A hernia is an abnormal protrusion, or bulging out, of part of an organ through the tissues that normally contain it. A hernia may develop in almost any part of the body; however, the muscles of the abdominal wall are most commonly affected. In this condition, a weak spot or opening in a body wall, often due to laxity of the muscles, allows part of the organ to protrude. Hernias by themselves usually are harmless, but nearly all have a potential risk of having their blood supply cut off (becoming strangulated). If the hernia sac contents have their blood supply cut off at the hernia opening in the abdominal wall, it becomes a medical and surgical emergency. There are many different types of abdominal wall hernias. They are:
All newly discovered hernias or symptoms that suggest that one might have a hernia, should prompt a visit to the doctor. Hernias, even those that ache, if they are not tender and easy to reduce (push back into the abdomen), are not surgical emergencies, but all have the potential to become serious. If one has an obvious hernia, the doctor will not require any other tests (if the person is healthy otherwise) but may diagnose by just examining the patient. This means that the doctor will ask the patient to cough or stand. This increases the intra-abdominal pressure and forces the hernia to bulge out.
Although non-operative treatments existed in the past, they proved to be ineffective, so surgery is currently the primary treatment for all hernias. The treatment of every hernia is individualized, and a discussion of the risks and benefits of surgical versus non-surgical management needs to take place. One will be surprised to know that herniorrhaphy is one of the Top 10 surgeries performed in the United States alone.
For most people who develop a hernia, it is always advisable to see a doctor, even if there are no symptoms other than the protrusion. In order to reduce the risk of future strangulation, the doctor may recommend surgery which is called herniorrhaphy. There are two basic methods which are followed. They are:
The surgery to remove the gallbladder is called a cholecystectomy. The gallbladder is removed through a 5 to 8 inch long incision, or cut, in your abdomen. The cut is made just below your ribs on the right side and goes to just below your waist. This is called open cholecystectomy.
A less invasive way to remove the gallbladder is called laparoscopic cholecystectomy. This surgery uses a laparoscope (an instrument used to see the inside of your body) to remove the gallbladder. It is performed through several small incisions rather than through one large incision.
Repair of simple and complex abdominal hernias by the laparoscopic technique is now the method of choice in many centers. Laparoscopic repair offers equivalent outcomes to open repair, with the additional benefits of greater patient satisfaction and reduced hospitalization. For some hernias, like incisional, the outcome appears to be superior using the minimally invasive technique. Laparoscopic hernia repair is similar to other laparoscopic procedures. This type of operation is done using a tiny telescope called a laparoscope. It is linked to a special camera. The device allows the doctor to see the hernia on a video screen. It requires smaller incisions (usually 1/5 to 1/2 of an inch). The laparoscopic approach to both inguinal and ventral hernias has resulted in a reduced hospital stay and faster recovery time.
