Open Inguinal Hernia Repair
In open hernia repair, also called herniorrhaphy, a person is given local anesthesia in the abdomen or spine to numb the area, general anesthesia to sedate or help the person sleep, or a combination of the two. Then the surgeon makes an incision in the groin, moves the hernia back into the abdomen, and reinforces the muscle wall with stitches. Usually the area of muscle weakness is reinforced with a synthetic mesh or screen to provide additional support, an operation called a hernioplasty.
