Hernia is one of the most common surgical diseases in general population. It is a condition in which part of an intraabdominal organ is displaced and protrudes through a weak point in the abdominal wall. The most usual types of hernia are named after the site of occurrence e.g. inguinal, umbilical, femoral etc. Back in the old days, surgery was performed by suturing the gap (herniorrhaphy), a technique that resulted in postoperative pain and high rate of recurrence. Today, modern synthetic mesh are used for "patching" the gap, thus causing significally less pain and lower recurrence rate.
