > 50

Treatment Options Reassurance and support Address / Treat underlying medical issues Lifestyle advice : Dietary modification – excluding food groups. Smoking and alcohol Symptomatic relief : Bloating – Peppermint oil Constipation – increase fibre and fluid intake Antispasmodics – mebevrine

Case Study “A 65 year old man presents with a 4 day history of black tarry stools. He reports that they are becoming more frequent and loose. He also reports nausea and one episode of vomiting this morning. He also reports that he has a back ache for the past fortnight and has been taking OTC painkillers for it and would like you to prescribe some more”

Causes of Upper GI bleeding Common causes: Mallory -Weiss tears Angiodysplasia Bleeding Disorders Gastritis / gastric erosion Peutz- Jeugher's Syndrome Duodenitis Oesphagitis Ulcers – Peptic ulcers (40%) Rarer causes: Varices – Secondary to portal hypertension (17%) Osler – Webb – Rendu Syndrome

Examination / Investigation On Examination: He is tachycardic, at 111 bpm / regular and borderline hypotensive 105/72. He is tender in the epigastrium and peri-umbilically. There is some voluntary guarding. Bowel sounds are normal. DRE – Malodorous black tarry stool. No fresh blood. Investigations: Bloods : Hb -10. 0 , Urea -21 , Creatnine 66, WCC- 7. 0, platelets 260, CRP – 2. 2, LFT's – NAD. AXR – NAD Erect CXR – No free air under the diapgram

Management Bleep : RR -30 BP- 90 /66 , HR -122, CRT > 3, Sats – 94% A - No airway compromise B – O 2, ABG C – IV access + Fluid Challenge (which? ? ), Bloods. IV PPI, erect CXR, AXR D – GCS, Pupils , Glucose E - everything else: check notes, CALL FOR HELP RE- ASSESS

Rockall Score Pre-scope score : predicts the morbidity and mortality Post -scope score : predicts the risk of re-bleeding

Bleeding secondary to ulcers ABC approach IV PPI Endoscopy: CAUTERISTION or CLIPPING of the ulcer Bleeding secondary to varicies This is a sign of decompensation ABC approach IV Terlipressin (+ - Propanalol) Clotting abnormality – correct it Octreotide ( often given by seniors) Secondary prevention (propanolol)

Management of Variceal Bleeding Sengstaken Blakemore Tube : Balloon Decompression TIPS : Trans-jugular intrahepatic porto systemic shunt

A catheter into the hepatic vein, guidewire was passed into a portal vein branch. The tract was dilated with a balloon, and contrast injected. A metallic stent placed over the wire TIPS
