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)



 Note: last 2 signs may be absent if constricted at
 the neck

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

Examination of the hernia
      • Ask permission

      • Exposure

      • Position

      • Third party

      • Privacy

      • Manner


7/31/2012                         21
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


7/31/2012                                                    22
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”



7/31/2012                                        23
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




7/31/2012                                                   24
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.


7/31/2012                                                             25
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 …)



7/31/2012                                                           26
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



7/31/2012                                     27
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


7/31/2012                                                 28
Percuss and auscultate
   • Intestine = resonant and audible bowel sound




7/31/2012                                     29
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




7/31/2012                                                   30
Examine the abdomen

     • Any possible increased intra-abdominal

            pressure

               e.g ..????




7/31/2012                                       31
Cardiovascular & respiratory assessment

 • Fitness

 • Any chronic respiratory problem..

 • Increased intraabdominal pressure

Any age but common in young                   Elderly
Via deep inguinal ring and long the           Via transversalis fascia (hasselbach’s

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            Impulse on middle finger

Clinical features

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

D/Dx of inguinal hernia???

    • Femoral hernia

    • Vaginal hydrocele

    • Hydrocele of cord or canal of nuck

    • Undescended testis

    • Lipoma of cord




7/31/2012                                  36
Some definition ?????

  • Strangulated hernia ?

  • Richter`s hernia?

  • Maydl`s hernia?

  • Sliding hernia?

  • Incarceration ?
