Contents of the inguinal canal ‘rule of
3’s’
• 3 arteries: testicular, cremasteric and vas deferns • 3 nerves: genitofemoral, sympathetics, ilio inguinal nerve (only structure outside the spermatic cord and commonly damaged during repair) • 3 other: lymphatics, vas deferens, pampiniform plexus
Borders of the inguinal canal MALT:
• Roof = Muscle, internal oblique • Anterior wall = Aponeurosis external oblique (internal oblique lateral third) • Floor = Ligament, inguinal ligament • Posterior wall = Tendon, transversalis fascia and conjoint tendon
Femoral vs Inguinal Hernia
Fem - Lat and inf to pubic tubercule
Ing - Med and sup to pubic tubercule
Hernia?
Definition: protrusion of a viscus out of its cavity into an
abnormal position through a defect in the wall of the cavity.
What are the classical signs of bowel ischaemia?
- Acute severe abdominal pain
- Hypovolaemic shock
- Absence of abdominal signs

Child-Pugh Grading of Cirrhosis
- Albumin
- Bilirubin
- Clotting
- Distenstion - Ascites
- Encephalopathy
3 categories for each and up to 3 points for each.
>8 = significant risk bleeding
Exudate
due to inflammation causing increased capillary permeability
pneumonia, cancer, ai
transudate
due to increased hydrostatic pressure/ low plasma oncotic pressure
ccf, cirrhosis, nephrotic syndrome
TLS
high urate
high phosphate
high potassium
low calcium
renal failure
hydrate!!
high risk WBC>50 = rasburicase
mod risk WBC 10-50 = allopurinol
