When an organ or fatty tissue is squeezed through a hole (weak spot) in the connective tissue or a surrounding muscle then it causes a hernia. Usually, hernia happens at the abdominal wall and sometimes it can be seen as an external bulge.

There are various types of hernia which include:

  Inguinal Hernia (happens in the inner groin).
  Incisional Hernia (develops through a scar or an incision in the abdomen).
  Umbilical Hernia (develops at the belly button).
  Femoral Hernia (develops in the outer groin or upper thigh area).
  Ventral Hernia (develops in the general ventral or abdominal wall).
  Hiatal Hernia (develops inside the abdomen, beside the upper diaphragm or stomach).

The most common cause of hernia is the combination of pressure and opening of connective tissue or weakness of the muscle. Anything that escalates the abdominal pressure can lead to a hernia, including lifting heavy weights, constipation, persistent sneezing or coughing, obesity, and diarrhea. Overexertion, poor nutrition, and smoking can also weaken the muscles and can increase the possibility of a hernia.

Mesh Surgery 
Surgical mesh is used to supply extra support to the damaged or weakened tissue. It is a medical device, usually made out of either animal tissue (from skin or intestine) or synthetic material. Surgical mesh of synthetic material can be made in non-knitted sheet forms or in the knitted mesh. The synthetic material used for making a surgical mesh can be absorbable, non-absorbable material, or a combination of both.

Surgical mesh made out of animal tissue is disinfected and processed in a way that makes it suitable for implantation. These are absorbable and mostly made from the tissues of pig or cow.
Absorbable mesh degrades and loses its strength over time. It is not made to supply
long-term support to the restored site.

On the other hand, non absorbable mesh remains in the body for a long duration and is accounted for as a permanent implant. It provides permanent strength for restoring hernia.

In Hernioplasty or the mesh surgery for a hernia, the muscle opening is not stitched shut, instead it is covered with a sterile, flat mesh which is mostly made of synthetic or animal tissue. Small cuts are made around the hole in the shape of the mesh and the patch is stitched into the healthy surrounding tissues. The weak or damaged tissues around the hernia use the mesh, as support to regrow.

Recovery
Usually it takes up to 4 to 6 weeks to recover completely from mesh surgery. However, one can get back to his/her normal routine within 2 weeks post the surgery. There are certain precautions that one should undertake to avoid any complications. One should avoid heavy weight lifting, heavy exercises, stretching, and running. These precautions include diet modifications too. One should avoid consuming heavy fatty food and meat.

Takeaway
A hernia can be caused by a number of reasons and mesh surgery is a medical procedure helps to treat this problem. One should not avoid the treatment of hernia as the early treatment reduces the complications.

Mesh Surgery For Hernia - All You Must Know!

Laparoscopy surgery is a very vital component of the hernia repair. Studies have shown that many patients have a better outcome when they opt for laparoscopic surgery. Candidates eligible for this mode of surgery include those with bilateral inguinal hernias, ventral hernias, and recurrent hernia. People associated with athletics and other outdoor sports prefer to go for a laparoscopic hernia surgery as it ensures a speedy recovery and minimal tissue invasion (due to small incisions).

Laparoscopic hernia repair- inguinal
A laparoscopic surgery requires an incision of 1-2 cm at the belly (at the lower end). Two small punctures are done near the umbilicus. The punctures are done to make room for the cameras so that the surgeon is able to view the abdomen clearly. The smaller incisions allows the operating instrument to enter into the stomach.

The Procedure:
A balloon is placed in between the abdomen and the overlying muscle so that the peritoneum can be separated. When space is successfully made, the camera comes into the action to view the condition of a hernia. A hernia is pulled from its hole into the abdomen. Once the hole is detected, the defect of a hernia is fixed.

Laparoscopic hernia repair- incisional/ventral: Laparoscopic hernia repair is suitable for all types of a hernia such as an umbilical hernia, ventral hernia, recurrent umbilical hernia, epigastric hernia etc. Just like an inguinal hernia, A camera is placed into the abdomen through the muscles. Two small incisions are made for the operating instruments to get through. This is followed by the cutting of the tissue that is placed between a hernia and the intestine. The hole thus gets exposed. Through one of the laparoscopic ports, the hernia mesh gets rolled and is placed into the abdomen. A hernia is then pulled up and the mesh gets secured with 4 sutures. A special device is used to fix the healthy muscle.

Tension free repair: Tension free  repair is often used to symbolize hernia surgery. A hernia is often triggered by the weakened muscles. Few surgeons endeavors to sew the muscle around the area of a hernia. Since the muscles surrounding the hernia are weak in the first place, they pull apart causing a recurrence of a hernia. To avoid this, most surgeons use a mesh to strengthen the cells around the hernia region. This procedure ensures that the muscles aren t sewn but the mesh placed over the hole can prevent the muscle to push through the walls of the abdomen.

The use of mesh: There are some reservations about using the mesh in a hernia surgery. However, this is the safest and most appropriate way to perform a hernia laparoscopic surgery. The use of a mesh also negates the risk of open incisions and recurrence of a hernia.

Types of Hernia - How Laproscopy Can Help Manage?

