Q

What cancer can GORD predisposed to and why is this?

A

Oesophageal cancer either Adenocarcinoma or squamous cell

because the gastric contents of the damages the mucosal epithelial cells and causes oesophagitis

Q

Describe the pathophysiology of systemic scleroderma?

A

Has a strong genetic component and immunological components (ANA positive in 90%)

immune system activation leading to endothelial cell activation and damage of the endothelium

fibroblasts because increased collagen deposition

activated T cells promote disease by making for pro fibrotic cytokines and down regulating the inhibitory cytokines

coagulation profile (assesses function of liver but also risk a bleed)
hepatic venous pressure gradient (assesses portal hypertension)
blood type and crossmatch (in case of life-threatening bleed)

you should also attempt to find the cause of the cirrhosis of this has not been established:
serum LFTs ( AST ALT Alk Phos Billi all ++)

Q

what is an ileus?

A

The slowing of GI motility accompanied by distension in the absence of mechanical obstruction

182
Q

What causes ileus?

A
It is something which occurs in response to physiological stress such as:
surgery 
sepsis 
metabolic derangements
GI diseases
183
Q

What risk factors are associated with developing an ileus?

A
Abdominal surgery
acute or systemic illness:
 sepsis
MI
pneumonia
trauma
metabolic derrangements
184
Q

What is the presentation of an ileus?

A

Similar to that of obstruction but without its clinical features on examination

nausea and vomiting
abdominal distension
constipation
discomforts
abdominal cramping
decreased or hypoactive bowel sounds

BUT.. no features of mechanical obstruction such as peritoneal inflammation, hernias, rebound tenderness

185
Q

What is the diagnosis of an ileus?

what other investigation may you like to perform?

A

It is a diagnosis of exclusion of obstruction

abdominal x-ray is diagnostic (showing no specific gas pattern and diffuse distension)

Full blood count - rule out infection

186
Q

What differences would you see on x-ray for an obstructed bowel versus an ileus?

A

Obstructed bowel will have little to no air distal to the obstruction whereas an ileus will have a diffuse non-specific gas pattern

187
Q

What is the management of an ileus?

A

Nil by mouth and IV fluids

NG decompression if there is significant vomiting or distension

parenteral nutrition if symptoms lasting more than three days

188
Q

What is peritonitis?

A

inflammation of the peritoneum

189
Q

What can cause peritonitis?

A

Perforation of the GI tract - most common
local or systemic infection
leakage of non-infectious bodily fluids- blood gastric juice pancreatic enzymes (pancreatitis)

190
Q

What is spontaneous bacterial peritonitis?

A

Inflammation of the peritoneum caused by leakage of infected ascitic fluid due to end stage cihrossis

191
Q

What are the symptoms of peritonitis?

A
Abdominal pain
Guarding
rigidity
rebound tenderness
fever
tachycardia
altered mental state
192
Q

What features does spontaneous bacterial peritonitis have that peritonitis does not have?

A

Spontaneous bacterial peritonitis Has all the same symptoms as normal peritonitis but with additional signs of ascites cirrhosis and diarrhoea caused by intestinal hyper mobility

193
Q

What is the management of peritonitis?

A

Broad-spectrum antibiotics e.g. cephalexin or laparotomy

194
Q

What investigations is it important to carry out in spontaneous bacterial peritonitis?

A

Check LFT And PT/INR
Ascitic fluid analysis gram staining culture – diagnostic
