1) Laparoscopic hernia repair is beneficial compared to open surgery because it causes minimal pain and allows patients to return to normal activities much quicker by avoiding large incisions and muscle cutting. 2) During laparoscopic hernia repair, small incisions are made and surgical tools and a camera are inserted to place a mesh over the defect from inside the abdomen, putting less strain on muscles. 3) Studies show laparoscopic hernia repair reduces post-operative pain and recovery time and has extremely low recurrence rates compared to open surgery due to how the mesh is securely placed from inside.

What is Hernia?
Hernia is a very common condition found in large number population throughout the world and
almost everyone is aware of its name if not exactly what it is. A hernia is in fact a defect in the
wall of tummy (abdomen). It commonly becomes prominent when the fat and intestines from the
tummy force their way out of this defect in the muscle and fat. Coming out of the tummy
contents through this defect causes a bulge (swelling) and sometimes pain in that particular area.
If not treated at time there is a danger of the intestine to get damaged (strangulated or
gangrenous). The problem increases with time and unfortunately the only treatment for this
condition is surgery. This traditionally involved a cut over the hernia, reduction of the contents
back to the tummy and some form of stitching of the defect to prevent the hernia from coming
back. This is what is called the repair of the hernia by open method or incision.
With the advent of instrumentations and technology the repair of hernia through laparoscopy has
rapidly gained popularity in the West. In this particular article I just want to discuss the benefits
of this technique that I have employed in hundreds of my patients with excellent resultsand
patient satisfaction. Earlier, most surgeons were even not of the opinion that Gallbladder should
be removed by laparoscope but now all agree that Laparoscopic removal of gall bladder is the
best way of treating gall stones and gall bladder disease.
Conventional Surgery or open hernia repair

2. This question is commonly being raised that if hernia repair surgery is being done for centuries
with good results by conventional surgery then why to complicate the issues with this new
technique? The main problem with a hernia operation is the average six weeks of rest after
surgery and the chance of the hernia coming back (failed operation that is known in medical
terms as a recurrent hernia). Detailed analysis at many centers has revealed that the recurrence
rate after open hernia repair is considerable. The large number of operations being done for
recurrent hernia confirms this. The techniques basically involve minimum stitching and a
tensionless placement of a net (mesh) at the defect site with little disturbance to the body
physiology. However all open surgical techniques involve cutting of the muscles overlying the
hernia in order to be able to reach the defect. Which in effect weakens already weak muscle
tissue?This like any other way of hernia repair means pain and rest after the operation.
Why laparoscopic treatment of hernia is more beneficial?
The Principle of Laparoscopic Hernia Repair
The basic difference and the concept of laparoscopic
repair of hernia can be explained by a simple
example. Imagine a bathtub. When you put the
rubber stopper at the outlet hole and fill the tub with
the water, the water pressure pushes the stopper in
place and keeps it fixed there. The more you fill the
water, the firmer will be the stopper. Now, if we
were to put the stopper from the outside. Then the
water pressure in the tub is going to push the stopper
out as the pressure increases. This is Pascal's law.
The same scenario can be imagined with placing a mesh on the hole where the hernia is. Is it
going to be better fixed from outside or inside? Open surgery places it from outside and
laparoscopic surgery places it from inside. Its will be more beneficial to fix it from inside. It is
because hernia develops whenever there is increase in the pressure inside the abdomen, for
example coughing, straining, constipation etc: Laparoscopically placed mesh placed from inside
can better cope with all such conditions that can cause recurrence of the hernia.
1. Fat being pulled in from the hernia defect
2. The defect as it looks from the inside
3. A mesh introduced like a rolled cigarette is being unrolled and
4. The mesh being fixed into place.

3. The Technique
During laparoscopic surgery, we make a small ½ inch cut in the skin at the belly button. Then a
cannula (thin tube) is introduced in between the muscle fibres without cutting any of the muscle.
Through the cannula, the laparoscope (camera) is inserted into the patient's body. It is equipped
with a tiny camera and light source that allows it to send images through a fibre-optic cord to a
television monitor. The television monitor shows a high resolution magnified image. Watching
the monitor, the surgeon can perform the procedure. While looking inside the patient, further two
½" diameter cannulas are put in. This way, the already weak muscles are not disturbed and the
net is placed through the half inch holes that are away from the hernia. Thus there is minimal
disturbance to the normal body physiology and as a result the pain is minimal and very little rest
is required. Also the hernia that is going out from the tummy is pulled back in rather than pushed
in from outside as is done in an 'open' operation. There are more and more reports now from
different studies across the world showing the success of this technique in reducing post
operative pain, rest and recurrence rates.
The greatest advantage of laparoscopic surgery for hernias is in patients of recurrent hernias
where the anatomy has already been disturbed and also in patients of hernias on both sides, as
they can be repaired through the same three holes avoiding any further pain or trauma.
The problem of the laparoscopic hernia repair is the cost of the operation, due to the expensive
imported instruments that are needed. The increased cost should be compared with the gain
associated by a quicker and more productive return to work by the majority of the patients.
Laparoscopic hernia is an efficient technique that compares favorably to current open surgical
techniques. Patients are relatively pain free following this procedure and can return to work and
normal activities much quicker than following conventional hernia repairs.
Frequently asked questions

4. Q. Why laparoscopy is better for treatment of hernia?
A. Because there is no large incision and cutting of muscles the patient experiences minimal pain
after the operation and get back to its normal activity quite early. Secondly, as the mesh is placed
in a secured way from inside the chances of the hernia coming back become extremely low.
Q. In how much time the patient get recovered from surgery?
A. The patient startsdrinking liquids soon after coming out of the anaesthesia which is about 2
hours after the operation. He can start eating soon thereafter and are allowed to get off the
bedand walk to the toilet to pass urine within four hours after the surgery. They are usually fit to
go home the same day or very next day. These patients can climb stairs and the majority can get
back to routine activity in 5 days.
Q. What are the chances of the hernia coming back (recurrence)?
A. If the operation has been performed properly the chances of hernia coming back are almost
negligible. This has been proved by many studies carried out so far.
Q. In patients with other medical problems like diabetes and blood pressure, is it feasible?
A. Yes it is. The absence of any major cuts to the body causes minimal disturbance to the
physiology. Also the early mobility and return to normal diet makes it easy for the body to
recover.
Q. Is there an increased risk of infection?
A. No. In the absenceof large incision the chances of wound infection are much less.
Q. Why do you approach the hernia from inside?
A. The hernia is protrusion of the body contents through the weakness in the muscle. It is logical
that something coming from inside is best dealt from inside. Also this way one does not cut and
weaken the already weak muscles at the hernia site.
Q. Is it a safe operation? How safe is it to leave a mesh inside the body?
A. This is an absolutely a safe operation and the mesh used is the same as the one used for open
operations over last 30 years. Therefore, its safety and efficacy is beyond doubt as proved by the
numerous trials in the USA and Europe.
Q. Is this an expensive operation?
A. As compared to open surgery the operative cost of laparoscopic surgery is more. This is
because the use of laparoscopic equipment and the imported ' one use only (disposable) '
instrument that is used to fix the mesh inside increases the cost of surgery. However, the
increased cost should be compared with the gain associated by a quicker and more productive
return to work by the patients and greatly reduced disruption of the routine life.