A Hernia may be defined as the protrusion of an organ into an adjacent connective tissue or muscle. The protrusion usually occurs through a tear or a weakened area in the muscle (Fascia). Hernia can be an Inguinal Hernia, Umbilical Hernia, Hiatal Hernia or Femoral Hernia. It can also originate from an incision (Incisional Hernia).

The Inguinal Hernia is commonly observed in males. Here, the intestine squeezes through a tear in the abdominal wall into the groin (Inguinal canal). At times, the small intestine bulges through the abdominal wall (weak spot) near the belly button, which results in Umbilical Hernia. In Hiatal Hernia, the upper part of the stomach passes into the chest through the diaphragm, and of all the hernia types, the Inguinal Hernia is the most common.

Severe strain and muscle tear or weakness can result in Hernia. Obesity, chronic constipation, chronic coughing and sneezing, ageing, damage caused by injury, medical conditions like Cystic Fibrosis, contribute to increased incidences of Hernia. In case of Hernia, the affected area tends to protrude or bulge out. If left untreated; Hernia can prove to be detrimental. One needs to consult a physician for proper diagnosis and treatment. Physical examination can help in the diagnosis of Inguinal Hernia. An ultrasound is needed to diagnose Umbilical Hernia. A Barium X -ray or endoscopy can be of great help in the diagnosis of Hiatal Hernia.

The severity of the Hernia depends upon its size. In case the Hernia is rapidly increasing in size, a surgery is needed for the repair. The surgery performed can be open or laparoscopic. In open surgery, Hernia is identified through an incision. Once located, the Hernia is removed from the adjacent tissues. In laparoscopic repair, small incisions are made in the affected region. Through these incisions, specialized instruments are inserted. It is through these instruments that the surgeon visualizes and performs the surgery.

In such repairs, a mesh, held in place by sutures is used as a scaffold. This facilitates the growth of new tissues in the affected person. This technique significantly lowers the chance of a recurrence. Certain factors must be well addressed, before performing a Hernia operation:

* Hernia operations, laparoscopic in particular, should be performed by experienced surgeons. Inexperienced surgeons will do you more harm than good.
* Laparoscopic Hernia operation should be avoided in case a patient has adhesions from previous surgery.
* Extreme care should be taken while performing a Hernia operation in infants and children.
* In some cases, Hernia surgery might affect or injure the vas deferens in men. This in turn can affect fertility in men.

What To Know About Hernia Operation

Hernia are bulges protruding form a weak point on belly (abdomen) through which intestine and abdominal fat comes out to lie just below the skin. It can also be found in groin, upper thigh and chest. There are several types of hernia like inguinal hernia (direct and indirect), femoral hernia, umbilical hernia, umbilical hernia, epigastria hernia and incision hernia.

Who get hernia?

Conditions that lead to increased abdominal pressure are at more risk of developing hernia  

o Persistent cough

o Being overweight or pregnant

o Lifting, carrying or pushing heavy loads

o Straining on the toilet

What are the symptoms of hernia?

o Mostly they are asymptomatic/ no symptoms.

o People just notice a swelling or bulge which gets bigger while standing or straining and disappear while lying down/sleeping.

o Some might feel a dragging/aching sensation.

o The swelling tends to get bigger with time.

o Symptoms develop when there is a complication like strangulation. This happens when the content of abdomen (intestine) come out and can not go back. There will be severe pain in the region and vomiting. Overlying skin will become red. Urgent surgery is needed in this situation otherwise the blood supply to intestine gets cut-off and the intestine in hernia might die (gangrene).

How are hernia treated?

Surgery is the only treatment for hernia. Now a days, most of the hernias are operated laparoscopically (key hole or minimally access technique)

Minimally Invasive Hernia Repair - The surgery is done with a laparoscope which has a small tiny camera, hernia mesh and small tool with it. So the patient can return back to their normal routine earlier as the incision made is smaller.

Advantages of Laparoscopy:

Laparoscopy has clear advantage over open repair in the way of less pain, less complications like wound infection, small and more cosmetic scar, shorter hospital stay, early return to work and daily activities and less chance of recurrence (repeat formation of hernia after surgery).

Before undergoing hernia surgery:

* One week before surgery it is much essential to stop taking drugs that are causing the thinning of the blood. Drugs like Clpodogrel and Acitrome or Warfarin should be stopped with the doctor s advice. 
* Stop herbal supplements and check the fitness of your cardio and diabetes. 
* Gain adequate knowledge about surgery and be prepared for post surgical care.

After hernia surgery:

* Avoid heavy weight lifting, exercises, and physical works with excessive strain a few weeks after surgery 
* Cough or laugh loud only with support to the surgical site until one week after surgery

DO s & DON T s in patients of Hernia:

DO s:

1. Increased intake of fibers in diet. ( Fruits, vegetables and grains)

2. Drink plenty of water and other fluid to prevent constipation.

3. Exercise regularly: sweat and loose excess weight and toxins.

4. Eat small meals more frequently in place of one or two large meals

DON T s:

1. Stop smoking and drinking

2. Don t reduce the amount of food you eat

3. Avoid lying down or bending after meal

4. Avoid wearing tight clothes

5. Avoid food difficult to digest

6. Avoid strenuous activities like heavy weight lifting

Types of Hernias:

Incisional hernia:

This happens at the site of previous surgery. This occurs as a result of poor wound healing at the time of previous surgery or as a result of complications like in infection. It is rare after laparoscopic or key hole surgery.

