Laparoscopic Hernias

Hernias

A hernia occurs when intestinal tissue protrudes through a weak point or tear in the abdominal wall, forming a sac. The protruding tissue may lose blood supply and become obstructed, resulting in serious health problems. Most hernias occur in the groin (inguinal, femoral), navel (umbilical) or at surgical incision sites (incisional).

Surgery is the only method to correct hernias. The most common hernia repair procedure is traditional (open) surgery. Usually done with local anesthesia, a large, deep incision is made through the muscle. The tissue is pushed back behind the muscle, which is then stitched closed, and plastic mesh is placed over the site for support. Full recovery takes four to six weeks.

The minimally invasive technique of laparoscopy, done under general anesthesia, involves the creation of three small incisions in the abdomen, the injection of carbon dioxide gas to create a "work space" and the use of a laparoscope, a thin instrument with a camera on the end allowing the surgeon to see inside the patient's. Other necessary surgical instruments are employed through the other small incisions. This method causes less trauma to the body, so post-operative pain is reduced and recovery only takes about a week.

In extra-peritoneal balloon laparoscopic hernia surgery, the "work space" is created with an inflatable balloon outside the abdominal cavity. This reduces the risk of bowel and blood vessel perforation associated with regular laparoscopic surgery. General anesthesia is still required and recovery takes about a week.
