Q

When we look at dysphagia, this can be with liquid and/or solids. If a patient is having difficulty with both solids and liquids is this likely to be a neuromuscular problem or a mechanical obstruction?

A
  • neuromuscular problem
  • achalasia for example
17
Q

When we look at dysphagia, this can be with liquid and/or solids. If a patient is having difficulty with solids that may then progress to liquids, is this likely to be a neuromuscular problem or a mechanical obstruction?

  • mechanical obstruction
  • could be a tumour, stricture etc..

19
Q

What is the primary method for diagnosing oesophageal cancers?

1 - Oesophago-Gastro-Duodenoscopy
2 - CT
3 - MRI
4 - endoscopic ultrasound

A

1 - Oesophago-Gastro-Duodenoscopy

  • biopsies can also be taken for histology

Barium swallow test can identify masses, strictures etc..

20
Q

What is often the primary method for staging oesophageal cancers once they have been diagnosed?

1 - Oesophago-Gastro-Duodenoscopy
2 - CT
3 - CT-PET
4 - endoscopic ultrasound
5 - staging laparoscopy

A

2 - CT
- CT-PET can also be useful

  • all of these methods can be used, it just depends on what the staging
21
Q

Early diagnosis and treatment is paramount in patients with oesophageal cancer. What % of patients have the potential of curative therapy?

1 - 0.35 - 0.45%
2 - 3.5 - 4.5%
3 - 35 - 45%
4 - >70%

A

3 - 35 - 45%

22
Q

If a patient has early disease of oesophageal cancer that has not spread beyond the layers of the oesophagus. Which of the following is the most appropriate treatment?

1 - endoscopic or primary surgery
2 - multimodal therapy (chemotherapy and/or radiotherapy, surgery)
3 - chemotherapy and/or radiotherapy, immunotherapy
4 - immunotherapy

A

1 - endoscopic or primary surgery

23
Q

If a patient with locally advanced (local lymph notes and tissues) oesophageal cancer, which of the following is the most appropriate treatment?

1 - endoscopic or primary surgery
2 - multimodal therapy (chemotherapy and/or radiotherapy, surgery)
3 - chemotherapy and/or radiotherapy, immunotherapy
4 - immunotherapy

A

2 - multimodal therapy (chemotherapy and/or radiotherapy, surgery)

24
Q

If a patient has a pallative diagnosis for oesophageal cancer, which of the following is the most appropriate treatment?

4 - immunotherapy

A

3 - chemotherapy and/or radiotherapy, immunotherapy

  • could also be just immunotherapy alone
  • could also have stenting to help symptoms
25
Q

In a surgery for oesophageal cancer, it is normally performed in a 2 stage process: abdominal and thoracic phase. Re-organise the order of the surgery using the labels below:

A

1 - laparotomy to open the abdomen and mobilise the stomach
2 - open up thoracic cavity to dissect diseases oesophagus and tumour

Q

- stage 1 - 70%
- stage 2 - 48%
- stage 3 - 36%
- stage 4 - 14%

A

Q

58 year old man who smokes, drinks 25u/ week has had some weight loss and a gradual worsening dysphagia for the past 4/12 in solids. He has noticed a recent rapid deterioration in dysphagia in both solids and fluids and is now vomiting up water. What is the most likely diagnosis?

1 - achalasia
2 - oesophageal cancer
3 - GORD
4 - anorexia nervosa

A

2 - oesophageal cancer

31
Q

Endobronchial ultrasound (EBUS)
is performed and the image below is provided, showing what?

1 - volvulus
2 - intusseption
3 - oesophageal cancer
4 - pancreatic cancer

A

3 - oesophageal cancer

May see a similar image in gastric cancer

32
Q

A patient diagnosed with oesophageal cancer is having swallowing fluids and solids. What is the best method of ensuring the patient is able to eat and drink?

1 - orally following blending
2 - radiologically inserted gastrostomy (RIG)
3 - percutaneous endoscopic gastrostomy
4 - parenteral nutrition

A

2 - radiologically inserted gastrostomy (RIG)

Side effects include diarrhoea

Percutaneous endoscopic gastrostomy requires a camera to be passed down the oesophagus, so this would be inappropriate.

33
Q

If a patient develops neutropenic sepsis due to the cancer treatment, in addition to initiating the sepsis 6, what can be given in an attempt to increase the neutrophil count?

1 -dexamethasone
