1
Definiteion of a hernia
An abnormal protrusion of a viscus outwith its normal body cavity
2
What is the most common type of hernia
Inguinal
3
How might abdoninal wall hernias arise?
From natural opening or weak areas, caused by stretching or sirgical incision
4
Name some predisposing factors for abdominal hernias?
Heavy lifting
Coughing
Constipation
Prostatism – commonly bilateral inguinal
Pregnancy
Obesity
5
What do predispising factors for abdominal hernias all have in common?
They raise the intraabdominal pressure
6
How can we classify hernias?
Reducible (going back in and flatten) or irreducible (may obstruct)
7
What happens to the contents of an irreducible hernia?
May become incarcerated or strangulated
8
What is strangulation and describe the appearance
It denotes compromiseof the blood supply of the contents
and its development increase morbidity and mortality
Purple looks like its going to burst
9
Name some of the causes of incisional hernias
Age
Obesity
general debiliility
Post op wound infection
post op haematoma
raised intra abdominal pressure
10
What type of hernias do children get
True umbilical hernias
11
What type of hernias do adults get?
Para - umbilical hernia
12
What treatment do we give for umbilical hernias
If the defect is very small, we can put some stitches in it
More than 2cm then we need some mesh in place to firm up the area
13
What age group of people are prone to epigastric hernia
Teenagers - mid 20s usually males
14
What do we do for umbilical hernias for under 3 year olds
Leave them - they usually resolve themselves
15
If the child is more than 3 and the hernia has not resolved, what do we do?
Operate
16
What is the risk of an inguinal hernia in a child
What do we do for inguinal hernias
Obstructing or strangling the bowel
Operate in the next couple of months unless obstructing or strangling the bowel
17
What causes hernias in kids?
Potent Processus Vaginalis
18
What side is a hernia more common in?
Right
19
What is a Herniotomy
Where you cut off the hernia
20
Who is most likely to get a femoral hernia
Thin elderly female
21
What is the main symptom for a femoral hernia?
Loss of groin crease
22
Describe the anatomy of the femoral hernia
Defect through the femoral canal
below and lateral to the pubic tubercle
Usually flatten the groin crease
23
How much more likely is it that a female wil develop a femoral hernia?
10 times more likely
24
Describe the anatomy of an inguinal hernia
Above pubic tubercle - increases the groin crease
25
If you can feel above the scrotal swelling? what is the most likely diagnosis?
epididymal cyst
ie. not a hernia
26
Name 4 causes of scrotal swellings
Inguino-scrotal hernia (indirect)
hydrocoele
Epididymal cyst
Testicular swelling
27
How do you examine a patient for an inguinal hernia?
Examine the patient upright
Find the pubic tubercle - above and medial = inguinal.
below and lateral = femoral
Ask the patient to cough
28
how do you differentiate clinically between indirect and direct inguinal hernias?
Pressure over the deep inguinal ring get patient to cough
Place the little finger in the canal
29
How do you differentiate at operation between direct and indirect inguinal hernias?
Medial to inferior epigastric vessels = direct
Lateral to inferior epigastric vessels = indirect
