4. What is hernia?

5. Hernia – protrusion of a viscous or part of
viscous through an abnormal opening in the
walls of its containing activity.

OCCUR?

8. Composition of hernia
Sac
• Sac is a
diverticulum of
peritoneum
• Consist of
mouth,neck,
body and
fundus
Covering
• Derived
from the
layers of
abd wall
through
which the
sac passes
Contents
• Omentum- omentocele
• Intestine- enterocoele
• Portion of circumference of
intestine- Richter’s Hernia
• Portion of bladder (or a
diverticulum)
• Ovary with or w/o
corresponding Fallopian
tube
• Meckel’s diverticulum-
Littre’s hernia
• Fluid

9. Classification

10. Reducible Hernia-
contents can be
returned to abdomen
Irrreducible Hernia-
contents cannot be
returned to the
abdomen but there is
no other complication
Obstructed Hernia-
irreducible hernia
containing intestine
that is obstructed with
good blood supply
Strangulated Hernia-
blood supply is
obstructed
Inflammed Hernia-
contents of the sac
become inflammed

11. Basic features of hernia???
• Occur at weak point (Congenital or acquired)
• Reducible on lying down or with direct pressure
• Have an expansile cough impulse
(Visible & palpable)
4/21/2015 11
Note: last 2 signs may be absent if constricted at
the neck

12. Causes of abdominal Herniae
Anatomical weakness
• Structures passing through
the abdominal wall
• Muscle fail to develop
• Scar tissue
Acquired weakness
• Trauma
• High intra-abdominal
pressure
• Coughing
• Straining
• Abdominal distension

13. Various types of Herniae?(common)
• Inguinal
• Umblical
• Incisional
• Femoral
• Epigastric
4/21/2015 13

14. • Spigelian
• Obturator
• Lumbar
• Gluteal

18. Relation to the surrounding
structures
1.Anterior wall
Medially-external obliqueaponeurosis
Lateral- internal oblique muscle
2.Posterior wall
Medially – strong conjoint tendon
Lateral- fascia transversalis
3.Floor
Medial- Lacunar ligament
Lateral- inguinal ligament
4.Roof
Arching of fibers of int oblique and
transverse muscles.

21. Examination of the hernia
• Ask permission
• Exposure
• Position
• Third party
• Privacy
• Manner
4/21/2015 21

22. Ask the patient to stand up
• Lying position …..why not?
Not possible to see the true size.
proper examination even not detect at all.
• If suspect since early,start with standing position
• If found during routine abdominal exam, complete
abd exam first and ask the patient to stand up to
examine properly.
NOTE: examine both inguinal regions
4/21/2015 22

23. Look at the swelling from the front
• Exact size and shape
• Visible expansile cough impulse
• Distinguish from femoral hernia
• Extend of lump…down into the scrotum ??
• Other scrotal swelling ….
• Any other swelling on the “normal side”
4/21/2015 23

24. Feel from the front
• Exam the scrotum and content
• First whether inguino-scrotal or true scrotal by
getting above the upper edge ( get above )
• Don’t exam the external ring or canal as it is
painful
4/21/2015 24

25. Feel from the side
• Having exam the scrotal content & can’t get above the lump –
assuming the inguinal hernia – proceed to examination of the
lump…….??? Inguinal Hernia examination
• Stand at the side of the patient –same side of hernia
• Place on hand at the back of to support the patient
• Examinating hand and fingers parallel to the inguinal ligament.
4/21/2015 25

26. Expansile cough impulse
• Firmly compress the lump with fingers
• Ask the patient to turn head toward to opposite side &
to cough
• If Tense and expansile = cough impulse (+)
Note:
• Localized swelling in the spermatic cord and undescended testis
come out during cough but not bigger nor tense .
• (+) is diagnostic for hernia
• (-) can not exclude diagnosis (e.g adhesion …)
4/21/2015 26

27. Is the swelling is reducible?
• Position????
• Can control at internal ring =indirect
• Can not control = direct
Note:
• Reduction point to pubic tubercle
• above and medial … inguinal
• Below and lateral …….femoral
Only for reducible one
4/21/2015 27

28. Remove the finger and watch the
reappearance
• Direction and the way reappearance help to deduct the
origin of hernia
• Obliquely downward = indirect
• Directly project forward = direct
NOTE:
Difficult in obese patient
4/21/2015 28

29. Percuss and auscultate
• Intestine = resonant and audible bowel sound
4/21/2015 29

30. Feel the other side
• Move the other side and exam the inguinal region
• Commonly bilateral particularly in direct inguinal hernia
• Ask the patient to cough to make obvious small bulge
4/21/2015 30

31. Examine the abdomen
• Any possible increased intra-abdominal
pressure
e.g ..????
4/21/2015 31

32. Cardiovascular & respiratory assessment
• Fitness
• Any chronic respiratory problem..
• Increased intraabdominal pressure
4/21/2015 32

33. Differences b/t
direct and indirect inguinal hernia
4/21/2015 33

34. Indirect inguinal hernia Direct inguinal hernia
Any age but common in young Elderly
Via deep inguinal ring and long the
inguinal canal
Via transversalis fascia (hasselbach’s
triangle)
Patent or reopen processus vaginalis Weak abdominal wall/muscle
Unilateral in 2/3 case (right side more
common)
Bilateral in > ½ case
Enter scrotum (complete) Does not enter scrotum (incomplete)
Reduced by patient/doctor (manually) Reduced on lying down (automatically)
Narrow neck- more liable to strangulate Broad neck
Zieman technique- impulse on index
finger
Impulse on middle finger
Deep ring occlusion test- control Bulge out
Little finger invagination test- impulse on
finger tip
Impulse on pulp
4/21/2015 34

35. Clinical features
Indirect inguinal hernia
- sudden pain at the groin
- swelling in inguinal canal which
may extend into scrotum
- become visible when patient
stand or cough
- dragging/ discomfort
- passes above and medial to
pubic tubercle
- palpable cough impulse
- audible bowel sound +/-
Direct inguinal hernia
- seen protruding directly forward
- usually readily reducible
- gradual onset
- Severe pain is rare If there is no
complication such as incarceration or
strangulation
4/21/2015 35

36. D/Dx of inguinal hernia???
• Femoral hernia
• Vaginal hydrocele
• Hydrocele of cord or canal of nuck
• Undescended testis
• Lipoma of cord
4/21/2015 36

37. Some definition ?????
• Strangulated hernia ?
• Richter`s hernia?
• Maydl`s hernia?
• Sliding hernia?
• Incarceration ?
