Q

How do you manage a patient with cirrhosis?

A

GENERAL = nutrition, stop alcohol, avoid NSAIDs, sedatives and opiates. Colestyramine helps with pruritus.
SPECIFIC:
hep induced cirrhosis = ursodeoxycholic acid
Ascites = bed rest, fluid restrict, low salt diet, spironolactone
SBP = cefotaxime or tazocin or metronidazole
Vit K for any coagulopathy

A

(i) oesophagoscopy with biopsy is 1st-line

Q

What are the (i) investigations (ii) management for patients with achalasia?

A

(i) CXR - fluid level in dilated oesophagus
Barium swallow - Dilated tapering oesophagus
(ii) endoscopic balloon dilatation then PPIs
Botulinum toxin injection if non invasive
Ca channel blocker and nitrates may also relax sphincter

Q

What are the (i) investigations (ii) management for patients with oesophageal varices?

A

(i) FBC, U+E, LFTs, coagulation profile
Hep B+C serology if history suggests viral hepatitis
OGC (gastroscopy) is best imaging
(ii) initially = resuscitation, assess airway + obtain venous access. Blood transfusion, volume resus + possible transfusion of FFP+platelets
- during resuscitation, a vasoactive drug should be started - telipressin or somatostatin IV
Endoscopic band ligation performed ASAP
- prophylactic Abx = norfloxacin (oral) or ceftriaxone (IV)

17
Q

What are the (i) investigations (ii) management for patients with mallory-weiss tear?

A

(i) Hb, Hct, Platelets, urea, creatinine + electrolytes
Blood type + antibodies
CXR - to rule out other chest pathology
Risk assess - Glasgow-blatchford indicates need for endoscopy or outpatient management, Rockall score assesses risk of adverse outcome after acute bleed
(ii) initial resuscitation - haemoclip placement (OGD) and adrenaline (around bleeding site). 2nd line = endoscopic band ligation + adrenaline
- give PPI (pantoprazole) BEFORE endoscopy

18
Q

What are the (i) investigations (ii) management for patients with colorectal cancer?

A

(i) endoscopy (colonoscopy)
CEA tumour marker
CT colonography
(double barium enema as alternative to colonoscopy)
Routine FBC, LFT, bone profile + renal function
(ii) surgical resection
chemo +- radiotherapy pre or post-op depending on stage

19
Q

What are the (i) investigations (ii) management for patients with ulcerative colitis?

A

pANCA +ve
(i) FBC, ESR+CRP, U+E, LFT, blood culture
faecal calprotectin
stool culture + sensitivity, c.diff testing
Abdo xray, erect CXR for perforation
Colonoscopy + biopsy (crypt abscesses)
(ii) 1 = topical mesalazine
2 = topical steroids (rectally) OR oral mesalazine
3 = oral steroids +- tacrolimus
REFRACTORY DISEASE:
1 = thiopurines (azathioprine, mercaptopurine)
2 = TNF alpha inhib (inflixumab, adalimumab)
3 = vedolizumab
4 = ciclosporin or methotrexate
5 = colectomy

20
Q

What are the (i) investigations (ii) management for patients with Crohn’s disease?

A

ASCA +ve and -ve pANCA
(i) FBC, ESR+CRP, U+E, LFT, INR, ferritin, TIBC, B12, folate
faceal calprotectin
Stool culture + sensitivity + c.diff testing
Colonoscopy + rectal biopsy
Plain abdo xray/CT
(ii) mild attack = budesonide + azathioprine
moderate = oral steroids
severe = admit for IV steroids, nil by mouth + IVI plus metronidazole IV. After 5d switch to oral steroids. If not improving, infliximab and adalimumab have a role
Also used = azathioprine, sulfasalazine, TNF alpha inhib, methotrexate, Abx

21
Q

What are the (i) investigations (ii) management for patients with Diverticular disease?

A

(i) colonoscopy or barium enema (there is a risk of perforation in the acute setting with these) so use abdominal xray
in diverticulitis there will be increased WCC and CRP
(ii) high fibre diet and bulk producing laxatives
If diverticulitis = analgesia, oral Abx (amoxicillin or ciprofloxacin AND metronidazole), Iv fluids, NBM, CT guided drainage if abscess present

22
Q

What are the (i) investigations (ii) management for patients with hepatocellular carcinoma?

A

(i) FBC, clotting, LFT, hepatitis, serology, AFP
Imaging = US+CT to guide biopsy, MRI to distinguish benign from malignant
ERCP + biopsy if cholangiocarcinoma
Liver biopsy for histological diagnosis
(ii) Surgery - resection
Liver transplant
Transarterial chemo-embolisation (TACE) or radiofrequency ablation (RFA) bridging therapy

23
Q

What are the (i) investigations (ii) management for patients with pancreatic carcinoma?

A 
(i) CA 19-9 marker
US + CT + biopsy
Endoscopic sonography (EUS) is best for diagnosis and staging
(ii) surgery - pancreatoduodenectomy
laparoscopic excision 
post-op chemotherapy
palliation of jaundice = stent insertion
24
Q

What is the treatment for a jaundice patient with symptomatic gallstone(s)?

A

Cholecystectomy - often performed laparoscopically
ERCP with stenting or stone extraction or both
- may require lithotripsy modalities, papillary balloon dilatation and long-term biliary stenting

if simple dissolving required use ursodeoxycholic acid

25
Q

What are the (i) investigations (ii) management for patients with primary biliary cholangitis?

A

(i) BLOOD: increased ALP GGT and mild rise in AST+ALT
USS to exclude extrahepatic cholestasis
(ii) bile acid analogue = ursodeoxycholic acid
- prednisolone + azathioprine if patient has a more inflammatory variant of the disease (significantly raised IgG)
Give colestyramine as antipruritic treatment

26
Q

What are the (i) investigations (ii) management for patients with primary sclerosing cholangitis?

A

(i) raised ALP, then raised bilirubin
AMA -ve but ANA, SMA + ANCA may be +ve
ERCP distinguishes large from from small duct disease
liver biopsy
(ii) liver transplant for end stage disease
ursodeoxycholic acid may protect against colon cancer
colestyramine for pruritis

27
Q

What drug is used to treat paracetamol overdose?

A

acetylecysteine
