Laparoscopic surgery
Many hernia repairs can now be performed through Laparoscopic surgery. The surgeon uses a special viewing instrument called a laparoscope, inserted through a small incision in the abdomen. The laparoscope is like a tiny video camera that gives the surgeon a clear view of the abdominal area. Other small incisions are made to insert the surgical instruments used to push the intestine into place and repair the abdominal wall. The surgeon may use a procedure called hernioplasty to reinforce the entire inguinal area with synthetic material, like a tire patch. Laparoscopic hernia surgery can be performed on an outpatient basis. Incarcerated and strangulated hernias require emergency surgery and hospitalization. Laparoscopic surgery may not be recommended for very large hernias.
