Q

What is Hypomotility?

A

It is associated with connective tissue disease, diabetes, and neuropathy. This type of motility disorder causes failure of the Lower Oesophageal Sphincter mechanism, leading to heartburn and reflux symptoms.

Q

What is Achalasia?

A

it is the loss of myenteric plexus ganglion cells in the distal oesophagus and the Lower Oesophageal Sphincter. it is the failure of LOS to relax. Resulting in obstruction of the oesophagus.

Q

What are the risk factors of GORD?

Obesity
Drugs lowing LOS pressure
Smoking
Alcoholism
Hypomotility

16
Q

How can GORD be diagnosed?

A

It can be diagnosed on the basis of characteristic symptoms without diagnostic testing. ENdoscopy is a poor diagnostic test. However, endoscopy must be performed in the presence of alarming features that could suggest malignancy.

17
Q

State the aetiology of GORD

A

Could be due to a hiatus hernia or happen without any abnormality of the anatomy.

Without abnormality of the anatomy:
- increased the relaxation of the LOS
-Hypotensive LOS
-Delayed Gastric Emptying
-Decreased Oeosphageal acid Clearance
- Decreased Tissue Resistance to acid/ bile

Due to Hiatus Hernia:
- Anatomical distortion of the oesophageal junction

18
Q

Explain what happens in Hiatus Hernia

A

THe fundus of the stomach moves proximally through the diaphragmatic hiatus.

19
Q

State the two types of Hiatus Hernia

A

Sliding and Para-oeosphageal

20
Q

Explain the pathophysiology of GORD

A

The mucosa itself is exposed to acid-pepsin and bile. Which results in increased cell loss and inflammation. This causes erosive oesophagitis.

21
Q

State the complications of GORD

A

Stricture (8-15%)
Ulceration (5%)
Barrett’s Oesophagus
Carcinoma

22
Q

What causes Barrett’s Oeosphagus ?

A

It is caused by intestinal metaplasia related to prolonged acid exposure in the distal oesophagus.

23
Q

How would you describe Barrett’s Oesophagus?

A

A change from squamous to mucin-secreting columnar epithelial cells in the lower oesophagus. It is also a precursor to dysplasia/ adenocarcinoma. it has a risk of developing into oesophageal cancer.

24
Q

State the treatment for Barrett’s Oesophagus

A
  • Usually endoscopic Mucosa Resection (EMR)
  • Endoscopic Frequency Ablation
25
Q

State the treatment for GORD

A

Lifestyle Measures

Pharmacological:
- Gaviscon (Alginates)
-Ranitidine (H2RA)
-Omeprazole, Lansoprazole (PPI)

Anti-reflux surgery

26
Q

How can patients present with Oesophageal Cancer?

A
  • Progressive Dysphagia (90%)
  • Anorexia and Weight loss (75%)
    -Chest pain
    -Cough
    -Odynophagia
    -Pneumonia
    -Vocal cord paralysis
    -Haematemesis
27
Q

Where does squamous cell carcinoma occur?

A

The proximal and middle third of oesophagus

28
Q

What is the risk factor of squamous cell carcinoma?

A

Tobacco and alcohol

29
Q

Where does adenocarcinoma occur?

A

In the distal oesophagus

30
Q

What is squamous cell carcinoma associated with?

A

Achalasia, Caustic Strictures, Plummer Vinson Syndrome

31
Q

What is adenocarcinoma associated with?

A

Barrett’s Oesophagus

32
Q

Where can oesophageal cancer spread to?

A

Hepatic , brain, pulmonary ,bone

33
Q

How can we diagnose Oesophageal Carcinoma?

A

Endoscopy and Biopsy

34
Q

How do we stage oesophageal carcinoma?

A

Primarily CT Scan
Endoscopic Ultrasound
PET Scan
Bone Scan
The disease staging itself is TNM classification

35
Q

State the treatment for oesophageal cancer

A

The only potential cure is by oesophagectomy. This is usually preceded by chemotherapy. Very occasionally adjuvant therapy may be required.
Nutritional Support
Most patients have incurable diseases so are offered palliative treatment
(treat their swallowing difficulty). This is done endoscopically by means of inserting a stent, allowing the oesophageal to open up.

36
Q

What is Eosinophilic Oesophagitis?

A

A chronic immune condition. Symptoms of oesophageal dysfunction and pathologically by an eosinophilic filtration of the oesophageal epithelium.

37
Q

How do patients present with Eosinophilic Oesophagitis?

A

Dysphagia and food bolus obstruction

38
Q

What is the treatment of Eosinophilic Oesophagitis?

A
  • Topical/ swallowed corticosteroids
  • dietary elimination
  • Endoscopic dilation