Umbilical hernia:

This occurs through or around belly button (umbilicus). It can be present at the time of birth and needs no repair as most of them resolve by the end of one year. If it persists or appears after 5 years of age then operation is required.

Inguinal hernia:

These are most common hernias and occur in groin region. They are more common in men.

All You Need To Know About Hernia!

The liver has a significant role to play in metabolism and digestion. The failure of a liver can lead to significant health issues. There are some causes for liver failure, which cannot be treated with medications. In these people, a transplant, which is replacing the diseased or injured liver with another liver, is the only definitive treatment option.

Some conditions which can require a liver transplant are:

Severe cirrhosis with a life expectancy of less than a year
Severe liver failure
Non-alcoholic steatohepatitis (NASH)
Liver cancer
Chronic hepatitis C
Biliary atresia in children
Types of transplant:

Living donor transplant: In some patients, partial liver can be removed from a close family member and transplanted into the affected individual. The liver is known for its regeneration ability, and over time, will grow in the recipient.
Cadaveric transplant: Immediately after death, a liver can be removed and transplanted.
While the concept of a transplant sounds quite convincing and appealing for those with a severe liver disease, it is also important to note that not all would qualify for a liver transplant. The conditions which would disqualify a recipient are discussed below:

Significant heart disease: Those with severe coronary artery disease, valvular disease, cardiomyopathy, aortic stenosis, and cardiomyopathy are not candidates for a liver transplant.
Severe lung disease: Those with poor lung perfusion do not qualify for a liver transplant.
Advanced age: Greater the age, lesser the survival rates. So, people aged more than 70 are usually not considered for a transplant.
Obesity: A person with a BMI of more than 35 is often not a good candidate for a transplant. The overall health should be managed in these people.
Malnutrition: On the other extreme, severely malnourished individuals are also not considered for a transplant.
HIV infection: A person who is HIV-infected does not qualify for a liver transplant.
Substance abuse: Anyone who is actively abusing alcohol and/or substances is definitely removed from the list for a transplant.
Metastasis: If a patient is looking for a liver transplant due to hepatic cancer, it is essential that the cancer is contained. If it has spread to various parts, then containing it would be difficult, and a transplant may not succeed.
Multisystem organ failure: Other than heart and lungs, even people with poor renal function are not ideal candidates for a liver transplant.
A detailed liver recipient evaluation assessing the severity of liver disease, chances of survival, and overall health are done before a person is listed for liver transplant. This evaluation ensures a better success rate with the transplant.

Common Surgical Complications That One Should Be Prepared For?

A hernia occurs because of an internal weakening of the abdominal layer, resulting in tearing. The inner most layer of the abdomen forms a sac and pushes the weakening area. This results in the abdomen tissue being slipped into the sac, causing pain and other health problems. It can occur to both men and women. Apart from natural weakness of the abdomen, a hernia can get triggered from heavy weight lifting, constant coughing, gaining weight and from irregular bowel movement. 80percent of hernia cases originate near the groin.

What are the symptoms?
Some of the common symptoms of a hernia include:

Constipation
Nausea
Feeling of fullness even without eating a thing
Sharp pain while lifting weight
Burning sensation
Dull ache near the groin area
Bulge near the groin area
How is a laparoscopic hernia performed?
This mode of surgery uses a telescope-like instrument known as the laparoscope. With the help of a small incision, the laparoscope is inserted at the belly button. Since the procedure is performed withanaesthesia, it isessential for a doctor to do a routine medical check-up that evaluates the general health of the patient, past medical history, EKG, blood work etc.

Usually, the patient doesn t feel a thing while the surgery is performed. A video camera is connected to the instrument to get a detailed inside view of a hernia and the area that needs to be repaired. Before this, the abdomen is inflated with the help of carbon monoxide. A mesh is placed inside the abdomen to fix the defects of the abdominal wall and strengthen the weakened tissue of the abdomen. Once the procedure is done, the incisions that are made in the abdomen is closed with the help of surgical tapes. The mark of incision disappears within a month.

Benefits of Laparoscopic Hernia Surgery
The benefits of laparoscopic surgery are quite evident.

A lot of tiny incisions are made rather than making a large incision in the abdominal area. This ensures speedy recovery and a short stay at the hospital.
The pain is significantly less compared to the conventional surgery.
The cost of a laparoscopic surgery is lesser
Lastly, a speedy recovery can ensure that a person can return to work within a few days after the surgery is performed.
What to expect after the surgery
Doctors often suggest a week of complete rest after the surgery. The healing time can vary from person to person. A surgeon typically prescribes antibiotics and pain medications to cope up with the wound and pain. It must be ensured that these medicines are taken on time. A revisit to the surgeon might be required after a couple of weeks to assess the recovery.
