FN: Peptic Ulcer Disease Flashcards
Classification
Acute or Chronic
Acute
Usually due to drugs (NSAIDS, steroids) or stress
Chronic
Drugs
H. Pylori
Raised Calcium
Zollinger Ellison
Two types
Duodenal Ulcers
Gastric Ulcers
Duodenal Ulcers path
4x commoner than GU
1st part of duodenum (Cap)
M>F
duodenal Ulcers RF
H. Pylori Drugs: NSAIDS, steroids Smoking EtOH Increased gastric emptying Blood group O
Duodenal Ulcers presentation
Epigastric Pain:
Before meals and at night
Relieved by eating or milk
Gastric Ulcers path
Lesser curve of gastric antrum
Beware ulcers elsewhere (often malignant)
Gastric Ulcers Risk factors
H. pylori Smoking Drugs Delayed gastric emptying Stress: 1. Cushings: intracranial disease 2. Curling:L burns, sepsis, trauma
Gastric Ulcers presentation
Epigastric pain
- Worse on eating
- relieved by antacids
Wt. loss
Complications
Haemorrhage
Perforation
Gastric Outflow Obstruction
Malignancy
Haemorrhage
Haematemeis or melaena
Fe deficiency anaemia
Perforation
Peritonitis
Gastric Outflow Obstruction
Vomiting, colic, distension
Malignancy
Raised risk with H. pylori
Investigations
Bloods: FBc, urea (raised in haemorrhage)
C(13) breath test
OGD (stop PPIs >2 wks before)
Gastrin levels if Zollinger-ellison suspected
OGD process
CLO/urease test for H.pylori
Always take biopsies of ulcers to check for Ca
Management
Consverative
MEdical
surgical
Conservative
Lose wt. Stop smoking and reduced EOH Avoid hot dirnks and spicy food Stop drugs: NSAIDS, steroids OTC antacids
Medical
- OTC antacids: Gaviscon, Mg trisilicate
- H. pylori eradication
- Full-dose acid suppression for 1-2 mo
- PPIs: lansoprazole 30mg OD
- H2RAs: ranitidine 200mg nocte - Low-dose acid suppressionPRN
Surgery for PUD Concepts
No acid -no ulcer
Secretion stimulated by gastrin and vagus N.
Vagotomy
Truncal: reduce acid secretion but prevents pyloric sphincter relaxtion therefore must by combined with pyloroplasty or gastroenterostomy
Selective: vagus nerve only denervated where it supplies lower oesophagus and stomach - nerves of laterjet (supply pylorus) left intact
Antrectomy with vagotomy
Distal half of stomach removed _ anastomosis:
- directly to duodenum: billroth 1
- To small bowel loop w/ duodenal stump oversenL billroth 2 or polyp
Subtotal gastrectomy with Roux-en-Y
Occasionally performed for Zollinger-Ellison
occasional physical
Stump eakage
Abdominal fullness
REflux or bilious vomiting (improves with time)
Stricture
Complications Metabolic
Dumping syndrome:
- abdo distension, flushong, n.v
- Early: osmotchypovolaemia
- Late: reactive hypoglycaemia
Blind loop syndrome - malabsorption, diarrhoea
-Overgrowth of bacteria in duodenal stump
-Anaemia: Fe + B12
Osteoporosis
Wt. loss: malasborption of reduced calories intake
