Mouth or throat

Oesophagus

  5. Age
  6. COPD
26

A

Cancer; mouth, throat, oesophageal

28

A

Dysphagia to liquids or coughing after swallowing liquids

29
Q

What is ‘melaena’?

A

Production of dark sticky faeces containing partly digested blood, as a result of internal bleeding or the swallowing of blood

Its black and tarry as has gone through the GI tract so blood has been altered by enzymes

30
Q

Is melaena present if someone is having a high volume GI bleed from upper GI tract e.g. stomach or oesophagus?

A

Normally present as haematemesis (vomiting of blood) instead

A degree of melaena may also be present

31
Q

Where may fresh blood from the anus be coming from?

A

More likely to be coming from colon

Bowel cancer? Diverticulum disease?

32
Q

Causes of an upper GI bleed?

A
  • Peptic ulcer
  • Gastritis
  • Varices
33
Q

What are varices?

A

Oesophageal varices are enlarged veins in the esophagus. They’re often due to obstructed blood flow through the portal vein, which carries blood from the intestine, pancreas and spleen to the liver

34
Q

What is a Mallory Weiss tear?

A

A tear of the tissue of your lower oesophagus. It is most often caused by violent coughing or vomiting.

35
Q

What is a Mallory Weiss tear usually preceded by?

A

A vomiting episode and produces fresh blood in the vomit

36
Q

Why can liver cirrhosis lead to GI bleed?

A

People who have cirrhosis may develop varices in the oesophagus. As the blood pressure in the portal vein system continues to increase, the walls of these expanded veins become thinner, causing the veins to rupture and bleed. This is called variceal bleeding.

37
Q

What is Murphy’s sign?

A

A manoeuvre during a physical examination as part of the abdominal examination. It is useful for differentiating pain in the right upper quadrant.

A

Addisonian crisis

41
Q

What is Addisonian crisis?

A

With adrenal insufficiency, the inability to increase cortisol production with stress can lead to an addisonian crisis.

49
Q

When is a plain abdominal x-ray helpful?
