Hernia is an abnormal protrusion of
internal organs through an abnormal opening in the wall of the cavity.A
combination of increased pressure inside the body with weakness in the wall is
responsible for this condition.In this condition internal organs or parts of
organs are protruded out forming a swelling which will increase the size with
coughing and lifting weight,and while passing stool and urine.In lying down
position the swelling goes inside except in strangulated and irreducible
hernia.
Causes
1, Weakness in the body wall
a) Congenital weakness.
b) Acquired weakness due to injuries,wasting
of muscles,suppurative lesions in the wall and presence of weak natural
openings,obesity,lack of exercise,repeated pregnancy.
c) Surgical operation with improper suturing
or sepsis of operated site.
2) Increased pressure inside the body.
a) Chronic constipation.
b) Recurrent cough.
c) Weight lifting.
d) Stricture of urethra.
Common sites for hernia
Hernia can occure anywhere in the
body.However there are some common sites for hernia.Due to the presence of hard
bony covering chest wall is normally not affected.Hernia in the lower back is
also rare due to spine and back muscles and tough ligaments and sheeths.The
common site for hernia is abdominal wall.Compared to other parts the abdominal
wall is weak due to the presence of some natural orifices.There are some areas
wherein the abdominal muscles are weaker and thin and all these factors make a
chance for herniation.The common sites for hernia are following.
a) Inguinal hernia
Here the abdominal contents protrude through
the inguinal canal (passage in the lower abdominal wall just above the inguinal
ligament.It is seen on either side).This type is common in males.Initially the
swelling comes only while straining and goes back while lying down. Later the
large portion of intestine may come out which may not go back easily.
b) Femoral hernia
This type of hernia is more in females.Here
the abdominal contents pass through the femoral canal which is seen just below
the junction between the thigh and lower abdominal wall(Inside the femoral
triangle).The contents pass downwards and comes out through saphenous opening
in the thigh and forms a swelling under the skin.
c) Umbilical hernia
This is common in children.The umbilicus is
the weaker part of the abdomen.The contents of the abdomen may protrude as a
bulb like swelling while crying and defecating.
d) Incisional hernia
These hernias are seen in operated sites. Due
to improper suturing or sepsis the operated site becomes weak resulting in
hernia.
e) Epigastric hernia
Here the hearniation occures in the
epigastrium. It is a rare type.
f) Lumbar hernia
Here the hernia appear in the lumbar area on
either side of the lumbar spine(in the lumbar triangle).This is also a rare
type.
g) Obturator hernia
This is a rare type of hernia. Here the
contents pass through obturator foramen in the pelvic bone.
Complications of hernia
1) Strangulation
If the hernial orifice is narrow the
abdominal contents may not go back easily, and later the blood flow to the
herniated tissues may be blocked due to constricition.This can cause death of
protruded intestine.
2) Intestinal obstruction
This occures when the whole portion of the
intestine is protruded in to the hernial sac. The narrow hernial orifice will
block the passage of bowels.
3) Infection and peritonitis
If there is strangulation with death of a portion
of intestine there will be spread of infection to the abdomen resulting in
peritonitis.
Treatment of hernia
Initial treatment: In the initial stages of
hernia the following steps may be useful
1) Use of hernia belt
Special types of hernia belts are available
for each type of heania.This will prevent the protrusion and will reduce pain.
2) Constipation,recurrent cough,urinary
obstruction ect should be treated.
3) Fat reduction will increase the strength
of abdominal wall.
4) Abdominal exercises to increase the muscle
tone.
5) Take plenty of leafy vegetables, fruits
and fibrous diet for easy bowel movements.
6) Try other systems like Homoeopathy,Herbal
medicine and ect
If no relief by the above steps consult a
general surgeon for surgical management.
Surgical treatment.
The following operations are done depending
up on the type and nature of hernia.
1) Hertniotomy : In this operation the
contents of hernial sac is pushed in to the abdomen and neck of the sac is
ligated with transfixion ligature and the sac is cut off.
2) Herniorrhaphy : Here along with herniotomy
the posterior wall is repaired.
3) Hernioplasty : This operation is done if
herniotomy is not possible due to wide neck of the sac.Here the repair is done
with the healp of non absorbable materials like tantalum gauze,polypropylene
mesh or stainless steel mesh.
