Gastric Disease Flashcards
What are the symptoms of dyspepsia?
Upper abdominal discomfort Retrosternal pain Anorexia Nausea Vomiting Bloating Early satiety Heartburn
What are the ALARMS symptoms to look for when considering referring for endoscopy?
Anorexia
Loss of weight
Anaemia – iron deficiency
Recent onset >55 years or persistent despite treatment
Melaena/haematemesis (GI bleeding) or mass
Swallowing problems - dysphagia
What blood tests should be done in a patient with dyspepsia?
FBC Ferritin LFTs U&Es Calcium Glucose Coeliac serology/serum IgA
Describe H.Pylori
Gram negative
Spiral-shaped
Microaerophilic
Flagellated
How is H.Pylori diagnosed?
Serology: IgG against H. pylori
13C /14C Urea Breath Test
Stool antigen test – ELISA - need to be off PPI for 2 weeks
Invasive-Histology: gastric biopsies stained for the bacteria
Culture of gastric biopsies
Rapid slide urease test (CLO)
What are three types of gastritis?
Autoimmune-development of antibodies against the gastric parietal cells
Bacterial- H.Pylori infection
Chemical- bile, NSAIDS, alcohol
Also are more predisposed to gastritis from several endocrine disorders
What are the symptoms of peptic ulcers?
Epigastric pain is the main feature (pointing sign, may be relieved by antacids)
Nocturnal/hunger pain (more common in DU)
Back pain (may suggest penetration of a posterior DU)
Nausea and occasionally vomiting
Weight loss and anorexia
Only sign may be epigastric tenderness
If the ulcer bleeds, patients may present with haematemesis and/or melaena, or anaemia
What is the eradication therapy for H. Pylori infection?
Triple therapy
Clarithromycin
Amoxycillin or metronidazole (tetracycline if penicillin allergic)
PPI such as omeprazole
What are the signs and symptoms of gastric outlet obstruction?
Vomiting – lacks bile, fermented foodstuffs
Early satiety, abdominal distension, weight loss, gastric splash
Dehydration and loss of H+ and Cl- in vomit
Metabolic alkalosis
Bloods – low Cl, low Na, low K, renal impairment
How do patients present with gastric cancer?
Dyspepsia, early satiety, nausea & vomiting, weight loss, GI bleeding, iron deficiency anaemia, gastric outlet obstruction
