A hernia exists where part of the abdominal wall is weakened and the contents of the abdomen push through to the outside. Occasionally, this occurs following surgery for another disease, in which case it is referred to as an incisional hernia.

An inguinal hernia forms when part of the intestine pushes through the abdominal wall, causing a bulge in the groin. Hernias may also form around the umbilicus (bellybutton) or along the middle of the abdominal wall. 

Repair of hernias may be done through open operations or laparoscopically - both options have benefits and disadvantages. The operations can often be performed as day-stay procedures and may require the use of a mesh - best to speak to your surgeon about which options are best for you.
