Q

gastric vs duodenal ulcer

A
DU
- Before meals and at night
- Relieved by eating
§ GU
- Worse on eating (→ ↓ wt.)
- Relieved by anatacids

duodenal are commoner

bleeding
perforation
gastric outflow obstruction
malignancy

26
Q

investigating peptic ulcers

ulcer biopsy
gastrin levels if suspect Zoll El syndrome suspected

27
Q

peptic ulcer disease treatment

A

avoid risk factors
lanzoprazole

surgery:
vagotomy - cut vagal nerve supply to reduce acid secretion, widening of outlet needed too
antrectomy and anastom

28
Q

complications of peptic ulcer surgery (antrectomy, vagotomy)

Dumping syndrome
§ Abdo distension, flushing, n/v, fainting,
sweating
§ Early: osmotic hypovolaemia
§ Late: reactive hypoglycaemia
• Blind loop syndrome → malabsorption, diarrhoea
§ Overgrowth of bacteria in duodenal stump
• Vitamin deficiency
§ ↓ parietal cells → B12 deficiency
§ Bypassing proximal SB → Fe + folate
deficiency
§ Osteoporosis
• Wt. loss: malabsorption of ↓ calories intake

30
Q

upper GI bleeding management pathway

A

RESUS
• Head down
• 100% O2, protect airway
• 2 x 14G cannulae + IV crystalloid infusion up to 1L.
• Bloods: FBC, U+E (↑ urea), LFTs, clotting, x-match 6u,
ABG, glucose

BLOOD if shocked (O neg and send G+S)

maintenance and correct blood abnormalities (thiamine if alcohol)

terlipressin and abx if variceal

URGENT OGD

31
Q

OGD variceal treatment

A

2 of: banding, sclerotherapy, adrenaline, coagulation
• Balloon tamponade ¯c Sengstaken-Blakemore tube
§ Only used if exsanguinating haemorrhage or failure
of endoscopic therapy
• TIPSS if bleeding can’t be stopped endoscopically

32
Q

OGD if vessel or ulcer bleeding

  • Adrenaline injection
  • Thermal / laser coagulation
  • Fibrin glue
  • Endoclips
33

38
Q

what is the TIPSS procedure?

A

IR creates artificial channel between hepatic vein and
portal vein → ↓ portal pressure.
• Colapinto needle creates tract through liver
parenchyma which is expand using a balloon and
maintained by placement of a stent.
• Used prophylactically or acutely if endoscopic therapy
fails to control variceal bleeding.

39
Q

perforated peptic ulcer presentation

A

• Sudden onset severe pain, beginning in the
epigastrium and then becoming generalised.

• MI

40
Q

peptic ulcer perf investigations

A

bloods G+S, clotting, coag
urine dip
erect CXR (stand for 15 mins) - air under diaphragm

41
Q

managing peptic ulcer perf

A
NBM 
fluid resus 
abx 
analgesia
antiemetic

can consider conservative if no peritonism (1/2 will self-seal)

surgery- duodenal = washout and omental repair, gastric - excise and repair

screen ulcer for cancers
treat afterwards for H pylori
