Q

3 investigations for reflux?

A
  • Endoscopy
  • Barium swallow (much less likely to do this)
  • Oesophageal manometry and pH studies (put probe down and when you get acid in your oesophagus it will register this, probe stay there for 24hrs)

Q

Management of dyspepsia/ patient complaining of indigestion?

A

Consider other organs
If predominant heart burn manage as GORD
If it is true dyspepsia then check for alarm symptoms: dysphagia, weight loss, GI bleeding, persistent vomiting, unexplained weight loss, upper abdominal mass
If there are no alarm symptoms can manage as functional dyspepsia and give lifestyle advice if alarm symptoms make relevant referral.

A

A break in the superficial epithelial cells penetrating down to the muscularis mucosa of either the stomach or the duodenum, there is a fibrous base and an increase in inflammatory cells

Q

Clinical features of peptic ulcers?

A

Recurrent burning epigastric pain. Anorexia and weight loss may occur.
Gastric ulcers tend to have worse pain when eating and duodenal ulcer pain tends to be relieved by eating.

Q

Describe H pylori infection and how it relates to gastric disease

A

This is acquired in infancy
The majority of people have no pathology
Some develop ulcers
Even smaller amount get cancer

25
Diagnosis of H. Pylori?
* gastric biopsy and do urease test, histology or culture * urease breath test * FAT (faecal antigen test) * serology (IgA antibodies) - not accurate with increasing patient age
26
Treatment of peptic ulcers?
Patients that are H. Pylori positive should have eradication therapy- this involves antibiotics and PPIs PPI + amoxycillin 1g bd + clarithromycin/ metranidazole 500mg bd PPI + metronidazole 400mg bd + clarithromycin 250mg bd (if pen allergic) If H. pylori negative go on antisecretory therapy- PPIs With gastric ulcers there is follow up at 6-8 weeks to ensure healing and no malignancy
27
Achlorhydria increases risk of __________and this is absence of hydrochloric acid in secretions
gastric cancer
28
Cardinal features of an acute upper GI bleed are?
haematesmesis (vomiting of blood) and melaena (the passage of black tarry stools the colour due to blood altered by passage through the gut)
29
What is the most common cause of serious and life threatening upper GI bleeding?
Peptic ulcer
30
Emergency endoscopic treatment of peptic ulcers?
1. Injection 2. Heater probe coagulation 3. Combinations 4. Clips 5. Haemospray
31
What are varices? Explain acute variceal bleeding
Varices are dilated blood vessels in the esophagus or stomach caused by portal hypertension. If they rupture they will bleed Complication of liver failure
32
When do you suspect someone with varices with an upper GI bleed?
Known history of cirrhosis with varices History: chronic alcohol excess, chronic viral hepatitis infection, metabolic or autoimmune liver disease, intra-abdominal sepsis/surgery
33
Oesophageal tumours risk factors?
High levels of tobacco for both Alcohol more for squamous Adeno is associated with Barretts and therefore reflux
34
What part of oesophagus do squamous cell carcinomas and adenocarcinomas affect?
Squamous affects mainly the upper oesophagus | Adenocarcinoma affects mainly the lower oesophagus
35
Presentation of oesophageal cancer?
``` Progressive dysphagia Pain from impaction of food, more persistent pain may imply invasion of surrounding structures Weight loss Anrorexia Lymphadenopathy ```
36
Investigations that can be done for oesophageal cancer?
Endoscopy to obtain biopsy | Barium swallow allows you to rule out other diagnoses such as achalasia
37
Treatment for oesophageal cancer?
Surgery is the best option but should only be used when imaging shows the tumour has not infiltrated outside the oesophageal wall. Some patients are given preoperative chen-radiation therapy. Often palliative therapy is the only option. It is important that patients are given nutritional support.
38
Risk factors for gastric carcinomas?
H. pylori infection Dietary factors Tobacco smoking Genetic abnormality
39
Presentation of gastric carcinomas?
Often presents late as can be quite asymptomatic Epigastric pain similar to peptic ulcers Predominant symptom is usually weight loss May also get nausea and get dysphagia if the tumour is in the funds May only get symptoms of spread e.g. malignant ascites
40
What investigation can be done to diagnose gastric carcinoma?
Gastroscopy
41
Treatment for gastric carcinoma?
Non-ulcerated mucosal lesions can be removed endoscopically Surgery is the most effective form of treatment and may be combined with chemotherapy May need palliative care and relief of symptoms
42
What do you inject into bleeds and why?
Dilute adrenaline- will cause vasoconstriction
43
What is involved in dual therapy treatment of GI bleeds?
Injection of dilute adrenaline and heater probe treatment
44
Bleeding peptic ulcer management plan?
Adrenaline – heater probe therapy If bleed stops give IV omeprazole and potentially H. Pylori eradication If they re-bleed give omeprazole with further endoscopic intervention. If this fails then they need surgery.
45
Risk factors for variceal bleed?
- portal pressure > 12mmHg - varices > 25% oesophageal lumen - presence of red signs - degree of liver failure (Child’s A
46
Treatment for variceal bleeding?
1. Terlipressin (vasopressin analogue)- in everyone 2. Endoscopic variceal ligation (banding) 3. (Sclerotherapy) 4. Sengstaken-Blakemore balloon 5. TIPS Secondary treatment involves banding and propranolol
47
Are peptic ulcers more common in old or young people?
Old people as sanitation was poorer when they were younger so they are more likely to be infected with H. Pylori
48
What allows helicobacter to infect the duodenum?
Gastric metaplasia that occurs in the duodenum to increased acid
49
5 causes of dysphagia?
``` Candidiaisis (white patches on mouth that don't wipe away) Neuromuscular disorders (bulbar palsy) Oesophageal motility disorders (spasm or achalasia) Extrinsic pressure (mediastinal glands or enlarged LA) Intrinsic lesion (stricture benign or malignant, webs, foreign bodies, pharyngeal pouches) ```
50
Palliative treatment for oesophageal cancer?
Endoscopic dilation
51
Treatment of achalasia?
Balloon dilation or myotomy (cut away part of stomach)
52
Barium swallow of oesophageal spasm will show?
cork screw oesophagus
53
First line investigations for most oesophageal disorders?
gastroscopy
54
Manometry is done when
you can't get diagnosis from endoscopy, this looks at motility
55
Oesophageal dysplasia is managed by?
radio frequency ablation
56
Peptic strictures are surgically managed by?
endoscopic dilation
57
Surgical management of gord is?
Nissen fundoplication
58
If someone has dysphagia more for liquids than solids what should you think?
More likely to be a motility issue as opposed to a physical obstruction
